W: Sounds right to me.

M: So, what exercises do the experts recommend？

Section B

Directions: In this section, you will hear 3 short passages. At the end of each passage, you will hear some questions. Both the passage and the questions will be spoken only once. After you hear a question, you must choose the best answer from the four choices marked A, B, C and D.

听力原文： Many people believe they are supposed to drink eight glasses of water a day, or about two liters. Why？ Because that is what they have been told all their life. But a new report offers some different advice. Experts say people should obey their bodies; they should drink as much water as they feel like drinking.

The report says most healthy people meet their daily needs for liquid by letting thirst be their guide. The report is from the Institute of Medicine, part of the National Academies. This organization provides scientific and technical advice to the government and the public.

The report contains some general suggestions. The experts say women should get about two-point- seven liters of water daily. Men should get about three-point-seven liters. But wait--in each case, that is more than eight glasses.

There is an important difference. The report does not tell people how many glasses of water to drink. In fact, the experts say it may be impossible to know how many glasses are needed to meet these guidelines. This is because the daily water requirement can include the water content in foods. People do not get water only by forcing themselves to drink a set number of glasses per day. People also drink fruit juices and sodas and milk. They drink coffee and tea. These all contain water.

As you might expect, the Institute of Medicine says people need to drink more water when they are physically active. The same is true of those who live in hot climates. Depending on heat and activity, people could need two times as much water as others do.

26. What does the new report advise people to do？

27.What function of the Institute of Medicine is mentioned in the passage？

28.Why do experts claim it impossible to know how many glasses of water are needed per day？

(23)

A．Drink at least two liters of water a day.

B．Drink as much water as possible dally.

C．Drink as much water as their bodies need.

D．Drink no water before physical exercises.

Hypnosis(催眠)

1 Increasing numbers of American doctors are using a technique known as hypnosis. They say hypnosis often can help persons suffering pain and stress. It also can help speed the healing of bums, and treats some forms of asthma and some skin diseases. Hypnosis is not new. It has been used for many years both in scientific research and to please crowds at public gatherings,

2 Hypnosis is commonly described as a condition similar to sleep. But, experts say it is more a form. of deep thought. The thought becomes so intense that it is longer just a thought. To the per son, it becomes reality.

3 Hypnotized patients are reported to have increased self-control and a reduced sense of pain. Some doctors use hypnosis to limit pain during a medical operation. Hypnosis is used mainly when the patient may have problems with usual anesthetic or pain-killing drugs.

4 Experts say there is little chance that a patient will awaken during such an operation. But, if this happens, the operation is temporarily halted, and the patient hypnotized again. Doctors may advise hypnosis for women who are giving birth. Dentists may use it in place of traditional pain-killing drugs, such as novocaine (麻醉药).

5 Hypnosis also has been used to treat burn victims. Researchers have found that bum victims who are hypnotized improve faster that those who are not. But, they are not sure why this happens.

6 Hypnosis can reduce or end a patient's pain. But experts say this does not mean the patient is cured. The problem that caused the pain still must be treated.

7 Experts also say persons cannot be forced to do something they would normally oppose. That is why hypnosis often is not effective in treating cigarette smokers and persons who eat or drink too much. The success of the technique depends on how much someone wants it to succeed.

he substance which people cannot resist in cigarettes is nicotine. When people smoke the nicotine goes directly into the blood stream and makes people feel relaxed. A smoker's body gets accustomed to the nicotine

and if he stops smoking he feels nervous. Many smokers try to stop smoking but because of their dependence on nicotine they feel so uncomfortable that they often find it too hard to stop.

Many people also like the taste of tar in cigarettes. However, it is the tar that causes cancer. While governments and health experts have tried to make people give up smoking entirely, cigarette manufacturers have to keep selling them by producing cigarettes with less tar. Many people in western countries have welcomed these cigarettes since they find it difficult to stop smoking but want to reduce the risk to their health.

Why do so many people become dependent on cigarettes？

A．Because they like the taste of tar.
