P93 B 第一段 Last week, in a public debate in San Francisco, a software program called Project Debater beat its human opponents, including Noa Ovadia, Israel's former national debating champion.（上周，在旧金山举行的一场公开辩论中，一个名为“项目辩论者”的软件程序击败了其人类对手，其中包括以色列前全国辩论冠军诺亚·奥瓦迪亚） 可知，作者在第一段提到 Noa Ovadia 的目的是展示人工智能软件“Project Debater”的聪明。 P93 C 第二段 Brilliant though it is, Project Debater has some weaknesses. It takes sentences from its library of documents and prebuilt arguments and strings them together. This can lead to the kinds of errors no human would make.（尽管该项目非常出色，但也有其不足之处。它会从其存储的文档库和预先设定的论点中选取句子，并将它们组合在一起。这可能会导致出现一些人类绝不会犯的错误） 可知，画线词 wrinkles 所在的句子表示这样的错误毫无疑问会被纠正，wrinkles(错误)和前文提到的 errors 意思相近。 P93 B 第三段 What Hammond is referring to is the question of meaning, and meaning is central to what distinguishes the least intelligent of humans from the most intelligent of machines. A computer works with symbols. Its program specifies a set of rules to transform one string of symbols into another. But it does not specify what those symbols mean. Indeed, to a computer, meaning is irrelevant.（哈蒙德所指的正是意义这一问题，而意义是区分人类中最不聪明者与机器中最聪明者的关键所在。计算机是通过符号来进行工作的。其程序规定了一套规则，用于将一个符号串转换为另一个符号串。但它并未明确这些符号的含义。实际上，对于计算机而言，意义是无关紧要的） 可知，根据 Hammond 的说法，Project Debater 不能理解意思。 最后一段 Meaning emerges through a process of social interaction, not of computation, interaction that shapes the content of the symbols in our heads. The rules that assign meaning lie not just inside our heads, but also outside, in society, in social memory, social conventions and social relations.（意义的产生是通过社会互动的过程实现的，而非通过计算过程。这种互动塑造了我们头脑中符号的内容。赋予意义的规则不仅存在于我们的头脑之中，还存在于社会之外，存在于社会记忆、社会规范和社会关系之中） 可知，从最后一段我们能了解到社会互动是理解符号的关键。 P93 A P94 B 由上文可知,“电子邮件比传统邮件更快”,故选B （它比打电话更便宜）可以承接前文，补充电子邮件的优势 P94 E 前文讲了邮件开头的问候语，后文提到人们署名，这是邮件结尾的内容,故选E （你需要在邮件结尾有一个结束语） D P94 后文提到“有时候你写的时候句子看似清楚，但回头读就不通顺了”,故选 D（输入消息后再读一遍）对应后文的检查内容 F A P94 4. 根据下文可知，A（整理你的邮件）可以作为本段的小标题，统领全文； 5. 前文说“可以把重要邮件存进文件夹”，后文说“只需要花几分钟学习”，故选F（如果你不知道怎么做，问问朋友就好）承接上文，引出学习的内容 P97 estimated published confirm pressed functions 现在完成时的被动语态 不定式to do作目的状语 more（更多的）+ cn.复 现在完成时的被动语态 P97 plus batteries press button file agree to do sth. 同意做某事 was finished P97-98 have taken has been drawn has been translated has been checked was built has been sent has been closed have been told has been admitted 现在完成时 现在完成时 take place（发生）无被动语态 现在完成时 一般过去时 现在完成时 现在完成时 现在完成时 一般过去时 现在完成时 P98 I haven’t been told that the meeting will be put off until next Friday.

P110 A 根据第一段内容In Sweden, many teachers have been putting emphasis on printed books, quiet reading time and handwriting practice, and devoting less time to tablets, independent online research and keyboarding skills. 可判断，瑞典的许多教师认为在教育中科技应该被少用。 P110 D 根据第四段“Although Sweden’s students score above the European average for reading ability...In 2021...a drop from the 555 average in 2016.”可知，2016 年至 2021 年期间，瑞典学生的阅读能力有所下降。 P110 B 根据第六段中“In a report published in August，UNESCO...calls countries to speed up Internet connections at schools”可知，联合国教科文组织呼吁在教育中正确使用技术，以及加快学校的互联网连接。 P110 C 根据最后一段In the Swedish capital, Stockholm, Liveon Palmer, a third grader at Djurgardsskolan elementary school, agreed with the idea of spending more school hours offline. “I like writing more in school, like on paper, because it just feels better,” he said. 可知，他赞同在学校内多花时间线下学习，喜欢在学校书写，可推知他更喜欢实体书而不是数字工具。 P110 $
