passage 1
Three Chinese astronauts landed in a northern desert on Sunday after six months in space.They had been
working（1） （ complete） the basic structure of the Tiangong space station，a symbol of the
country's（2） （ ambition） space program.A capsule carrying commander Chen Dong and
astronauts Liu Yang and Cai Xuzhe touched down at a landing site in the Gobi Desert in northern China at
approximately 8：10 pm.
Before leaving the Chinese space station，they had spent almost five days with three（3） （
colleague） who arrived on Wednesday in the Shenzhou﹣15 spaceship，（4） （ mark） the first
time China had six astronauts in space at the same time.
The astronauts（5） （ carry） out of the capsule by medical workers about 40 minutes after
landing.They all wore smiles and appeared to be in good condition，waving（6） （happy）at the
workers at the landing site.
The three astronauts were part of the Shenzhou﹣14 spaceship，（7） was launched in June.After
their arrival at Tiangong space station，Chen，Liu and Cai performed three spacewalks，held a live science
lecture from the station and conducted（8） range of experiments.
Tiangong space station will be the only space station still up and running in the universe one day（9）
the International Space Station（10） （ retire） by around the end of the decade as expected.
passage
The rise in children's screen time has brought about calls for（1） （great）interaction and more
outdoor exercise to improve learning and guard（2） the spread of shortsightedness.
Time spent online（3） （increase）dramatically in the past years.Millions of pupils have been
forced （4） （switch） to remote learning，according to Qustodio software，（5） tracks
usage of devices by children aged 4 to 15 in the UK，US and Spain.
One area of concern is eyesight.More occurrence of children's nearsightedness is likely caused by children
being kept at home with schoolwork delivered online.It is uncertain（6） the rise is caused by more
time spent on screens or less time outdoors ， but previous studies have suggested daylight （ 7 ）
（expose） is key.Another concern is about sleep problems among children.It is definitely clinically significant.There's evidence
that shows a sharp increase in children with sleep problems.A number of（8） （factor） may
account for it，with increased screen time being （9） .
Parents also worry about the impact of too much screen time on children's mental and emotional
development.Instead of interactions with their class，spending hours（10） （passive）sitting in front
of a screen may lead to stress and other mental health problems.
passage 3
Chinese smart phone makers are focusing on foldable smartphones to wrap up the year of fierce competition
in the high﹣end market.Huawei Technologies Co unveiled （ 发 布 ） the P50 Pocket ， its （ 1 ）
（late）foldable handset，on Thursday.（2） （price）from 8，988 yuan（1，411）in China，the
model reflects Huawei's intention （3） （sharpen） its technical and foldable design capabilities，
market insiders said.

passage 4
For over a century ，student journalists at The Daily Tar Heel （ DTH ） have documented their
college life and raised（1） （ variety ） questions on free expression ，tuition ，and big ﹣ time
athletics...The independent student newspaper celebrated its 125th anniversary this year .To mark it ，student（2） （ report ） asked the question ：What ' s the future of the DTH ？
Student newspapers are faced（3） a dark reality.Falling advertising income ，increasing digital
demands and the lack of subscription fees as they are free（4） （ read ） mean that such
newspapers are finding them much（5） （ hard ） to survive .Most college papers have reduced
their print editions .And while the DTH（6） （ use ）to produce around 22，000 newspapers ，it
only makes around 10，000 now.
Increasingly，student journalists have turned their focus to their digital platforms（7） they can
tell stories with social media.And though（8） can be challenging for them to move away from that
print tradition，they manage to adapt very well.So what should student newspapers（9） （trap） in
this situation do？Perhaps the ideal answer would be for universities to（10） （financial） support
student journalism.In the meantime，college newspapers are figuring out their financial models as they go
along.
passage 5
Starlink，a new satellite Internet system from the company SpaceX， （1） （change） the
world more quickly nowadays than many people expected.Not only can the system be very useful in remote
areas and emergency situations， （2） it also presents several important problems.
