Do you sometimes feel uncomfortable on your neck and back? It may be because of the radiation (辐射) from your computer. If you spend three hours or more in front of a computer, you may feel terrible because of the radiation. The safe amount of radiation is 25V/m. Do you know how much radiation our computers give off? Keyboard: 1,000 V/m Mouse: 450 V/m Monitor: 218V/m CPU: 170 V/m Laptops: 2,500 V/m Ways to protect yourself from harmful computer radiation: ①Put some green plants on your desk. They can take in radiation. ②Drink two to three cups of green tea a day and eat an orange daily. ③Use a screen filter (屏幕过滤器) for your monitor. ④Avoid having metal (金属的) objects near your desk. ⑤Put the back of the computer to the wall. Most of the radiation comes from the back. ⑥Keep your monitor at least 50 cm away from your face. ⑦Allow fresh air to move around your computer room. ⑧Eat healthily especially fruit and vegetables. ⑨Turn off your computer if you have to rest nearby. 43.

To tell us how to keep ourselves off computer radiation. (B) Do you know ChatGPT? It’s an artificial intelligence (AI) tool. It can answer questions, tell stories, and write articles. But it’s very “thirsty”, said a new study from Harvard University. ChatGPT has “homes” around the world in data centers (数据中心). When it works, the computers at the data centers get very hot. Workers then have to use water to cool them down. Cold water goes into pipes near the computers. The water needs to be very clean. They can’t use seawater because it can eat away at (侵蚀) the pipes. When you ask ChatGPT 50 questions, it “drinks” 500 milliliters (ml) of water. Scientists used 700,000 liters of water to build ChatGPT. The water use is very big. People can make 370 cars with it. ChatGPT is just one of the AI tools around the world. You need data centers to do everything on the Internet. There are more than 8,000 data centers around the world. The number is still growing. AI uses a lot of water to “grow”. The world’s water may not be enough. Many people don’t have enough water to drink. But AI technology helps people. Should we rethink how we use AI? 47. Which of the following can ChatGPT do? ①Answer questions. ②Sing songs. ③Write articles. ④Tell stories. A. ①②③ B. ②③④ C. ①③④ D. ①②④ 48. What does “them” refer to in Paragraph 2? A. Homes. B.

AI tools can work in a better way without any water. D. We may have to “fight” with AI for water in the future. 50. What is the main idea of the article? A. ChatGPT is a good artificial intelligence tool. B. ChatGPT needs lots of water when it works. C. ChatGPT helps people do many different things. D. ChatGPT has “homes” around the world in data centers. (C) Most of us cannot imagine modern life without social media (社交媒体). We use it almost every day in order to keep up with what is happening in our friends’ lives, or find out the latest information. The greatest advantage of social media is that we can connect with people much more easily. We are still able to keep in touch with our friends if they are far away. Also, it makes it easier for us to make friends, especially for those who are afraid of making friends face to face. Are you shy? If yes, social media has probably helped. Social media is also ideal (理想的) for making yourself heard. Anyone with a voice can express it. Anyone with a talent is free to show it. Moreover, anyone with a smartphone and the Internet can be a reporter. As a result, it has become much faster to cover the news than ever before. Social media, on the other hand, can make us less confident sometimes. A study found that the more a person uses social media, the sadder he feels about his own life. One reason for this is that people around us put colourful information and perfect pictures online in order to show off their best moment. So we often get an incorrect sense of how wonderful their lives are, compared to our own. Social media does not cause sadness; it simply provides another tool for us to use. Is it good or bad? Nobel Peace Prize winner Malala Yousafzai says, “What is interesting is the power and influence of social media. We must try to use social media in a good way.” After all, you decide how you use this powerful tool. 51. What CAN’T people do with the social media according to the passage? A. Make friends. B. Be a reporter. C. Show their talent. D. Do the housework. 52. What is the greatest advantage of social media according to the passage? A. Expressing our voices freely. B. Showing our talents to others. C. Recording the best side of our life. D. Connecting with people more easily. 53. Why may a person be less confident on the social media according to Paragraph 4? A. Because he can’t make friends face to face. B. Because he can’t make money on the Internet. C. Because of the incorrect sense of other people’s lives. D. Because of the unhappy moments with his friends. 54. Which picture shows the structure (结构) of the passage? (①=Paragraph 1, ...) A. B. C. D. Ⅴ．五选四(每题2分，共8分) We are all busy talking about and using the Internet, but how many of us know the history of the Internet? Many people are surprised when they find that the Internet was set up in 1969. ____55____ Not everyone could afford a computer. The computer networks (网络) didn’t work well. If one computer in the network broke down, then the whole network stopped. So people had to set up a new network system. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way, the computer network system would keep on working all the time. ____56____ The government (政府) got a lot of help from it. But in the early 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. ____57____ Many people could use them. Scientists also developed software that made surfing the Internet more convenient. Today it is easy to surf the Internet and millions of people use the Internet to talk with each other every day. Sending messages by WeChat is more and more popular among people. ____58____ A. Computer network system was important. B. At that time, computers were large and expensive. C. At first, only the government could use the Internet. D. By the start of the 1990s, computers became cheaper and easier to use. E. The Internet has now become one of the most important parts of people’s lives.

