【解析】

試題分析：通過本文考查學(xué)生的詞性在語境中的正確運用能力。包括動詞的時態(tài)，非謂語動詞，副詞，代詞，連詞，冠詞等。

【1】actually 考查副詞的用法。句意：一項新的研究表明事實上美國人牙齒問題更多。這里應(yīng)該用副詞形式actually修飾全句。

【2】problems 考查名詞的用法。句意：一項新的研究表明事實上美國人牙齒問題更多。這里應(yīng)該用名詞復(fù)數(shù)形式problems表示有各種各樣的問題。

【3】was published 考查謂語動詞的被動語態(tài)的用法。句意：該項研究被發(fā)表在英國醫(yī)學(xué)雜志 上。應(yīng)該是過去的事情，動詞和主語之間是被動關(guān)系，所以填was published。

【4】among 考查介詞的用法。句意：在年齡在25歲以上的美國人中，掉牙的情況更多。在……之中用among。

【5】worse 考查形容詞比較級的用法。句意：研究者發(fā)現(xiàn)美國窮人的牙齒比英國窮人的更糟糕，所以應(yīng)該用比較級worse。

【6】which 考查定語從句關(guān)系詞的用法。句意：英國人通過國民醫(yī)療保健制度接受牙科保健，這項服務(wù)是由納稅人資助的。只有which可以代替前面句子的意思在定語從句中做主語，所以填which。

【7】or 考查連詞固定搭配的用法。句意：在美國，人們要么花錢支付他們牙齒護理 要么買牙科保險。這里用了either…or…這個連詞，意思是: 要么……要么……。

【8】them 考查代詞的用法。句意：在美國很多窮人沒有牙科保險和牙科護理服務(wù)他們負擔(dān)不起。這里them是賓格，指前面提到的美國的窮人們。

【9】the 考查冠詞的用法。句意：經(jīng)濟合作與發(fā)展組織發(fā)現(xiàn)，在34 個成員國之中，英國有壞牙，缺牙或補牙的人數(shù)最少，美國排名居中。用the表特指。

【10】missing 考查名詞的用法。句意：經(jīng)濟合作與發(fā)展組織發(fā)現(xiàn)，在34 個成員國之中，英國有壞牙，缺牙或補牙的人數(shù)最少，美國排名居中。missing缺失的。

【題目】From self-driving cars to carebots (care+robots) for elderly people, rapid development in technology has long represented a possible threat to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations existing today will be completely unnecessary by 2025 as artificial intelligence continues to change businesses.

“The next fifteen years will see a revolution in how we work, and a revolution will necessarily take place in how we plan and think about workplaces,” said Peter Andrew, Director of Workplace Strategy for CBRE Asia Pacific.

A growing number of jobs in the future will require creative intelligence, social skills and the ability to use artificial intelligence.

The report is based on interviews with 200 experts, business leaders and young people from Asia Pacific, Europe and North America. It shows that in the US technology already destroys more jobs than it creates.

But the report states: “Losing occupations does not necessarily mean losing jobs — just changing what people do.” Growth in new jobs could occur as much, according to the research.

“The growth of 20 to 40 person companies that have the speed and technological know-how will directly challenge big companies,” it states.

A 2014 report by Pew Research found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years. The optimists pictured “a future in which robots do not take the place of more jobs than they create,” according to Aaron Smith, the report's co-author.

“Technology will continue to affect jobs, but more jobs seem likely to be created. Although there have always been unemployed people, when we reached a few billion people there were billions of jobs. There is no shortage of things that need to be done and that will not change,” Microsoft's Jonathan Grudin told researchers.

【1】According to the report, _____.

A. people won't necessarily lose jobs

B. big companies will face fewer challenges

C. small companies will win against big companies

D. most people will become interested in technology

【2】We can infer from the text that in the future _____.

A. people will face many difficulties

B. people will take up more creative jobs

C. artificial intelligence will threaten people's lives

D. most jobs will be done in traditional workplaces

【3】What is the attitude of most experts in artificial intelligence and robotics to the future?

A. Mixed. B. Worried. C. Hopeful. D. Doubtful.

【4】Jonathan Grudin's words in the last paragraph suggest that _____.

A. there will be enough jobs for people

B. things will change a lot in a few years

C. many people will become unemployed

D. technology will totally change future jobs