Before Starlink，most satellite Internet service was based on satellites that （3） （constant）
remained above one point on Earth.This means that signals from farther away need to travel a long distance，
causing delays.
Starlink has a web of satellites moving in a low orbit around the Earth.Because the satellites are closer，
the speeds are（4） （fast）.This makes the service better for things that need to happen（5）
delays，like holding meetings over the Internet.
SpaceX isn't the only company （6） works to provide this kind of satellite Internet service.For
example，OneWeb is a British company （7） （develop） a similar satellite Internet service.But
Starlink is farther along than most others.Starlink currently works in 31（8） （country），but
SpaceX plans to expand the service （9） （cover） the whole world.
Astronomers have complained that Starlink satellites are causing light （10） （pollute）.This
makes it harder to study things in space without satellites getting in the way.SpaceX has worked to reduce the
light from Starlink satellites.passage 6
Chinese science﹣fiction writer Liu Cixin met with his Russian readers during Russian Creative Week via
video link on Sunday，（1） （share） his views on writing science fiction，the development of
science and technology in the future.
Liu also said that he was working on his new book but it might take some time to finish."Probably a year
（2） two，"Liu said.
Liu made a （3） （compare） of science fictions from different times."Science fictions in the
past had a broad vision，（4） （most） describing space and the universe，and （5）
（ it ） eyes were focused on the stars.Nowadays ， science fictions focus on realistic （ 6 ）
（problem），such as gender and race discrimination，environmental pollution and so on，"Liu said.
Liu， （7） is 58，said that he is trying to adapt his fiction for films and TV except for literary
writing.US streaming platform Netflix announced in September 2020 that it （8） （order） an
English﹣language series based （9） Liu's well﹣known trilogy The Three﹣Body Problem.He
wants the series （10） （be） attractive and well﹣made."As long as the series will be
interesting，I don't care how much the series change my book，"he noted.

Launch Center.
During the Shenzhou XII mission，the（2） （astronaut），Zhai Zhigang，who was the
mission commander，Wang Yaping and Ye Guangfu carried out two spacewalks（3） lasted more than
12 hours.Wang Yaping， （4） （know） as the first female Chinese spacewalker，took part in the
first spacewalk on November 7.
In an orbit about 400 kilometers above the Earth，the crew members also carried out two science lectures
for Chinese students.In one experiment，Wang used a Bing Dwen Dwen toy，the popular mascot of the Beijing
2022 Olympic Winter Games， （5） （display） how objects fly in（6） （weight）
environment.In early February，they spent Chinese Lunar New Year inside the station，appeared in（7）
live broadcast gala of CCTV and（8） （send） their best wishes to Chinese people.After orbiting Earth for six months，Shenzhou XIII spacecraft circled the Earth several times to（9）
（ gradual） approach it and returned to the mother planet on April 16.Medical service workers（10）
the scene told China Central Television that the crew members were in good condition.
passage 8
Uploading a picture or video from a scenic spot to sites such as Douyin and Kuaishou （1）
（know） in China as daka，meaning"punching the card".The aim is not to produce a well﹣crafted video or
beautiful photograph，but simply（2） （show） that you have also been to the places that are
popular.The beauty of the attractionis（3） （important） than the fact that people are flocking there
to daka.
A subculture has developed of young people（4） embrace daka as a lifestyle.So﹣called daka zu
—"daka tribes"—can be found wandering Chongqing and other cities，checking（5） at as many hot
locations as possible within a single day.
Just as shops and restaurants in other countries try to attract customers with decorations that might be a
backdrop（背景） for Instagram pictures，（6） in China try to make themselves as daka﹣friendly
as possible；a coffee shop（7） （build） inside a shipping container，for example.
