　　1. 试题

　　PartB：

　　Directions:

　　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)

　　In the movies and on television, artificial intelligence is typically depicted as something sinister 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 unemployment predictions?

　　A recent survey of manufacturing and service industries from Tata Consultancy Services found 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 personnel more valuable to employers, because they help firms prevent hacking attempts.

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

　　Better hiring practices

　　Companies are using artificial intelligence to remove some of the unconscious bias from hiring decisions. “There are experiments that show that, naturally, the results of interviews are much more biased than what AI does,” says Pédro Domingos, author of The Master Algorithm: How the Quest for the Ultimate Learning Machine Will Remake Our World and a computer science 41_____________ One company that’s doing this is called Blendoor. It uses analytics to help identify where there may be bias in the hiring process.

　　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_________These are “tools that help people use data, not a replacement for people,” says Patrick H. 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 models that more accurately access risk. “Before, they might not insure the ones who felt like a high 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 time for.

　　[B] One accounting firm, EY, uses an AI system that helps review contracts during an audit. This process, along with employees reviewing the contracts, is faster and more accurate.

　　[C] There are also companies like Acquisio, which analyzes advertising performance across multiple channels like Adwords, Bing and social media and makes adjustments or suggestions about where advertising funds will yield best results.

　　[D] You want to predict if something needs attention now and point to where it’s useful for employees to go to.

　　[E] Before, they might not insure the ones who felt like a high risk or charge them too much, or they would charge them too little and then it would cost [the company] money.

　　[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.

　　2. 真题详解

　　41. G。Better hiring practices是第一段的完整标题，在雇佣员工和招聘工作方面是本段主要叙述的内容。纵观所有选项，D选项和G选项是和招聘有关，D选项里面有employees，G选项里面有résumés和candidates。而D选项里除了employees以外，没有特别提到employees在招聘方面的相关信息;G选项则提到了人工智能可以对应聘者的简历进行筛选，而41题的周围句子反复提到与此相关的内容，故而选G。

　　42. C。More effective marketing是本段的标题内容，是和营销相关。段首句在讲解到人工智能在分析营销邮件方面的作用时用到了analyze这个动词，同样这个动词也出现在C选项的首句中，同样强调了人工智能的分析作用;同时锁定42题的前一句，其中出现了millions more in revenue，提到了钱的问题，即更多营销收入，同样C选项结尾where引导的定语从句里出现了 advertising funds will yield best results，即“广告投资能带来最好的产出”，两者都涉及到了收入和钱的内容。故而选C。C选项为例子呼应前面的内容。

　　43. E。该段标题为Saving customers’ money。该段主要讲解了人工智能在节省客户花销方面的作用，其中特别以环境和能源为例，进而列举了保险公司(insurance company)的例子，来验证相同的观点，继而引用别人的话进一步例证。根据上文相邻的句子，这句话应该是涉及到保险公司，而E选项中的insure这个动词与insurance company对应，且连续出现动词“收费”(charge)，并提到了之前让客户花销多或少的问题，与上文保险公司的内容对应，故选E。

　　44. B。本段标题为Improved accuracy，表示“提高精确性”，accuracy一词与B选项结尾的faster and more accuracy对应。整段讲述了人工智能通过改善信息精确度来帮助公司做更合理的决定，B选项中列举的公司的例子，提到了通过人工智能能使阅览合同的过程更快和更精确(fasterand more accurate)，内容上这个例子与上面的内容遥相呼应，所以选B。

　　45. D。本段内容出现了prevent equipment failure or leaks before they happen，预防潜在的失败，而D选项则强调了预测作用(predict)，内容上前后呼应，选D。
