【分析】本文是一篇議論文,作者用研究事實(shí)來證明蝙蝠在飛行及運(yùn)動(dòng)方式與鳥類完全不同。Bats can adjust speed before landing.B.Bats might hurt themselves when landing.D.the flying directionB.They hide in tree branches.(3)The word it (in 2nd paragraph) probably refers to ______. A.They sleep upside down.C.Ways in which bats move differently from birds.(2)Which of the following is a false assumption about bats that was recently corrected? A.Why scientists have difficulty observing bats.C. these will vary depending on the area where a bat species makes its home. For example, a cave bat, which regularly lives on a hard stone ceiling, is more careful about its landing preparation than a bat more accustomed to landing in leafy treetops.(1)Which of the following is the topic of the passage? A. In the past it was believed that, in terms of flying mechanics, there was little difference between bats and birds. This belief was based only on assumption, however, because for years nobody had actually studied in detail how bats move their wings. In recent years, though, researchers have discovered a number of interesting facts about bat flight. Bats are built differently from birds, and their wings are made up of both their front and hind limbs (肢體). This makes coordinating (協(xié)調(diào)) their limbs more difficult for bats and, as a result, they are not very good at flying over longer distances. However, they are much better at the ability to adjust themselves: a bat can quickly change its direction of flight or pletely reverse it, something a bird cannot easily do.4.犇犇Choose the one that fits best according to the information given in the passage you have just read. 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(shí),最好的偽裝其實(shí)是最耀眼的偽裝,因?yàn)檠芯勘砻?,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(jié)合全文內(nèi)容,可知這篇文章主要講了彩虹色有助于生物隱藏,故選B。由此推斷接下來一段會(huì)談?wù)?為什么鳥類不受彩虹色昆蟲的影響,故選C。根據(jù)最后一段說研究人員目前正在對(duì)鳥類進(jìn)行實(shí)驗(yàn),這些鳥類的飲食中經(jīng)常含有彩虹色的昆蟲。故選C。 (2)考查細(xì)節(jié)理解。up isn39??芍?jiǎng)游镉貌屎缟鹜榈淖⒁?,排除B;根據(jù)倒數(shù)第二段中的“The idea that eye173。 (1)考查細(xì)節(jié)理解。D.Colors unique to animalsB.Which camouflage theory applies more to birds.(4)Which of the following might serve as the best title of the passage? A.Some industries that have great interest in camouflage.C.Bees are likely to prefer circles to ovals, whether they are iridescent or not(3)What will be talked about in the following paragraph? A.Bees are creatures that are fascinated by sweet things that are iridescentC.catch sight of more colorful preys(2)From the study in the last paragraph, we can learn that ________. A.conceal themselves when in dangerB.eye view.(1)According to the passage, iridescence is not made use of by animals to ________. A. In a similar way, we were asking whether iridescence, due to its changeability, could work as a form of camouflage by preventing shape recognition. Kjernsmo and her colleagues trained bumblebees to associate a particular shape—a circle or an oval—with a sugar reward. And they found that the bees, when given a choice, would preferentially visit the shape they knew to be sweet. But when the shapes were iridescent, the bees had trouble telling them apart. 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. As for making use of this method for hiding in plain sight, Any practical applications is of course directly linked to any industry that has an interest in camouflage, that is how to conceal objects or make them more difficult to recognize. The researchers are currently conducting experiments with birds, which often prey on iridescent insects to see if it helps to have a bird39。. And this sounds like a pletely unreasonable thing to say, because how can colors that are both brilliant and changeable contribute to animal39。brilliantly changeable or metallic colors are among the strongest factors in an animal39。t a new one. The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy. And he wrote in his famous lifework Concealing173。catching colors could be used as a cover173。But iridescence also shows up in situations where reproduction is not an issue. So what we are studying now is whether natural selection imposed by predation(捕食行為) could explain the occurrence of iridescence in prey animals. s viewed, is favored by everything from birds to beetles and blossoms to butterflies. 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. Those surprising results appear in the journal Scientific Reports. 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解,詞義猜測和推理判斷三個(gè)題型的考查,是一篇科研類閱讀,考生需要準(zhǔn)確掌握細(xì)節(jié)信息,并根據(jù)上下文的邏輯關(guān)系,進(jìn)行分析,推理,從而選出正確答案。根據(jù)最后一段中的Instead of waiting for people to get worse, we will be able to treat them earlier. 可知,這項(xiàng)技術(shù)將能夠更早地治療患者,而不是坐等病情惡化,從而推斷,人工智能這一科技幫助醫(yī)生對(duì)疾病診療早預(yù)判,早介入,從而幫助挽救大量生命,將大大促進(jìn)衛(wèi)生服務(wù)。故選A。 (3)考查推理判斷。根據(jù)第三段中的“Computers assess blood test results by picking up subtle changes in red and white blood cells, suggesting a patient is going downhill.”可知,計(jì)算機(jī)通過檢測紅細(xì)胞和白細(xì)胞的細(xì)微變化來評(píng)估血液檢測結(jié)果。故選C。根據(jù)第二段中的“so doctors can take early action to prevent death or serious illness. ”以便醫(yī)生能夠及早采取行動(dòng),預(yù)防死亡或嚴(yán)重疾病,可以猜測出,人工智能將用于對(duì)高危病人進(jìn)行“篩查”。It is intended for patients with kidney diseases.【答案】 (1)C(2)C(3)A(4)C 【解析】【分析】本文是一篇說明文,介紹超級(jí)計(jì)算機(jī)能夠分析血樣并預(yù)測哪些病人可能會(huì)患上重病,每年可以挽救數(shù)萬人的生命。It has helped save thousands of lives.C.To pr
