1、Importance of Children\'s Oral HealthFebruary is National Children\'s Dental(牙齿的) Health Month, but in children good oral(口部的) care is critical every day. The first comprehensive study on the nation\'s oral health, released recently by the Office of the U. S. Surgeon General, calls dental ａｎｄ　oral diseases a "silent epidemic (流行病)", even in children. The report states that more than 51 million school hours are lost each year to dental - related illness. In fact, a recent study pointed to dental care as the most common unmet health need among American children.To help counter this, the American Academy of Periodontology (牙周病学) (AAP) is launching an effort to educate children ａｎｄ　parents about the prevention of dental diseases in children."This is important because oral problems can impact self - esteem fｏｒchildren ａｎｄ　lead to problems of eating, speaking ａｎｄ　attending to learning," said Michael McGuire, president of the AAP.Common dental problems seen in children are cavities (龋洞) ａｎｄ　gingivitis (龈炎), which are found in the majority of U. S. children. "When these problems are not caught early ａｎｄ　treated, they can develop into more severe problems ａｎｄ　cause unnecessary suffering," said McGuire. "However, much of the time, oral problems are avoidable problems."In the Rio Grande Valley in Texas, aｇｒｏｕｐof more than 120 dentists(牙医) volunteers to deliver dental care to thousands of low - income children each year with its Mobile Dental Unit that travels from school to school."According to the Surgeon General\'s Report, about 37 percent of children have not had a dental visit before starting school," said McGuire. When children don\'t see dentists, they miss the opportunity to have problems caught early before they develop into larger, more expensive problems to treat, ａｎｄ　parents miss the opportunity to learn how to promote good oral habits in their children.Oral problems in children can develop into more severe problems.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题难度不大，答案依据比较明显，带者题干信息词回文章定位，答案依据在文章第四段第二句：When these problems are not caught early ａｎｄ　treated，they can develop into more severe problem ａｎｄ　cause unnecessary suffering谈到这些问题如果没能及早发现和治疗，会发展成更严重的问题，所以本题和原文句意相符，答案是A。

4、TV Games Shows One of the most fascinating things about television is the size of the audience. A novel can be on the "best sellers" list with a sale of fewer than 100,000 copies, but a popular TV show might have 70 million TV viewers. TV can make anything ｏｒanyone well known overnight. This is the principle behind "quiz" ｏｒ"game" shows, which put ordinary people on TV to play a game fｏｒthe prize ａｎｄ　money. A quiz show can make anyone a star, ａｎｄ　it can give away thousands of dollars just fｏｒfun. But all of this money can create problems. Fｏｒinstance, in the 1950s, quiz shows were very popular in the U. S. ａｎｄ　almost everyone watched them. Charles Van Doren, an English instructor, became rich ａｎｄ　famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show\'s producers, who were pulling the strings, gave the answers to the most popular contestants beforehand. Why? Because if the audience didn\'t like the person who won the game, they turned the show off. Based on his story, a movie under the title " Quiz Show" is on 40 years later. Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren\'t taken as seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, ｏｒthat try to cause newly-married couples to fight on TV, ｏｒthat punish losers by humiliating them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions. The principle behind "quiz" ｏｒ"game" shows is to put ordinary people on TV to play a game fｏｒprizes ａｎｄ　money. 【单选题】

A. Right

B. Wrong

C.Not mentioned

正确答案:B

答案解析:该句是说“猜谜节目背后的原则是为了让普通人参加赢取奖品和奖金的电视节目”。答案查找的线索词： ordinary people（普通人）。从第二段开始查找（因为问题一的答案在第一句的结尾），不难在第二段的第一句中找到含有ordinary people的相关句。对照原句和问题句，不难发现原句的结构与问题句的结构有所不同：原句中有代词this，说“这就是猜谜节目背后的原则”，而代词往往指代前一句的内容，可见TV can make anything ｏｒanyone well-known overnight. 才是猜谜节目背后的原则。所以该句说法错误。

5、Blasts from the Past1 Volcanoes were more destructive in ancient history. Not because they were bigger, but because the carbon they released wiped out life with greater ease.2 Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions ａｎｄ　mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over the past 300. million years coincided with huge formations of volcanic rock. To his surprise, the older the massive volcanic eruptions were, the more damage they seemed to do.3 Wignall calculated the "killing efficiency" fｏｒthese volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size fｏｒsize, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.4 The Permian extinction, fｏｒexample, which happened 250 million years ago, is marked by floods of volcanic rock in. Siberia that cover an area roughly the size of western Europe, Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide, The global warming that followed wiped out 8 per cent of all marine genera at the time, ａｎｄ　it took 5 million years far tire planet to recover.5 Yet 60 million years ago in the late Palaeocene there was another huge amount of volcanic activity ａｎｄ　global-warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years, "The most recent ones hardly have an effect at all," Wignall says. He ignored the extinction which wiped out the dinosaurs at the end of the Cretaceous, 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid.6 Wignall thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of C02 Ocean chemistry may also have played a role. As the supercontinents broke up ａｎｄ　exposed more coastline there may have been more weathering of silica rocks. This would have encouraged the growth of phytoplankton in the oceans, increasing the amount of C02 absorbed from the atmosphere.7 Vincent Courtillot, directｏｒof the Paris Geophysical Institute in France, says that Wignall\'s idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they fasted. ａｎｄ　it is impossible to tell whether the huge blasts lasted fｏｒthousands ｏｒmillions of years.8 Courtillot also adds that it is difficult to estimate how much lava prehistoric volcanoes produced, ａｎｄ　that lava volume may not necessarily correspond to carbon dioxide ｏｒsulphur dioxide emissions.Courtillot rejects____.【单选题】

A.than more recent ones

B.the killing efficiency fｏｒolder eruptions

C.has remained controversial

D.Wignall\'s calculations as acceptable

E.has been mown to us all

F.his ideas

正确答案:D

答案解析:Wignall\'s calculations as acceptable合成后的句子是：Courtillot rejects Wignall\'s calculations as acceptable. Courtillot拒绝接受Wignall的计算。答案可以从最后两段中找到。
