The hardesttoautomate industries, as it happens, are the ones that require looking after humans, such as childcare, education and health care. Robot babysitters might feel like they have scored the job of the future, but in fact, they might be better positioned.（1）What kind of robot is the one created by a startup called Starship Technologies?

The Rapid Rise and Fall of Robot Babysitters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(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行實驗，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. 【點評】本題考點涉及細節(jié)理解，詞義猜測和推理判斷三個題型的考查，是一篇科研類閱讀，要求考生準確捕捉細節(jié)信息，同時根據(jù)上下文進行邏輯推理，從而選出正確答案。由此可知。free land on Earth is used for agriculture, and according to some estimates, producing food accounts for roughly a fifth of all human173。 （3）考查細節(jié)理解。由此推斷出劃線詞所在的句子意思是我們所吃的食物給環(huán)境帶來了巨大代價。caused greenhouse gas emissions.
