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.Some children have never seen a dentist before starting school.【单选题】

2、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 factors was ultimately responsible fｏｒthe fall of the civilization of ancient Egypt? 【单选题】

A.Change of climate.

B.Famine.

C.Flood.

D.Population growth.

正确答案:A

答案解析:A：气候的变化。第一段中有这样一个子句… a shift in climate… was ultimately to blame…最终须归咎于气候的变化。在第一题的题解中，我们提到了“饥荒”与“古埃及文明毁灭”的关系。但“饥荒”是表层的因素，“气候的变化”才是古埃及文明毁灭的深层的因素。因此A是正确的答案。B：饥荒。C：水灾。D：人口增长。

3、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. This is because too much padding can give buyers a false impression of what they are buying.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.

4、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.The authｏｒadmits that ____.【单选题】

A.baseball is too peaceful fｏｒthe young

B.baseball may seem boring when watched on TV

C.football is more attracting than baseball

D.baseball is more interesting than football

正确答案:B

答案解析:第三段指出，在电视上垒球运动被切换成不同角度的画面，而且不断地使用重放、特写等电视制作技术，这破坏了该运动的整体运动感，使观众无法将自己投入(project)到运动中去，以体会到这种寓动于静的运动之美。电视做不到这一点(The TV won\'t do it fｏｒyou)，电视上的垒球比赛看上去(seems)孤孤单单、冷冷清清、沉沉静静、慢慢腾腾。C、D不对，作者仅指出了不同运动有不同运动的特征，并未说哪种运动优于哪种。参阅文章最后一句。

5、Human Heart Can Make New CellsSolving a longstanding (为时甚久的) mystery, scientists have found that the human heart continues to generate new cardiac(心脏的 ) cells throughout the life span, although the rate of new cell production slows with age.The finding, published in the April 3 issue of Science, could open a new path fｏｒthe treatment of heart diseases such as heart failure ａｎｄ　heart attack, experts say."We find that the beating cells in the heart, cardiomyocytes (心肌细胞), are renewed," said lead researcher Dr. Jonas Frisen, a professｏｒof stem cell research at the Karolinska Institute in Stockholm, Sweden. "It has previously not been known whether we were limited to the cardiomyocytes we are born with ｏｒif they could be renewed," he said.The process of renewing these cells changes over time, Frisen added. In a 20 - year - old, about I percent of cardiomyocytes are exchanged each year, but the turnover (更替) rate decreases with age to only 0.45 percent by age 75."If we can understａｎｄ　how the generation of new cardiomyocytes is regulated, it may be potentially possible to develop pharmaceuticals (药物) that promote this process to stimulate regeneration after, fｏｒexample, a heart attack," Frisen said.That could lead to treatment that helps restore damaged hearts."A lot of people suffer from chronic heart failure," noted co - authｏｒDr. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said.With this finding, scientists are "opening the doｏｒto potential therapies (疗法) to having ourselves heal ourselves." Bhardwaj said. "Maybe one could devise a pharmaceutical agent that would make heart cells make new ａｎｄ　more cells to overcome the problem they are facing. "But barriers remain. According to Bhardwaj, scientists do not yet know how to increase heart cell production to a rate that would replace cells faster than they are dying off, especially in older patients with heart failure. In addition, the number of new cells the heart produces was estimated using healthy hearts-whether the rate of cell turnover in diseased hearts is the same remains unknown.The finding could prove to be useful to ______.【单选题】

A.the analysis of cardiac cells

B.the prevention of chronic diseases

C.the treatment of heart diseases

D.the study of longstanding mysteries
