1、 Happiness If your sense of well-being fluctuates with stock market, you might be comforted to know that money can\'t buy you happiness anyway. In one American study conducted in 1993, level of income was shown to have an inverse relation to happiness: The group whose income had declined was happier overall than the group whose income had increased. A soon-to-be published review of the hundreds of studies on this subject supports the 1993 findings. In developed countries, the correlation between income and happiness is close to zero and sometimes negative. With a correlation between level of income and happiness somewhere between 0.12 and 0.18, the United States is near the bottom of the list; that factors other than income are overwhelmingly more important in explaining happiness. Also, as our material wealth increases, the gap between income and satisfaction with life seems to be widening. Predictably, money has its most positive effect on the poor, but once a person has achieved a minimal standard of living level of income has almost nothing to do with happiness. Close relationship, rather than money, is the key to happiness. Indeed, the number of one\'s personal friends is a much better indicator of overall satisfaction with life than personal wealth. One stands a better chance of achieving a satisfying life by spending time with friends and family than by striving for higher income. Incidentally, in the US, as people become richer, the probability of divorce increases. Our need for companionship is partly biological. All primates respond with pleasure to demonstrations of affection and with pain to loss of companionship. Isolated monkeys will sacrifice food just for the glimpses of another monkey. By ignoring our biologically programmed need for each other, we risk physical and mental distress. A recent cross-national study of mental depression in the US found that in advanced countries, there is a rising tide of major depression. Teenage suicides have increased in recent decades in almost all advanced countries. Moreover, in the US since World War Ⅱ, there has been an actual decline in the proportion of people who report themselves to be "very unhappy. " You can easily test the claim that companionship exceeds wealth as a source of happiness. Ask yourself which has a greater influence on your satisfaction with life: your income or the affection of your intimate companions and the well-being of your children? Conversely, which would make you more depressed: a reduction in salary or a divorce and isolation from your friends? Capitalism succeeds in creating material riches, but it is less successful in building companionable societies and protecting family integrity. But developing countries still have much work to do in pursuing material wealth, where a rise in productivity still greatly increases happiness. For poorer countries, the time is not yet ripe for a shift in priorities from wealth accumulation to companionship. Can we afford to believe that the pursuit of material gain will lead to self-fulfillment? We should continue to enjoy our wealth in good company, or else we may find that it is not satisfying. In the author\'s opinion, which of the following statements is not true?【单选题】

A. Wealth means differently to the poor and the rich.

B.Money makes the poor and the rich equally happy.

C.Money means less to a person as he achieves a higher standard of living.

D.Money means more to the poor than to the rich.

正确答案:B

答案解析: 被选项中多处提到了“富人”和“穷人”，因此利用the poor和the rich作为答案线索，这样在文章中找到了答案相关句： （第5段）Predictably，money has its most positive effect on the poor, but once a person achieved a minimal standard of living, level of income has almost nothing to do with happiness. 该句说“可以预言的是，钱对穷人有最大的影响”从该句内容可以推出这样的语意：钱对穷人和富人的影响是不同的。A：钱对穷人具有的意义比对富人更大；D：但是一旦人达到了最低生活水平，他的收入水平与快乐就几乎没有什么关系了。该部分内容与C一致（当一个人达到了更高一些的生活水平，钱对他来说所具有的意义就更小些），因此答案是B。

2、Musical Training Can Improve Communication Skills American scientists say musical training seems to improve communication skills and language retardation. They found that developing musical skills involves the same process in the brain as learning how to speak. The scientists believe that could help children with learning disabilities. Nina Kraus is a neurobiologist at Northwestern University in Illinois. She says musical training involves putting together different kinds of information, such as hearing music, looking at musical notes, touching an instrument and watching other musicians. This process is not much different from learning how to speak. Both involve different senses. She further explains musical training and learning to speak each make us think about what we are doing. She says speech and music pass through a structure of the nervous system called the brain stem. The brain stem controls our ability to hear. Until recently, experts have thought the brain stem could not be developed or changed. But Professor Kranss and her team found that musical training can improve a person\'s brain stem activity. The study involved individuals with different levels of musical ability. They were asked to wear an electrical device that measures brain activity. The individuals wore the electrode while they watched a video of someone speaking and a person playing a musical instrument ---- the cello. Professor Krauss says cellos have sound qualities similar to some of the sounds that are important with speech. The study found that the more years of training people had, the more sensitive they were to the sound and rhythm of the music. Those who were involved in musical activities were the same people in whom the improvement of sensory events was the strongest. ____ She says using music to improve listening skills could mean they hear sentences and understand facial expressions better. 【单选题】

