【正文】 0。D.Water.（4）What can we learn about from the text? A.Storm clouds are made of water droplets and green light.B.Water can reflect red light as well as blue light.C.There are only red and orange lights in the sunsets.D.If you see a green sky, there will be a tornado.【答案】 （1）B（2）C（3）A（4）B 【解析】【分析】本文是一篇說(shuō)明文，科學(xué)家發(fā)現(xiàn)天空呈現(xiàn)綠色并不是產(chǎn)生龍卷風(fēng)的云層所獨(dú)有的，有時(shí)它們會(huì)導(dǎo)致大量降雨，甚至冰雹，待在室內(nèi)或許是最好的選擇。 （1）考查主旨大意。通讀全文，根據(jù)第一段中的“there39。s a mon piece of celestial （天上的）fortunetelling that green skies mean a tornado is on its way.”和最后一段中的“Still, none of the conditions that can turn skies green are unique to the clouds that produce tornadoes. Sometimes they just lead to lots of rain, and maybe some hail.”可知，本文主要話題是關(guān)注綠色的天空是否意味著即將來(lái)臨的龍卷風(fēng)展開(kāi)的，故選B。 （2）考查細(xì)節(jié)理解。根據(jù)第二段中的“Daytime skies are blue because blue shorter wavelengths of visible light tend to bounce off （反 射）air molecules better than red longer wavelength light.”可知，白天天空是藍(lán)色,因?yàn)樗{(lán)色短的波長(zhǎng)的可見(jiàn)光會(huì)反射空氣分子比紅色的長(zhǎng)波長(zhǎng)光。故選C。 （3）考查代詞指代。根據(jù)第二段中的“The sunset might look exclusively （獨(dú)有的）red and orange, but there39。s still some green and even blue light hidden in there, just far less than the other colors.”可知，選A。 （4）考查推理判斷。根據(jù)第三段中的“But for us to notice the remaining green light, it needs to hit something that reflects green light much better than red. That39。s where water es in.”可知，水既能反射藍(lán)光，也能反射紅光，故選B。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，代詞指代，推理判斷和主旨大意四個(gè)題型的考查，是一篇科普類(lèi)閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。7．閱讀理解 In 2015, a man named Nigel Richards memorized 386, 000 words in the entire French Scrabble Dictionary in just nine weeks. However, he does not speak French. Richards39。 impressive feat is a useful example to show how artificial intelligence works—real AI. Both of Richard and AI take in massive amounts of data to achieve goals with unlimited memory and superman accuracy in a certain field. The potential applications for AI are extremely exciting. Because AI can outperform humans at routine tasks—provided the task is in one field with a lot of data—it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so. But not every job will be replaced by AI. In fact four types of jobs are not at risk at all. First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can. Second, the plex, strategic jobs—executives, diplomats, economists — go well beyond the AI limitation of singlefield and Big Data. Then there are the asyetunknown jobs that will be created by AI. Are you worried that these three types of jobs won39。t employ as many people as AI will replace? Not to worry, as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors. These jobs require passion, trust and sympathy—which AI does not have. And even if AI tried to fake it, nobody would want a robot telling them they have cancer, or a robot to babysit their children. So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.（1）What is the main purpose of paragraph 1? A.To introduce the topic.B.To mention Nigel39。s feat.C.To stress the importance of good memory.D.To suggest humans go beyond AI in memory.（2）Which of the following best explains outperform underlined in paragraph 2? A.Be superior toB.Be inferior toC.Be similar toD.Be related to（3）Which of the following jobs is the most likely to be replaced? A.The writer.B.The shop assistant.C.The babysitter.D.The psychologist.（4）Which of the following suggestions can the author give about job replacement of AI? A.Limit the application of AI to a certain degree.B.Get more support from the government.C.Apply for the donation from panies.D.Upgrade people39。s professional skills all the time.【答案】 （1）A（2）A（3）B（4）D 【解析】【分析】本文是一篇議論文，人工智能有取代人類(lèi)工作的潛力,但是,并非所有工作都會(huì)被人工智能取代,有四種類(lèi)型的工作完全沒(méi)有風(fēng)險(xiǎn)。因此,在人工智能時(shí)代人類(lèi)仍然會(huì)有工作,關(guān)鍵必須是對(duì)勞動(dòng)力進(jìn)行再培訓(xùn),這樣人們才能從事這些工作。 （1）考查推理判斷。根據(jù)第一段可知一個(gè)名叫奈杰爾理查茲（Nigel Richards）的人在短短九周內(nèi)記住了《法國(guó)拼字游戲詞典》中的386,000個(gè)單詞。但是,他不會(huì)說(shuō)法語(yǔ)。其展示了人工智能是如何工作的。而后文主要與人工智能有關(guān),由此推斷作者寫(xiě)第一段的目的是引出人工智能這個(gè)話題。故選A。 （2）考查詞義猜測(cè)。根據(jù)第二段中的“Because AI can outperform humans at routine tasks—provided the task is in one field with a lot of data”可知AI可以在日常任務(wù)中outperform人類(lèi)（前提是該任務(wù)在一個(gè)涉及到大量數(shù)據(jù)的領(lǐng)域中；以及“it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so.”可知從技術(shù)上講,人工智能具有在未來(lái)大約15年里取代成千上萬(wàn)的白領(lǐng)和藍(lán)領(lǐng)工作的能力。結(jié)合下文推斷人工智能能夠具有取代人類(lèi)的工作是因?yàn)锳I在日常任務(wù)中表現(xiàn)超過(guò)了人類(lèi),劃線詞的意思是勝過(guò),超過(guò),故選A。 （3）考查細(xì)節(jié)理解。根據(jù)第三段中的“First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can.”可知四種類(lèi)型的工作完全沒(méi)有風(fēng)險(xiǎn)。首先,有創(chuàng)造性的工作。人工智能不可能像科學(xué)家,小說(shuō)家和藝術(shù)家那樣進(jìn)行發(fā)明創(chuàng)造。也就是作家和科學(xué)家不會(huì)被取代。排除A；再根據(jù)第四段中的“as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors.”可知需要情感的工作,例如老師,保姆和醫(yī)生也不大可能被取代,因此排除C和D。故選B。 （4）考查推理判斷。根據(jù)最后一段中的“So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them.” 可知作者認(rèn)為在AI時(shí)代仍然會(huì)有工作,關(guān)鍵必須是對(duì)勞動(dòng)力進(jìn)行再培訓(xùn),這樣人們才能從事這些工作。進(jìn)行培訓(xùn)是為了得到專(zhuān)業(yè)技能,由此推斷作者會(huì)給出一直提升人們的專(zhuān)業(yè)技能的建議,故選D。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)和推理判斷三個(gè)題型的考查，是一篇科技類(lèi)閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。8．閱讀理解 Some people sit outside for hours without getting bitten by mosquitoes, but it always seems like you39。re being eaten alive within minutes of stepping outdoors. If this is you, you39。re not alone. According to Smithsonian Magazine, around 20 percent of people in the world are especially tasty to mosquitoes. What about these people makes mosquitoes39。 mouths water? A popular myth claims that mosquitoes prefer certain blood types, but the fact is that they simply can39。t tell what your blood type is from a faraway place. Jonathon
