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，代詞指代，推理判斷和主旨大意四個(gè)題型的考查，是一篇科普類閱讀，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)第三段中的“But for us to notice the remaining green light, it needs to hit something that reflects green light much better than red. That39。s still some green and even blue light hidden in there, just far less than the other colors.”可知，選A。 （3）考查代詞指代。根據(jù)第二段中的“Daytime skies are blue because blue shorter wavelengths of visible light tend to bounce off （反 射）air molecules better than red longer wavelength light.”可知，白天天空是藍(lán)色,因?yàn)樗{(lán)色短的波長(zhǎng)的可見光會(huì)反射空氣分子比紅色的長(zhǎng)波長(zhǎng)光。s a mon piece of celestial （天上的）fortunetelling that green skies mean a tornado is on its way.”和最后一段中的“Still, none of the conditions that can turn skies green are unique to the clouds that produce tornadoes. Sometimes they just lead to lots of rain, and maybe some hail.”可知，本文主要話題是關(guān)注綠色的天空是否意味著即將來(lái)臨的龍卷風(fēng)展開的，故選B。 （1）考查主旨大意。There are only red and orange lights in the sunsets.D.Storm clouds are made of water droplets and green light.B.D.Blue light.B.The sunset.Because blue light is bounced all over the sky.D.Because only blue light can be bounced in the daytime.B.A Common Piece of Celestial FortunetellingD.Why Do the Central United States Get TornadoesB.t necessarily mean there39。 Big tall threatening storm clouds are made of water droplets, and even though water is best at reflecting blue light, it can still reflect green pretty well, much better than reds and oranges, so under just the right conditions, the water in and around a cloud can bounce the green light hidden in the sunset right into our eyes making the sky look green.s still some green and even blue light hidden in there, just far less than the other colors. But for us to notice the remaining green light, it needs to hit something that reflects green light much better than red. That39。 Daytime skies are blue because blue shorter wavelengths of visible light tend to bounce off （反射）air molecules better than red longer wavelength light. So the blue light gets bounced all over the sky and looks like it39。s a mon piece of celestial （天上的）fortunetelling that green skies mean a tornado is on its way. Research has shown that it isn39。3．犇犇閱讀理解 根據(jù)最后一段中的
