passage 1
A snake﹣robot designer，a technologist，an extradimensional physicist and a journalist walk into a
room.The journalist turns to the crowd and asks：Should we build houses on the ocean？Like a think﹣tank
panel，members of the team dream up far﹣out answers to the crucial problem，such as self﹣driving housing
units that could park on top of one another in the coastal city center.
The setting is X，the enterprise which considers more than 100 ideas each year，in areas ranging from
clean energy to artificial intelligence.Although only a tiny percentage become "projects" with far﹣reaching
creativity，these projects exist，ultimately，to change the world，like Waymo，the biggest self﹣driving﹣
car company.In the past 60 years，something strange has happened.As the academic study of creativity has
thrived （蓬勃发展），the label innovation may have covered every tiny change of a soda can or a toothpaste
flavor，but the rate of productivity growth has been mostly declining since the 1970s.John Fernald，an
economist，points out that the notable exception to the post﹣1970 decline in productivity occurred when
businesses throughout the economy finally figured out the breakthrough technology﹣information
technology.John Fernald says， "It's possible that productivity took off，because we picked all the low﹣
hanging fruit from the IT wave. "Actually，the world economy continues to harvest the benefits of IT.But
where will the next technology shock come from？
Breakthrough technology results from two distinct activities﹣invention and innovation.Invention is typically
the work of scientists and researchers in labs, while innovation is an invention put to commercial use. Seldom
do the two activities occur successfully under the same roof.They tend to thrive in opposite conditions；while
competition and consumer choice encourage innovation，invention has historically progressed in labs that are
protected from the pressure to generate profit.
Allowing well﹣funded and diverse teams to try to solve big problems is what gave us the computer and the
Internet.Today，we fail to give attention to planting the seeds of this kind of ambitious research，while
complaining about the harvest. "Companies are really good at combining existing breakthroughs in ways that
consumers like.But the breakthroughs come from patient and curious scientists，not the rush to market，" says
Jon Gertner，the author of The Idea Factory.
"Technology is a tall tree， " John Fernald said. "But planting the seeds of invention and harvesting the
fruit of innovation are entirely distinct skills，often mastered by different organizations and separated by manyyears. " As for me，both of them are essential for technology，although they are relatively independent.I don't
think X is a planter or a harvester，actually.It is like building taller ladders.Nobody knows for sure what，if
anything，the employees at such enterprises are going to find up on those ladders.But they're reaching.At least
someone is.

passage 2
Technology seems to.discourage slow，immersive reading.Reading on a screen，particularly a phone
screen，tires your eyes and makes it harder for you to keep your place.So online writing tends to be more
skimmable and list﹣like than print.The cognitive neuroscientist Mary Walt argued recently that this "new
norm" of skim reading is producing "an invisible，game﹣changing transformation" in how readers processwords.The neuronal circuit that sustains the brain's capacity to read now favors the rapid absorption of
information，rather than skills developed by deeper reading，like critical analysis.
We shouldn't overplay this danger.All readers skim.Skimming is the skill we acquire as children as we learn
to read more skillfully.From about the age of nine，our eyes start to bounce around the page，reading only
about a quarter of the words properly，and filling in the gaps by inference.Nor is there anything new in these
fears about declining attention spans （持续时间）.So far，the anxieties have proved to be false alarms.
"Quite a few critics have been worried about attention span lately and see very short stories as signs of cultural
decline， " the American author Selvin Brown wrote. "No one ever said that poems were evidence of short
attention spans. "
And yet the Internet has certainly changed the way we read.For a start，it means that there is more to
read，because more people than ever are writing.If you time travelled just a few decades into the past，you
would wonder at how little writing was happening outside a classroom.And digital writing is meant for rapid
release and response.An online article starts forming a comment string underneath as soon as it is published.This
mode of writing and reading can be interactive and fun.But often it treats other people's words as something to
be quickly harvested as fodder （素材）to say something else.Everyone talks over the top of everyone else，
desperate to be heard.
Perhaps we should slow down.Reading is constantly promoted as a social good and source of personal
achievement.But this advocacy often emphasizes "enthusiastic"， "passionate" or "eager" reading，none of
which adjectives suggest slow，quiet absorption.
To a slow reader，a piece of writing can only be fully understood by immersing oneself in the words and
their slow comprehension of a line of thought.The slow reader is like a swimmer who stops counting the number
of pool laps he has done and just enjoys how his body feels and moves in water.
The human need for this kind of deep reading is too tenacious for any new technology to destroy.We often
assume that technological change can't be stopped and happens in one direction，so that older media like "dead
﹣tree" books are kicked out by newer，more virtual forms.In practice，older technologies can coexist with
new ones.The Kindle has not killed off the printed book any more than the car killed off the bicycle.We still
want to enjoy slowly﹣formed ideas and carefully﹣chosen words.Even in a fast﹣moving age，there is time
for slow reading.
（1）What is the author's attitude towards Selvin Brown's opinion？A.Favorable.
B.Critical.
C.Doubtful.
D.Objective.
（2）The author would probably agree that .
A.advocacy of passionate reading helps promote slow reading
B.digital writing leads to too much speaking and not enough reflection
C.the public should be aware of the impact skimming has on neuronal circuits

passage 3
Learning doesn't have to end when people age.In fact，today's seniors want to remain socially engaged，
intellectually stimulated（智力上活跃的），and an active part of their communities according to The
American University Beirut（AUB）in Lebanon.That's why AUB opened The University for Seniors that gives
older adults—50 and up—an opportunity for lifelong learning.
