A.organs will speed up metabolic processes to answer itC.re not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, being more focused on the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the unpleasant things in life more easily.（1）According to Robert Trivers, when our body needs extra energy, ______. A. As a result, our immune system evolved to run in maximum amounts when we39。t need to waste energy making immune cells to fight off tomorrow39。 When our ancestors needed more energy than usual, perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic (新陳代謝) output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need surpasses the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, in principle, we could borrow energy when we are sitting. But the problem is that most of the energydemanding emergencies of our ancestors required a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not an effective response. This brings us to our immune system, which, when strong, protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the service of keeping us healthy in the future. We have an enormous number of immune cells coursing through our body, a momentary break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function. When you39。 Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they prioritize positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on his idea that there was an evolutionary basis for older people39。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測(cè)，推理判斷和主旨大意四個(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。因此，本文的最佳標(biāo)題應(yīng)為“若何保護(hù)動(dòng)物脫險(xiǎn)的建議”。 （4）考查主旨大意。結(jié)合四個(gè)選項(xiàng)可知，此處用Making one heartbroken（心碎）最合句意。根據(jù)上文大家對(duì)干涉動(dòng)物的行為有不同觀點(diǎn)，再結(jié)合下文的“you stay out of the way. Even when you39。t bothering, right? viewer Kathryn Shaw said on her Facebook.”可知，她對(duì)幫助動(dòng)物是很贊成的，故選A。根據(jù)第三段中的“I39。故選B。 （1）考查細(xì)節(jié)理解。s various remarks on penguins. rescue of penguins from a gully. penguins39。s no rule book in those situations.
