　　下面的短文后，列出了7个句子，请根据短文的内容对每个句子作出判断：如果该句提供的是正确信息，请选择A;如果该句提供的是错误信息，请选择B;如果该句的信息文中没有提及，请选择C。

　　The Speed Sound

　　Solids transmit (传递) sound very well. Try holding a wooden stick against part of a machine, and place your ears against the stick. The movement of the ball-bearing (滚珠轴承) can be clearly heard. This is a good way of finding the exact source of trouble in a motor-car engine which sounds as if it is wrong and yet gives no information of where the trouble is.

　　It is probably a good thing that sound cannot travel through a vacuum, for we are thus limited to earth-made sounds. The violent disturbances which are seen occasionally in the sun, for example, may affect our magnetism and our radio; they do not affect our ears, which is a very good thing for our peace of mind.

　　If we have used our eyes and ears, we may have realized that sound takes time to travel through the air. The sound of thunder nearly always follow the lightning flash although they happen at exactly the same time. And the appearance of white cloud above a distant ship or train tells us, before anything is heard, that its whistle has sounded. Just how fast does sound travel through the air?

　　The speed of sound in the air at ordinary temperature is about 1,100 feet per second, which is about one mile in five seconds or about 700 miles per hour. The speed of sound increases slightly with a rise in temperature and falls with a decrease in temperature. It is not affected by the pressure of the air.

　　16.“How Fast Sound Travels” can replace the original title of the passage.

　　A.Right

　　B.Wrong

　　C.Not Mentioned

　　17.We never hear anything that happens on the sun because of the distance between the earth and the sun.

　　A.Right

　　B.Wrong

　　C.Not Mentioned

　　18.The sound of thunder always follows the lightning flash because the sound of thunder travels more slowly through the air.

　　A.Right

　　B.Wrong

　　C.Not Mentioned

　　19.The research of sound is important to us.

　　A.Right

　　B.Wrong

　　C.Not Mentioned

　　20.The speed at which sound travel through the air at ordinary temperature is about 1,100 feet per minute.

　　A.Right

　　B.Wrong

　　C.Not Mentioned

　　21.Our eyes are keener than our ears.

　　A.Right

　　B.Wrong

　　C.Not Mentioned

　　22.The speed of sound increases with a rise in temperature.

　　A.Right

　　B.Wrong

　　C.Not Mentioned

　　Health Insurance

　　1 All insurance is a form of risk management. To deal with the unexpected risks to health through accident or illness, various types of health insurance programs have been devised. Health insurance is offered to individuals in two forms: individual plans and group plans. The insurers may be private companies or governments. Since the early 1970s another type of health-care coverage has become prominent: the health maintenance organization.

　　2 In some countries no insurance companies offer health care because governments have taken over the entire responsibility. The United States has a combination of private and government-sponsored insurance. Some government programs are limited to specific groups within the population.

　　3 The purpose of health insurance is to provide protection against loss of income and to cover the expenses of hospitalization and some of its associated costs. Some policies also help the people of disability and this will pay insured individuals should they be unable to work because of extended illnesses or permanent physical disability. Accident insurance covers sudden and unexpected injuries, while sickness insurance applies to illness or disease. There are policies that cover accidents only, while normal health insurance covers accidents as well as illness. Some policies are designed only to provide extra income during hospitalization. Many of these are known as mail-order policies, because they are sold to individuals who answer mailed requirement or reply to ads in newspapers and magazines or on television.

　　4 Health insurance covers a lot of costs. Some policies cover a stay in the hospital and services offered by the hospital. Surgical expense coverage provides benefits for surgery resulting from illness or accident. Beyond this, a policy may cover what are called regular medical expenses, including doctor’s fees, home nursing, diagnostic tests and ambulance service.

　　下面有3篇短文，每篇短文后有5道题。请根据短文内容，为每道题确定一个最佳选项。

　　第一篇

　　Insomnia

　　Insomnia is the inability to sleep restfully. It is a problem to nearly everyone at some time. A person may be awake for an hour in the middle of the night and then, next morning, feel that he hardly slept all night. Normally, worry about not getting enough sleep is the worst aspect of most insomnia. If insomnia occurs repeatedly, it is important to find its possible causes and try to correct them.