"The goal of the program is to establish a community for seniors to learn for life，most of whom are
retirees，"Mira Zaatari，the program assistant manager told Al﹣Fanar Media."They can stay engaged
physically and mentally here."
The university includes two three﹣month semesters and students can take any class they want regardless of
their educational level.There are no exams or graduation certificates.This school is all about lifelong
learning.The available classes include political science，public health，agriculture，sciences，women's affairsas well as creative classes about drawing，painting and music.Language classes include English，French and
Spanish.The classes are taught by volunteers，including AUB professors，students，and doctors from the
university's hospital.
Seniors can gain a host of benefits by continuing to learn new things.According to Aging Well，that's
because lifelong learning keeps the brain stimulated，challenged and fully engaged."This helps seniors remain
mentally alert while they age.In fact，when people learn new things，the brain—even an older brain—can
form new connections and pathways，"it adds.
Keeping physically active is important and so is keeping social connections.That's why the university
provides more than just education.
Former banker Youssef Bakri，84，has been a student for over 10 years.He pointed out that before the
pandemic the university garden was used as a meeting place for socialization and that there were organized field
trips.
With the percentage of over 65s in Lebanon's population growing and the fact that many of these seniors live
alone without family members in the country，The University for Seniors is playing a very important role in the
lives of its students.
（1）Why does AUB launch the program？
A.To do some scientific research on seniors.
B.To promote learning among young people.
C.To encourage seniors to do volunteer work.
D.To offer a lifelong learning place for seniors.
（2）What can the students do at The University for Seniors？
A.Get free medical treatment.
B.Pass final exams as a group.
C.Choose their classes at will.
D.Obtain graduation certificates.
（3）Aging Well is mentioned in paragraph 4 to .
A.explain why learning can benefit seniors
B.show the working principle of the brain
C.offer advice on how to learn new things
D.analyze the advantages of accepting aging（4）What is the author's opinion on The University for Seniors？
A.It is far from suitable for seniors.
B.It has trouble in attracting students.
C.It is of great value for its students.
D.It cares little about its students' health.
passage 4
Computer games have seriously caught the attention of Mass Media.The increasing amount of games with
violent scenes socks the society and makes it very aware of them.The fact that violent games cause violence in
people is not even doubted by most people.Some say that the reason lies in games being too close to reality.But
is it justified only according to the external similarity of these two worlds？
Games originally are entertainment.Contemporary games are very realistic and for this reason they are a
source of great experience for the player and develop the imagination.Games are more than entertainment.The
research of the New York University led by Green and Bavelier claims that the player preferring active games
get an improvement of some types of brain activity，related to processing of visual information.In particular，
game players cope with problems of simultaneously（同时地）tracking several moving objects at the average
level of 30%better than people who do not play active computer video games.A game is an abstraction.A player
gets abstract tasks and acts according to abstract rules.Games are also the possibility to be whoever a person
wants to be and to rest from the outside world for some time.
But what if a person gets so much excited with the game scenes that he becomes violent in reality？Then，
it proves that the games cause people to become violent.A psychologically healthy person will never confuse or
connect these two different worlds.A game is a virtual world with visual images very similar to human.These
images represent by themselves nothing but simple playing obstacles.A game may potentially give the
opportunity to"destroy the obstacles"that may not be destroyed according to the rules，but it is more about
personal choice whether to do it or not.This leads us to the conclusion that violence is not a consequence but the
cause.People who originally tend to violence may get annoyed by games and perform violence in the"real
world".In this case violence in games is a simple justification of the violent nature of the player.

passage 5
Many people have participated into lots of virtual meetings these years.Some research shows this
adjustment might not impact workplace productivity to any great degree.A new study，though，suggests
otherwise.
In the study，602 participants were randomly paired and asked to come up with creative uses for a
product.They were also randomly selected to work together either in person or virtually.The pairs were then
ranked by assessing their total number of ideas，as well as those concepts' degree of novelty，and asked to
submit their best idea.Among the groups，virtual pairs came up with significantly fewer ideas，suggesting that
something about face﹣to﹣face interaction generates more creative ideas.The findings could stiffen
employers' resolve to urge or require their employees to come back to the office.
"We ran this experiment based on feedback from companies that it was harder to innovate with remote
workers，"said lead researcher Melanie Brucks."Unlike other forms of virtual communication，like phone
calls or e﹣mail，video conferencing copies the in﹣person experience quite well，so I was surprisedwhen we found meaningful differences between in﹣person and video interaction for idea generation."
When random objects were placed in both the virtual and physical rooms，the virtual
pairs of participants spent more time looking directly at each other rather than letting their look wander about
the room and taking in the entire scene.Eyeing one's whole environment and noticing the random objects
were associated with increased idea generation.On platforms ， the screen occupies our
interactions.Our look wavers less."Looking away might come across as rude，"said Brucks，"so we have to
look at the screen because that is the defined context of the interaction，the same way we wouldn't walk to
another room while talking to someone in person."
