1 . ①Have you ever seen a self-driving car? Have you ever wondered how an iPhone’s face recognition (人脸识别) works?
②All of these technologies have something in common: they use artificial intelligence (人工智能), or “AI”. AI is already all around us, and millions of people are using artificial intelligence every day. Even if you have used AI before, you might not know exactly how it works.
③ “AI” is defined as (被定义为) the ability for a computer to think and learn like people do. With AI, computers can finish tasks like people, including processing language, problem-solving, and learning.
④If you have ever watched a video on YouKu or DouYin, for example, you may have noticed that you will receive recommendations (推荐) for other videos based on (基于) what you already watched. That’s because of AI!
⑤Most people use search engines (搜索引擎) like Google and Baidu every day. Search engines use AI to rank (排名) websites in your search results to help you find the most useful websites for you.
⑥Even though AI is already used a lot today, computer scientists predict artificial intelligence will be even more popular in the future. Because of this, many jobs will also need us to understand how Al works so we can solve big problems.
1. Which of these is not an example of how AI is used today? ________.A.to help students talk to teachers | B.to recommend new videos to watch |
C.to open a cellphone with your face | D.to drive a car without a driver |
A.listening to a new language | B.understanding language |
C.speaking a language | D.reading a language |

A.① and ② | B.③ and ⑥ | C.⑤ and ⑥ | D.② and ⑤ |
2 . ①When the earth warms a little or a lot, people must make how they live and work different. For farmers, education (教育) can be really useful and helpful.
②In northern Kenya (肯尼亚), the weather was very hot. Mr. Lolok went to school when he was young. He now works as an accountants (会计)in the town. His elder brother Lokito never went to school. And he is a farmer all the time. Lolok sometimes helps Lokito keep cows.
③Lolok knew about the bad weather. So he told Lokito to sell half of his cows. That way, Lokito could keep the other cows healthy with the little water he had. However, Lokito wanted to keep all the cows for another year with the next rain. Then he could sell all the cows to make much money. In the end, there wasn’t any rain for half a year and half of the cows died (死亡).
④In eastern Kenya, the weather was also hot. Isaiah and his son Philip both grew corn (玉米). Isaiah’s corn was only 1 meter high but Philip’s was 2.5 meters high.
⑤Isaiah never went to school. “There is nothing we can do,” he says, “We just wish the God can give us a lucky rain.”
⑥Philip was a good student before. He bought new drought-resistant seeds (抗旱种子). He planted his seeds early before the first rain.Philip told his ways of farming to his father and the other villagers, but Isaiah and the others weren’t interested at all. Few of the villagers knew what was happening (发生).

3 . When you meet someone for the first time, what will you think of him or her? An American survey (调查) says that more than half of the people are in the good-looks club.
You may ask, “What is a good-looks club?” Well, people in this club always put appearance first. That is to say, what a person looks like makes people think of others differently. People’s looks may affect (影响) their jobs.
An Internet survey asks 2, 000 young people about it. 30% of them say they can tell about someone’s work only by his or her clothes. 10% of them say they often leave in the middle of the date (约会) because the people’s looks are not what they want. 50% of them say they will choose the one with good looks to be a new friend when they come to a new place. 80% of them believe that it is hard for the good-looking ones to live happily with the not-so-good ones.
Parents and teachers always teach us not to know about people by their looks, but sometimes the first impression (印象) is very important. It can tell people your age and your job. Your habit is also in it. We can often learn about someone from what he wears and what he says. So we must learn to wear right clothes at different time and places.
Our appearance can help us open the door of what other people may think of us. However, when we finally get to know someone well, ________ That is to say, how we do things and our personalities (性格) are still the most important things that can help other people know us better.

①In your last letter you said that you wanted to make more friends and be a better person in high school. Here are some tips that can help you become such a person with a good character (品质).
②First, people with good characters do not cheat or lie. They always tell the truth and keep their promises. For example, if a teen promises to go home on time and he keeps his words, his parents will trust him more next time.
③Second, being responsible (有责任心的) means being willing (乐意的) to take on duties or tasks (任务). It also means being willing to accept the mistakes you have made. A responsible person accepts the results of his or her actions and decisions, whether they are good or bad.
④Third, everyone has his or her own ideas. Learning how to listen to others’ ideas instead of trying to make them accept yours. Be kind to others like the way you expect others to treat you. Keep smiling while talking with others.
⑤Finally, caring means treating others with understanding. So, try to help others when you can, ▲ Make an effort (努力) to welcome new students in your school. Listen to your friend when he or she needs you.
⑥A good character is not something that you feel or show once in a while. It is part of who you are. By having a good character, you will feel good about yourself and make responsible decisions.
⑦I really hope these tips can help you become a better person. Looking forward to your reply.
Yours,
Lily

5 . Shenzhou XVI spaceship (神舟十六号载人飞船) successfully reached space on May 30th. There are three people on it: Jing Haipeng, Zhu Yangzhu and Gui Haichao.
They are special in many ways. Jing is now the most experienced astronaut in China. This is the fourth time for him to fly into space. Gui is a scientist. He is also the first Chinese civilian (平民) to make it.
Both Zhu and Gui are China’s third-generation (第三代) astronauts. At that time, one woman and 17 men were picked. And they are in three groups. One group “fly” the spaceship. Another group is “fix” the spaceship. There is also a group of scientists, such as Gui. They do scientific studies in space.
Gui’s glasses also draw people’s attention because astronauts aren’t usually nearsighted. But it’s safe to wear glasses in the space station. However, during the launch (发射) and return, Gui needs to take off the glasses.

