【正文】 o 122, so it wouldn39。t surprise me if someone alive today reaches 130 or 135, says Jerry Shay at the University of Texas. Steve Austad at the University of Texas agrees. People can live much longer than we think, he says. Experts used to say that humans couldn39。t live past 110. When Calment blew past that age, they raised the number to 120. So why can39。t we go higher? The trouble with guessing how old people can live to be is that it39。s all just guessing. Anyone can make up a number, says Rich Miller at the University of Michigan. Usually the scientist who picks the highest number gets his name in Time magazine. Won39。t new antiaging techniques keep us alive for centuries? Any cure, says Miller, for aging would probably keep most of us kicking until about 120. Researchers are working on treatments that lengthen the life span of mice by 50 percent at most. So, if the average human life span is about 80 years, says Miller, adding another 50 percent would get you to 120. So what can we conclude from this little disagreement among the researchers? That life span is flexible(有彈性的), but there is a limit, says George Martin of the University of Washington. We can get flies to live 50 percent longer, he says. But a fly39。s never going to live 150 years. Of course, if you became a new species (物種), one that ages at a slower speed, that would be a different story, he adds. Does Martin really believe that humans could evolve (進(jìn)化)their way to longer life? It39。s pretty cool to think about, he says with a smile.（1）What does the story of Jeanne Calment prove to us? can live to 122. people are creative. are sporty at 85. live longer than men.（2）According to Steve Austad at the University of Texas, ______. average human life span could be 110 cannot find ways to slow aging people can expect to live to over 150 are not sure how long people can live（3）Who would agree that a scientist will bee famous if he makes the wildest guess at longevity? Shay. Austad. Miller. Martin.（4）What can we infer from the last three paragraphs? of us could be good at sports even at 120. average human life span cannot be doubled. believe mice are aging at a slower speed than before. techniques could be used to change flies into a new species【答案】 （1）A（2）D（3）C（4）B 【解析】【分析】本文是一篇說(shuō)明文，介紹了科學(xué)家對(duì)長(zhǎng)壽的不同觀點(diǎn)和對(duì)延長(zhǎng)人的壽命的不同理解。 （1）考查細(xì)節(jié)理解。根據(jù)第二段中的“Jeanne Calment is the world39。s recordholder. She lived to the ripe old age of 122. ”說(shuō)明人們可以活到122歲，故選A。 （2）考查細(xì)節(jié)理解。文章第四段中 的“People can live much longer than we think.”可知人類(lèi)能活多長(zhǎng)仍是未知數(shù)，故選D。 （3）考查細(xì)節(jié)理解。根據(jù)第五段中的“Usually the scientist who picks the highest number gets his name in Time magazine.，可知Rich Miller認(rèn)為科學(xué)家們，只要瘋狂的想法找機(jī)會(huì)成名，因此選C。 （4）考查推理判斷。最后三段提到了在老鼠身上做的實(shí)驗(yàn)，證明生命是可以通過(guò)抗老技術(shù)延長(zhǎng)的，但同時(shí)又提到生命是有限度的?？茖W(xué)家通過(guò)試驗(yàn)證實(shí)人類(lèi)平均壽命的跨度不能翻倍，故選B。 【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，是一篇健康類(lèi)閱讀，考生需要準(zhǔn)確掌握細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。8．閱讀理解 Organic food (有機(jī)食品) is very popular. It is also expensive. Some organic food costs twice as much as non173。organic food. Some parents and pet owners pay up to 200 percent more for organic food while some people think organic food is a waste of money. There is one main difference between organic and nonorganic food. Organic farms do not use agricultural chemicals, such as pesticides (殺蟲(chóng)劑). This makes sure that the products are natural. Some people think organic means locally grown. At the beginning, this was true. Over time organic farming became more difficult. The demand for organic food grew larger than the supply. Small panies had to sell out to large panies. There weren39。t enough organic materials. This made it difficult for many organic panies to stay in business. Today, many large panies have an organic line of products. Is organic food more nutritious (有營(yíng)養(yǎng)的)? This is part of the debate. Many farmers and consumers (消費(fèi)者) believe it is. They think agricultural chemicals cause health problems, such as cancer. Many health experts disagree. Few studies prove that organic food prevents health problems. Health experts worry more about bacteria (細(xì)菌). These can e into contact with organic and non173。organic food. Doctors remend washing produce very carefully. Most people agree that naturally grown food tastes better. Is tastier food worth the extra money? This is a matter of opinion. Whether it is healthier or not may require more research. However, organic consumers argue it is better to be safe than sorry.（1）What is probably the major concern(關(guān)注) of organic food consumers? ....（2）What is the doctors39。 suggestion? your own food. the use of pesticides. sure the food is clean. large panies39。 products.（3）Which of the following do most people agree on organic food? tastes better. is easier to grow. contains more fat. is more nutritious.（4）Where does this text probably e from? health magazine. medical report. chemistry paper. menu of a restaurant.【答案】 （1）B（2）C（3）A（4）A 【解析】【分析】本文是一篇議論文，講述了人們?cè)谟袡C(jī)食物的價(jià)格，有機(jī)食物是否更有營(yíng)養(yǎng)等方面持有不同的觀點(diǎn)。 （1）考查推理判斷。根據(jù)最后一段中的“However, organic consumers argue it is better to be safe than sorry.”可知，有機(jī)食品消費(fèi)者們認(rèn)為安全總比后悔好，所以愿意為了安全花更多的錢(qián)。故選B。 （2）考查細(xì)節(jié)理解。根據(jù)第四段中的“Doctors remend washing produce very carefully.”可知，醫(yī)生建議要非常細(xì)心的清洗農(nóng)產(chǎn)品。故選C。 （3）考查細(xì)節(jié)理解。根據(jù)最后一段中的“Most people agree that naturally grown food tastes better.”可知，大多數(shù)人同意自然生長(zhǎng)的食物（即有機(jī)食品）味道更好。故選A。 （4）考查推理判斷?？v觀全文可知，本文介紹了有機(jī)食物的有關(guān)信息，并提到了人們對(duì)于其營(yíng)養(yǎng)，價(jià)格等方面的不同意見(jiàn)，屬于飲食、健康方面的文章。故選A。 【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，是一篇健康類(lèi)閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案。9．閱讀理解 I can39。t stop looking at my phone, but I39。m not alone.