Like most educators，Brucks has primarily taught virtually in the past three years，and she did notice
some benefits of the approach as well.Her students were more likely to take turns speaking and her shyer
students spoke up more often，rid of the anxiety that comes from addressing a large classroom.Brucks found
that one solution to improving virtual idea generation might be to simply turn off the camera，for her students
felt "freer"and more creative when asked to do so.And this may be sound advice for the workplace Virtual
teamwork can't replace face﹣to﹣face teamwork.Idea selection proficiency（能力） is only valuable if you
have strong options to select from，and face﹣to﹣face teams are the best means to generate winning
options.Perhaps the workplace will find a compromise— a sweet spot in the middle that balances working from
both home and office.
（1）What does the underlined word"stiffen"in Paragraph2 most probably mean？
A.Shake.
B.Revise.
C.Challenge.
D.Strengthen.
（2）At first，lead researcher Melanie Brucks might think that .
A.video conferencing can't compare with in﹣person communication
B.participants should make eye contact in an online meeting
C.the feedback from companies seems questionable
D.creative ideas may emerge from casual thoughts
（3）What can we learn about Brucks' class？
A.Her students relieved anxiety by speaking up.
B.Her students progressed in focusing attention.C.Her students took advantage of virtual learning.
D.Her students displayed talent for public speaking.
（4）Which of the following would be the best title for the passage？
A.Interacting Virtually Impacts Working Participation
B.Maintaining Teamwork Improves Idea Generation
C.Grouping Randomly Increases Productivity
D.Brainstorming Online Limits Creativity
passage 6
Imagine wearing high﹣tech body armor （盔甲） that makes you super strong and tireless.Such
technology，more specifically called an exoskeleton，sounds like the preserve of the Iron Man series of
superhero movies.Yet the equipment is increasingly being worn in real life around the world.And one
manufacturer—California's SuitX expects it to go mainstream. "There is no doubt in my mind that these devices
will eventually be sold at hardware stores，" says SuitX's founder Homayoon Kazerooni.
In simple terms，an exoskeleton is an external device that supports，covers and protects its user，giving
greater levels of strength and endurance.Sometimes also referred to as "wearable robots"，they can be battery﹣
powered and computer﹣operated，incorporating motors and hydraulics.Or they can be more simple，passive
designs that use springs and dampeners.
"Integrating humans and machines into one system opens up a new realm of opportunity，" says Adrian
Spragg，an expert on the technology at management consultancy Accenture. "Many of the early applications
have been focused on military and medical applications，but in the last several years there's been an explosion
of use in a range of cases." This expansion，which has come together with rapid advances in the technology，
has seen exoskeletons increasingly used by manufacturing workers.Versions for consumers are also now being
developed to help people more easily do everything from DIY，to walking，climbing stairs，and other daily
activities.One report says sales are now due to rocket as a result.Global exoskeleton revenues （收入） are
expected to explode from ＄ 392 million in 2020 to ＄6.8 billion in 2030，according to a study by ABI
Research.
SuitX's "suits" are now being tested by car manufacturers General Motors and Fiat.Prof Kazerooni，who is
also the director of the University of California's Berkeley Robotics and Human Engineering Laboratory，says
that the primary benefit of the firm's exoskeletons is to prevent muscle fatigue （疲劳）.
"In general I see this development as very positive for occupational health and safety，" Prof SandraWachter says. "Machines are supposed to help us with dull，dangerous and dirty jobs.Problems，however，
arise if robotics also double as workplace monitors.Are these suits tracking your movements，how fast you
move，and how often you take breaks？Does a system compare this data with those of other workers to score
or rank them？What happens if you move slower than others，or take breaks more often？"

passage 7
Interactive software that "reads" and analyses footprints left by black rhinos （犀牛）can be used to
monitor the movements of the animals in the wild，giving conservationists a new way to keep watch on the
endangered species and help keep it safe from poachers （偷猎者），according to a Duke University﹣led
study.The software，called the Footprint Identification Technique （FIT），uses advanced technology to
analyze more than 100 measurements of a rhino's footprint.Because each rhino's footprint is as special as a
human fingerprint，the analyzed images can be collected electronically in a global database of previously
collected footprint images for matching.
"If you find a match，you can identify the individual animal who left the mark and，by plotting the
locations of all the other places where marks have been seen，track its movements without disturbing it or
coming into close enough contact with it，" said Zoe Jewell，a professor at Duke University's Nicholas School
of the Environment，who co﹣led the study and is co﹣creator of FIT.
"It's a cost﹣effective approach that not only protects the health of the rhino and the human，but also
brings a centuries﹣old tracking skill into the 21st Century，" she said.Jewell and her colleagues are now
working with Namibia's Ministry of Environment，Forestry and Tourism to train wildlife conservationists，
land managers and local guides how to use FIT.
Namibia is home to an estimated 2，000 black rhinos，or about 90% of the species' total population
worldwide.Though legally owned by the government，the animals are distributed geographically on private
lands across the country.
The FIT software can also do a survey of footprints throughout the protected area and take measurements
from each footprint to estimate the number of rhinos in that area.This can be useful information for calculation
resource needs to monitor the animals effectively.This creates an interactive library that anti﹣poaching patrols
（反偷猎巡逻）can use to search for animals at the highest risk，including those whose footprints haven't
been showing up in recent years.
（1）What is the purpose of the software？
A．To promote the development of technology.
B．To protect black rhinos from being hunted.
C．To analyze the footprints of illegal poachers.
D．To save endangered species across the world.
（2）What's the advantage of the software？
A．It owns various functions.
B．It goes to the market.
C．It is perfectly practical.
D．It is more than popular.（3）What does Zoe Jewell say about the approach？
A．It brings the best advantage for the lowest cost.
