　　　　　　　　　　　　　　 95C 　The idea of fighting a noise by making more noise sounds strange , but that's exactly what motor engineers are doing in Germany and some other countries. 　Carmakers'research and development laboratories have already proved that mixing in more noise with the help of loudspeakers can reduce the unwanted noise. 　Physicists have known about the technique for a long time. Sound is made up of pressure waves in the air. If two sound waves of the same frequency(频率)mix so that the highest point of one wave happens at the same time with the lowest point of the other wave, the result is no sound. Therefore, by producing a perfect copy of the noise and delaying it by half a wave cycle(周期), we can kill the unwanted noise. Using this technique many carmakers are racing to develop noise-killing systems both inside and outside the cars. 　Another good thing about the use of noise-killing systems is that it saves the need for a silencer, which not only reduces the weight of a car, but also makes the motor burn less oil and work better. 　Some engineers believe that the noise-killing system will be used in most cars in 1996. But the carmakers haven't decided if they will put it into production because it would add several hundred dollars to the cost of their cars. 67.Which of the following gives a general idea of how the noise-killing system works? 　 A.By producing pressure waves going in the opposite direction. 　 B.By mixing high frequency sound waves with low frequency sound waves. 　 C.By making copies of the unwanted sound waves and letting them out a little later. 　 D.By mixing new sound waves with the noise and sending them out together. 68.Besides its main function(功能)the noise-killing system can　. 　 A.make a car lighter 　 B.make a car quieter 　 C.reduce the cost of a silencer 　 D.improve the performance of a silencer 69.The noise-killing system is not yet popular mainly because　. 　 A.it increases the cost of car production 　 B.carmakers are not sure if it is necessary 　 C.it is still being tried out 　 D.people still have their doubts

When did you last see a polar bear(北极熊)?On a trip to a zoo, perhaps?If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These "Polar Bears" are people who meet frequently in the winter to swim in freezing cold water.That day, the air temperature was 3℃, and the water temperature was a bit higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group, this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.

Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so low that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.

The Polar Bears themselves are satisfied with the benefits (or advantages)of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system(循环系统)because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.

The main benefits(or advantages)of cold-water swimming are probably mental. The Polar Bears love to swim year-round;they find it fun and relaxing. As one 70-year-old woman says. "When I go into the water, I pour my troubles into the ocean and let them float away."

80.At a place where the surface temperature is 15℃, how deep do you have to dig so 　　 as to get a temperature of 75℃? 　　A.One km.　　　　　　B.Two km. 　　C.Three km.　　　　　　D.Four km.

95A 　Fat on human beings is distributed(分布)in different ways. Some fat people have a large stomach and no waistline-which makes them look round, rather like apples. Others are fatter below the waist, which makes them appear pear-shaped(梨形的). 　There are two types of fat: external fat (fat under the skin)and internal fat (fat inside the boby wall). Doctors,who have been examining the relationship between health and fatness,have found that the `pears'have less internal fat, but the `apples'have more internal fat than external fat. This seems to be what causes the health problems. 　The best treatment for fatness is to reduce the internal fat. But unfortunately it seems that dieting(节食)simply makes an apple-shaped person into a smaller apple and a pear-shaped person into a smaller pear. At the moment there is no known way of reducing the internal rather than external fat. 61.The text is mainly about　. 　 A.fatness and health　　 B.ways to lose weigh 　 C.people's figures　　 D.distribution of fat 62.Which of the following people is most likely to have health problems?

73. The word yielded in the last sentence means ___.

A. improved B. increased

C. produced D. sold

94B 　Do you always understand the directions on a bottle of medicine?Do you know what is meant by "Take only as directed"? Read the following directions and see if you understand them. 　"To reduce pain, take two tablets(药片)with water, followeed by one tablet every eight hours, as required. For night-time and early morning relief(缓解疼痛)take two tablets at bedtime. Do not take more than six tablets in twenty-four hours. For children six to twelve years old, give half the amount(量). For children under six years old ,ask for your doctor's advice. 　Reduce the amount if you suffer from restlessness or sleeplessness after taking the medicine". 　65.How many tablets at most can a person over 12 have in 24 hours? 　　A.Three　　　B.Four　　　C.Six　　　D.Eight 　66.How many tablets should a nine-year-old child normally take in 24 hours? 　　A.Half a tablet.　　　　 B.One tablet. 　　C.Two tablets.　　　　　 D.Four tablets. 　67.What is the advice for one who cannot sleep well after taking the medicine? 　　A.Stop taking the medicine at bedtime. 　　tinue to take the normal amount. 　　C.Take more than the normal amount. 　　D.Take less than the normal amount. 　68.It can be inferred from the directions that this medicine. 　　A.helps you to fall asleep quickly 　　B.may be dangerous to small children 　　ot be taken if one feels sleepy 　　D.should not be taken by children under six 　69.This text is most probably taken from a . 　　A.textbook　　　　　　 B.newsreel 　　C.doctor's notebook　　　　D.bottle of medicine

94D 　There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources(能源), such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable. 　Another way is energy conservation(节能), which means using energy more efficiently(有效地). In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of the people and the other equipment in it. 　Finally, renewable energy sources are used even though they are often expensive to develop. One form of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometre down. At six kilometres, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped(压;抽)down into the rocks and back up to the surface. Heat from the earth is already used in certain countries. 　75.How many ways of dealing with the energy problem are discussed in the text? 　　A.Two　　　　　　　B.Three 　　C.Four　　　　　　　 D.Five. 　76.From the text we learn that coal . 　　A.is quite easy to produce 　　B.is not used most efficiently 　　C.is the most common source of energy 　　D.could be renewed only by new technology 　77.The writer tells about the "special houses" because they 　　A.show the excellent skills of the builders 　　B.serve as an example of energy conservation 　　C.are heated by different sources of energy 　　D.are warmer than other types of houses 　78.The underlined words geothermal energy in the third paragraph mean . 　　A.renewable source　　　 　B.underground source 　　C.heat inside the earth　　　D.temperature of the earth 　79.Which of the following drawings shows the right way to get geothermal energy?

　　For thousands of years, man has enjoyed the taste of apples. Apples, which are about 85 percent water, grow almost everywhere in the world but the hottest and coldest areas (地区). Among the leading countries in apple production are China, France and the United States.

　　There are various kinds of apples, but a very few make up the majority of those grown for sale . The three most common kinds grown in the United States are Delicious, Golden Delicious, and Mcintosh.

　　Apples are different in colour, size, and taste . The colour of the skin may be red, green, or yellow. They have various sizes, with Delicious apples being among the largest. The taste may be sweet or tart(酸的). Generally, sweet apples are eaten fresh while tart apples are used to make applesauce(苹果酱).

　　Apple trees may grow as tall as twelve metres . They do best in areas that have very cold winters. Although no fruit is yielded during the winter, this cold period is good for the tree.

84. In what way are basenjis like cats?

　A. They make gentle sounds instead of barking

　B. They are fond of people and look like cats.

　C. They clean themselves all over.

　D. They have short, silky fur.
