【正文】 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.7．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)檠芯勘砻鳎W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猓懦鼴；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?

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)理解和主旨大意兩個(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，同時(shí)根據(jù)上下文進(jìn)行推理，歸納，從而選出正確答案。d rather think of language as product of our thought, rather than of the arrangement of our teeth. In reality, though, any given language must be both.”可知任何一種語(yǔ)言的誕生都必須同時(shí)具備思想和飲食這兩種因素的影響。 （4）考查主旨大意。根據(jù)第三段中的“The argument goes that famers eat more cooked food and more dairy than hunter gatherers.”可知農(nóng)民比狩獵采集者吃更多的熟食和奶制品，即農(nóng)民們發(fā)f和v音的原因是他們喜歡吃更多的熟食。故選D。根據(jù)第二段中的“New research suggests that the apparently arbitrary distribution of some sounds around the world may be partially explained by diet.”可知某些聲音在世界范圍內(nèi)的任意分布，部分可以用飲食來解釋。根據(jù)第一段中的“By the age of one, they can recognize the significant noises around them and group them into a language.”可知一歲的嬰兒和成人相比更能識(shí)別出周圍的重要聲音，故選D。同時(shí)這也強(qiáng)調(diào)了人類特有的一切都是物質(zhì)和精神的結(jié)合:語(yǔ)言必須把聲音和意義結(jié)合起來，沒有真實(shí)的物體，意義就不可能存在或傳播。language consists of sound and meaning【答案】 （1）D（2）D（3）A（4）C 【解析】【分析】本文是一篇說明文，人們一直以來認(rèn)為語(yǔ)言是思想的產(chǎn)物，但是有新的研究表明飲食對(duì)于語(yǔ)言也會(huì)產(chǎn)生一些影響。food determines our thoughtC..
