1 . “Welcome to our new ‘classroom’!” said Chen Dong, one of the three astronauts of the Shenzhou XIV mission.
They were giving a science class 400 kilometers above Earth on October 12. It was the third space class from the Tiangong Space Station, but the first one from the Wentian lab module (实验舱) since its launch in July. The former two classes were held in the Tianhe core module (核心舱).
What does the new “classroom” look like? Chen, together with Liu Yang and Cai Xuzhe, showed us around. “The beds in the Tianhe module are placed horizontally (横着), while our beds are kept upright,” said Liu. That means astronauts in the Wentian lab module need to sleep standing up! But as Liu explained, people don’t feel any difference because there’s no gravity (重力) in space. Astronauts can even sleep on the ceiling or upside down!
The astronauts also showed their “space farm”, where lettuce, wheat, thale cress (拟南芥) and rice are grown. “Take a picture!” “Send the picture!” Through a voice-controlled camera, Chen already sent a picture of the thale cress to scientists on Earth. Then he used scissors to cut a sample (样本). “I’ll put it into a fridge at-80℃and later give it lo scientists on Earth,” said Chen. Scientists will study how the environment of space affects the growth of plants.
“Can you see the water drops coming from the leaves? This is called ‘guttation’ (植物吐水现象).” said Liu, holding the well-grown rice. In space, the water drops are much bigger than those on Earth. So people can clearly see the guttation.
“We hope in the near future, we can harvest the food grown on our own,” said Chen. “Maybe one day, we can harvest food on the other planets like the moon or even Mars!”

2 . Imagine a tiny robot crawling through your body, helping doctors with their work. It’s not from a science novel. Doctors are now using robots to do operations (手术). This is because robots can do some work that doctors can’t. The robots carry small cameras, which allow doctors to look inside patients’ bodies. The robots also have tiny scissors and other tools. “It’s like having little hands inside the patients,” said Dr. Wang from a hospital in Beijing.
Here’s how they work: The doctor makes a small cut in a patient. Then, the doctor puts the robot through the cut. Next, the doctor controls the robot to reach where it needs to go. Finally, with the help of the robot, the doctor looks inside the patient’s body and begins to work.
The robots have many advantages for doctors and patients. They help cut medical costs and make difficult operations quicker and easier. They allow doctors to operate with less damage (伤害) to patients’ bodies, too. This helps them to heal faster.
However, the robots aren’t perfect. They can be expensive. What’s more, they are just tools to help humans, and they must be used by skilled doctors. Even the best robots can’t do everything that humans can do.
Scientists are working to make robots smarter. Someday, robots may do even more than expected for humans.

3 . Today almost everyone knows computers and the Internet. If I ask you “What is the most important in your life?”, maybe you will say “Computers and the Internet.”
The first computer was made in 1946. It was very big but it worked slowly. Today computers are getting smaller and smaller. But they work faster and faster. What can computers do? A writer has said. “People can’t live without computers today.”
The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, write letters, do shopping, play games or make friends.
Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don’t know their real names, ages, and even sex. They are so interested in making the “unreal friends” that they can’t put their hearts into study. Many of them can’t catch up with others on many subjects because of that.
We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet.

4 . You scan a QR code(扫二维码) to order a meal, but it asks for your phone number. You book a taxi online, and you need to fill in your address. You go back home and are asked to show the camera your face. Data collection is everywhere.
However, companies can use the personal information they collect for marketing or telecommunication fraud(电信诈骗). Researchers did a survey of 5,458 people on personal information leak(泄露) in 2021. About 85 percent of people said they had experienced leaks from their smartphones. Most said they got unwanted calls or text messages.
To deal with such problems, on Nov. 1, 2021, the Personal Information Protection Law came into effect in China. It is the first law on personal data protection. The law says that a person’s name, date of birth, ID number, address and phone number are all personal information. The information can be in electronic or other forms. Some kinds of personal information are regarded as “sensitive”(敏感的). They include fingerprints, faces, medical health, financial accounts(金融账户) and so on.
According to the law, collecting, using and keeping personal information will be strictly managed. One key rule is that users should know and agree with giving away their personal information. The rules are even stricter for sensitive information. For example, if companies want the personal information of a teenager, the parents need to know and say yes first.
1. The survey mentioned in paragraph 2 shows that ________.| A．people don’t mind information leakage | B．telecommunication fraud is increasing |
| C．personal information is easy to collect | D．information leakage is quite common |
| A．An ID card. | B．A postcard. | C．An email address. | D．A letter. |
| A．生效 | B．活动 | C．禁止 | D．影响 |
| A．Companies are not allowed to collect users’ information. |
| B．Kids cannot tell other people their parents’ information. |
| C．People cannot give it away without the agreement of their family. |
| D．It can only be given away with users’ agreement. |
5 . The Chinese kite is a symbol of the Chinese art. Flying a kite is a very popular activity in China. In spring, large numbers of people gather in the squares or parks and fly beautiful kites there.
A philosopher (哲学家) called Mozi was said to be the inventor of the Chinese kite. His kite had the bird’s name of “Yuan”, a kind of bird with a long tail. He made the kite out of wood. Later, his student Lu Ban improved it and made the kite out of bamboo.
With the development of paper-making, paper was introduced into the kite-making. The kite got the name “Zhi Yuan”, as “Zhi” in Chinese means paper. And during the Five Dynasties period, people tied the bamboo whistle (哨子) to the kite. When the kite was flying, the air could make the whistle sound like Guzheng playing. So the kite carried the name “Fengzheng”.
From then on, making and flying the kite became very popular in Weifang, Shandong Province. Every year in spring, when the weather became warm, almost every family went out to fly the kite and have a picnic on sunny and windy days. It was an exciting folk activity and a good time to show different beautiful kites. At the same time, they also enjoyed the warm weather and fresh air. The tradition has been well kept until today and has become the world-famous Weifang International Kite Festival, which is held from 20th to 25th in April every year.
Flying a kite in spring does people much good. For example, it is a good way to reduce the backache. Besides, when people fly a kite, it can help people forget their stress and connect them to nature.

