【正文】 ople achieve success much later in life becauseBesides sharpness of brain and experience, here is another thing that is very important, and that is wisdom. One can have a very quick, inventive brain and plenty of experience, but if one uses these foolishly, one harms both oneself and others. Wisdom does not always e with age ——there are plenty of foolish middleaged people about ——but the average person tends to learn wisdom as he gets older, usually by making painful of embarrassing mistakes. Leaning to be wise is basically learning what is not possible。 It has been discovered that after the age of sixteen, the number of our brain cells begins to decrease at a speed of several million a year. They simply die off. In certain types of activity, the human brain is at its highest point in the early twenties, when it has collected enough information to be able to use the vast number of cells freely in the most effective way. Pure mathematics is one of the fields in which this happens, and we know that Albert Einstein made all his worldshaking discoveries between the age of about 20 and 25, and spent the rest of his life tidying them up and arranging them. 【點(diǎn)評(píng)】本題考點(diǎn)涉及推理判斷，詞義猜測和主旨大意三個(gè)題型的考查，是一篇科研類閱讀，考生需要根據(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。 （4）考查主旨大意。由此推斷，消極會(huì)消耗我們身體的能量，降低對(duì)疾病的抵抗力。re happy, but to slow down dramatically when we39。 （3）考查推理判斷。根據(jù)第三段中的 being more focused on the positive things in life in an effort to enhance their immune functioning. 可知老人們更加關(guān)注生活中積極的事物，是為了增強(qiáng)他們的免疫功能。選C。因此，當(dāng)我們的身體需要額外的能量時(shí)，（我們的身體）會(huì)去找免疫系統(tǒng)。 （1）考查推理判斷。十年前作者與生物學(xué)家羅伯特D.Age, health and happinessC.Being negative drains energy from our body, lowering resistance to disease.（4）Which of the following is the best title of the passage?

A.D.immune function and healthB.brain will satisfy it by sharing optional metabolic output（2）In paragraph 3 this relationship most probably refers to the one between ______. 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)理解和推理判斷兩個(gè)題型的考查，是一篇環(huán)保類閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。根據(jù)第四段中的“ ”可知，咖啡種植者可以通過咖啡樹上方的the wood and fruit trees增加收入，故選B。 （3）考查細(xì)節(jié)理解。Coffee experts say shadegrown coffees taste better, because the beans ripen slower than coffee grown in the full sun, resulting in a richer, more plex flavor. ”咖啡專家說，陰涼處種植的咖啡味道更好，因?yàn)槎棺颖忍栂碌目Х瘸墒斓寐?，?huì)產(chǎn)生更豐富，更復(fù)雜的味道。 （2）考查細(xì)節(jié)理解。 （1）考查推理判斷。D.Purchase shadegrown coffee.B.By serving as stewards of coffee consumers.（4）What does the text suggest coffee consumers do?