It’s an artificial intelligence (AI) tool. It can answer questions, tell stories, and write articles. But it’s very “thirsty”, said a new study from Harvard University. ChatGPT has “homes” around the world in data centers (数据中心). When it works, the computers at the data centers get very hot. Workers then have to use water to cool them down. Cold water goes into pipes near the computers. The water needs to be very clean. They can’t use seawater because it can eat away at (侵蚀) the pipes. When you ask ChatGPT 50 questions, it “drinks” 500 milliliters (ml) of water. Scientists used 700,000 liters of water to build ChatGPT. The water use is very big. People can make 370 cars with it. ChatGPT is just one of the AI tools around the world. You need data centers to do everything on the Internet. There are more than 8,000 data centers around the world. The number is still growing. AI uses a lot of water to “grow”. The world’s water may not be enough. Many people don’t have enough water to drink. But AI technology helps people. Should we rethink how we use AI? 47. Which of the following can ChatGPT do? ①Answer questions. ②Sing songs. ③Write articles. ④Tell stories. A. ①②③ B. ②③④ C. ①③④ D. ①②④ 48. What does “them” refer to in Paragraph 2? A. Homes. B. Computers. C. Workers. D. Pipes. 49. What can we learn from Paragraph 4 and Paragraph 5? A. ChatGPT is the only AI tool around the world. B. The number of data centers is not growing now. C. AI tools can work in a better way without any water. D. We may have to “fight” with AI for water in the future. 50. What is the main idea of the article? A. ChatGPT is a good artificial intelligence tool. B. ChatGPT needs lots of water when it works. C. ChatGPT helps people do many different things. D. ChatGPT has “homes” around the world in data centers. 【答案】47. C 48. B 49. D 50. B 【解析】 【导语】本文是一篇说明文，介绍了人工智能工具ChatGPT的工作原理及其消耗大量水资源的问题。 【47题详解】 由第一段“It can answer questions, tell stories, and write articles.”可知，ChatGPT能回答问题、讲故事、写文章，但不能唱歌。故①③④正确。 【48题详解】 由第二段“When it works, the computers at the data centers get very hot. Workers then have to use water to cool them down.”可知，“them”指代前面的computers。 【49题详解】 第四段数据中心数量仍在增长，以及第五段“The world’s water may not be enough... Should we rethink how we use AI?”可知，未来人类可能要与AI争夺水资源。 【50题详解】 文章开篇指出ChatGPT非常“口渴”，随后用数据说明其耗水量大，并引发对水资源不足的思考。 (C) Most of us cannot imagine modern life without social media (社交媒体). We use it almost every day in order to keep up with what is happening in our friends’ lives, or find out the latest information. The greatest advantage of social media is that we can connect with people much more easily. We are still able to keep in touch with our friends if they are far away. Also, it makes it easier for us to make friends, especially for those who are afraid of making friends face to face. Are you shy? If yes, social media has probably helped. Social media is also ideal (理想的) for making yourself heard. Anyone with a voice can express it. Anyone with a talent is free to show it. Moreover, anyone with a smartphone and the Internet can be a reporter. As a result, it has become much faster to cover the news than ever before. Social media, on the other hand, can make us less confident sometimes. A study found that the more a person uses social media, the sadder he feels about his own life. One reason for this is that people around us put colourful information and perfect pictures online in order to show off their best moment. So we often get an incorrect sense of how wonderful their lives are, compared to our own. Social media does not cause sadness; it simply provides another tool for us to use. Is it good or bad? Nobel Peace Prize winner Malala Yousafzai says, “What is interesting is the power and influence of social media. We must try to use social media in a good way.” After all, you decide how you use this powerful tool. 51. What CAN’T people do with the social media according to the passage? A. Make friends. B. Be a reporter. C. Show their talent. D. Do the housework. 