Many people just regard crows (乌鸦) as a natural cleaner. But researchers have found more than that. Here is something about crows that you might not know.
Crows have strong family values. They are social, living in large families of more than ten birds. When you see a number of crows gathering, they’re usually family groups that are helping each other. Crows take care of their kids, just like people.
Communication is key to their survival (生存). Many calls are used, each carrying a different message. For example, they have separate warning calls for cats, birds and people. Loud “caws” are their common calls, but they also use other calls. Some crows even imitate (模仿) the sounds of other living things.
Marzluff, a scientist who studies wildlife science, did several experiments to decide whether wild crows remember human faces. In one researchers wearing masks (面具) caught seven crows and marked them. After setting the crows free, researchers found that ordinary passersby got no reaction, but as soon as anyone wearing the same mask passed by, they made loud warning calls even years later.
Catherine Shevcenko of Diva Crows, a wildlife protection organization, warns, “Never do bad things to a crow. They not only remember faces but teach their baby crows to be careful.”
They also remember those who were kind to them and pass that information along, too, often bringing gifts of rocks or other small objects as thanks . So you see they are so smart, family-loving and grateful that you may want to know them a lot.
1. We can know crows are social and look after their kids just like2. Crows can use different calls to
3. Marzluff found crows can remember
4. The crows use some small gifts to show
5. From the article we know that crows are so thankful,
7 . Mark began to introduce the guest speaker to the listeners, but then stopped for a while. He had forgotten her name.
Barbara hid her valuable things when she went on vacation. When she came back, she couldn’t remember where she’d put them.
Perhaps you’ve had such experiences like these. Many people have. But they haven’t realized that they have a memory problem. Neither do they know a simple but important fact: Memory can be improved. If you just accept that, the following will show you how.
First, relax. If you are over worried about something, you’ll forget it. If you keep telling yourself that your memory is bad, your mind will come to believe it and you won’t remember things. When you forget something, don’t follow up with saying like “Oh, my god! I always forget things!” Such words will have a bad result on you and your memory.
But relaxing isn’t enough. To improve your memory, you’ll need to take an active role. Like your body, your memory can be made strong through exercise. Look for opportunities to exercise your memory. For example, if you’re learning a language, try to actively remember a lot of new words.
If you don’t notice things actively, you won’t remember them. So, you can make pictures of what you see in your mind every day. For example, don’t just put your keys down! If you want to find them again, make a mind picture of the place where you’re putting them.
1. The first two paragraphs just tell us ________.| A．language problems of two persons | B．Barbara was a very rich person |
| C．examples of memory problems | D．Mark often forgot his friends’ names |
| A．places | B．doctors | C．chances | D．projects |
| A．doing sports every day | B．making mind pictures of what you see |
| C．realizing your memory problems | D．talking to your friends |
| A．introduce the guest | B．forget unhappy things |
| C．remember new words | D．improve your memory |
8 . You like rats? You must be kidding. Everyone hates rats. But rats may soon be man’s new good friend.
What happens after an earthquake? We send in rescue（营救，救援） dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. “Robots’ noses don’t work well when there are other smells around. Rats are good at that Rats can also see in the dark, they are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!”
The “rat project” is not finished, but a scientist says, “It would be great. A rat could get into spaces we couldn’t get to, and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).

9 . We each have a memory. That’s why we can still remember things after a long time. Some people have very good memories and they can easily learn many things by heart, but some people can only remember things when they say or do them again and again. Many of the great men of the world have got surprising memories.
A good memory is a great help in learning a language .Everybody learns his mother language when he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are living with their parents in foreign countries. They can learn two languages as easily as one because they hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language because the students have so little time for it, and they are busy with other subjects, too.
But your memory will become better and better when you do more and more exercises.
