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. Which of the following statements best describes the situation in the US, according to the 1993 study? 【单选题】

A.Most people think personal wealth can make them happy.

B.Most people do not think wealth has much to do with happiness.

C.Money is an important factor in making one happy.

D.Happiness can only be explained in terms of income.

2、Happy Marriage, Happy HeartHappily married people have lower blood pressure ____ unhappily married people or singles, a Brigham Young University study says.On the other hand, even having a supportive social network did not translate into a blood pressure benefit for singles or unhappily married people, according to the study."There seems to be some unique health benefits from marriage. It\'s not just being named that benefits health-what\'s really the most protective of health is having a happy marriage," study author Julianne Holt Lunstad, a psychologist who specializes in relationships and health, said in a prepared statement.The study included 204 married and 99 single adults who wore portable blood - pressure monitors for 24 hours. The monitors recorded blood pressure at random intervals and provided a total of about 72 readings."We wanted to capture participants\' blood pressure doing whatever they normally do in everyday life. Getting one or two readings in a clinic is not really representative of the fluctuations (波动) that occur throughout the day," Holt Lunstad said.Overall, happily married people scored four points lower on the blood pressure readings than single adults. The study also found that blood pressure among married people, especially those in happy marriages dropped more during sleep than in single people."Research has shown that people whose blood pressure remains high throughout the night are at much greater risk of heart disease than people whose blood pressure drops," Holt Lunstad said.The study was published in the March 20 issue of the journal Annals (年刊) of Behavioral Medicine.The study also found that unhappily married adults have higher blood pressure than both happily married and single adults.Holt Lunstad noted that married couples can encourage healthy habits in one another, such as eating a healthy diet and having regular doctor visits. People in happy marriages also have a source of emotional support, she said. 【单选题】

3、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 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 (心肌细胞), 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 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, 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, 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 (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.In people in their mid -70s, only 0. 45 percent of cardiomyocytes ______.【单选题】

A.are still functional

4、Parkinson\'s Disease1. Parkinson\'s disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Normally, these nerve cells make an important chemical called dopamine(多巴胺). Dopamine sends signals to the part of your brain that controls movement. It lets your muscles move smoothly and do what you want them to do. When you have Parkinson\'s, these nerve cells break down. Then you no longer have enough dopamine, and you have trouble moving the way you want to.2. No one knows for sure what makes these nerve cells break down. But scientists are doing a lot of research to look for the answer. They are studying many possible causes, including aging and poisons in the environment. Abnormal genes seem to lead to Parkinson\'s disease in some people. But so far, there is not enough proof to show that it is always inherited.3. Tremor (颤抖) may be the first symptom you notice. It is one of the most common signs of the disease, although not everyone has it. Tremor often starts in just one arm or leg or only on one side of the body. It may be worse when you are awake but not moving the affected arm or leg. It may get better when you move the limb or you are asleep. In time, Parkinson\'s affects muscles all through your body, so it can lead to problems like trouble swallowing or constipation(便秘) . In the later stages of the disease, a person with Parkinson\'s may have a fixed or blank expression, trouble speaking, and other problems. Some people also have a decrease in mental skills.4. At this time, there is no cure for Parkinson\'s disease. But there are several types of medicines that can control the symptoms and make the disease easier to live with. You may not even need treatment if your symptoms are not obvious. Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctor will adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.Paragraph 3 ______【单选题】

A.Tips for Patients with the Disease

B.Common Treatment for the Disease

C.Means of Diagnosis of the Disease

5、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】
