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，推理判斷和主旨大意四個(gè)題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。因此本文的最好的題目就是“狗能識(shí)別人的情緒”。第一段提出文章的主旨即“每個(gè)狗的主人都知道他們的狗狗能很好地讀懂他們的情緒，但科學(xué)家們一直有點(diǎn)懷疑。故選C。 （3）考查推理判斷。根據(jù)第五段中的They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly以及However可知，與前面意思相反，以及劃線詞后的disappear可知once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear.…此句為，狗看到生氣的表情后會(huì)感到厭惡，并由此退縮，但是一旦聰明的狗意識(shí)到會(huì)有獎(jiǎng)勵(lì)之后，它們的恐懼以及退縮就會(huì)消失。故選D。 （1）考查細(xì)節(jié)理解。s happy or angry faces.（2）The underlined word trepidation in Paragraph 5 probably means ________. and hesitation and eagerness and happiness and sadness（3）According to the last paragraph, dogs with female owners ________. fond of the male faces uninterested in telling the emotions on the entire faces difficulty telling the moods on the faces of males only recognize emotions of females（4）What is the best title for this passage? Changes Influence Dogs Identify the Moods and Their Owners39。 They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the puter game That scientists had a hard time keeping them away from the touch screens after the study was pleted.s because the scientists believe humans show their emotions on their entire face. For their study, biologist Corson Miller and his team exposes eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry. 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科教類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。根據(jù)第四段中的“The study suggested that the more the robot was humanized, the less likely participants were to sacrifice it.”及全文內(nèi)容可知，文章主要敘述了隨著越來越多的機(jī)器人具有人性化，參與者就可能越不會(huì)犧牲機(jī)器人。故選B。 （3）考查推理判斷。根據(jù)第三段中的“According to Sari Nijssen, the study set out to answer the following question:‘ Under what circumstances would adults be willing to sacrifice robots to save human lives?’可知，在這項(xiàng)研究中，參與者可能必須決定何時(shí)犧牲機(jī)器人。故選B。 （1）考查細(xì)節(jié)理解。Robot Saved, People Take the HitD.Robots, A Must for FutureB.Certain moral status should be attached to robots.D.Humanized robots offer less help to people.B.what robots should be like（3）What can be inferred from Paulus39。where to experience risksC.How to find more applications.（2）In the study the participants probably have to decide ________.
