All you need is a computer and a headset（头戴式耳机）. Here are some opinions about online classes from three students. Li Lan is a 15-year-old student from Beijing. “There are no real teachers watching me. I can surf the internet or do other things if I want to. It’s hard to always listen to them carefully all the time,” she says. Li Lan tries to prepare a lot before class to make sure she will pay attention. She also tries to talk more with teachers online. But she still finds it difficult to stay focused. Li Wen is a 14-year-old student from Chengdu. She thinks online interaction (互动) isn’t enough. “The online teachers don’t really get to know me. And I don’t know them well either. If I don’t hand in homework, all I get is a short message instead of real concern,” she says. Wang Qiang, 16 years old, comes from Shanghai. “It saves time and money compared to taking offline classes. Also, if I don’t understand some parts of a lesson, I can watch that part of the lesson again,” he says. 根据材料内容选择最佳答案。 41. What do you need to prepare before online classes according to the text? ① ② ③ ④ A. ①② B. ②③ C. ③④ D. ②④ 42. How old is Li Lan? A. Thirteen. B. Fourteen. C. Fifteen. D. Sixteen. 43. According to Li Wen, if you don’t hand in homework, what will you get? A. A real teacher. B. An interaction. C. A real concern. D.A short message. 44. What is Wang Qiang’s attitude toward online classes? A. Negative. B . Positive. C. Unclear. D. Worried. 45. In which part of a newspaper can we read the text? A. Family. B. Money. C. Sport. D. Internet. B "You really need to stop watching videos on your screen all the time，Li Ming，"said Li Tao. "But the video is so fun that I can't take my eyes off it." "I will tell you a true story about myself，then you will know the importance of avoiding looking at your phone all the time，"said Li Tao. "Last Monday，I walked home from school，with my eyes glued to the screen of my phone. Because I didn't look up，I failed to see the open manhole（窖井）right in front of me. Suddenly，I stepped into it and fell down into the sewer（下水道）.I was scared and tried to climb out，but failed. Just then，I heard a voice from above，"Hey，are you okay down there？'It was an old cleaner. She helped me call the police right away. Soon，two policemen came with a long ladder（梯子）.They put it down into the sewer. I held it and climbed up. I stood on the road，dirty all over. But luckily，I was safe. And I realized how often I walked while glued to my phone. Phones are useful，but that day，I learned that we need to put them away sometimes.” After hearing the story，Li Ming was lost in thought. 51. When did the accident happen to Li Tao? A. Last Sunday. B. Last Monday. C. This Friday. D. Yesterday. 52. How did Li Tao stop Li Ming from looking at his phone all the time? A. By shouting at him. B. By taking away his phone. C. By playing games with him. D.

He may ask cleaners for help when getting into trouble. C What kinds of things do you usually do on your phone？Are these activities the same as what people did in the past？In fact，phone functions（功能）have changed a lot over time. The first mobile phone appeared in 1973.It was big and heavy，so people called it" the brick（砖块）”.It could only be used for making calls，and its battery（电池）only lasted about half an hour. In the 1990s，mobile phones became smaller and lighter. They had new functions. For example，they could be used to send short messages，not just for making calls. Although some people started using them，they were still expensive. By the 2000s，phones had become even thinner and smarter. They had cameras and could play music. People started to take photos and listen to songs on their phones. Then，the first smartphone came out. It had a touch screen and could connect to the internet. Today，smartphones have already become a part of everyday life. We use them to chat，study，shop，and even pay for things. From "the brick" to smart devices（设备），mobile phones keep getting smarter and making our life easier. 56. How does the writer lead into the topic ? A. By listing numbers. B. By asking questions. C. By making a comparison. D. By showing facts. 57. When did the first mobile phone appear? A. In the 1930s. B. In the 1970s. C. In the 1990s. D. In the 2000s. 58. What kinds of new functions did mobile phones get in the 1990s? A. Taking photos. B. Sending short messages. C. Connecting to the internet. D. Playing music. 59. In what way does the writer develop the text? A. In time order. B. In space order. C. In event order. D. In cause-result order. 60. What can we know from the text? A. The battery of the first mobile phone could only last for an hour. B. Mobile phones in the 1990s were very cheap. C. The early smartphones had a touch screen. D. Mobile phones will become more important than computers. D With the development of internet technology，many modern technologies have appeared and changed our lives. AI is one of them，and its influence（影响）will be even greater in the future. In health care，AI will play an important role. For example，it can analyze（分析）a patient's medical history much faster than humans. This will help doctors provide more appropriate medical services. AI will also have a bigger influence on education. For example，it can support students when they have problems in their studies after school. Besides these advantages，AI may also bring some challenges. One of the most serious problems is job loss. As Al becomes more powerful，it can replace（代替）people in many jobs. Some factory workers and taxi drivers，for example，might lose their jobs because robots can do their work much better and without breaks. In short，as internet technology continues to influence the world greatly，AI is sure to bring even greater changes to our future. When we enjoy its benefits，we also need to deal with the problems it may cause. Only then can everyone truly benefit from it... 61. What does the underlined word " appropriate " in Paragraph 2 mean? A. different B. correct C. simple D. new 62. How many good influences will AI have on us according to the text? A. 1. B. 2. C. 3. D. 4. 63. What's the main idea of Paragraph 3? A. AI will develop quickly. B. AI will have many advantages. C. AI will bring some problems to us. D. We should try to enjoy the benefits of AI. 64. What will the writer go on talking about in the following paragraphs? A. How AI technology helps us in other ways. B. How people deal with the problems AI technology causes. C. What bad influences AI technology has. D. What AI's future is like. 65. What is the structure of the text? A. B. C. D. 第二节 阅读下面短文，从短文后所给的五个选项中选出能填入短文空白处的最佳选项，使短文通顺、连贯，意思完整。（共5 小题；每小题1分，满分5分） The internet is a wonderful tool.

Usually, a teenager hides his diary and treats it as something full of 83 (secret). A blog has both good and bad points. The biggest problem is that anyone can 84 (read) your blog. If you are 85 (happy) with a friend and write something bad about him in your diary, he may never know. However, 86 you do this online, that friend might read it and get angry. So we must be careful 87 what we write. Of course, blogs have good points too. People write in blogs knowing friends will read them. If you feel sad and write in 88 (you) diary, nobody may know.
