For example, if you wanted to teach a computer to know different types of fruits, you would give it a lot of pictures of fruits and tell it which ones are apples, bananas, and so on. The computer would then use this information to find out what new fruits are. This process is called “machine learning”. What can AI be used for? AI is already being used in many different areas. For example, AI can be used to: ● diagnose and treat diseases; ● drive self-driving cars; ● recommend movies and TV shows according to your viewing history; ● help teachers give marks to papers. The Future of AI In the future, AI may completely change many parts of our lives and help us solve some of the world’s biggest problems. However, it’s also important to remember that AI is just a tool, and it’s up to us to decide how we use it. With responsible and ethical (合乎道德的) use, AI can make the world a better place for everyone! PS: The copy above is created by AI ! ( )1. Which of the following can be put in ▲ ? A. When was AI invented? B. How does AI work? C. Why is AI important? D. Who uses AI the most? ( )2. What does the underlined word “diagnose” probably mean? A. Spread. B. Cause. C. Recognize. D. Make. ( )V3. How does AI recommend movies and TV shows? A. By guessing freely. B. By using your viewing history. C. By asking your friends. D. By creating new movies. ( )4. What can we learn from the passage? A. AI isn’t a tool and it can decide how people use it. B. AI can make a better world if we use it correctly. C. It’s impossible for AI to solve the biggest questions. D. AI can not help teachers to mark the papers. ( )5. Who wrote the passage? A. A worker. B. An engineer. C. A writer. D. AI. 任务三 阅读理解B(20分) ① What are you holding in your hand while you are taking the exam? Right. A pen. ② The history of the pen is very long. A long time ago, people used sharp stones to make marks on things. Then, the ancient Egyptians made reed (芦苇) pens. They cut reeds and used them to write. Later, in China, people invented the writing brush. It feels soft and can write beautiful characters. In the Middle Ages in Europe, it was popular to use feathers (羽毛) of birds to write. And now, we have all kinds of pens like ballpoint pens (圆珠笔) and gel pens (中性笔). They are very convenient. ③ Pens are widely used in many ways. Students use pens to do homework and take notes in class. Scientists use pens to record experiment results. Artists use special pens to draw pictures. Pens help us record knowledge and history. Because of pens, we can read many great works from different times. Pens also let us show our creativity. We can write our own thoughts and feelings. And when we write with a pen, it makes us think more. ④ In the future, pens will be more amazing. With the development of science and technology, pens might have built-in cameras to record what we write and draw. Maybe they can change colours according to our feelings and correct our spelling mistakes right away. They will also connect to the Internet, helping search for information while we are writing. What’s more, they will be made of new materials that are environmentally friendly. ⑤ Pens are not just simple tools. They are the most powerful instrument which we own.

However, the problem is that there are only about 200 guide dogs in China. Then what can help fix the situation? A smart harness (智能背带) called Biped can do the job. 3. _________. The harness uses the same technology that allows self-driving cars to drive around obstacles (障碍物). Most obstacles are silent but dangerous. The harness can warn blind people to avoid obstacles with 3D sounds. And the closer the user gets to obstacles, 4. _________. The harness can also give directions through GPS. As a result, Biped can help the blind move around more easily and independently. Thanks to Biped, the life of the blind is becoming easier . 5. _________. A.

AI brings both benefits and challenges. It improves efficiency in tasks like data analysis, but may reduce human employment opportunities. Personally, I use AI for homework research and language learning. It helps me understand complex concepts quickly. However, I hope future AI development will focus more on assisting humans rather than replacing us. Ethical guidelines should be established to ensure AI serves humanity positively. Looking ahead, I’m excited about AI’s potential in education and healthcare where it can make knowledge more accessible and improve the medical diagnosis. Yours, Student Wang 1 学科网（北京）股份有限公司 $