The daka craze may have（8） （practice） origins.China's young urban professionals have
little vacation time.In their first year at a company，（9） （employ） can expect at most one day of
vacation，They are（10） （routine） expected to work overtime for no pay.So workers need to
make the most of their limited leisure time.Douyin captures the mood with its slogan："Make every second
count."
passage 9
In recent decades，exploring Mars（1） （be） the top agenda for several countries.（2）
latest news reveals an exciting fact：China's Tianwen﹣1 spacecraft has landed on a site on a vast plain known
as Utopia Planitia，（3） （leave）a Chinese footprint on Mars for the first time.
The Chinese National Space Administration（CNSA） launched the Tianwen﹣1 mission to Mars in
July，2020，which carried a golf﹣cart﹣sized rover（漫游车） called Zhurong，a lander，and an orbiter to
Mars in an attempt（4） （explore） it.Today，it's reported that the rover has landed on the Red
Planet，which is an（5） （excite） for Chinese people.The Zhurong rover，which is named（6）an ancient fire god in Chinese mythology（神话），will begin a mission by first imaging and self﹣inspecting
（7） （it） parts before rolling out onto the alien planet.Once deployed（部署），the rover（8）
（expect） to spend around 90 days（around 93 Earth days）.Going into the details，the rover packs six
wheels and is（9） （rough） the size of NASA's twin Mars rovers Spirit and Opportunity.The
primary mission of the Zhurong rover is to study and understand the planet's composition and looks for signs of
water and ice.The rover is carrying scientific instruments（10） include two panoramic cameras，
ground﹣penetrating radar，and a magnetic field detector，all of which will help to study the climate and
weather on Mars.
passage 10
The Shenzhou﹣13 crew have （1） （safe） returned to Earth after their six﹣month orbital
trip，（2） nearly doubled the previous record of China's longest single﹣flight space mission of 92
days set by the Shenzhou﹣12.
At 9：06 am on April 16，the ground controlling team （3） （order） the return and the
return capsule separated with the Shenzhou﹣13 successfully.At 9：56 am，the Shenzhou﹣13 return capsule
touched down successfully in Gobi Desert.The Shenzhou﹣13 crew exited the return capsule one hour and 10
minutes after their touchdown，（4） （fast） than that for Shenzhou﹣12 crew which took one hour
and 40 minutes.Medical team confirmed that the crew Are （5） good health，marking the full
success of the Shenzhou﹣13 mission.
Shenzhou﹣13 mission commander Zhai Zhigang got out of return capsule first，reporting"feeling good".
（6） （follow） him，"Star﹣picking mom is home，"said Wang Yaping，the first spacewalking
Chinese woman.And Ye Guangfu soon joined them with good spirits.
（7） （ensure） their safe return，the taikonauts have been taking physical exercises to train
their muscles.Meanwhile，the ground support team has evaluated their physical and psychological condition
and made targeted （8） （adjust）.
Other than the two spacewalks，the crew has also played （9） significant part in many historic
moments in China in the past six months，sending their blessings during the Chinese New Year （10）
（moment）joining the audience of the Beijing 2022 Winter Olympic Games from space.
passage 11Chinese astronauts in Tangong space station opened a science lecture on December 9th，2021 as they
traveled around （1） Earth.
There （2） （be） a lecture and some interesting activities on that exciting day.First，Zhai
Zhigang，Wang Yaping and Ye Guangfu，all members of the Shenzhou XIII mission crew，greeted students，
teachers and other participants as the lecture began at 3：40 pm.They then showed viewers the place（3）
and worked.The astronauts carried out experiments to show interesting physical phenomena in space，（4）
（include） "disappearing buoyancy （浮力）"and a "water ball".At last，before the end of the livestreamed
activities，they（5） （happy） answered questions from students. （6） （million） of
primary and middle school students across China watched the 60 minute televised event，which was the first
lecture of the Tiangong Class，China's first extraterrestrial （地球大气圈外的） lecture series to make
students interested（7） space science.
The manned space agency said that more lectures would（8） （hold） based on the country's
manned spaceflights and would also be presented by some （9） （profession） Chinese
astronauts.Such activities are intended （10） （spread） knowledge about manned spaceflights for
science among young people.
passage 12
Chinese astronauts on December 9th，2021 beamed back a science lesson from the country's under﹣
construction space station.Students from five cities ，including Beijing and Hong Kong ，peppered the
astronauts with questions about living conditions in space and（1） （treat） to a virtual tour of the
station.The event was also open to the public through a livestream.
