　　In the following article, some sentences have been removed. For Questions 41-45, choose the most suitable one from the list A-G to fit into each of the numbered blanks. There are two extra choices, which do not fit in any of the blanks. Mark your answers on ANSWER SHEET1.(10 points)

　　Inthemoviesandontelevision,artificialintelligenceistypicallydepictedassomethingsinister that will upend our way of life. When it comes to AI in business, we often hear about it in relation to automation and the impending loss of jobs, but in what ways is AI changing companies and the larger economy that don’t involve doom-and-gloom mass unemploymentpredictions?

　　ArecentsurveyofmanufacturingandserviceindustriesfromTataConsultancyServicesfound that companies currently use AI more often in computer-to-computer activities than in automating human activities. One common application? Preventing electronic security breaches, which, rather than eliminating IT jobs, actually makes those personnelmore valuable to employers, because they help firms prevent hackingattempts.

　　Here are a few other ways AI is aiding companies without replacing employees:

　　Better hiring practices

It uses analytics to help identify where there may be bias in the hiringprocess.

　　More effective marketing

　　Some AI software can analyze and optimize marketing email subject lines to increase open rates. One company in the UK, Phrasee, claims their software can outperform humans by up to 10 percent when it comes to email open rates. This can mean millions more in revenue. 42 Theseare“toolsthathelppeopleusedata,notareplacementforpeople,”saysPatrickH. Winston, a professor of artificial intelligence and computer science at MIT.

　　Saving customers money

　　Energy companies can use AI to help customers reduce their electricity bills, saving them money while helping the environment. Companies can also optimize their own energy use and cut down on the cost of electricity. Insurance companies, meanwhile, can base their premiums on AI modelsthatmoreaccuratelyaccessrisk.“Before,theymightnotinsuretheoneswhofeltlikeahigh risk or charge them too much,” says Domingos,43

　　Improved accuracy

　　“Machine learning often provides a more reliable form of statistics, which makes data more valuable,” says Winston. It “helps people make smarter decisions.”44

　　Protecting and maintaining infrastructure

　　A number of companies, particularly in energy and transportation, use AI image processing technology to inspect infrastructure and prevent equipment failure or leaks before they happen. “If they fail first and then you fix them, it’s very expensive,” says Domingos.45

　　[A] I replaces the boring parts of your job. If you’re doing research, you can have AI go out and look for relevant sources and information that otherwise you just wouldn’t have timefor.

　　[F]We’re also giving our customers better channels versus picking up the phone to accomplish something beyond human scale.

　　[G]AI looks at résumés in greater numbers than humans would be able to, and selects the more promising candidates.

　　【参考答案】G-C-E-B-D

　　【解析】

　　41. G本题需要参考其对应的小标题内容，因为本段主要在说的是招聘实践，所以整段的内容应围绕此话题开展，再观察41题前一句在讲的是面试的结果会存在偏见，后一句提及到的代词this,为单数名词，故推断41中应提及一单数名词或者一件事，并与招聘相关，再根据最后一句提示：这一过程能够使用数据帮助确在招聘过程中偏见存在何处，则可得出G选项提及到的人工智能通过大量筛选候选者的简历为最优选择。

　　42. C 本题解题关键在于42题前后句子，前两句提及到的关键词One company, 后一句提到关键代词these说明42题的句子中涉及到复数名词，并且这些是与tools工具相关内容，C选项中不仅提到与one company 对应的 also companies, 而且后半句也提及到的multiple channels是典型的复数名词，故C为正确答案。

　　43. E 本题较前两题来讲较为简单，只需参考上句内容即可，通过观察上句的主句得知43题的内容依然是Domingos说话内容，所以主语保持不变，还是they, 并且结合上句话的内容得知与charge收费相关，只有E选项最为贴切，故正确答案为E。

　　44. B 本题与43题相似，只有上文可参考推断，同时可借助小标题的内容，本段小标题的内容与提高准确性相关，故整段内容也会围绕此话题展开，观察上句提到机器学习能够帮助人们做更智能的决定，综合考虑所有选项，B选项中提到的more accurate 与小标题的提高效率完全相符，并且也符合议论文行文特点：论点+论据，故B为正确答案。

　　45. D 本题为文章最后一句话，且与上一句一同构成Domingos的说话内容，上句话的主语为they和you,因此下一句的主语很大可能保持不变，内容主要是讲的是如果他们刚开始坏了，然后你需要修理他们，这样带来的修理费用会很昂贵，纵观选项，首先符合主语要求的只有D选项，并且D选项的内容提到一个关键词是predict,与上文中的内容AI image processing technology to inspect infrastructure and prevent equipment failure，要检查并预防设备出问题在逻辑上保持一致，故D为正确答案。
