Artificial Intelligence, or AI, is a field of computer science that focuses on creating machines that can think and learn like humans. AI has become one of the most important technologies of the 21st century. It is used in many areas of our daily lives, from smartphones to self-driving cars. AI systems can perform tasks that normally require human intelligence. These tasks include recognizing speech, understanding language, solving problems, and making decisions. For example, when you ask a virtual assistant like Siri a question, AI helps it understand and respond to you. When you use a navigation app, AI calculates the best route for you. There are two main types of AI: narrow AI and general AI. Narrow AI is designed to do one specific task. Most of the AI we use today is narrow AI. General AI, on the other hand, can perform any intellectual task that a human can do. General AI does not yet exist, but many scientists are working on it. The development of AI has brought many benefits, but it also raises concerns. Some people worry that AI will take away jobs from humans. Others are concerned about privacy and security. Despite these challenges, AI will continue to grow and change our world. ( )1. What is AI? A. A type of robot. B. A field of computer science. C. A programming language. D. A new smartphone. ( )2. What can AI do? A. It can only play games. B. It can do tasks that require human intelligence. C. It can replace humans completely. D. It can only understand speech. ( )3. What is narrow AI? A. AI that can do any task. B. AI that is designed for one specific task. C. AI that is very powerful. D. AI that can think like humans. ( )4. What is one concern about AI mentioned in the passage? A. AI is too expensive. B. AI will take away jobs from humans. C. AI is not useful. D. AI is not safe to use. ( )5. What is the main idea of the passage? A. AI is only used in smartphones. B. AI is a technology that can think and learn like humans. C. General AI already exists. D. AI will not change our lives. B   My Experience with Hello Dish Last Sunday, my parents were both busy with work. I was home alone and feeling a bit hungry. I decided to try cooking by myself. I had seen my mom use an app called Hello Dish many times. It is a cooking app that provides step-by-step instructions for making dishes. I opened the app and chose a simple dish — tomato and egg stir-fry. The app showed me a list of ingredients and the cooking steps. I followed the instructions carefully. It told me how much oil to use, when to add the tomatoes, and how long to cook the eggs. Everything went smoothly. In about 20 minutes, the dish was ready. When my parents came home, they were surprised to see the food on the table. They tasted it and said it was delicious. They were very proud of me. I felt happy and confident. I realized that cooking was not as difficult as I thought, especially with the help of technology. Since then, I have been using Hello Dish to try more recipes. I have learned to make several different dishes. Technology has truly made my life easier and more interesting. ( )6. Why did the writer decide to cook by himself? A.

Tired and disappointed. B. Happy and confident. C. Angry and upset. D. Bored and uninterested. C   The Relationship Between Science, Engineering, and Technology Science, engineering, and technology are three very closely connected fields. However, they are not the same. Understanding the differences between them can help us better understand how they work together to improve our lives. Science is the study of the natural world. Scientists ask questions about how things work and try to find answers through experiments and observations. Science is about understanding the world as it is. Engineering, on the other hand, is about creating new things. Engineers use scientific knowledge to design and build solutions to problems. They create the world that has never been. Technology is the use of scientific knowledge to achieve engineering goals. It includes tools, machines, and systems that we use in our daily lives. For example, the smartphone is a technology that uses scientific knowledge in engineering. Technology helps us solve problems and make our lives more convenient. These three fields are closely connected. Scientific discoveries often lead to new technologies. Engineering turns those technologies into practical applications. Without science, engineering would not have the knowledge it needs. Without engineering, technology would not exist. They work together to make progress possible. ( )11. What is the main idea of the passage? A. Science is more important than engineering. B. Science, engineering, and technology are different but closely connected. C. Technology is the most important of the three. D. Engineering is the same as technology. ( )12. What does science study? A. The future world. B. The natural world. C. Technological tools. D. Engineering goals. ( )13. What does engineering do? A. It studies the world as it is. B. It creates new things. C. It uses technology. D. It asks questions. ( )14. What is technology? A. The study of the natural world. B. The use of scientific knowledge to achieve engineering goals. C. The creation of new things. D. The design of buildings. ( )15. What does the passage say about scientific discoveries? A. They are not important. B. They often lead to new technologies. C. They are the same as engineering. D. They only happen in the past. 八、完形填空（阅读下面的短文，从每题所给的A、B、C、D四个选项中选出最佳选项） Yining's parents were still at work, so she decided to make dinner by (1) ______.