Wang Yaping，（2） only woman aboard the station，served as the main（3）
（instruct），while Ye Guangfu assisted and commander﹣in﹣chief Zhai Zhigang worked the camera.Wang
had taught a similar lesson while aboard one of China's earlier experimental stations in 2013.
The three arrived at the station in October，2021 for a six﹣month stay，（4） （charge）
mainly with preparing the main Tianhe module for the arrival of two（5） （addition） modules
named Mengtian and Wentian ahead of completion by the end of 2022.
Their Shenzhou﹣13 mission is China's（6） （long） since it first put a human in space in
2003，becoming only the third country to do so after Russia and the U.S.
The three are the second crew on the permanent station，（7） upon completion will weighabout 66 tons，much smaller than the International Space Station，which launched its first module in 1998 and
（8） （weigh） around 450 tons.
Along with installing equipment in preparation（9） the station's expansion，the crew is
assessing living conditions in the Tianhe module，（10） （perform） experiments in space
medicine and other areas.
passage 13
The first （1） （discover） of water on the moon was made in 2009 by India's Chandrayaan﹣
1 mission.The team used NASA's Moon Mineralogy Mapper instrument to （2） （final） discover
water.Since then，water has been mapped from orbit in （3） （mission） like NASA's Lunar
Reconnaissance Orbiter.
China's Chang'e5 lunar lander used its mineralogical spectrometer （矿物学光谱仪）， （4）
was designed to find water.It did so by （5） （determine） spectral reflectance （光谱反射率）
measurements of rocks on the moon.The water was found near the Oceanus Procellarum on the moon's near
side.
The Chang'e 5 landed on the moon on December 1，2020 with a mission to collect lunar rocks to bring
back to Earth.This is China's first ever sample （样本） return mission；however，the country has had four
（6） （success） robotic tasks to the moon before the Chang'e 5.
The lander was （7） the surface for less than 48 hours before it headed back into orbit around
the moon.
China is （8） third country to bring samples back from the moon，after the United States and
the Soviet Union.China is working hard to launch the Chang'e 6 in 2023.The lander is meant （9）
（be）a backup to the Chang'e 5，but it（10） （head） to the lunar south pole for samples.
passage 14
Obstacles for Female Scientists in Africa
Female scientists in Africa are entrepreneurial and resourceful.They （1） （seek） innovative
solutions to problems that affect their communities，and many are actively appealing to engage others in their
work.But for more women on the continent to achieve in science，they need policies that help to lower the
barriers to their success and that enhance international collaborations.Women in Africa experience greater barriers to developing careers in science，technology，engineering
and mathematics （STEM） than （2） in high﹣income countries do，with lack of funding a
particular problem.Africa's researchers badly need long﹣term，stable investment from internal and external
funding sources，including venture capital.In the latest poll，56% of respondents working in science in Africa
cited a lack of funding as their （3） （great）career challenge，and it was the top concern for both
men and women.If only Africa's governments and the international donor community （4） do more
to help scientists to realize their ambitions：even modest funding increases might go a long way （5）
accelerating nation﹣building.
Work–life balance is the second﹣most mentioned concern for women.It is clear （6） many of
the women have made huge personal sacrifices to obtain their PhDs — those who study overseas and are
mothers，for example，often spend months at a time away from their children， （7） （leave）
them in the care of others，such as fathers and grandparents.
Moreover，some women have not been promoted as quickly as their male counterparts， （8）
they are publishing at the same rate and bringing in as much research funding and equipment to their institutions
as men.The reasons vary，but include （9） （evaluate） according to outdated standard.
In that case，international collaboration needs to be more common in helping African women scientists.