52. What is the greatest advantage of social media according to the passage? A. Expressing our voices freely. B. Showing our talents to others. C. Recording the best side of our life. D. Connecting with people more easily. 53. Why may a person be less confident on the social media according to Paragraph 4? A. Because he can’t make friends face to face. B. Because he can’t make money on the Internet. C. Because of the incorrect sense of other people’s lives. D. Because of the unhappy moments with his friends. 54. Which picture shows the structure (结构) of the passage? (①=Paragraph 1, ...) A. B. C. D. 【答案】51. D 52. D 53. C 54. B 【解析】 【导语】本文主要介绍了社交媒体的利弊。 【51题详解】 第一段“We use it almost every day in order to keep up with what is happening in our friends’ lives, or find out the latest information.”，提到人们用社交媒体了解朋友生活、获取最新信息；第二段提到“we can connect with people much more easily”，表示社交媒体可以用来交友；第三段提到“Anyone with a talent is free to show it. Moreover, anyone with a smartphone and the Internet can be a reporter.”，表示社交媒体可以展示才华，并且可以让任何有手机的人成为报道者。全文没有提到做家务（do the housework）。 【52题详解】 第二段第一句明确指出：“The greatest advantage of social media is that we can connect with people much more easily.”，最大的优点是“与人更方便地联系”。 【53题详解】 第四段指出“One reason for...compared to our own.”，我们周围的人把丰富多彩的信息和完美的图片放在网上，以展示他们最美好的时刻，因此会让人产生一种“get an incorrect sense of how wonderful their lives are”，即“对他人生活多么美好的错误认知”。 【54题详解】 本文第一段引出话题；第二第三段介绍了社交媒体的好处；第四段介绍了社交媒体的弊端；第五段进行了总结，选项B符合文章结构。 Ⅴ．五选四(每题2分，共8分) We are all busy talking about and using the Internet, but how many of us know the history of the Internet? Many people are surprised when they find that the Internet was set up in 1969. ____55____ Not everyone could afford a computer. The computer networks (网络) didn’t work well. If one computer in the network broke down, then the whole network stopped. So people had to set up a new network system. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way, the computer network system would keep on working all the time. ____56____ The government (政府) got a lot of help from it. But in the early 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. ____57____ Many people could use them. Scientists also developed software that made surfing the Internet more convenient. Today it is easy to surf the Internet and millions of people use the Internet to talk with each other every day. Sending messages by WeChat is more and more popular among people. ____58____ A. Computer network system was important. B. At that time, computers were large and expensive. C. At first, only the government could use the Internet. D. By the start of the 1990s, computers became cheaper and easier to use. E. The Internet has now become one of the most important parts of people’s lives. 【答案】55. B 56. C 57. D 58. E 【解析】 【导语】本文讲述了互联网从建立之初到现在的发展历程，包括其早期的状况、使用范围的扩大、技术的改进以及如今在人们生活中的重要地位。 【55题详解】 第一段第二句“Not everyone could afford a computer.”，此句描述当时人们买不起电脑的情况，与“At that time, computers were large and expensive.”（那时，电脑又大又贵）相呼应，说明买不起电脑是因为其又大又贵。买不起电脑是结果，电脑又大又贵是原因，B选项能合理衔接上文提到的1969年互联网建立时的情况。 【56题详解】 第二段第一句“The government (政府) got a lot of help from it.”，“it”指代互联网，从“got a lot of help from it”可知前文应提及政府使用互联网。C选项“At first, only the government could use the Internet.”表明起初只有政府能使用互联网，与后文政府从互联网得到帮助相承接。 【57题详解】 第二段“However, computers were still very expensive and the Internet was difficult to use.”以及“Many people could use them. Scientists also developed software that made surfing the Internet more convenient.”，前文说电脑贵且互联网难用，后文说很多人能用且上网更方便，中间应是电脑情况的转变。D选项“By the start of the 1990s, computers became cheaper and easier to use.”说明到20世纪90年代初，电脑变得更便宜且易用，使得很多人能够使用，很好地衔接了上下文。 【58题详解】 最后一段“Today it is easy to surf the Internet and millions of people use the Internet to talk with each other every day. Sending messages by WeChat is more and more popular among people.”，描述了如今互联网的使用情况，是对互联网重要性的阐述。E选项“The Internet has now become one of the most important parts of people’s lives.”（互联网现在成为人们生活中最重要的部分之一）是对如今互联网在人们生活中地位的总结，与前文内容相符，所以选E。 Ⅵ．短文填空(每题1分，共10分) 阅读下面短文，在空白处填入一个适当的单词或括号内单词的正确形式。 Chen Yuanchun is a primary school teacher in Cangyuan, Yunnan Province. ___59___ 44-year-old woman teaches Chinese, but she is very interested in computer technology.