6 . Western people see the rabbit (兔子) as a sign of good luck. They believe a rabbit’s foot can bring good luck to its holder. This may go back to an old tradition. If teenage hunters (猎人) caught a rabbit, they could get the animal’s hind foot (后腿). It also welcomed them to manhood (成年).
Rabbits also show up in other areas of Western culture. In the book Alice in Wonderland, Alice follows a rabbit to get away from her world and start her adventure (冒险). There is the Easter Bunny, too. Rabbits are close to the idea of new life because they have lots of babies. The night before Easter, kids often make nests (窝) in their gardens for the Easter Bunny.

8 . There’s a new AI bot (自动程序): Chat GPT, and you’d better pay attention, even if you aren’t into artificial intelligence (人工智能) The tool is an AI chatbot system that Open AI made it public in November 2022 to show off and test what a very large and strong AI system can do.
Chat GPT remembers your conversation, using last questions and answers to make its next answers. It makes its answers from plenty of information on the Internet. Chat GPT is built on top of the Open AI GPT-3 family of large language models.
You can ask Chat GPT anything, like explaining physics, asking for birthday party ideas and getting programming help. Perhaps it’s not smart enough to take the place of all humans yet, but it can be creative, and its answers can sound right. A few days after its launch (发布), more than 1 million people were trying out Chat GPT. UBS worker Lloyd Walmsley estimated in February 2023 that Chat GPT reached 100 million monthly users in January.
Chat GPT is free to use at the moment because it is still in its research period. But when too many people use the server, it overloads and can’t give your answer. It just means you should try visiting the site at a later time when fewer people are trying to use it. If you want to skip (跳过) the wait and enter the site quickly, there is a choice for you. As of Feb. 1, 2023, Open AI has a Chat GPT pro plan, Chat GPT Plus, which allows users to have priority access (优先进入) even when lots of people are using it. This service does come at a cost of $20/month.
However, Chat GPT cannot replace Google. Chat GPT is an artificial intelligence bot that provides solutions to your questions, but Google is a search engine in which you can search for as much information as possible. Chat GPT has limited (有限的) knowledge because of its programming but Google has unlimited knowledge which adds the most recent news every day.
1. What does paragraph 2 mainly tell us about Chat GPT?A.It mainly tells us its language model. |
B.It mainly tells us how it works. |
C.It mainly tells us its design background. |
D.It mainly tells us its latest development. |
A.It guides users to experience free services and get the best answers. |
B.It allows net surfers to skip advertisements which takes a few second. |
C.It can help workers check the failure of the system in a quick way. |
D.People who paid $20/month can use the Chat GPT without waiting. |
A.覆盖 | B.影响 | C.代替 | D.超过 |
A.the answers given by Chat GPT are right all the time. |
B.Chat GPT cannot take the place of Google. |
C.there is no need for people to pay for the Chat GPT. |
D.if you want to get the latest information , Google is a better choice. |
9 . ①Would you like to get fewer colds and feel better? Would you like to have a taste of a special plant? Would you like to keep a plant with little care? An Aloe Vera (芦荟) plant could be just what the scientists may suggest!
② ▲ Studies have shown that they give off oxygen (氧气) and take away bad things from the air. With clean and fresh air, you are more likely to stay away from colds, sore throats and dry coughs. And even if you do get sick, Aloe Vera plants may help you get better from the illness faster.
③Did you know that Aloe Vera plants can be used as medicine? Aloe Vera gel (胶体) helps to deal with the pain of burns. And it also helps with itchiness (痒) caused by insect bites. To get this gel, just cut off a part of the plant, peel it, and put the gel on the affected skin (患处). This easy-to-get and safe-to-use medicine is available to you all year round.
④Besides medical use, Aloe Vera plants are also popular in food industry. Whether you are interested in Aloe juice or crazy about Aloe yogurt, you’ll easily find them in the supermarket. Aloe Vera can also go with other vegetables to make a safe dish on your dinner table.
⑤Aloe Vera plants are very easy to take care of. They like dry, warm air with bright light, so they grow best when placed near a window. Aloe Vera plants are able to keep water in their leaves. So, they do not need to be watered so often as most houseplants. Just wait until the earth is completely dry before you water them. When watering, make sure the earth is wet enough so that it can last for a long time. That’s all you need to do to take care of an Aloe Vera plant. Isn’t it the perfect plant for lazy and forgetful gardeners?

10 . Are children smarter than adults? The answer is “yes” when it comes to learning new things. A new study shows that kids pick up new knowledge and skills faster than adults.
The study was carried out by scientists from the U.S.A. and Germany. In the study, some kids (from 8 to 11) and adults (from 18 to 35) learned the same lessons of new information and skills. The scientists looked at their GABA (γ-氨基丁酸) levels before, during and after these lessons. GABA is a chemical (化学物质) that our brain produce. It helps us remember newly learned information.
According to the study, the GABA levels in the children’s brains increased (增加) quickly during the lessons. This increase lasted for several minutes after the lessons were over. In the adults, however, there was no change in their GABA levels during or after the lessons.
This study encourage people to give children more chances to learn new skills. ▲ “We might develop a new technology, for example, to increase the amount of GABA in the adult brain,” said one of the scientists.