B．It helps increase the population of black rhinos.
C．It raises people's awareness of the environment.
D．It strengthens the tie between humans and nature.
（4）Which of the following best describes the future of rhinos？
A．Optimistic.
B．Hopeless.
C．Worrying.
D．Uncertain.
passage 8
Artificial intelligence helps teachers identify which of their students have learning difficulties，according
to a new study.
Teachers make more accurate assessments of learning difficulties among their students if they are given Al﹣
generated feedback （反馈） rather than an "expert solution" written by a qualified professional.Researchers
believe that because the AI analyzed the teacher's own work，it's easier for the teacher to understand than a
"model answer" prepared beforehand.
"Teachers play a critical role in recognizing the signs of disorders and learning difficulties in pupils and
referring them to specialists，" said Riikka Hofmann. "Unfortunately，many of them feel that they have not
had sufficient opportunity to practice these skills.AI could provide an extra level of individualized feedback to
help them develop these essential competences."
Trainee teachers were asked to assess fictionalized students for potential learning difficulties，based on
evidence including examples of their work，school behavior records and written texts of conversations with
parents.Half of the trainees received the "expert solution"，typical of the material given to trainee teachers，
while the other half received AI﹣generated feedback on their approach ，highlighting where they could
improve.The trainees then completed similar follow﹣up assessments，and were graded both on the accuracy of
their diagnoses （诊断） and on how well they had used the evidence.Trainees who received the AI feedback
scored significantly higher than those who worked with the pre﹣written expert solutions.
While the researchers said this does not mean AI is preferable to one﹣to﹣one feedback from a skilled
expert，this is not always available for trainee teachers. "We are not arguing that AI should replace teacher﹣educators：new teachers still need expert guidance on how to recognize learning difficulties in the first place，"
said Dr Michael Sailer. "It does seem，however，that AI﹣generated feedback helped these trainees to focus on
what they really needed to learn.When personal feedback is not readily available，it could be an effective
substitute （代替物）."
（1）What does the underlined word "them" refer to？
A．Pupils.
B．Teachers.
C．Specialists.
D．Researchers.
（2）What did AI help trainee teachers know in the study？
A．How well they had used the evidence.
B．Whether the expert solution was accurate.
C．Where their approach needs improvement.
D．What follow﹣up assessments they completed.
（3）What does Dr Michael think of AI？
A．It will take the place of skilled experts.
B．It acts as an expert guide to trainee teachers.
C．It is only suitable for new teachers to use.
D．It can be a useful teaching training aid.
（4）Which of the following is a suitable title for the text？
A．AI locates learning difficulties for the students
B．AI becomes an effective teaching tool in school
C．AI helps teachers spot students with learning difficulties
D．AI trains teachers in judging the learning of the students

passage 10
Using the power of artificial intelligence （AI），scientists have revealed new insights into the creation
and destruction of mass extinction.Contrary to conventional knowledge，their study suggests that larger
extinctions are not always a form of "creative destruction" that allows new organisms to radiate （向周围辐射
出去）and evolve.Instead，it suggests that mass extinction is rarely associated with new species of radiation.
Dr.Hoyal Cuthill，the lead study author from the University of Essex in the UK and the Tokyo Institute of
Technology，said in a statement， "Some of the most challenging things to understand the history of life are
the vast timelines involved and the number of species.New machine learning applications can help us
understand the information in human﹣readable form.This means that we can，so to speak，hold the evolution
of half a billion years in the palm of our hand and gain new insights from what we see."
They concluded that mass extinction and later radiation were not connected as previously thought.Within 5
percent of the most significant periods of disruption（中断），AI detected "big five mass extinctions，seven
more mass extinctions，two mass extinction﹣radiation events and 15 mass radiations.Most importantly，it
discovers that massive radiation and extinction rarely occurred with each other，changing the view that greater
extinction leads to a kind of deep cycle﹣like species radiation of nature.It appears that larger extinctions are
certainly not the engine of evolutionary radiation.Take the Cambrian Explosion for example and it was about 41
million years ago when a large group of animals first appeared on the first fossil record and the dawn of a high
mobile animal equipped with modern physical features.
This new study found that a handful of other notable explosions of biodiversity，including the Cambrian
Explosion，usually occurred at a time when they were largely isolated（孤立的）from extinction.Dr.Nicholas
Guttenberg，a study co﹣author from the Tokyo Institute of Technology explained， "Ecosystems are dynamic
and you don't need anything to exist to allow something new to appear."
（1）What's the function of the first paragraph？
A.To analyze the cause of creative destruction.B.To tell us the result of the new study.
C.To explain the power of artificial intelligence.
D.To present the conventional idea of mass extinction.
（2）What do Dr.Hoyal Cuthill's words imply？
A.New AI machines learn applications better.
B.It's difficult to understand the history of life.
C.New species appear before mass extinction.
D.AI contributes a lot to the study of evolution.
（3）Why is the Cambrian Explosion mentioned in the text？
A.To provide knowledge of history.
B.To highlight the importance of AI.
C.To support the new study.
D.To prove the previous view is right.
（4）What is the text mainly about？
A.A new understanding of mass extinction.
B.The processes of biological evolution.
C.Animal species with modern physical features.
