But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (觸發(fā))by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process.Solar energy is only available about half the time we need it — during daylight. For the sun to bee a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun39。 作者開頭提出老年人更關注積極的事情，后文提到積極的情緒會增強免疫系統(tǒng)，所以本文主要講的是年齡，健康與積極的情緒之間的關系，選B。re not.可知當我們快樂時，我們的免疫系統(tǒng)進化到最大程度，但是當我們不快樂時，免疫系統(tǒng)會減弱。也就是說積極與免疫功能之間有關系，越積極，免疫功能越強，就能活得越久，所有選項中D項（樂觀與壽命）之間最切題，故選D。由此可以推斷，免疫系統(tǒng)會暫時停止來為身體提供額外的能量。特里弗斯合作研究身體是如何使用能量的，他們的發(fā)現(xiàn)解釋了這一現(xiàn)象。Ancestors, emergency and evolutionRealizing that their days are numbered, older people prefer being positive.D.optimism and length of life（3）What can be concluded from Robert Trivers39。happiness and biological evolutionC.experiences and related knowledgemuscles will respond to it by relaxing a little bitB.re being chased by a tiger, you don39。s increased positive outlook.

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。t a new one. The father of camouflage theory, Abbott Thayer, really believed that iridescence should be categorized as a camouflage strategy.
