He pared a plant39。 Specifically, scientists hacked the plant39。 Photosynthesis（光合作用）is the word used to describe how plants use sunlight, water, and carbon dioxide to make their own food. Scientists who conducted the new study say this is a very slow process. Plants use less than 1 percent of the energy available to therm. But by hacking a plant39。t just for puters and smartphones, According to a study published last week in the journal Science, scientists have found a way to hack a plant39。7．犇犇閱讀理解 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?？芍獎游镉貌屎缟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.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】本題考點(diǎn)涉及代詞指代，推理判斷和主旨大意三個(gè)題型的考查，是一篇科普類閱讀，考生需要根據(jù)上下文進(jìn)行邏輯推理，概括歸納，從而選出正確答案。 （3）考查推理判斷。 （2）考查主旨大意。根據(jù)第一段中的“While you39。To argue against the control of chemicals.【答案】 （1）D（2）B（3）A 【解析】【分析】本文是一篇說明文，用擬人的手法，以蜂蜜的口吻，介紹了蜜蜂雖然只有六周左右的壽命，但用其一生辛勤為人類釀造蜂蜜，人類應(yīng)該保護(hù)蜜蜂。To talk about the history of a treasure.C. social behavior.（3）What is the purpose of the passage?