D.The relationship between mass extinction and radiation.
passage 11
As the concept of emotional intelligence （EI） has gone global，we've watched professionals fail as
they try to improve their emotional intelligence because they either don't know where to focus their efforts or
they haven't understood how to improve these skills on a practical level.In our work consulting with companies
and coaching leaders，we have found that if you're looking to develop particular EI strengths，it helps to
consider areas for improvement others have identified along with the goals you want to achieve﹣and then to
actively build habits in those areas rather than simply relying on understanding them conceptually.
The first step is to get a sense of how your self﹣perception （how you see yourself） differs from your
reputation （how others see you）.This is especially true for the development of EI because we can be blind to
how we express and read the emotional components of our interactions.For example，most of us think that
we're good listeners，but very often that's really not the case.Without this external reality check，it will be
difficult for you to identify the ways that your actions affect your performance.Getting feedback from others canalso provide proof of the necessity of shifting our behavior and motivation to do so.
To give you the best sense of where the differences lie between your self﹣perception and reputation，you
should use a 360﹣degree feedback assessment that takes into account the multiple aspects of EI.The key is to
find one to give you feedback，which is focused on development and not on performance assessment.And that
can give you a detailed understanding of how other people's assessments of you differ from your own
assessments.
Secondly，when you get your feedback from an assessment，let that inform what you want to
improve.But also consider what your goals are.When it comes to cultivating strengths in emotional
intelligence，you're at a huge disadvantage if you're only interested because others say you should be.Your
emotional intelligence is so tied up in your sense of self that being intrinsically （内在的） motivated to make
the effort matters more when changing longstanding habits than it does when simply learning a skill.
That means the areas that you choose to actively work on should lie at the intersection of the feedback you've
gotten and the areas that are most important to your own aspirations.Understanding the influences of your
current EI habits relative to your goals will keep you going over a long period of time as you do the work of
strengthening your emotional intelligence.

passage 12
Researchers have designed a 4 D﹣printed soft robot that self﹣assembles （自动组装） when heated
and can take on challenging tasks like rolling uphill and navigating an unpredictable landscape.
"Like an insect with antennae （天线），the robot can overcome a small obstacle.But when the obstacle
is too high，it will turn back and never come back，" says senior author Wei Feng，a materials scientist at
Tianjin University in China. "The whole process is finished by itself without human's control."
When the surface beneath it is heated，the robot form a tube like a spring.The change in shape adds time
as a fourth dimension （维度）to the printing process，making it 4 D．
Once the robot forms a tube，the contact from the hot surface causes a response in the material，which
causes it to roll in one direction.The driving force behind this motion is so strong that the robot can climb up a
20° incline （斜度） or even carry a load 40 times its own weight.The length of the robot affects its speed，
with longer robots rolling faster than the shorter ones.
The researchers caught videos showing off the robot's skills，including a race between differently sized
robots and another robot carrying a cart.The videos also show how its behavior changes based on its
surroundings，with the robot either climbing up a step or changing directions when encountering a difficult
obstacle.
For Feng，the behavior of the robot came as a surprise.He says， "We found many interesting driving
phenomena besides the change of shape." In the future，these soft robots may be used to perform work in
small，limited places like in a pipe. "We hope that soft robots will no longer be limited to simple actuators
（驱动器），which can only change shape in a fixed position，" says Feng.
（1）What will the robot do when an obstacle is beyond its reach？
A．Give up reaching it.
B．Go back to ask for help.
C．Search for another one.D．Turn to the people around.
（2）What will happen when the robot is heated？
A．It will become a spring.
B．It will change faster.
C．It will change its shape.
D．It will be out of control.
（3）What can affect the rolling speed of the robot？
A．How heavy it is.
B．How long it is.
C．What it looks like.
D．What direction it rolls in.
（4）How does Feng expect the robot to become？
A．More beautiful.
B．More accessible.
C．More convenient.
D．More powerful.
passage 13
A new kind of solar panel，developed at the University of Michigan，has achieved high efficiency in
transforming water into hydrogen and oxygen—imitating a crucial step in natural photosynthesis（光合作
用）.The outdoor version of the experiment，with less reliable sunlight and temperature，achieved 6.1%
efficiency at turning the energy from the sun into hydrogen fuel.However，indoors，the system achieved 9%
efficiency.
But the biggest benefit is driving down the cost of sustainable hydrogen.This is enabled by reducing the size
of the semiconductor（半导体），typically the most expensive part of the device.The team's self﹣healing
semiconductor withstands concentrated light equivalent to 160 suns.
"We believe that artificial photosynthesis devices will be much more efficient than natural
photosynthesis，which will provide a path toward carbon neutrality，" said Zetian Mi，U﹣M professor of
electrical and computer engineering who led the study reported in Nature.
The new technology has two advances.The first is the ability to concentrate the sunlight without destroying
the semiconductor that traps the light. "We reduced the size of the semiconductor by more than 100 times
compared to some semiconductors only working at low light intensity，" said Peng Zhou，U﹣M researchfellow in electrical and computer engineering and first author of the study. "Hydrogen produced by our
technology could be very cheap."
And the second is using both the higher energy part of the solar spectrum（光谱） to break down water
and the lower part of the spectrum to provide heat that encourages the reaction.The magic is enabled by a
semiconductor catalyst（催化剂） that improves itself with use，resisting the degradation（降解） that such
catalysts usually experience when they trap sunlight to drive chemical reactions.
The next challenges the team intends to tackle are to further improve the efficiency and to achieve superhigh
purity hydrogen that can be directly fed into fuel cells.