（ 10 ） the COVID﹣19 pandemic has shown ， such exchanges can happen on virtual
platforms.Africa's female scientists are on the rise — and partnering with them could give sky﹣high returns.
passage 15
Video game developers （1） （use） artificial intelligence （AI） in new and interesting
ways ever since some of the very first video games were made.
For example，in the 1972 game Pong，your opponent would move a certain way （2）
（depend） on how you hit the ball.In 1978，the game Space Invaders introduced enemies that had different
movement patterns.And in the 80s，Pac﹣Man was the first video game with enemies that could search for you
based on the path you took.And those enemies were the first （3） （show） different
personalities.
Although these advancements were nothing more than simple algorithms （算法），they were classified
（4） AI because of the "intelligence'' they showed.They were programmed to act a certain way to
make their actions （5） （believe） and challenge players.And，as video games become （6） （increase） complicated，developers were trying to
find novel means to make the virtual worlds more immersive （沉浸式的）for players.For instance，many
modern games have characters and environments that change and respond to （7） a player acts in
the game.
Although this is a huge jump in video game （8） （develop）.Al in video games is advancing
in a way unlike ever before.But what exactly will the future look like for video games with （9）
（advance） AI systems？
"When you think about the first time you played your favorite game，you only get that experience
once.There's no way to copy that feeling." AI researcher and game developer Michael Cook said to the Verge，
"But automated game design lets you （10） （have） that experience many times over，because
this game can be constantly redesigning itself and refreshing itself，which is really cool."
passage 16
It is familiar to us Chinese that the year of 2023 is the Year of the Rabbit， （1） reminds us of
the "rabbit" on the moon，China's Yutu﹣2 lunar rover （月球车）.
The Yutu﹣2 is named （2） the pet rabbit of the Chinese moon goddess Chang'e.On January
3，2019，the rover was brought to the far side of the moon by China's Chang'e﹣4 lunar probe.It was the first
﹣ever soft landing on the（3） （previous） uncharted area of the lunar surface.
The Chang'e﹣4 lunar probe consists of a lander and the Yutu﹣2 rover.Before its launch，a relay satellite
（4） （send） into space in May 2018 to facilitate earth﹣moon communication.So far，the rover
has collected（5） （value） data on solar wind，soil，gel﹣like rocks and dead volcanoes.The data
and images sent back by the Yutu﹣2 have enhanced geography knowledge of the landing site， （6）
（deepen） understanding of the formation and evolution of the moon.
Of the many pictures of the lunar landscape（7） （take） by the Yutu﹣2，one square object
caused great debate among people on Earth.When the rover finally approached the object，it turned out to be
（8） rabbit﹣shaped rock.What an interesting coincidence!
The Yutu﹣2（9） （travel） more than 1，400 meters on the far side of the moon till now.It will
continue to uncover more（10） （mystery） of the moon.
passage 17China earlier on Thursday successfully launched Tianhe from the Wenchang Spacecraft Launch Site，
（1） （start） a series of key launch missions （2） aim to complete the construction of
the station by the end of next year.
The construction of the space station and a state﹣level space lab， （3） （be） key goal to
fulfilling the three strategic steps in China's manned space program and （4） important leading
project for building China's （5） （strong） in science，technology and aerospace.
China's most adventurous space attempt，the multimodule space station named Tiangong，will have three
main components — a core module （6） （attach） to two space laboratories — with a combined
weight of nearly 70 tons.The core capsule，named Tianhe，is 16.6 meters long （7） has a diameter
（直径） of 4.2 meters.The craft's weight is equal （8） the combined weight of 15 standard﹣size
automobiles.
The capsule will be（9） （centre） to the space station's future operations，given that
astronauts will live there and control the entire station from inside.It will （10） （use） to host
scientific and technological experiments too.The entire station is expected to become fully operational around
the end of 2022 and is set to work for about 15 years.
passage 18
Resources satellites mainly take on the jobs of observing the earth，including the land areas and the
oceans，and（1） （call） "photographers in space".With the multispectral （多光谱的） remote
sensors loaded on the satellites ， humans can not only survey resources but also forecast natural
disasters.Resources satellites can even see through the earth，exploring mineral resources and historical（2）
（site） that cannot be observed by our eyes.
