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.The low - income children are very grateful to the dentists.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:C
答案解析:本题有一定难度,需要通读全文,吃透原文句意。主要答案依据在文章第五段:…agroupof more than 120 dentists volunteers to deliver dental care to thousands of low - income children each year,谈到志愿者每年给几千个低收入家庭的孩子治疗牙病,但没有提到孩子感激志愿者的问题,因此本题未提及,答案是C。
2、BaseballThere are people in Italy who can\'t stand soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who yawn oreven frown when somebody mentions baseball. Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens. They tell you it\'s a game better suited to the 19th century, slow, quiet and gentlemanly. These are the same people you may be one of them who love football because there\'s the sport that glorifies "the hit".By contrast, baseball seems abstract, cool, silent and still. On TV the game is fractured into a dozen perspectives, replays and close ups. The geometry of the game, however, is essential to understanding it. You will contemplate the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the game affords so much space and time forinvolvement. The TV won\'t do it foryou.Take, forexample, the third baseman. You sit behind the third base dugout and you watch him watching home plate. His legs are apart, knees flexed. His arms hang loose. He does a lot of this. The skeptic still cannot think of any other sports so still, so passive. But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms orbring the glove to a point in front of him, takes a step right orleft, backward orforward, perhaps he glances across the field to check his first baseman\'s position. Suppose the pitch is a ball. "Nothing happened," you say. "I could have had my eyes closed".The skeptic and the innocent must play the game. and this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of horsehide on wood if football is a symphony of movement and theatre, baseball is chamber music, a spacious interlocking of notes, chores and responses.By stating "I could have had my eyes closed" the authormeans ____.【单选题】
A.The third baseman would rather sleep than play the game.
B.Even if the third baseman closed his eyes a moment ago, it could make no different to the result.
C.The third baseman is so good at baseball that he could finish the game with eyes closed all the time and do his work well.
D.The consequent was too bad he could not bear to see it.
正确答案:B
答案解析:第四段整个都在描述垒球场上的一个场景: 拿三垒的运动员假设对方全投出好球,做好了一切准备,但是对方投出的并不是好球。所以在那时候他的准备做不做都不会影响比赛结果。他说本来可以闭上眼睛,意思就是B项所写的。A、C、D都不符合作者的意图。这道题需要完整地了解第四段内容才能作好选择。
3、Blasts from the Past 1 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. Paragraph 3____ 【单选题】
A.Killing Power of Ancient Volcanic Eruptions
B.Association of Mass Extinction with Volcanic Eruption
C.Calculation of the Killing Power of Older Eruptions
D.A Mass Extinction
E.Volcanic Eruptions That Caused No Mass Extinction
F.ccounting forthe Killing Power of Older Eruptions
正确答案:C
答案解析:第三段的第一句话是这么说的:Wignall calculated the“killing efficiency”forthese valcanoes wignall计算了这些火山的“灭种效率”。killing power与killing efficiency意思差不多。killing power:灭种力。
4、Reduce PackagingPressure increased recently on British supermarkets and retailers to reduce packaging as part of an anti - waste campaign. The campaign was initiated by The Independent newspaper. Britain generates 4.6 million tons of household waste every year by packaging.Dozens of people have expressed anger at the excess of plastic wrapping. Campaigners have called on Britain to learn from other European countries, In Belgium, when you buy something in a plastic orglass container, you make a deposit. When returned bottles are put in a vending machine 自动售货机, the deposit is refunded. Environmentalists warn that Britain lags behind in this.There were reports of growing unease among consumers over the amount of packaging they have to deal with. Trade standards officers also object to excessive packaging. ____In response to a campaign by Britain\'s The Independent newspaper, leading supermarkets have pointed to various initiatives to win the public confidence. tons of cardboard a year by switching to reusable plastic crates 装货箱 fortransporting its fresh produce.But campaigners said retailers and the government could learn much from anti - waste practices on the Continent. In Sweden, non - recyclable batteries have been taxed since 1991 to encourage a switch to alternatives. This has resulted in a 74 percent reduction in sales. In Germany, plastic bags are unheard of in supermarkets and deposits are paid forreusable plastic and glass beverage bottles.【单选题】
A.If a product is over packaged, don\'t buy it.
B.In Belgium, when you buy something in a plastic orglass container, you make a deposit.
C.This is because too much padding can give buyers a false impression of what they are buying.
D.This has resulted in a 74 percent reduction in sales.
E.Tesco said it was saving 112,000 tons of cardboard a year by switching to reusable plastic crates (装货箱) fortransporting its fresh produce.
F.The campaign was initiated by The Independent newspaper.
正确答案:C
答案解析:本题有一定难度。要认真阅读文章,理解好句意,判断出叙述逻辑,可使用排除法和代入法。本题的上句谈到了贸易标准部门的官员反对过度的包装,由此可以推断此处应该进行解释,回来看选项,可以发现C项合适,把C项代入文中,符合上下文逻辑,是答案。
5、Egypt Felled by Famine Even ancient Egypt\'s mighty pyramid builders were powerless in the face of the famine that helped bring down their civilization around 2180 BC. Now evidence gleaned from mud deposited by the River Nile suggests that a shift in climate thousands of kilometers to the south was ultimately to blame and the same orworse could happen today. The ancient Egyptians depended on the Nile\'s annual floods to irrigate their crops. But any change in climate that pushed the African monsoons southwards out of Ethiopia would have diminished these floods. Dwindling rains in the Ethiopian highlands would have meant fewer plants to stablize the soil. When rain did fall it would have washed large amounts of soil into the Blue Nile and into Egypt, along with sediment from the White Nile. The Blue Nile mud has a different isotope signature from that of the White Nile. So by analyzing isotope differences in mud deposited in the Nile Delta, Michael Krom of Leeds University worked out what proportion of sediment came from each branch of the river. Krom reasons that during periods of drought, the amount of the Blue Nile mud in the river would be relatively high. He found that one of these periods, from 4,500 to 4,200 years ago, immediately predates the fall of the Egypt\'s Old Kingdom. The weakened waters would have been catastrophic forthe Egyptians. " Changes that affect food supply don\'t have to be very large to have a ripple effect in societies," says Bill Ryan of the Lamont Doberty Earth Observatory in New York. "Similar events today could be even more devastating," says team member Daniel Stanley, a geoarchaeologist from the Smithsonian Institution in Washington, D C. " Anything humans do to shift the climate belts would have an even worse effect along the Nile system today because the populations have increased dramatically. " Which of the following statements is true? 【单选题】
A.The White Nile is the trunk of the River Nile.
B.The White Nile is the trunk of the Blue Nile.
C.The White Nile is a branch of the Blue Nile.
D.The White Nile and the Blue Nile are branches of the River Nile.
正确答案:D
答案解析: D说的是:青尼罗河和白尼罗河是尼罗河的支流。第四段中的最后一句话是这么说的:… worked out what proportion of sediment came from each branch of the river. 这里的“河”是指“尼罗河”,“每条支流”是指上文所说的“青尼罗河”和“白尼罗河”。因此,D是正确的答案。A:白尼罗河是尼罗河的干流。B:白尼罗河是青尼罗河的干流。C:白尼罗河是青尼罗河的支流。显然,这些都不是答案。
