（2022年·全国新高考II卷真题）We journalists live in a new age of storytelling, with many new
multimedia tools. Many young people don’t even realize it’s new. For them, it’s just normal.
This hit home for me as I was sitting with my 2-year-old grandson on a sofa over the Spring Festival holiday.
I had brought a children’s book to read. It had simple words and colorful pictures — a perfect match for his age.
Picture this: my grandson sitting on my lap as I hold the book in front so he can see the pictures. As I read, he
reaches out and pokes (戳) the page with his finger.
What’s up with that? He just likes the pictures, I thought. Then I turned the page and continued. He poked the
page even harder. I nearly dropped the book. I was confused: Is there something wrong with this kid?
Then I realized what was happening. He was actually a stranger to books. His father frequently amused the
boy with a tablet computer which was loaded with colorful pictures that come alive when you poke them. He
thought my storybook was like that.
Sorry, kid. This book is not part of your high-tech world. It’s an outdated, lifeless thing. An antique, like your
grandfather. Well, I may be old, but I’m not hopelessly challenged, digitally speaking. I edit video and produce
audio. I use mobile payment. I’ve even built websites.
There’s one notable gap in my new-media experience, however: I’ve spent little time in front of a camera,
since I have a face made for radio. But that didn’t stop China Daily from asking me last week to share a personal
story for a video project about the integration of Beijing, Tianjin and Hebei province.
Anyway, grandpa is now an internet star — two minutes of fame! I promise not to let it go to my head. But I
will make sure my 2-year-old grandson sees it on his tablet.

（2022年·全国高考甲卷真题）As Ginni Bazlinton reached Antarctica, she found herself greeted by a group
of little Gentoo penguins (企鹅) longing to say hello. These gentle, lovely gatekeepers welcomed her and kick-
started what was to be a trip Ginni would never forget.
Ever since her childhood, Ginni, now 71, has had a deep love for travel. Throughout her career (职业) as a
professional dancer, she toured in the UK, but always longed to explore further. When she retired from dancing and
her sons eventually flew the nest, she decided it was time to take the plunge.
After taking a degree at Chichester University in Related Arts, Ginni began to travel the world, eventually
getting work teaching English in Japan and Chile. And it was in Chile she discovered she could get last-minute
cheap deals on ships going to Antarctica from the islands off Tierra del Fuego, the southernmost tip of the South
American mainland. “I just decided I wanted to go,” she says. “I had no idea about what I’d find there and I wasn’t
nervous, I just wanted to do it. And I wanted to do it alone as I always prefer it that way.”
In March 2008, Ginni boarded a ship with 48 passengers she’d never met before, to begin the journey towards
Antarctica. “From seeing the wildlife to witnessing sunrises, the whole experience was amazing. Antarctica left an
impression on me that no other place has,” Ginni says. “I remember the first time I saw a humpback whale; it just
rose out of the water like some prehistoric creature and I thought it was smiling at us. You could still hear the
operatic sounds it was making underwater.”
The realization that this is a precious land, to be respected by humans, was one of the biggest things that hit
home to Ginni.
5．Which of the following best explains “take the plunge” underlined in paragraph 2?
A．Try challenging things. B．Take a degree.

（2022年·全国高考乙卷真题）The Government’s sugar tax on soft drinks has brought in half as much
money as Ministers first predicted it would generate, the first official data on the policy has shown.
First announced in April, 2016, the tax which applies to soft drinks containing more than 5g of sugar per
100ml, was introduced to help reduce childhood obesity (肥胖). It is believed that today’s children and teenagers
are consuming three times the recommended level of sugar, putting them at a higher risk of the disease.
Initially the sugar tax was expected to make £520m a year for the Treasury. However, data of the first six
months showed it would make less than half this amount. At present it is expected to generate £240m for the year
ending in April 2019, which will go to school sports.
It comes after more than half of soft drinks sold in shops have had their sugar levels cut by manufacturers (制
造商) so they can avoid paying the tax. Drinks now contain 45 million fewer kilos of sugar as a result of
manufacturers’ efforts to avoid the charge, according to Treasury figures. Since April drinks companies have been
forced to pay between 18p and 24p for every litre of sugary drink they produce or import, depending on the sugar
content.
However, some high sugar brands, like Classic Coca Cola, have accepted the sugar tax and are refusing to
change for fear of upsetting consumers. Fruit juices, milk-based drinks and most alcoholic drinks are free of the tax,
as are small companies manufacturing fewer than 1m litres per year.
Today’s figures, according to one government official, show the positive influence the sugar tax is having by
raising millions of pounds for sports facilities (设施) and healthier eating in schools. Helping the next generation to
have a healthy and active childhood is of great importance, and the industry is playing its part.
9．Why was the sugar tax introduced?
A．To collect money for schools. B．To improve the quality of drinks.
C．To protect children’s health. D．To encourage research in education.
10．How did some drinks companies respond to the sugar tax?
A．They turned to overseas markets. B．They raised the prices of their products.C．They cut down on their production. D．They reduced their products’ sugar content.
11．From which of the following is the sugar tax collected?
A．Most alcoholic drinks. B．Milk-based drinks. C．Fruit juices. D．Classic Coke.
12．What can be inferred about the adoption of the sugar tax policy?
A．It is a short-sighted decision. B．It is a success story.
C．It benefits manufacturers. D．It upsets customers.

