听力原文： Many people catch a cold in the spring time or fall. It makes us wonder: if scientists can send a man to the moon, [33] why can't they find a cure for the common cold？ The answer is easy. There're actually hundreds of kinds of cold viruses out there. You never know which one you will get, so there isn't a cure for each one. When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and causes a blockage in it. You feel terrible because you can't breathe well, but your body is actually eating the virus. Your temperature rises and you get a fever, but the heat of your body is killing the virus. You also have a running nose to stop the virus from getting into your cells. [34] You may feel miserable, but actually y9ur wonderful body is doing everything it can to kill the cold. Different people have different remedies for colds. In the United States and some other countries, for example, people might eat chicken soup to feel better. Some people take hot bath and drink warm liquids. Other people take medicines to relieve various symptoms of colds. There is one interesting thing to note. [35] Some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer, because your body doesn't develop a way to fight it and kill it.

(30)

A．They haven't devoted as much energy to medicine as to space travel.

B．There are too many kinds of cold viruses for them to identify.

C．It is not economical to find a cure for each type of cold.

D．They believe people can recover without treatment.

听力原文：About 70 million Americans are trying to lose weight. That is almost 1 out of eve

听力原文： About 70 million Americans are trying to lose weight. That is almost 1 out of every 3 people in the United States. Some people go on diets. This means they eat less of certain foods, especially fats and sugars. Other people exercise with special equipment, take diet pills, or even have surgery. Losing weight is hard work, and it can also cost a lot of money. But why do so many people in the United States want to lose weight？

Many people in the United States worry about not looking young and attractive. For many people, looking good also means being thin. Other people worry about their health. Many doctors say being overweight is not healthy. But are Americans really fat？

Almost 30 million Americans weigh at least 20 percent more than their ideal weight. In fact, the United States is the most overweight country in the world. "The stored fat of adult Americans weighs 2.3 trillion pounds," says University of Massachusetts anthropologist George Armelages. He says burning off that stored energy would produce enough power for 900,000 cars to go 12,000 miles.

Losing weight is hard work, but most people want to find a fast and easy way to take off fat. Bookstores sell lots of diet books. These books tell readers how to lose weight. Each year, dozens of new books like these are written. Each one promises to get rid of fat.

(30)

A．To cat nothing.

B．To work hard.

C．To have surgery.

D．To cost a lot of money.

听力原文：Tea drinking was common in China for nearly one thousand years before anyone in E

听力原文： Tea drinking was common in China for nearly one thousand years before anyone in Europe had ever heard about tea. People in Britain were much slower in finding out what tea was like, mainly because tea was very expensive. It could not be bought in shops. And even those people who could afford to have it sent from Holland did so only because it was a fashionable curiosity. Some of them were not sure how to use it. They thought it was a vegetable and tried cooking the leaves. Then they served them mixed with butter and salt. Many people used to spread the used tea leaves on bread and give them to their children as sandwiches.

Tea remained scarce and very expensive in England until the ships of the East India Company began to bring it direct from China early in the seventeenth century. During the next few years so much tea came into the country that the price fell and many people could afford to buy it.

At the same time people on the Continent were becoming more and more fond of tea. Until then tea had been drunk without milk in it. But one day a famous French lady named Madame de Sevigne decided to see what tea lasted like when milk was added. She found it so pleasant that she would never again drink it without milk. Because she was such a great lady her friends thought they must copy everything she did, so they also drank their tea with milk in it. Slowly this habit spread until it reached England and today only very few Britons drink tea without milk.

(30)

A．Because they liked to cat tea leaves.

B．Because they were curious about the taste of tea leaves,

C．Because they did not know how to do with tea.

D．Because they wanted to make sandwiches with tea.

听力原文：New research from Australia shows that pets are good for your health. The finding

听力原文： New research from Australia shows that pets are good for your health. The findings of this new study suggest that people who have pets are at less risk from heart disease than those who do not.

The new research was carried out over three years and examined 3,000 people. They took tests that measured a variety of different factors known to be involved in heart disease--blood pressure and blood levels. Also, people were asked about their lifestyles. The 800 people who owned pets had low levels on each of the factors measured than those who did not own pets. The study 'also showed that it did not matter what kind of pet was owned--a cat was as good as a dog— so the benefits could not be attributed to the exercises involved in walking a dog.

The question is just how pets manage to make their owners more healthy. The obvious answer is that they make their owners feel more relaxed and happy. The Australian scientists who organized this study commented that if a new drug was available that was as effective as simply having a pet, then this drug would undoubtedly be considered a breakthrough in the control of heart disease.

(30)

A．Pets manage to make their owners more healthy.

B．Pets spread many kinds of disease to men.

C．Pet owners enjoy better health because of exercises.

D．Pets can sometimes cause high blood pressure in man.

听力原文：Of the thousands of different kinds of animals that exist in the world man has le

听力原文： Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets, and offer him companionship; some give him protection, and some do hard work which man cannot do for himself.

Trained and tamed for many generations, domestic animals are not accustomed to wandering in search of food and shelter. They look to their masters to provide for their needs, and as long as these are supplied, they are content to do what their masters require.

All domestic animals need proper food. It must be suitable for them, sufficient in quantity, fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps, and then wonder why the animal seems listless and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health.

Cats and dogs do not need a place of their own, although a very big dog is better off in a doghouse than in the house. The cat, an independent creature, is very good at finding the safest and most comfortable spot when she wants to take a nap. But cows and horses and similar animals must have proper stables, clean, dry and well ventilated.

Even well cared-for animals may sometimes fall ill. If this happens, the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals, and in some countries organizations exist to provide them free or at a cheap price. Useful, friendly, hardworking animals deserve to have some time, money and attention spent on their health.

(33)

A．Looking for food by themselves.

B．Being fed properly.

C．Overfeeding or underfeeding.

D．Living on people's odds and ends of table scraps.

听力原文： Why do so many people live to a healthy old age in certain parts of the world？ [31] What is the secret of their long lives？ Three things seem to be very important: [29] fresh air, fresh food and a simple way of life.

For years the Hunzas of the Himalayas did not need policemen, lawyers or doctors. There was no crime, no divorce and not much illness in their society. [30] They were a happy, peaceful people, famous all over India for their long, healthy lives.

(30)

B．Clean air, fresh food and less exercise.
