1、Driving after drinkingThe legal limit for driving after drinking alcohol is 80 milligrams of alcohol in 100 millilitres of blood, when tested. But there is no sure way of telling how much you can drink before you reach this limit. It varies with each person depending on your weight, your sex, what you\'ve just eaten and what sort of drinks you\'ve had. Some people might reach their limit after only about three standard drinks.In fact, your driving ability can be affected by just one or two drinks. Even if you\'re below the legal limit, you could still be taken to court if a police officer thinks your driving has been affected by alcohol.It takes about an hour for the body to get rid of the alcohol in one standard drink. So, if you have a heavy drinking in the evening you might find that your driving ability is still affected the next morning, or you could even find that you\'re still over the legal limit. In addition, if you\'ve had a few drinks at lunchtime, another one or two drinks in the early evening may well put you over the legal limit.In a test with professional drivers, the more alcoholic drinks they had had, the more certain they were that they could drive a test course through a set of movable posts…and the less able they were to do it! So the only way to be sure you\'re safe is not to drink at all.Alcohol is a major cause of road traffic accidents. One in three of the drivers killed in road accidents have levels of alcohol which are over the legal limit, and road accidents after drinking are the biggest cause of death among young men. More than half of the people stopped by the police to take a breath test have a blood alcohol concentration of more than twice the legal limit.It is important to remember that driving after you\'ve been drinking doesn\'t just affect you. If you\'re involved in an accident it affects a lot of other people as well, not least the person you might kill or injure.A test showed that drunken professional drivers could____.【单选题】

A.have greater confidence than sober ones

B.move away a set of posts on the test ground

C.fail in the test despite their self-affirmation

D.serve as alarming examples to potential drivers

正确答案:C

答案解析:细节考查题。根据题干定位原文，答案参见第四段：在一次对专职驾驶员的测试中，他们酒喝得越多，就越肯定自己能在测试课程中过关，但通过的可能性越小。故选项C“尽管自信也不能通过测试”正确。

2、Human Heart Can Make New CellsSolving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac 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 for the treatment of heart diseases such as heart failure and heart attack, experts say. "We find that the beating cells in the heart, cardiomyocytes, are renewed," said lead researcher Dr. Jonas Frisen, a professor of 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 or if they could be renewed," he said. The process of renewing these cells changes over time, Frisen added. In a 20-year-old, about 1 percent of cardiomyocytes are exchanged each year, but the turnover 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 that promote this process to stimulate regeneration after for example, 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-author Dr. Ratan Bhardwaj. Ratan Bhardwaj, also from the Karolinska Institute. "Chronic heart failure arises from heart cells dying," he said. With this finding, scientists are "opening the door to potential therapies 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.In people in their mid-70s, only 0.45 percent of cardiomyocytes ____.【单选题】

A.are still functional

B.are reduced each year

C.are replaced each year

D.are damaged each year

正确答案:C

答案解析:第四段说，一个人20岁时，其每年被更替的心肌细胞为1%，随着年龄的增长，该更替率( turnover rate)不断下降，等到75岁时，只有0. 45%。

3、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 or worse 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 for the 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 for the 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。

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 or even 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 for involvement. The TV won\'t do it for you.Take, for example, 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 or bring the glove to a point in front of him, takes a step right or left, backward or forward, 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.Those who don\'t like baseball may complain that ____.【单选题】

A.it is only to the taste of the old

B.it involves fewer players than football

C.it is not exciting enough

D.it is pretentious and looks funny

正确答案:C

答案解析:文章第一段指出：许多人不喜欢垒球，一提起垒球这些人就打哈欠甚至皱眉头。对他们来说，看垒球意味着眼巴巴地观望着身着运动装(outfit)的人呆立在球场上，东瞧瞧西望望，很少有什么（激动人心的）事发生，没意思透了。他们认为这样的运动更适合上个世纪的人的口味，不像橄榄球那样充满活力。A:它只适合老年人的口味。注意：说的是适合上个世纪的人的口味，意味不一样。D：矫揉造作、滑稽可笑。这与说它gentlemanly（具有绅士风度、矜持，没有冲撞或拼抢）不一样。

5、College Night Owls Have Lower GradesCollege students who are morning people tend to get better grades than those who are night owls(晚睡的人), according to University of North Texas researchers.They had 824 undergraduate(大学本科生的) students complete a health survey that in cluded questions about sleep habits and daytime functioning, and found that students who are morning people had higher grade point averages(GPAs) than those who are night people."The finding that college students who are evening types have lower GPAs is a very important finding, sure to make its way into undergraduate psychology texts in the near future, along with the research showing that memory is improved by sleep," study co - author Daniet J. Taylor said in a prepared statement."Further, these results suggest that it might be possible to improve academic performance by using chronotherapy (时间疗法) to help students retrain their biological clock to become more morning types," Taylor said.The research was expected to be presented Monday at SLEEP, the annual meeting of the Associated Professional (专业的) Sleep Societies, in Baltimore.In other findings expected to be heard at the meeting, University of Colorado researchers found a significant association between insomnia (失眠) and a decline in college students\' academic performance.The study included 64 psychology, nursing and medical students, average age 27. 4 years, who were divided into two groups—low GPAs and high GPAs.Among those with low GPAs,69.7 percent had trouble falling asleep,53.1 percent experienced leg kicks or twitches (痉挛) at night, 65.6 percent reported waking at night and having trouble falling back to sleep, and 72.7 percent had difficulty concentrating during the day."In college students, the complaint of difficulty concentrating during the day continues to have a considerable impact on their ability to succeed in the classroom," study author Dr. James F. Pagel said in a prepared statement. "This study showed that disordered sleep has significant harmful effects on a student\'s academic performance, including GPAs."Mr. Taylor believed that the finding of their study would soon ______.【单选题】

A.be criticized by psychology students

B.be confirmed by psychological studies

C.be included in undergraduate psychology texts

D.become the most popular psychology text

正确答案:C

答案解析:本题难度不大，答案依据比较明显，答案依据是文章第三段第一句，谈到研究结果一定会在不久将来被收录到本科心理学教材中，回来看选项，C项和原文句意相符，是答案。