3、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 for children 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, a group of 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。

6、The Ideal HusbandScience now might be able to explain women\'s fascination with Brad Pitt\'s face and George Clooney\'s eyes. Women seem to judge potential mate by how masculine their features are, new research shows. Men with square jaws and well-defined brow ridges are seen as good short-term partners, while those with more feminine traits such as a rounder face and fuller lips are perceived as better long-term mates.In the study by Daniel Kruger at the US\'s University of Michigan, 854 subjects viewed a series of male head shots that had been digitally changed to exaggerate or minimize masculine traits. They then . answered questions about how they expected the men in the photos to behave.Most participants said that those with more masculine features were likely to be risky, competitive, and more apt to fight, challenge bosses, cheat on spouses and put less effort into parenting. Those with more feminine faces were seen as good parents and husbands, hard workers and emotionally supportive mates.But, despite all the negative characteristics, when asked who they would choose for a short-term relationship, women selected the more masculine looking men. Brad and George, both chiseled jaws and well-defined brows, then would be good for a brief romance, not for something longer.The study was published in the December issue of the US journal Personal Relationships.Kruger said that from an evolutionary perspective, this makes sense. The key is testosterone, the hormone responsible ____ the development of masculine facial features and other sexual characteristics. It has been found to affect the body\'s ability to fight disease: men with high levels of the hormone are typically strong and healthy- traits women want to pass on to their children.However, increased testosterone has also been linked to cheating and violence in relationships. So, these men might produce high quality offspring, but they don\'t always make great parents or faithful mates, Kruger says.The scientific community have shown skepticism toward physiognomy, which links facial characteristics to certain behavioral traits. But Kruger argues that the research is a valuable tool for understanding mating strategies. And, of course, for explaining why Tony Leung and Takeshi Kanesshiro have millions of female fans. It might have to do with their genes. Or something to do with ours.【单选题】

A.of

B.at

C.for

D.in

正确答案:C

答案解析:这四个都是介词。responsible后面跟for。

7、Outside-the-classroom Learning Makes a Big DifferencePutting a bunch of college students in charge of a $300,000 Dance Marathon, fundraiser surely sounds a bit risky. When you consider the fact that the money is supposed to be given to. Children in need of medical care, you might call the idea crazy.Most student leaders don\'t want to spend a large amount of time on something they care little about, said 22-year-old University of Florida student Darren Heitner. He was the Dance Marathon\'s operations officer for two years.Yvonne Fangmeyer, director of the student organization office at the University of Wisconsin, conducted a survey in February of students involved in campus organizations. She said the desire for friendship was the most frequently cited reason for joining.At large universities like Fangmeyer\'s, which has more than 40,000 students, the students, first of all, want to find a way to "belong in their own comer of campus".Katie Rowley, a Wisconsin senior, confirms the survey\'s findings. "I wanted to make the campus feel smaller by joining an organization where I could not only get involved on campus but also find a group of friends. "All of this talk of friendship, however, does not mean that students aren\'t thinking about their resumes. "I think that a lot of people do join to \'fatten up their resume\'," said Heitner. "At the beginning of my college career, I joined a few of these organizations, hoping to get a start in my leadership roles. "But without passion student leaders can have a difficult time trying to weather the storms that come. For example, in April, several student organizations at Wisconsin teamed up for an event designed to educate students about homelessness and poverty. Student leaders had to face the problem of solving disagreements, moving the event because of rainy weather, and dealing with the university\'s complicated bureaucracy."Outside-of the classroom learning really makes a big difference," Fangmeyer said.Who is Katie Rowley?【单选题】

A.She\'s a senior professor.

B.She\'s a senior student.

C.She\'s a senior official.

D.She\'s a senior citizen

正确答案:B

答案解析:文章提到了好几个人，Katie Rowley是其中的一个，第五段讲到了Katie Rowley。a Wisconsin senior是“威斯康星四年级学生”。

8、The two banks have announced plans to merge next year.【单选题】

9、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 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。

10、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" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size for size, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals. 4 The Permian extinction, for example, 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, director of 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 for thousands or millions 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 or sulphur 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 for the 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”for these 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。