（1）What leads to the lower cost of sustainable hydrogen？
A．Solar energy.
B．Smaller semiconductors.
C．Natural photosynthesis.
D．More concentrated light.
（2）What is an advantage of the new technology？
A．A catalyst easily available.
B．Creative use of the solar spectrum.
C．Outstanding ability to reflect light.
D．A semiconductor working at low light intensity.
（3）Why are the two advances of the new solar panel mentioned？
A．To introduce a greener lifestyle.
B．To promote its commercial value.
C．To state its technical breakthrough.
D．To advertise the potential application.
（4）Which of the following is the best title for the text？
A．A．New Trend in Water Usage.
B．The Future of Sustainable Hydrogen.
C．Solar Energy：More Efficient，Greener.
D．Cheaper Hydrogen Through Solar Power.
passage 14First the robots came for our jobs.Now they're coming for our hobbies.Google's DeepMind AI lab has been
busy the past few years，creating programs to take on human players across a variety of games.In 2016 its
AlphaGo beat the best Go player in the world.Earlier this year，its Alpha Star defeated two middle﹣tier
players at the popular online game StarCraft II.Now it's learning to win at multiplayer games.
"Artificially intelligent agents are getting better and better at two﹣player games，but most real﹣world
endeavors require teamwork，" DeepMind's researchers wrote in a paper published in Science in June.
To be sure，computers have been proving their dominance （优越） over humans in one﹣on﹣one turn
﹣based games such as chess ever since IBM's Deep Blue beat Russian chess master Garry Kasparov in 1997.
However，successfully using teamwork to win in multiplayer games with complex environments was
difficult to achieve.
For this purpose，DeepMind's researchers designed AI agents that taught themselves how to play first﹣
person game Quake III Arena.The team，led by Max Jaderberg，worked on a modified （修改的） version
of Quake III Arena.
The game mode they chose was "Capture （抢） the Flag".All the players must work together to steal the
other team's flag while safeguarding their own.
The AI agents "trained" with 12 hours of game data，then matched up against professional game
testers.The AI won 75 percent of the time，even when its reaction time artificially slowed down to human
levels and when their aiming ability was similarly reduced.
And in order to make improvements，the programmers used various kinds of "rewards" to help the AI
players weigh their goals and actions to help them cooperate in the teamwork.They also used randomized maps
for each new match.
"That meant the solutions that the agents find have to be general– they cannot just memorize a sequence
（系列） of actions，" said co﹣author Wojciech Czarnecki.
The only time humans were able to beat the AI agents was when they teamed up together.A team consisting of
one human and one AI agent had a five percent greater win probability than a team of just AI agents.
Ethan Gach said at the video game news website Kotaku， "It suggests that the AI program is able to adapt to
playing with non﹣AI teammates." In the near future，AI may cooperate with human beings in some other
fields，such as medicine and other branches of science.
（1）What might be the most difficult task for AI agents in multiplayer games？
A．Understanding the rules.B．Cooperating with other players.
C．Memorizing complex actions.
D．Increasing reaction speed.
（2）How did the researchers of Google's DeepMind train AI agents？
A．They gave various "punishments" when AI agents lost the games.
B．They made AI agents team up with non﹣professional human players.
C．They limited the time for AI agents to complete difficult tasks.
D．They put them through thousands of games with different situations.
（3）What does Gach mean in the last paragraph？
A．AI players perform better than humans in a team game.
B．AI programs should be offered more game data.
C．AI players are able to do well with human players.
D．AI programs have been successfully applied in the field of medicine.
（4）The underlined word "randomized" in Paragraph 8 can be understood as .

C．Teaming up with AI
D．AI Competing with Human Beings
passage 15
Technology caused the problem of false news，and it's easy to think that technology can solve it and that
we only need to find the right technology to solve the problem.But this approach ignores valuable lessons
concerned with how we acquire knowledge.
To understand how false news comes，start with an example.Imagine you're out for drinks when one of
your friends shocks the table with an unproven story about a local famous people.The story is so shocking
you're not sure it could be right.But then，here's your good friend，putting their reputation on the line.Maybeyou should believe it.
This is an instance of what philosophers call testimony （证词）.It's similar to the sort of testimony given
in a courtroom，but it is less formal and much more frequent.Testimony happens any time you believe
something because someone else proves the accuracy of the information.Most of our knowledge about the world
is secondhand knowledge that comes to us through testimony.After all，we can't each do all of our own
scientific research，or make our own maps of distant cities.
Social media has strange testimonial rules，and it is hard to solve the problem of false news.On
Facebook，Twitter and similar platforms，people don't always mean what they say，and we don't always
expect them to.A the informal Twitter：advertisement goes： "A retweet （转发推文） is not an approval."
When a well﹣known politician was caught retweeting false statistics about race and crime，he told Fox News
it wasn't a big deal： "am I gonna check every statistic？All it was is a retweet.It wasn't from me."
Intellectually （理智上），we know that people do this all of the time on social media，and pass along news
without checking its accuracy，but many of us listen to them anyway.The information they share is just too
attractive to ignore﹣especially when it is about our existing political beliefs.
（1）Why do we tend to believe surprising news over drinks？
A.We've confirmed it.
B.We may be drunken.
C.We find it amazing.
D.We trust in our friends.
（2）What does the underlined word "it" refer to in paragraph 3？
A.The statement in court.
B.The talk in a restaurant.
C.The evidence of a crime.
