In the 1970s, handwritten letters were the only main way for long-distance contact. It often took one week or longer to deliver a letter, and postage was not cheap for ordinary families. In the 1990s, landline telephones entered common families gradually, but most people only made calls on important festivals. Mobile phones appeared at the end of that period, yet they were too expensive for most teenagers. After 2010, Internet swept every corner. Emails, online chat software appeared, making communication instant. Now short-video platforms and WeChat become daily necessities. People send texts, voice messages, free video calls and share daily photos anytime anywhere. However, experts point out a new problem: many people are good at online chatting but feel nervous when talking face to face. We should balance online communication and real-life interaction. 1．What was people’s main way of long-distance communication in the 70s? A．Mobile phones. B．Letters. C．Landlines. D．WeChat. 2．Why couldn’t most teenagers own mobile phones in the 90s? A．They were too costly. B．There was no signal. C．No chat software.

We should balance online communication and real-life interaction.”可知，许多人擅长网上聊天，但在面对面交谈时却感到紧张，因此需要平衡在线沟通和现实生活中的互动。由此可推知新的通讯方式带来的问题是“人们很少面对面交流”。 4．根据第三段“Now short-video platforms and WeChat become daily necessities. People send texts, voice messages, free video calls and share daily photos anytime anywhere.”可知，现在人们可以通过微信免费打视频电话。 5．通读全文可知，文章按照时间顺序介绍了近半个世纪以来通讯工具从手写信件、固定电话、互联网通讯到如今短视频平台和微信的发展变化，“Changes in Communication Tools”最能概括全文核心内容。 B AI is playing an important role in education nowadays.

Some hospitals use big data to predict if a baby who is born too early will get sick. 4 It can be used to predict (预计) which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong. How can big data be used for good and bad things? The computer programs are written by people. People think in a certain way of ideas and thoughts, so they build a model of those ideas.

The information is then used to make bus or train systems better. Companies use big data, too”，说明政府和公司都以不同方式使用大数据。空缺处作为段落首句，应概括大数据有多种用途。选项A“Big data can be used in many ways”准确抓住了该段的核心内容，与后文对政府和公司使用大数据的描述形成总分关系。 4．前一段介绍了大数据的正面用途，如政府和公司的应用。本段前一句提到“Big data can be used for good reasons. Some hospitals use big data to predict if a baby who is born too early will get sick”，举例说明大数据用于医疗预测等善举。后文提到“It can be used to predict which kinds of people are likely to break the law or hurt others, even if they have not done anything wrong”，说明大数据也可以被用来预测哪些人可能违法，即使他们并未做错任何事。空缺处应引出大数据也可能被用于不良目的这一观点。选项C“Big data can also be used for bad reasons”与上文“for good reasons”形成对比，自然引出下文对大数据负面应用的讨论。 5．前一句提到“Sometimes, those ideas are helpful for people or businesses”，说明有些想法对人们或企业有帮助。后一句提到“So please remember we should use big data correctly”，提醒我们应该正确使用大数据。空缺处应说明不好的想法可能带来的问题。选项F“However, bad ideas can cause problems for certain groups of people”与前文形成转折关系，指出不好的想法可能会给某些群体带来问题，与后文呼吁正确使用大数据形成因果关系。 五、语法填空（共10小题，每小题1分，共10分） 根据句子意思, 用所给单词的适当形式填空。未提供单词的根据上下文填入适当的词。 We are all busy talking about and using the Internet but how many of 1 (we) know the history of the Internet?