（2023届吉林省吉林市普通高中高三毕业年级下学期第三次调研测试）Technology is developing by
leaps and bounds. A small device such as a smartphone now has more processing power than rockets to the Moon
once had. New tech brings many advantages, making our lives easier and opening up new opportunities. One piece
of kit that’s been really taking off recently is the drone. This pilotless mini aircraft, originally developed for aerial
(航空的) photography and warfare, is now bringing us benefits closer to home. In the last few years, tech
companies such as Amazon, Alphabet and Uber have promised us delivery drones—bringing goods to our
doorsteps in a matter of minutes. While progress in developing them has been slow, drones are becoming more and
more involved in our life.
Drones are helping to connect with and enhance the lives of people in remote locations. In the UK, the Royal
Mail wants a fleet of 500 drones to help deliver the mail to faraway communities. Windracers, the company
developing the drones, say they can fly in fog and produce 30% fewer emissions than comparable piloted aircraft.
And in Coventry in the UK, construction has started on an air center, which will act as a base for police and
delivery drones. Urban-Air Port Limited is working with car-maker Hyundai on the mini-airport, known as a
skyport.
Drones can also play a part in improving the health of millions of people. For example, an incredible
development project by the University of South Australia is for drones to eventually be able to survey populations
for disease by reading the blood oxygen levels of humans from the air. They’ll also be able to scan for other vital
signs, like coughing and a high temperature.
It seems that the sky is the limit for what drone technology can achieve. The only thing that sometimes keeps
it from working is regulation. Writing for the BBC, Jessica Brown says: “If our skies are to become as crowded as
our streets, airspace rules need updating to prevent accidents.”
1．What does the underlined sentence indicate?
A．A smartphone is more advanced than rockets. B．The rockets to the moon are very powerful.
C．Technology is progressing very rapidly. D．Technology is widely used in daily life.2．What do we know about drones according to the passage?
A．They were initially developed for bringing goods.
B．They’ve improved people’s life quality in remote areas.
C．They don’t cause any pollution to the environment.
D．They can diagnose and treat some diseases from the air.
3．What does Jessica Brown mean?
A．The development of drones is quite promising. B．It’s a pity that drones are limited to the sky.
C．Drones will be likely to cause some accidents. D．Some latest laws are needed to regulate drones.
4．Which is the most suitable title for the passage?
A．Drones Are Delivering Benefits Closer to Home B．Developing Drones Is Facing Many Challenges
C．Drones Are Currently Booming in Every Field D．Companies Are Competing to Develop Drones

