听力原文：Researchers do not know why people think some colours are warm and other colours

听力原文： Researchers do not know why people think some colours are warm and other colours are cool. However, almost everyone agrees that red, orange, and yellow are warm and that green, blue, and violet are cool. Perhaps warm colours remind people of warm days and cool colours remind them of cool days. Because in the north the sun is low during the winter, the sunlight appears quite blue. Because the sun is higher during the summer, the hot summer sunlight appears yellow.

People associate colours with different holidays. For example, red is associated with Valentine's Day. On February 14th, Americans send red hearts to people they love. People associate orange with Halloween in October and Thanksgiving Day in November. On October 31 st, many Americans put large orange pumpkins in their windows for Halloween. Many people wear green on St. Patrick's Day, March 17th. Violet is a dignified colour which is associated with Easter. On Easter Sunday, people decorate baskets with purple ribbons.

Many expressions in English use colours. These expressions show how people feel about the colours. For example, people associate red with a strong feeling like anger. When someone is very angry, people say that he or she sees red. Red is an active colour. A red-letter day is a lucky day. When criminals are caught in the middle of a crime, people say that they are caught red-handed. Green is the colour of grass and leaves. When someone grows plants well, people say he or she has green fingers. Blue is a sad, thoughtful colour. When someone is very sad, people say he or she is feeling blue. Blues is a kind of jazz that is usually very sad and slow.

(33)

A．A warm colour is a colour that is often used in restaurants.

B．A warm colour is a colour that gives off heat.

C．A warm colour is a colour near the red end of the light spectrum.

D．A warm colour is a colour that makes people feel upset.

听力原文：Do you have a tough math test coming up？ Then listen to some classical piano musi

听力原文： Do you have a tough math test coming up？ Then listen to some classical piano music just before the test. You might end up with a higher score (30) . Researchers at a university in California conducted an experiment. They asked a group of college students to listen to some piano music by a famous 18 th century composer before taking a math test. They were surprised to find that the students' scores jumped 8 to 9 points. The music seems to excite nerve activities in the brain (31) ; similar to the activity that occurs when a person is figuring out a math problem. However, the scientists warn that before you get too excited about applying this method to your math test, you should remember that brain-exciting effects lust only 10 to 15 minutes (32) . Would rock music work as well as the piano music do？ No, the scientists say. In fact, the less complex music might even interfere with the brains' reasoning ability.

(31)

A．How to improve your reasoning ability.

B．Why classical music is popular with math students.

C．The difference between classical music and rock music.

D．The effects of music on the results of math tests.

听力原文： Have you eaten too much over the holidays？ You should try fidgeting, or moving your hands or feet for a while. Those around you might not like it, but scratching and twitching is an important way of burning up calories.

American researchers have found that some people's squirming and wiggling equals several miles of jogging each day.

The scientists, based at the National Institute of Health's laboratory in Phoenix, Arizona, are studying why some people get fat and others stay slim.

In one study, 177 people each spent 24 hours in the institute's respiratory chamber—a room where the amount of energy people expend is measured by their oxygen and carbon dioxide levels. By the end of the day, some people had burned up 800 calories in toe-tapping, finger-drumming and other nervous habits. However, others had expended only 100 calories.

The researchers found that slim women fidget more than fat women, but there was net significant difference in men. Heavy people expend more energy when they fidget than do thin people.

(23)

A．Keeping moving hands and feet.

B．Jogging several miles.

C．Walking a long distance.

D．Taking deep breathes.

听力原文：M: Did you watch" Undersea Discovery" last night？

W: No, I missed it. Did you？

M: Yeah. It was pretty good--it was about barnacles.

W: Hmm.

M: You know how they stick themselves to stuff in the ocean－like rocks or boats？

W: Uh-huh.

M: Well, they do that when they're young, and then they stay in the same place forever.

W: It figures. Have you ever tried removing one of those things？ Last summer I tried to scrape some off a pier—I had to give up after a while. You'd think they wouldn't be able to stick like that underwater.

M: Yeah. These biomedical researchers were talking about its possible uses. Orthopedists could use it for mending broken bones; or it could be used in dentistry.

W: I wish I'd seen that.

(20)

A．The reproductive cycle of barnacles.

B．A new source of protein.

C．Types of sea animals.

D．The adhesive quality of barnacles.

听力原文： If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise, and as a result, we are growing old unnecessarily soon. Professor Taiju Matsuzawa wanted to find out why quite healthy farmers in northern Japan appeared to be losing their ability to think and reason at a rather early age, and bow the speed of getting old could be slowed down.

With a team of researchers at Tokyo National University, he set about measuring brain volumes of a thousand people of different jobs.

Computer technology helped the researchers to get most measurements of the volume of the front and side parts of the brains, which have something to do with intellect and feelings, and decide the human character. As we all know, the back part of the brain, which controls tasks like eating and breathing, does not contract with age.

Contraction of the front and side parts—as cells die off—was seen in some people in their thirties, but it was still not found in some sixty and seventy-year olds.

Matsuzawa concluded from his tests that there is a simple way to prevent the contraction—using the head.

The findings show that contraction of the brain begins sooner in people in the country than in the towns. Those with least possibility, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm worker, bus drivers and shop assistant.