China Center for Resources Satellite Data and Application（3） （be） the largest land observing
satellite data center in China.Located in Haidian district in Beijing，it operates and manages 19 satellites，
processing and distributing the satellite data.（4） monitoring natural resources and urban planning，
its another task is to use satellite images（5） （support） disaster relief.When a disaster happens，
the staff will immediately apply the satellites，obtaining clear images in（6） （respond） to the
disaster.So far，the center has obtained images of disasters including the floods in India ，the MH370
disappearance， （7） the forest fires in Australia.Such satellite images are offered to other countries
free of charge，thus（8） （provide） timely support for disaster assessment and relief.China's space industry has always been committed to enhancing human understanding of the earth，
（9） can better promote human development.One day，when we look up at the sky，we may find
that many satellites in （10） vast universe are looking back at us.
passage 19
ChatGPT is high﹣tech progress，not a revolution
ChatGPT is a powerful chatbot developed by OpenAI and launched in November 2022. （1）
（build） on top of OpenAI's GPT﹣3 family of large language models，it engages in human﹣like dialogue
egged by prompting.It （2） （design） to respond in a natural，intuitive way and has numerous
potential uses.
From a scientific point of view，there is a need to closely watch the development of such （3）
（technology） before reaching a conclusion about their efficacy and helpful nature.Technology progresses
step by step.So we should not panic thinking ChatGPT will take up jobs （4） till now needs humans
to fulfill.
ChatGPT is an example of high﹣tech progress，not a revolution.
First，ChatGTP （5） （make） quite some progress in natural language processing，yet it
still has a long way to go to completely understand the human mind and language faculty，because when it
comes to professional writing，ChatGPT at times writes plausible﹣sounding but （6） （correct）
or nonsensical answers.It might give some good answers to most of the general questions， （7） it
is no substitute for professional advice，such as medical prognosis and prescriptions，or legal advice.
Second，ChatGPT is still a product （8） very limited application.It has the potential to be used
for enhancing search engine functionality but，as a pre﹣trained language model，it will have limited use.
Due to these limitations，investors should not （9） （blind） invest huge amounts to further
develop ChatGPT and should not expect quick returns on investment.Yet as a （10） （promise） AI
development，ChatGPT is likely to advance in the medium，if not the short term.
passage 20
Will Robots Take Your Job in the Future？
In 2013，researchers at Oxford University did a study on the future of work.They concluded that almost one inevery two jobs have a high risk of （1） （automate） by machines.Machine learning is the
technology that's responsible for most of this situation.It's the most powerful branch of artificial intelligence.It
allows machines to learn from data and imitate some of the things （2） humans can do.
Machine learning started making its way into industry in the early 1990s.It started with relatively simple
tasks.It started with things （3） assessing credit risk from loan applications，sorting the mail by
reading handwritten characters from zip codes.Over the past few years，we （4） （make）
dramatic breakthroughs.Machine learning is now capable of far，far （5） （complex） tasks.In
2012，Kaggle challenged its community （6） （build） an algorithm （算法） that could grade
high﹣school essays.The winning algorithms were able to match the grades given by human teachers.
Now， （7） （give） the right data，machines are going to outperform humans at tasks like
this.A teacher （8） read 10，000 essays over a 40﹣year career.A machine can read millions of
essays within minutes.We have no chance of competing against machines on frequent，high﹣volume tasks.
But there are things we can do that machines can't do. （9） machines have made very little
progress is in dealing with novel situations.They can't handle things they haven't seen many times before.The
fundamental limitation of machine learning is that it needs to learn from large volumes of past data.Now，
humans don't.We have the ability to connect seemingly different threads to solve problems we've never seen
before.Machines cannot compete with us when it comes to dealing with novel situations，and this （10）
（put） a fundamental limit on the human tasks that machines will automate.