（贵州省六校联盟2022--2023学年高三下学期适应性考试）In a video from Visit Iceland, a crew is seen
working on making a horse-sized keyboard out of massive blocks of wood. The keyboard is then put outside
against the gorgeous scenery for the typing horses to reply to emails. Unsurprisingly, the replies are nonsense, with
examples listed as “bpnisi. // hihaihf＝. sf”. “OutHorse Your Email” is Iceland’s latest stunt (噱头) to promote
tourism. Visitors can choose a trained horse to type responses to their work emails when they are on holiday.
Due to the pandemic, many workers have transitioned to remote working, finding that the lines between their
work and personal lives have become blurred. A survey conducted by Visit Iceland revealed that 59% of people
globally now feel as if their boss, colleagues, and customers expect them to reply when on holiday and 41% of
people check their work emails between one and four times a day when on holiday. That’s why Iceland is assigning
emails to its horses, asking them to make replies.
“When visitors travel to Iceland, we want them to fully experience everything our nation has to offer, from
breathtaking surroundings to endless landscapes," said the head of Visit Iceland. "Our OutHorse Your Email service
lets them do just that. With our world-first service, we hope to appeal to people to disconnect and take a well-
deserved, uninterrupted break.”
Since “OutHorse Your Email” service was launched, it has got a lot of attention from the Internet. “Is it a
ridiculous tourism stunt? Sure. But it indeed encourages me to enjoy my trip wholeheartedly,” said Thom Dunn, an
online user from Canada. Hunter Boyce from the USA also made a comment, “The service sounds interesting, but I
don’t want to drive my boss mad or be fired.”
5．What can we know about the typing horses?A．They are trained to reply to emails. B．They type meaningful emails.
C．They reply to emails in famous scenic spots. D．They work with a common keyboard.
6．What does the underlined word “blurred” in paragraph 2 probably mean?
A．Unclear. B．Unimportant. C．Controllable. D．Adjustable.
7．What’s the purpose of “OutHorse Your Email”?
A．To reduce people’s pressure. B．To fight against the pandemic.
C．To encourage undisturbed trips. D．To improve visitors’ work efficiency.
8．What’s Hunter Boyce’s attitude towards “OutHorse Your Email”?
A．Ambiguous. B．Negative. C．Favourable. D．Indifferent

（2023届山西省晋中市高三3月普通高等学校招生模拟考试）Travelling to watch their team play at the
World Cup took a little longer than usual for two French fans. Mehdi Balamissa and Gabriel Martin decided the
best way to travel from France to Qatar was on two wheels. The friends spent three months travelling 7,000
kilometers by bicycle to reach Qatar 2022 and watch their beloved France defend its title.
“It was a crazy idea, but we’re the kind of people that have big ideas and don’t want to have any regrets,”
Balamissa said, as both spoke to CNN Sport a day after arriving in the country. “So, since we are both self-
employed, we decided to block off three months of our time and come to Qatar.”
The pair started their mammoth (庞大的) journey at the Stade de France in Paris, home of the French national
team, and finished at the stunning Lusail Stadium, the venue that would host the final at Qatar 2022. They would
travel on average 115 kilometers per day, taking appropriate rest days when needed. They battled through the heat
of the desert in Saudi Arabia as well as flooded woodland areas in Hungary as they made their winding way to
Qatar, stopping off at campsites, lodges (乡间小舍) and hotels to sleep.
The idea came about after cycling from France to Italy to watch their country play in the UEFA Nations
League last year and they wanted to test themselves with a much longer trip. They hoped their trip would promote
the benefits of sustainable travel and said they planned to offer cycling workshops to children from disadvantaged
backgrounds when they eventually arrived home.
The two cyclists encountered many problems along the way, including dozens of flat tires, but relied on their
infectiously positive attitude to get them through. The pair laugh as they recall the time they had to travel 15 hours
to Riyadh, Saudi Arabia, in order to find a bike repair shop before travelling 15 hours back to the exact point where
they had stopped.
“We had many troubles, but we fixed them as we went,” Martin told CNN.9．Why did Balamissa and Martin go to Qatar?
A．To achieve their big ideas. B．To set them apart from the other fans.
C．To close off three months for no regrets. D．To watch their country defending its champion.
10．What does Paragraph 3 mainly tell us about the two fans?
A．Their travelling plan. B．Their severe challenges.
C．The schedule about their journey。 D．The scenery along their journey.
11．What’s the purpose of the two fans’ cycling trip?
A．To explore the secrets and laws of nature. B．To raise people’s awareness of eco-tourism.
C．To benefit more from the cycling workshops.D．To be involved in the UEFA Nations League.
12．What can we learn from Balamissa and Martin’s story?
A．Attitude is everything. B．Life lies in sports.
C．Life needs a slow pace. D．Man should be at one with nature.

