Eating too much salty food when you39。re young can lead to health problems later. ”長(zhǎng)期以來(lái)，心臟病被認(rèn)為是成年人的問(wèn)題，但一項(xiàng)新的研究表明，鹽開(kāi)始影響兒童。年輕時(shí)吃太多咸的食物會(huì)導(dǎo)致以后的健康問(wèn)題；以及第三段中的“A kid with high blood pressure is more likely to bee a grownup with high blood pressure.”一個(gè)有高血壓的孩子更有可能成為一個(gè)有高血壓的成年人，可知，文章作者特別擔(dān)心孩子食用過(guò)咸的食物導(dǎo)致心臟病和高血壓。故選A。 （2）考查細(xì)節(jié)理解。根據(jù)第三段中的“Reducing salt might also help stop childhood obesity (肥胖). British researchers recently found that kids who eat less salt also drink fewer sugary soft drinks. ”減少鹽可能有助于阻止兒童長(zhǎng)胖。英國(guó)的研究人員最近發(fā)現(xiàn)吃鹽少的孩子喝的含糖飲料也更少，可知，作者認(rèn)為吃多鹽食品和喝過(guò)多含糖的軟飲料也會(huì)使孩子長(zhǎng)胖。故選C。 （3）考查細(xì)節(jié)理解。根據(jù)第四段中的“A recent study found that a growing number of kids in the US are suffering from kidney stones. This painful condition usually affects people aged over 40. Now, kids as young as five are getting it.”最近一項(xiàng)研究發(fā)現(xiàn)越來(lái)越多的美國(guó)孩子正在患腎結(jié)石。這種痛苦的病通常只在40歲以上的人才患，現(xiàn)在五歲的孩子也在遭受這種疾病，可知，研究發(fā)現(xiàn)現(xiàn)在腎結(jié)石這種病正在變得年輕化。故選B。 （4）考查主旨大意。根據(jù)第五段中的“The best way to reduce the amount of sodium you eat is to make changes gradually. Start by adding half as much salt to your dinner as you normally do. Switch to fresh foods instead of canned and bottled versions. And go easy on the condiments(調(diào)味品). You might also want to start reading nutrition labels. ”減少鈉攝入量的最好方法是逐漸改變。先在晚餐中加入平時(shí)一半的食鹽。食用新鮮食品而非罐裝或者瓶裝食品。少放些調(diào)味品。你可能也要閱讀營(yíng)養(yǎng)標(biāo)簽。可知，本段提供了一些可以減少食鹽攝入量的方法。故選B。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和主旨大意兩個(gè)題型的考查，是一篇健康類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，并根據(jù)上下文的邏輯關(guān)系，進(jìn)行概括和歸納，從而選出正確答案。8．閱讀理解 She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday. When it es to long life, Jeanne Calment is the world39。s recordholder. She lived to the ripe old age of 122. So is 122 the upper limit to the human life span(壽命)? If scientists e up with some sort of pill or diet that would slow aging, could we possibly make it to 150－or beyond? Researchers don39。t entirely agree on the answers. Calment lived to 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。科學(xué)家通過(guò)試驗(yàn)證實(shí)人類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。9．閱讀理解 In colleges around the country, most students are also workers. The reality of college can be pretty different from the images presented in movies and television. Instead of the students who wake up late, party all the time, and study only before exams, many colleges are full of students with pressing schedules of not just classes and activities, but real jobs, too. This isn39。t a temporary phenomenon. The share of working students has been on the rise since the 1970s, and onefifth of students work year round. About onequarter of those who work while attending school
