听力原文：Ten years ago a small boy fell off his bicycle because he wanted to look behind.

听力原文： Ten years ago a small boy fell off his bicycle because he wanted to look behind. This gave Billy Morgan, a British businessman, a new idea. He designed a bicycle helmet with a built-in minor.

Mr. Morgan launched the product six months ago, and it now has sales of 27,000 and sells in twelve countries from Korea to Finland. The target for the second year is for sales of nearly 1 million pounds.

But it wasn't easy for Mr. Morgan to become successful. He had problems when he tried to interest UK manufacturers in making the helmet. It cost Mr. Morgan 1 million pounds of his own money to develop the helmet for the mass market.

Mr. Morgan found a helmet-maker in France. He worked with French consultants to make the design better for mass production, and spent ￡ 450,000 on preparing the French plant to make the helmet.

Now he plans to do more research and development. He wants to manufacture other designs of rearview helmets for motorcycling, skiing and horse-riding.

(34)

A．A product launch that didn't succeed.

B．A new idea that became a commercial success.

C．A manufacturing problem.

D．A new design of the bicycle helmet.

听力原文：Some mental health research has linked depression in women with lower weight in t

听力原文： Some mental health research has linked depression in women with lower weight in their babies during the first year of life. They studied 632 women from small villages. The women were in good physical health and in the last three months of pregnancy.

The study identified 160 of the women, or one in four, as depressed. They always felt sad or tired. They had problems eating or sleeping. They felt guilty and thought about killing themselves.

The researchers compared these women with 160 others who were not depressed. Health workers then weighed and measured the babies of both groups at birth. Re-examinations took place at two, six and twelve months of age. The health workers also re-examined the mental health of the mothers.

Babies whose mothers remained depressed grew less than the babies of the other women. The babies of the depressed mothers were also more likely to get sick. Earlier studies showed that ten to fifteen percent of pregnant women and new mothers in Western nations suffer from depression. Other studies in South Asia have found that depression affects almost two times as many women in developing countries.

A new program will be started to help these new mothers. In the program health workers will visit new mothers for up to a year. The workers offer advice about things like health and cleanliness. The health workers will also listen to the mother's problems and suggest some easy things at first that she can do for her baby. The program will be tested for three years to see how well it succeeds.

(23)

A．How depression affects women's health.

B．How depression in mothers affects their babies' weight.

C．How to get rid of depression.

D．How to better feed low weight babies.

听力原文： Today we're going to talk about shyness and discuss recent research on ways to help children learn to get along with others socially.

Many people consider themselves shy. In fact, forty percent of people who took part in our survey said they were shy--that's two out of every five people. And there are studies to indicate that the tendency toward shyness may be inherited. But certain timid children doesn't mean that they are bound to be shy forever. There is something parents, teachers, and the children themselves can do to overcome this tendency--and even to prevent it.

Our researchers found that if parents gently push their shy children to try new things, they can help these children become less afraid and less inhibited. Another way to help shy children is to train them in social skills. For example, there are special training programs where children are taught things like looking at other children while talking to them, talking about others' interests, and even smiling.

These groups have been very successful in giving shy children a place to feel safe and accepted, and building up their self-esteem.

(33)

A．Showing children how to behave.

B．Helping children overcome shyness.

C．Several causes of children's shyness.

D．How timid children become shy adults.

听力原文： The Human Genome Project, a great $ 3 billion, 15-year task aimed at drawing the genetic map of humans, is now more than 90 percent complete. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging human life. But those communities and policy makers are also careful about the scientific door they are opening as the project uncovers the mysteries of life.

For the last few years, the genetic advances in the fast developing field of biotechnology have provided materials for all kinds of work, but the developments of modern science in unlocking the secrets of human genetic code have opened a world of possibilities for human health, as well as for the population imagination.

While European and Japanese researchers are making rapid progress in decoding human DNA, the leading organization for genetic research in the Untied States, which began in 1990, is "unlocking the code" of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with as yet terrible diseases, and making progress toward separating the genes that show a sign of breast cancer or AIDS.

Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome; as they expect to develop a lot of new drugs for these illnesses.

Why did the scientists work so hard at mapping the human genome？

A．Because the human genome can destroy many illnesses.

B．Because the human genome's completion can help to get rid of many diseases.

C．Because they wanted to be better known than others.

D．Because the Human Genome Project can provide a lot of chances of work.