D.The testimony of a philosopher.
（3）Why is it easy for us to believe the content producers on social media？
A.We are tolerant of their actions.
B.Social media have issued odd regulations.
C.We will identify with them readily.
D.Social media don't check the information.
（4）What may be the best title for the text？A.How to Fix False News
B.How Incorrect Information Arrives
C.What Information to Acquire
D.When Testimony Disturbs Audience
passage 16
While most of us are never without our smartphones ， robots may also soon become essential
companions.It certainly seems so based on the recent experiments conducted by researchers in Japan，who
developed a wearable soft robot for patients to use during treatments，such as injections（注射）and other
unpleasant therapies in an attempt to ease their pain and defend people against anxiety.On being subjected to a
moderate heat stimulus（刺激），the study participants who wore the robot experienced less pain than in the
tests in which they did not wear the robot.
During the campaign to encourage vaccination against COVID﹣19，public health officials recognized
that some people are simply afraid of needles，which contributed to reduced vaccination rates.While the
problems of patient anxiety and pain during medical procedures have been well studied，there remains a need
to test and implement solutions to help patients.
The soft fur﹣covered robot the scientists called Reliebo was designed to be attached to the participant's
hand.The researchers tested its effectiveness under various conditions based on the clenching of the participant's
hand，while applying the painful thermal stimulus to the other arm that was not being used to hold the
robot.The researchers found that holding the robot helped relieve the experience for patients regardless of the
experimental conditions used，and concluded that the feelings of well﹣being that can be created by human
touch may have also been activated by the robot."It is well known that interpersonal touch can reduce pain and
fear，and we believe that this effect can be achieved even with nonliving soft robots，"states Professor Tanaka.
This may be useful when actual human contact is not feasible，such as during pandemics.Future versions
of the robot might use a controlled gaze or even AR（augmented reality）technologies to help build a
connection with the patient or distract them from pain perception in various situations.
（1）What is the purpose of the robot？
A.To assist doctors in injecting accurately.
B.To help relieve people's pain from injections.
C.To evaluate patients' physical and mental health.D.To assess the effects of getting vaccinated against COVID﹣19.
（2）How does the robot ease the pain and anxiety of the patients？
A.The robot is designed to be attached to the patients' hand.
B.The robot's soft fur gives the patients a feelings of well﹣being.
C.The robot's"interpersonal touch"creates a feelings of well﹣being.
D.The robot instructs the researchers to relieve the experience for patients.
（3）What will researchers probably do next？
A.Develop other devices for medical treatment.
B.Carry out more and more tests on the robot.
C.Evaluate the possible risk of using the robot.
D.Promote the application of the robot worldwide.
（4）Which of the following can be the best title for the passage？
A.How to Reduce People's Fear of Injections.
B.Advanced Technology Helps to Cure Patients.
C.Being Afraid of Needles Reduced Vaccination Rates.
D.Wearable Soft Robot Helps People Scare of injections.
passage 17
A battery made of paper stands out among the 200 best inventions of the year in TIME Magazine. "It
sounds impossible：Just add water to a piece of paper and get energy，" said TIME Magazine，who chose the
Swiss﹣made battery as one of the winners in this year's "Experimental" inventions.
The battery was created by researchers at the Swiss Federal Laboratory for Materials Testing and Research.
"Over the last decades，we have witnessed an increasing use of electronic devices，leading in turn to electronic
waste （e﹣waste）becoming the world's fastest growing waste stream." wrote the researchers in their
published paper.They developed the paper battery aiming to reduce the environmental impact of single﹣use
electronics by turning to more environmentally friendly materials.
The battery was described to be made from paper with salt inside and based on printed inks：two kinds of
inks containing different minerals acted as the positive end and the negative end.Analysis of the performance of
a one﹣cell paper battery showed that after two drops of water were added，the battery started working within
20 seconds and reached a stable voltage （电压） of 1.2 V.After one hour，the one﹣cell battery's
performance dropped significantly as the paper dried out.But after the researchers added two extra drops ofwater，its performance increased with a stable voltage of 0.5 V for another hour.
Within two to five years，the technology could be used in low﹣power electronics such as medical devices
and smart packaging. "I see a new role for paper...that could also be an answer to the growing concern over e﹣
waste，" said EMPA's Gustav Nyström，the inventor.He told TIME Magazine they wanted to improve the
efficiency of the battery in the futured and get it working for longer.

passage 18
Radio stations，TV stations，and online video and livestreaming platforms are forbidden to make，
broadcast or spread programs that feature overeating，according to a new work plan issued by the NationalDevelopment and Reform Commission，together with three other departments.
That's a positive move.It is easy to see from even a glimpse at any of the "big stomach" videos or
livestreams，in which the hosts may eat a dozen hamburgers for lunch，for example，that their eating
obviously exceeds a normal appetite.According to reports ， such "big stomach" eaters can attract large
audiences and more followers for commercial advertisements.
A good appetite can be healthy.Yet to promote such distorted eating is dangerous，not only to those doing
the eating on the shows but also anyone who may be tempted to emulate or compete with them，it can cause
eating disorders such as bulimia and can prove fatal.
In August 2020，a "big stomach" surnamed Wang in Shenyang city，Northeast China's Liaoning province
died when preparing for his job，before which his weight rose from 100 kilos to 140 kilos.In the same month，
a 3﹣year﹣ old girl called "Peppa" was found to weigh 35 kilos，far exceeding the normal weight，which
aroused nationwide worries about her health.
