2、 to survive another day. Those surprising results appear in the journal Scientific Reports. Shining iridescent color, which changes depending on the angle from which its viewed, is favored by everything from birds to beetles and blossoms to butterflies. And in our research group we are of course int
3、erested in why this vivid metallic color is so widespread in nature. Karin Kjernsmo of the University of Bristol adds that in some cases the showy splashes of light are a sexual strategy. Here I would like to point out that in some species, particularly those that display strong sexual dimorphism(雌雄
4、两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection. For example, in many of these cases it is the males that have these vivid iridescent colors and they use them in mate choice or they use them as a signal to attract
5、mates. 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(捕食行为) could explain the occurrence of iridescence in prey animals. The idea that eyecatching colors could be used as a coverup isnt a n
6、ew 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 ConcealingColoration in the Animal Kingdom, already in 1909, that brilliantly changeable or metallic colors are among the stron
7、gest factors in an animals concealment. And this sounds like a completely unreasonable thing to say, because how can colors that are both brilliant and changeable contribute to animals concealment？ In a similar way, we were asking whether iridescence, due to its changeability, could work as a form o
8、f camouflage by preventing shape recognition. Kjernsmo and her colleagues trained bumblebees to associate a particular shapea circle or an ovalwith 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
9、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 appl
10、ications 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 bird
11、seye view.（1）According to the passage, iridescence is not made use of by animals to _. A.live a little longer by escaping their predator(捕食者)B.catch the attention of their matesC.conceal themselves when in dangerD.catch sight of more colorful preys（2）From the study in the last paragraph, we can lear
12、n that _. A.Bees can always tell the difference between a circle and an ovalB.Bees are creatures that are fascinated by sweet things that are iridescentC.If a circle, with a sugar reward, is iridescent, the bees may have difficulty finding itD.Bees are likely to prefer circles to ovals, whether they
13、 are iridescent or not（3）What will be talked about in the following paragraph? A.Whether there are any differences between bees and birds.B.Some industries that have great interest in camouflage.C.Why birds are not effected by iridescent insects.D.Which camouflage theory applies more to birds.（4）Whi
14、ch of the following might serve as the best title of the passage? A.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】本文是一篇说明文，介绍了彩虹色有助于生物隐藏。 （1）考查细节理解。根据第一段中的“A good disguise keeps you h
15、idden, right? Well, sometimes the best disguise is actually the most dazzling because research reveals that flashy metallic iridescence(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”可知彩虹色被动物用来通过逃离捕食者而活得更久，排除A；根据第三段中的“Here I would like to point out that in s
16、ome species, particularly those that display strong sexual dimorphism(雌雄两性), such as birds of paradise or some butterflies or fishes, the occurrence of iridescence is most likely driven by sexual selection.”在这里我想指出的是，在某些物种中，尤其是那些表现出强烈两性差异的物种，比如天堂鸟、孔雀，甚至在某些蝴蝶或鱼类中，彩虹色的出现很可能是由性别选择所驱动的。可知动物用彩虹色引起同伴的注意，排
17、除B；根据倒数第二段中的“The idea that eyecatching colors could be used as a coverup isnt a new one.”引人注目的颜色可以用来伪装，这种想法并不新鲜，排除C，故选D。 （2）考查细节理解。根据最后一段中的“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 dist
18、inguish.”似乎我们的目标上惊人的彩虹表面在视觉上打破了原本可以辨认的目标形状，这使得它们很难区分。故选C。 （3）考查推理判断。根据最后一段说研究人员目前正在对鸟类进行实验，这些鸟类的饮食中经常含有彩虹色的昆虫。实验目的是看看鸟类的视角是否能提供帮助。由此推断接下来一段会谈论 为什么鸟类不受彩虹色昆虫的影响，故选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 iridescenc
19、e(金属彩虹色) can visually puzzle predators, which allows colorful prey to survive another day.”有时，最好的伪装其实是最耀眼的伪装，因为研究表明，闪光的金属彩虹色能在视觉上迷惑捕食者，这让五颜六色的猎物能够再存活一天，是全文的主题句，结合全文内容，可知这篇文章主要讲了彩虹色有助于生物隐藏，故选B。 【点评】本题考点涉及细节理解，推理判断和主旨大意三个题型的考查，是一篇科研类阅读，要求考生在捕捉细节信息的基础上，进一步根据上下文的逻辑关系，进行分析，推理，概括和归纳，从而选出正确答案。2犇犇阅读理解 In ou

22、lity of your developing Alzheimers disease（AD）. The researchers in a new study show that its not forgetfulness but not being aware that were forgetful that we should fear. The researchers began with the assumption that one common feature of Alzheimers dis-ease is a damaged awareness of illness. And
23、they wanted to prove their theory that the lack of awareness can be used to predict whether someone with mild cognitive（认知的）damage will progress to full-on AD.

The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an
25、objective marker of the sort of reduced brain function that goes along with AD.As expected, glucose uptake was reduced in those with AD. What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness.
26、 Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.（1）What can be implied from paragraph 1？ A.People can be forgetful at different ages.B.The memory of the young is better than the old.C.Old people are most afraid of getting

31、m a bit dreadful. ”在二十多岁的时候，当我们记不起邻居的猫的名字或是主演一部著名电影的英俊演员时，我们觉得很有趣。在三十多岁的时候，我们开玩笑地称它为“大脑冻结”，在四十多岁的时候，我们把它当作“老年时期”来嘲笑，然后继续讲这些老年笑话。但现实是，有这样的时候，健忘不再有趣，而且看起来有点可怕，可推知选A。 （2）考查细节理解。根据第二段中的“ The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimers disease（AD） ”承认自己的健忘也许是一个很好的迹象，至少从你患老年痴呆症,的可能性来看，可知选C。 （3）考查细节理解。根据第四段中的“ It is an objective marker of the sort of reduced brain function that goes along with AD.As expected, glucose uptake was reduced in those with AD. ”这是一个患有老年痴呆症降