听力原文：As is known to all, scientists and philosophers had studied the human body and it

听力原文： As is known to all, scientists and philosophers had studied the human body and its functions from very early times. Unfortunately, many of the ideas and theories, correct and incorrect, were accepted without question for a great number of years. But by the 16th century, knowledge gained through chemical experiments was beginning to make some people think more deeply about how the human body works.

A most important medical discovery was made by William Harvey in 1628. He found out that the blood is circulated round the body in one direction only by the pumping action of the heart. It had previously been incorrectly thought that the blood moved with a backward and forward motion.

Early in the 17th century a new instrument came into use that was to open up a whole new area in the study of medical and scientific matters. This was the microscope.

The first instruments were not very efficient. They were able to magnify only a very small part of the object and this was always surrounded by rings of colored light. Nevertheless a great step forward had been taken which was of vital importance for future research and development.

(30)

A．Scientists and philosophers had never studied the human body and its functions.

B．Many of the ideas and theories that people used to accept were all incorrect.

C．People used to accept ideas and theories.

D．People used to accept undoubtedly many of the ideas and theories, correct and incorrect.

听力原文：Rats are the enemy of human beings. They eat or spoil crops of grain and rice bef

听力原文： Rats are the enemy of human beings. They eat or spoil crops of grain and rice before they can be harvested, or while they are in storage. In India, where millions of people go hungry, there are ten times as many rats as people. Rats devour half of the available food. Rats will also attack birds and animals, from frogs and chicks to geese and young calves. They have even destroyed dams and buildings by making holes through or under them, and have started fires by chewing on electrical wiring.

The most terrible destruction caused by rats, however, has come from the diseases they carry. In the fourteenth century, rats caused the death of one-third of the world's population by transmitting the dreadful Black Plague that mined Europe.

Ironically, it is in fighting diseases that rats have been most useful to humanity. Thousands of specially bred rats are used in research laboratories every year to test medicines which can possibly be used to prolong and improve human life. Some laboratory rats are even used to test new methods of eliminating their cousins, the wild rats.

(23)

A．The Black Plague.

B．Enemy of Humanity.

C．Common Animal pests.

D．Causes of World Hunger.

听力原文：Most people think that the older you get, the harder it is to learn, a new langua

听力原文： Most people think that the older you get, the harder it is to learn, a new language. That is, they believe that children can learn more easily and efficiently than adults. Thus, at some point in our lives, maybe around age 12 or 13, we lose the ability to learn languages well. Is this idea a fact or myth？

Is it true that children can learn a foreign language more efficiently than adults？ On the contrary, research studies suggest that the opposite may be true. One report, on 2,000 Danish children studying Swedish, concluded that the teenagers learned more in less time than the younger children. Another report on Americans learning Russian showed a direct improvement of ability over the age range tested; that is, the ability to learn increased as the age increased, from childhood to adulthood.

There are several possible explanations for these findings. First, adults know more about the world and therefore are able to understand meanings more easily than children. Moreover, adults can use logical thinking to help themselves see patterns in the language. Finally, adults have more self-control than children.

(30)

A．Teenagers are more efficient in learning.

B．Children learn languages more easily than adults.

C．Adults are more logical than children.

D．The ability to learn languages increases with age.

听力原文：Human beings are cutting down the world's rain forests at the rate of 20 hectares

听力原文： Human beings are cutting down the world's rain forests at the rate of 20 hectares a minute (31) . Every year, 30 million hectares of rain forests are destroyed. And at this rate, most of the world's rain forests will disappear very soon.

The forests are cut down sometimes for wood, sometimes for farms so that crops and vegetables can be planted and sometimes to make way for roads. But the forests do not re-grow. The soil is very thin and it is soon washed away by the rain. The land is then too poor for the forests to begin to grow again.

There are a number of good reasons for saving the rainforests. Several important drugs in hospitals have come from the rain forests. Also they produce food. The rain forests are rich in wildlife, too. They cover less than 10% of the world's land, but they contain 40%～50%of the world's species of plants and animals (29) . The trees supply oxygen. If the rain forests are destroyed, this will change the world's weather (30) . Temperatures will go up, sea levels will rise and there will be changes in rain and snowfall.

Today, research studies in forests in Panama, New Guinea and Indonesia may help us to find solutions to save the world's rain forests.

(30)

A．15%.

B．10%.

C．About 50%.

D．Nearly 30%.
