听力原文： The first step in exercising for most people is determining whether or not they should. This is particularly true with anyone over thirty-five, especially if they have been heavy smokers. (33) Likewise, young adults who have been very inactive should process slowly and with caution. A physical evaluation from a physician is recommended, preferably one that includes an exercise-stress test. While a person is exercising, a stress test detects cardiovascular (心血管的) problems that might not show up when the body is at rest. This is done by monitoring blood pressure, pulse rate, oxygen consumption, and the hearts electrical activity while exercising.

Whatever exercise program is selected, (34) it is important to start with warm-up periods. These should include stretching exercises, jumping jacks, or active walking. The idea is to increase heart rate and circulation slowly without placing a sudden strain on the heart or the muscles that are starting to work. The next phase in developing an exercise program is to determine the amount of exercise that is enough to condition the muscles and cardiovascular system without overly straining the body. This involves taking one's pulse and finding one's target zone.

(35) This target zone, or safe-training pulse rate, is established by subtracting one's age from 220 and then taking 60 percent to 80 percent of that total. If you are just starting to exercise, 60 percent is recommended; 80 percent is recommended if you are already in good condition.

Questions:33. What should the inactive young adults do when they decide to do exercise？

34.What does warm-up exercise exclude？

35.What would be the suggested the safe-training pulse rate if you are a beginner and at the age of 45？

(30)

A．To determine whether-or-not they should.

B．To process slowly and with caution.

C．To have a muscle check.

D．To increase heart rate.

听力原文：While radio broadcasting was still in its early stage the wonder of television wa

听力原文： While radio broadcasting was still in its early stage the wonder of television was already being developed. The person responsible for developing it was John Baird. In 1926 he gave the first demonstration of a television picture.

As a home entertainment, television rapidly became more popular than any other form. A news broadcast became more immediate when people could actually see the scene in question and the movements of the figures. Films could also be available. One of the advantages of travel programs was the glimpse of far-away places which many viewers would not otherwise have seen. Though much of the entertainment was of a popular kind like quiz competitions, some remarkable cultural programs were also broadcast. Just as with radio in earlier days, a group of actors and actresses became familiar in every household. One of the most popular programs on television was sport and an interesting result of the television broadcast was the increased attendance at the actual events. How far this was due to a growth in interest in the-game and how far out of the peoples desire to appeal on the screen is not clear.

(33)

A．He was the first person to appear on television.

B．It was he who discovered the wonder of television.

C．He made the very first step towards the invention of television.

D．He developed the television and was the first person to demonstrate it.

听力原文：The first significant step in the fight against infectious disease Was made in 17

听力原文： The first significant step in the fight against infectious disease Was made in 1796 with discovery of a vaccine to prevent smallpox by Edward Jenner. Jenner had become aware of the fact that milkmaids who had suffered from a mild illness, cowpox, were unlikely to catch the much more serious smallpox disease. Jenner experimented on a child, introducing cowpox into the bloodstream. Later, the child was inoculated with smallpox, but did not catch the disease. Jenner's method had, proved much safer than the fashionable technique of inoculation, which had been brought to Britain from Turkey by Lady Montague. Despite opposition from the medical establishment, many of whom made a good income from inoculation, the government backed Jenner's claims; by 1853, vaccination had become compulsory for infants.

Louis Pasteur was a French chemist who in 1867 was able to demonstrate for the first time that germs caused disease. Pasteur went on to develop vaccines for chicken cholera, anthrax and rabies. The new science of bacteriology was advanced further by a German scientist, Robert Koch. Using microscopes and innovative methods of staining germs, Koch was able to identify specific germs as being responsible for the cause of disease. In 1882-3, he identified the microbes responsible for tuberculosis (TB) and cholera.

A rivalry developed between Pasteur and Koch, based in part on the tension which existed following France's defeat in the Franco-Prussian war of 1870-1. Both scientists were recognized in their own countries for their work, and set up with research centers. In 1881, Pasteur, successfully tried vaccine which protected against anthrax in animals. Koch, who quickly heard of the breakthrough by telegram, attempted unsuccessfully to discredit Pasteur. When, in the following year, he had the opportunity to treat a boy with rabies called Joseph Meister, Pasteur succeeded in developing a rabies vaccine.

What was the first step in fighting against infectious disease？

A．The discovery of a vaccine.

B．A powerful injection.

C．The help of a milkmaid.

D．The help from government.

听力原文：The first step to stop drug abuse is knowing why people start to use drugs. The r

听力原文： The first step to stop drug abuse is knowing why people start to use drugs. The reasons people abuse drugs are as different as people are from one to another. But there seems to be one common thread: people seem to take drugs to change the way they feel. They want to feel better or to feel happy or to feel nothing. Sometimes, they want to forget or to remember. People often feel better about the roseleaf when they are under the influence of drugs. But the effects don't last long. Drugs don't solve problems. They just postpone them. No matter how far drugs may take you, it's always around trip. After a while, people who miss drugs may feel worse about themselves, and then they may use more drugs. If someone you know is using or abusing drugs, you can help. The most important part you can play is to be there. You can let your friends know that you care. You can listen and try to solve the problem behind your friend's need to use drugs. Two people together can often solve a problem that seems too big for one person alone. Studies of heavy abusers in the United States show that they felt unloved and unwanted. They didn't have close friends to talk to. When you or your friends take the time to care for each other, you're all helping to stop drugs abuse. After all, what is a friend for？

(23)

A．To show off their wealth.

B．To feel good.

C．To regain their memory.

D．To be different from others.