Many people make and share short videos on popular video apps like Douyin and Kuaishou. Young people can even add music and special effects (特效) to their videos. The videos are a few minutes long. They show people doing activities like cooking, exercising and singing. Teenagers especially enjoy these videos. More than 50% of the high school students say they enjoy watching these short videos. About 47% have posted (发布) their own videos, according to a report by China National Youth Palace Association. The videos let young people see funny and exciting things they don’t usually see. Many young people like to share the fun things they do with others. However, the videos can also cause trouble. Some students spend too much time watching them and not enough time studying. Some videos have a bad effect (影响) on young people. So Douyin added a new function (功能) in April, 2018. It will lock the app if someone uses the app for over two hours a day.

In ②. addition 【解析】 【详解】原句中“此外”是关键词，表示“此外”的短语是in addition。因位于句子开头，第一个单词的首字母I大写。应填In；addition。 76. 你可能没意识到你周围计算机（的存在）。 You may be ________ ________ the computers around you. 【答案】 ①. unaware ②. of 【解析】 【详解】原句中“没意识到”是关键词，表示“没意识到”的短语是be unaware of 。句中已含有情态动词may和be动词（may be），后面需接形容词作表语。unaware是形容词，意为“未意识到的”。故填unaware；of。 77. 如果电脑能做我们所有的工作，我们会发生什么事情呢? What will ________ ________ us if computers can do all our jobs? 【答案】 ①. happen ②. to 【解析】 【详解】原句中“发生在……身上”是关键词。英语中“发生在某人身上”的固定短语是happen to sb.。句中含有助动词will，表示一般将来时，will后面必须接动词原形，因此第一空填happen，第二空填介词to。 Ⅸ．划线部分提问(每空1分，满分6分) 78. The first computers were bigger than cars. ________ ________ the first computers like? 【答案】 ①. What ②. were 【解析】 【详解】句意：第一批电脑比小汽车大。根据句末的介词like可知，此处考查“What+be+主语+like?”，意为“……是什么样的？”，用来询问事物的特征或外貌。询问“什么样”需用特殊疑问词What置于句首。原句“The first computers were…”是一般过去时，且主语“the first computers”为复数，因此be动词应使用were。故填What；were。 79. We can type and draw things with computers. ________ can you ________ with computers? 【答案】 ①. What ②. do 【解析】 【详解】句意：我们可以用电脑打字和画画。划线部分“type and draw things”意为“打字和画画”，表示具体的行为动作（做什么）。对行为或事物提问，特殊疑问词应用What。在对动作提问时，原句中的具体动词在疑问句中需用通用动词do来代替。句型结构：特殊疑问词（What）+情态动词（can）+主语（you）+动词原形（do）+其他。故填What；do。 80. I bought my first computer five years ago. ________ ________ you buy your first computer? 【答案】 ①. When ②. did 【解析】 【详解】句意：五年前我买了第一台电脑。划线部分“five years ago”（五年前）表示时间，对时间提问需用特殊疑问词When。原句谓语动词“bought”是过去式，表明时态为一般过去时。变为特殊疑问句时，需借助助动词did提到主语前，且动词恢复原形（buy）。故填When；did。 第1页/共1页 学科网（北京）股份有限公司 $听说测评一短对话理解，根据对话内容选择最佳答案，每段对话读一遍。One, what do you usually do with your computer?