Those appearing in such videos or livestreamings are usually hired by companies with whole teams to finish
the job，and even then they often throw up during ad breaks so that they can continue their performances.And
as well as by encouraging people to eat so much it may harm their health，by creating the impression that it is
OK to eat to excess，such "big stomach" shows may lead to people wasting food.
Of course，that does not mean food videos or livestreamings should be curbed.A good food program can
teach people how to cook delicious dishes or showcase local specialties from around the country.It could also
spread the millenniums﹣long traditional food culture of China，which has made a deep impression on the
whole world and got many followers.
（1）What can we know about "big stomachs"？
A.They can draw many audiences and followers.
B.They can see videos or livestreams easily.
C.They are a positive move.
D.They often advertise their non﹣profit food.
（2）The underlined word "distorted" in Paragraph 3 can be replaced by .
A.exceptional
B.casual
C.abnormal
D.rigid（3）Which of the following is NOT the effects of "big stomach" video or livestreaming for the eaters？
A.They may arouse eating disorders and even death.
B.They may keep the eaters from throwing up.
C.They may mislead people into wasting food or overeating.
D.They may trigger some health problems such as overweight.
（4）What is the best title of the passage？
A.Food livestreamings should be banned
B.Food culture of China
C.Good appetite，good health
D.Love food，love life；don't envy "big stomachs"
passage 19
Teaching artificial intelligence to understand simple physics concepts，such as that one solid object can't
occupy the same space as another，could lead to more capable software that takes less computational resources
to train，say researchers at DeepMind.
Now，Luis Piloto at DeepMind and his colleagues have created an AI called Physics Learning through
Auto﹣encoding and Tracking Objects （PLATO） that is designed to understand that the physical world is
composed of objects that follow basic physical laws.
The researchers trained PLATO to identify objects and their interactions by using simulated（模 拟的）
videos of objects moving as we would expect，such as balls falling to the ground，rolling behind each other
and bouncing off each other.They also gave PLATO data showing which pixels（像素） in every frame or
photo belonged to each object.To test PLATO's ability to understand five physical concepts，such as solidity，
persistence （that an object doesn't tend to vanish） and unchangingness （that an object tends to retain
features like shape and colour），the researchers used another series of simulated videos.Some showed objects
obeying the laws of physics，while others depicted ridiculous actions.They tasked PLATO to predict what
would happen next in each video，and found that its predictions were reliably wrong for nonsensical videos，
but usually correct for logical ones，suggesting the AI has an intuitive（直觉的）knowledge of physics.
Piloto says the results show that an object﹣centric view of the world could give an AI a more generalised and
adaptable set of abilities. "If you consider，for instance，all the different scenes that an apple might be in，" he
says. "You don't have to learn about an apple on a tree，versus an apple in your kitchen，versus an apple in the
garbage.When you kind of separate the apple as its own thing，you're in a better position to generalise how it
behaves in new systems，in new contexts.It provides learning efficiency.""This is somewhat like teaching a kid what a car is by first teaching them what wheels and seats
are，"Chen Feng at New York University says."The benefit of using object﹣centric representation，instead of
raw visual inputs，makes AI learn intuitive physical concepts with better data efficiency."
（1）Why was PLATO created？
A.To help AI process more data.
B.To teach AI researchers how to use simple physics knowledge.
C.To enable AI to comprehend simple physics concepts.
D.To have objects follow basic physical laws.
（2）What does the third paragraph mainly talk about？
A.The purpose of the research.
B.The participants of the research.
C.The objects of the research.
D.The process of the research.
（3）What's the function of the example in paragraph four？

A.Unconcerned.
B.Critical.
C.Objective.
D.Indifferent.
passage 20
A group of researchers has developed a new material which is as soft as cotton but as strong as Kevlar and
as conductive as many metals.It can be worn and washed like normal clothing and could eventually turn athletic
clothes into smart "wearables".
The so﹣called "carbon nanotube（纳米管）threads" work similarly to the wires in an EKG （心电图）
monitoring device，which measures heart rhythms to detect heart conditions.But instead of having to be
patched（贴上）onto the skin，they can be sewn into a T﹣shirt and worn like normal athletic clothes，according to a new study from researches at a Rice University Brown School of Engineering lab.And unlike
wires.they say the threads can comfortably move with the wearer.and be washed ， stretched and worn
repeatedly without breaking down.
The Rice University lab first developed carbon nanotube fiber in 2013，and has studied its use in medical
operations，such as in cochlear（耳蜗的） implants for hearing loss and to repair damaged hearts.But at the
time，the original filaments （细丝） were too thin to be used by a standard sewing machine.
For this latest one，researchers worked with a rope﹣maker to weave the filaments together into a material
similar to regular sewing thread that could be sewn into athletic clothes.The resulting "smart" shirt provides
"soft，wearable，dry sensors for continuous" EKG monitoring，the study states.
Though likely a long way off from going into production for consumers.the material could eventually help
replace heavy EKG monitors in medical settings and heart rate monitoring watches.With some changes，clothes
with these fibers could eventually be able to track other vital signs，according to the researchers.
"You just don't find soft，flexible，thread﹣like materials that are comfortable to the touch，that you can
work with，that you can build a bridge or you can build a power line out of ，but you can also run it through a
sewing machine. " said Oliver Dewy，a member of the research team. "Nothing else behaves like this. "