（2023届安徽省合肥市高三第一次教学质量检测）Honeybees understand that “nothing” can be
“something” that has numerical meaning, showing that they have a primitive grasp of the concept of zero,
according to a newly-published study in Science.
Previous experiments have shown that honeybees have some facility for numbers, because they were able to
count landmarks (地标) as they searched around for a sweet reward. But in these tests, the insects couldn’t count
very high-only to about four. Still, that made researchers in Australia and France want to explore what else the bees
could do with numbers.
Scarlett Howard at RMIT University in Melbourne attracted bees to a wall where they were presented with
two square cards. Each card had a different number of black symbols, such as dots or triangles. Howard trained one
group of bees to understand that sugar water would always be located under the card with the least number of
symbols. “They could come and see two circles versus (与. . . 相对) three circles, or four triangles versus one
triangle,” she explains. The bees quickly learned to fly to the card with the fewest symbols,
But then they got another test, The researchers presented the bees with a card that had a single symbol and a
blank card that had nothing on it. The bees seemed to understand that “zero” was less than one, because they flew
toward the blank card more often than you’d expect if they were choosing at random. “When we showed them
zero-versus six, they did that at a much higher level than zero versus one,” Howard says. “So what tells us is that
they consider zero as an actual quantity along the number line.”
Aurore Avargues-Weber, a researcher with the University of Toulouse, points out even very young childrenhave trouble understanding that zero is a number. “It’s easy for them to count ‘one, two, three, four,’ but zero, it’s
not something to count,” she explains. What’s more, the brains of bees are incredibly tiny brains compared with the
brains of humans. Even so, the bees can understand the abstract concept of an empty set and she says she found that
very surprising.
13．What did the earlier studies find about bees?
A．They could fly higher than expected. B．They could understand some numbers.
C．They could remember a reward well. D．They could explore local landmarks.
14．What did bees learn to do in Howard’s first test?
A．Distinguish circles from triangles. B．Draw various symbols on the cards.
C．Identify the smaller of the two numbers. D．Locate sugar water with symbol shapes.
15．Why did bees fly to the blank card more frequently?
A．They were told the location of the reward. B．They chose to do it thoroughly by chance.
C．They preferred the card with nothing on it. D．They thought of zero as an actual number.
16．Why are young children mentioned in the last paragraph?
A．To argue that bees have a surprising memory. B．To show that bees’ gift for numbers is amazing.
C．To explain that bees learn as well as young children. D．To confirm that bees are smarter than young
children.

（河北省石家庄市部分重点高中2022-2023学年高三下学期3月月考英语试题）The first traffic lights in
the United States were installed because of an increase in traveller on the road in the 1920s. Worried about
accidents, towns and cities installed traffic towers to help the flow of cars. Officers manned the towers, using
whistles and red, green and yellow lights to indicate to drivers when they should stop and go.
Due to the absence of effective traffic signal systems on some streets, it caused risks at intersections. Then,
William Potts created the first tricolour, four-directional traffic signal. The very first four-directional traffic light
was installed at Woodward Avenue and Fort. But throughout the country, there were still a lot of systems for traffic
lights and patterns in place. Since this could end up causing more problems for drivers, the Federal Highway
Administration set uniform standards in 1935for all road signs, pavement markings and traffic signals, requiring
them to all use red, yellow and green light indicators.
Red is the colour with the longest wavelength; that means that as it travels through air molecules, it gets
diffused(扩散)less than other colour, so it can be seen from a greater distance. Yellow has a shorter wavelength thanred but a longer wavelength than green. This means that red is visible the furthest away, yellow in the middle and
green the least distance away—a helpful advanced warning for needing to slow or stop. But this could be a
coincidence. Red meaning stop originated with train warning lights, and it’s not clear whether that was chosen
based on wavelength, contrast against green nature or natural association of red with things like blood. It could be a
combination of all three!
Back in the 1900s, some stop signs were yellow because it was too hard to see a red sign in a poorly lit area.
Eventually, highly reflective materials were developed, and red stop signs were born. Since yellow can be seen well
at all times of the day, school zones, some traffic signs and school buses continue to be painted the colour.
17．What’s the purpose of installing traffic lights in the 1920s?
A．To increase the speed of cars. B．To improve road safety and efficiency.
C．To reduce traffic jams in towns and cities. D．To obey the standards of the government.
18．What does the underlined word“this”in Paragraph 2 refer to?
A．The first tricolour,four-directional traffic signal. B．The installation of the first traffic signal.
C．The existence of different traffic lights and patterns. D．The absence of traffic signal systems.
19．What’s the main idea of Paragraph 3?
A．The differences among the three colour. B．The wavelength of the three colour.
C．The reasons for choosing red as the stop signal. D．The relationship between red colour and its
wavelength.
20．Which may be a disadvantage of red as a stop sign?
A．It can’t be seen in the distance. B．It is a kind of highly reflective colour.
C．It is not suitable to be used in school zones. D．It can not be clearly seen in certain surroundings.