(30)

A．An examination of farmers in northern Japan.

B．Tests given on a thousand old people.

C．Examining the brain volumes of different people.

D．Using computer technology.

听力原文：As researchers learn more about how children's intelligence develops, they are in

听力原文： As researchers learn more about how children's intelligence develops, they are increasingly surprised by the power of parents. The power of the school has been replaced by the home. Studies have shown that factors like child's understanding of language, his learning patterns, and his curiosity are well established before the child enters school at the age of six. Studies have also shown that even after school begins, children's achievements have been far more influenced by parents than by teachers. This is particularly true about language learning.

However, it's sad to see that so many parents are not making the most of their child's intelligence. Until recently parents had been intimidated by educators who asked them not to educate their children. But many teachers now realize that children cannot be educated only at school and parents are being asked to contribute both before and after the child enters school.

Parents have been particularly afraid to teach reading at home. Of course, children shouldn't be pushed to read by their parents, but educators have discovered that reading is best taught individually and the easiest place to do this is at home. Many four-or five-year-old children, who have been shown a few letters and taught their sounds, will spontaneously make up single words of their own with these letters even before they have been taught to read.

(34)

A．It depends on inheritance.

B．School education plays a major role.

C．It's influenced more by environment than by genes.

D．The power of parents proves to be a greater contribution.

听力原文： During the past decade, there has been a rapid increase in violent crimes throughout the work. Not only has there been a frightening increase of murders, but also chances of being attacked and robbed have grown. Many old people avoid leaving their apartments.

The exact cause of this horrifying development has not been found. Some researchers think that the growth of crime on TV is related to the growth of violence on streets. Others blame the constant threat of complete destruction from nuclear explosions. If the world is going to be blown up, why not enjoy yourself fully!

Regardless of the cause or causes, a fundamental change in attitude among people is easy to see. Years back, the old saying "Practice what you preach" was a popular one. People had moral standards they could follow: concern about their fellow human beings.

Today people have become "l-centered". They are more interested in pursuing immediate and selfish pleasures. The best advice they can give is "Do what I say, not what I do." They are saying, "There are moral principles to follow if you want to, but don't use me as a guide since I no longer follow them."

(30)

A．Population.

B．Wars.

C．Nuclear explosions.

D．Violence in crime.

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：When people care for an elderly relative, they often do not use available communi

听力原文： When people care for an elderly relative, they often do not use available community services such as adult daycare centers. If the caregivers are adult children, they are more likely to use such services, especially because they often have jobs and other responsibilities. In contrast, a spouse usually the wife, is much less likely to use support services or to put the dependent person in a nursing home. Social workers discover that the wife normally tries to take care of her husband herself for as long as she can in order not to use up their life savings. Researchers have found that caring for the elderly can be a very positive experience. The elderly appreciated the care and attention they received. They were affectionate and cooperative. However, even when care-giving is satisfying, it is hard work. Social workers and experts on aging offer caregivers and potential caregivers help when arranging for the care of an elderly relative. One consideration is to ask parents what they want before they become sick or dependent. Perhaps they prefer going into a nursing home and can select one in advance. On the other hand, they may want to live with their adult children. Caregivers must also learn to state their needs and opinions clearly and ask for help from others especially brothers and sisters. Brothers and sisters are often willing to help, but they may not know what to do.

Questions:

29. Why are adult children more likely to use community services to help care for elderly parents？

30. Why are most wives unwilling to put their dependent husbands into nursing homes？

31. According to the passage，what must caregivers learn to do？

(30)

A．They think they should follow the current trend.

B．Nursing homes are well-equipped and convenient.

C．Adult day-care centers are easily accessible.

D．They have jobs and other commitments.

听力原文： Anyone who's been married has the experience of arguing with your spouse. Those romantic days of courtship have given way to arguing about doing the dishes and taking out the garbage. But, as any marriage advisor will tell you, (32) at least some fighting is a healthy part of a relationship.

According to a study done by researchers at Ohio State University, though, marital stress has its downside as well. According to the study, the stress that a married couple experiences during a typical argument can slow the body's power to heal wounds by up to two days.

(33) The study involved forty two married couples who'd been together for an average of twelve years. First, each spouse was given small wounds on their arms and took tests to determine their stress levels. Then they were videotaped while having a supportive discussion about their relationship.

Two months later the couples were again given small wounds and this time videotaped while discussing something more emotionally tensional. (34) The researchers found that the wounds took one day longer to heal after the stressful discussion than they did after the supportive discussion. (35) Couples that had really hostile arguments took as long as two extra days to heal their wounds.

The researchers are still trying to determine why higher levels of stress slow the wound healing process. But the findings could be important in many ways. Hospitals, for example, might take more care to make hospital stays less stressful, so patients will heal faster.

32. What is the advisor's view about the arguments？

33.What kinds of persons are involved in the study？

34.In healing the wound，how many days longer does the stressful discussion take than the supportive one？

35.What can we learn from the study done by researchers at Ohio State University？

(33)

A．Arguments do not always occur between couples.

B．Arguments or fights may lead to the end of the marriage.

C．Couples should argue with each other properly.

D．Arguments can be avoided after the romantic days of courtship.