　　Any of large number of simple factors may make it difficult for someone to fall asleep. His mattress may be too soft or too hard. If there are too many blankets on a hot night, he may be too warm; if the mattress is too light he may feel cold during the night. The bedroom itself may be overheated or too cold. If it is not dark enough, or too noisy, this may cause difficulty in sleeping. Eating shortly before going to bed may also be responsible for insomnia. Drinks, such as tea or coffee, can also deep people awake.

　　Inability to fall asleep is sometimes a symptom of emotional or mental disorder.

　　The cause of insomnia may be easy to correct. The sufferer should check the mattress, and bedroom temperature, and make any necessary changes. He should relax for an hour or two before bedtime, perhaps by reading a book, watching television or taking a warm bath. If he wakes during the night he should try turning on the light and reading for a while. Take warm milk and a biscuit or two may be helpful. Above all, he should try not worry about sleeplessness --- when someone is tired enough he nearly always falls asleep.

　　A.a serious disease

　　A.eat anything during supper time

　　B.read any books before he goes to bed

　　C.watch television shortly before going to bed

　　D.drink anything that will keep him awake.

　　34.According to the passage, what is the worst aspect of insomnia?

　　A.Watching too much television

　　B.Eating too much before going to bed

　　Human Heart Can Make New Cells

　　Solving 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 ceils 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, 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.

　　36.The human heart stops producing cardiac cells

　　A.when a person is born.

　　B.when a person becomes old.

　　C.when a person gets sick.

　　D.when a person dies.

　　37.The finding could prove to be helpful to

　　A.the study of longstanding mysteries.

　　B.the analysis of cardiac cells.

　　C.the prevention of chronic diseases.

　　D.the treatment of heart disease.

　　38.The people who're in their mid-70s, only 0.45 percent of cardiomyocytes

　　A.are still functional

　　B.are replaced each year.

　　C.are lost each year.

　　D.are damaged each year.

　　39.Chronic heart failure is associated with

　　A.the death of heart cells.

　　B.the life span of a person.

　　C.the effects of pharmaceuticals.

　　D.the weight of the patient.

　　40.It remains unknown whether the rate of cell turnover in diseased hearts

　　A.changes over time.

　　B.can be monitored.

　　C.is the same as that in healthy hearts.

　　D.is high enough to replace cells faster than they're dying off.

　　Problems of Old Age

　　Mrs. White was 67 when she was moved out of the house where she had lived most of her life. The house was pulled down and a new block of fats was built there instead. At about the same time her only son was offered a job in Canada. Since the shopping and the housework had become too much for her, and her son and his wife were not able to look after her any more, Mrs. White had to be taken to Homefield Old People’s Home. She still had some friends near her old home, but now she was separated from them. During the first few months she was visited by friends and former neighbors, but Homefield was a long way from where they lived, too far away for old people.

　　At Homefield Mrs. White was given a small room of her own, and she was well looked after. But she knew no one when she arrived, and she was not able to make friends there. She was well liked by the people who worked there, but she kept apart from the other old people and spent most of her time in her room. After a time she was hardly ever seen at meetings and social evenings.

　　Although she was in poor health and had to be treated for a weak heart, she did not complain. “After all”, she said, “lots of people are worse off than I am.”

　　What she disliked most was the “quietness” in the home, and what even worse was that her son was not able to see her, not even at Christmas.

　　41.Mr. White was moved out of her old house mainly because

　　A.her son was going to work in Canada.

　　B.she didn’t want to do housework any more.

　　C.her house was to be replaced by a new building

　　D.her friends had all moved away from the area.

　　42.Why did her friends and neighbors stop seeing her after a few months?

　　A.Because they had to travel a long way to see her.

　　B.Because they had found some new friends.

　　C.Because they had fallen sick.

　　D.Because they had lost interest in the new place.

　　43.She was _____ the people who worked there.
