【文章內容簡介】 .A famous camouflage strategyB.Metallic iridescent as the best disguiseC.Colors unique to animalsD.Shining colors as a sexual strategy【答案】 （1）D（2）C（3）C（4）B 【解析】【分析】本文是一篇說明文，介紹了彩虹色有助于生物隱藏。 （1）考查細節(jié)理解。根據第一段中的“A good disguise keeps you hidden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被動物用來通過逃離捕食者而活得更久，排除A；根據第三段中的“Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄兩性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在這里我想指出的是，在某些物種中，尤其是那些表現出強烈兩性差異的物種，比如天堂鳥、孔雀，甚至在某些蝴蝶或魚類中，彩虹色的出現很可能是由性別選擇所驅動的?？芍獎游镉貌屎缟鹜榈淖⒁?，排除B；根據倒數第二段中的“The idea that eye173。catching colors could be used as a cover173。up isn39。t a new one.”引人注目的顏色可以用來偽裝，這種想法并不新鮮，排除C，故選D。 （2）考查細節(jié)理解。根據最后一段中的“It seemed that the strikingly iridescent surfaces on our targets visually broke up the otherwise recognizable shape of the targets, which made them hard to distinguish.”似乎我們的目標上驚人的彩虹表面在視覺上打破了原本可以辨認的目標形狀，這使得它們很難區(qū)分。故選C。 （3）考查推理判斷。根據最后一段說研究人員目前正在對鳥類進行實驗，這些鳥類的飲食中經常含有彩虹色的昆蟲。實驗目的是看看鳥類的視角是否能提供幫助。由此推斷接下來一段會談論 為什么鳥類不受彩虹色昆蟲的影響，故選C。 （4）考查主旨大意。第一段中的“Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金屬彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”有時，最好的偽裝其實是最耀眼的偽裝，因為研究表明，閃光的金屬彩虹色能在視覺上迷惑捕食者，這讓五顏六色的獵物能夠再存活一天，是全文的主題句，結合全文內容，可知這篇文章主要講了彩虹色有助于生物隱藏，故選B。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據上下文的邏輯關系，進行分析，推理，概括和歸納，從而選出正確答案。4．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?

AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can.”可知四種類型的工作完全沒有風險。首先,有創(chuàng)造性的工作。人工智能不可能像科學家,小說家和藝術家那樣進行發(fā)明創(chuàng)造。也就是作家和科學家不會被取代。排除A；再根據第四段中的“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.” 可知作者認為在AI時代仍然會有工作,關鍵必須是對勞動力進行再培訓,這樣人們才能從事這些工作。進行培訓是為了得到專業(yè)技能,由此推斷作者會給出一直提升人們的專業(yè)技能的建議,故選D。 【點評】本題考點涉及細節(jié)理解，詞義猜測和
