Excerpt 1 Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn’t know for sure. That the evidence was inconclusive, the science uncertain That the antismoking lobby was out to destroy our way of life and the government should stay out of the way Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves.Excerpt 2 If you smoke and you still don’t believe that there’s a definite between smoking and bronchial troubles, heart disease and lung cancer, then you are certainly deceiving yourself. No one will accuse you of hypocrisy. Let us just say that you are suffering from a bad case of wishful thinking. This needn’t make you too uncomfortable because you are in good company. Whenever the subject of smoking and health is raised, the governments of most countries hear no evil, see no evil and smell no evil. Admittedly, a few governments have taken timid measures. In Britain, for example, cigarette advertising has been banned on television. The conscience of the nation is appeased, while the population continues to puff its way to smoky, cancerous death. You don’t have to look very far to find out why the official reactions to medical findings have been so lukewarm. The answer is simply money. Tobacco is a wonderful commodity to tax. It’s almost like a tax on our daily bread. In tax revenue alone, the government of Britain collects enough from smokers to pay for its entire educational facilities. So while the authorities point out ever so discreetly that smoking may, conceivably, be harmful, it doesn’t do to shout too loudly about it.Excerpt 3 The 74-page study says that pop music, as a global industry, is by far the most influential trend-setter for young people of most cultures. "Some lyrics advocate the smoking of marijuana (大麻) or taking other drugs, and certain pop stars make statements and set examples as if the use of drugs for non-medicinal purposes were a normal and acceptable part of a person’s lifestyle," the study says.Excerpt 4 I recall how annoying it was years ago when smoking everywhere was legal in California. Many complained about the restrictions when they arrived, but I didn’t, because I seriously hated watching shoppers smoking through the tomatoes and lettuce in the vegetable section of the store.People forget how sickening that used to be, especially with the butts all over the grocery store floor. Tossing a burning smoke on the ground, stomping it with your foot, and leaving it to be swept up by somebody else later was somehow OK.Excerpt 5 Mark Twain once observed that giving up smoking is easy. He knew, because he’d done it hundreds of times himself. Giving up for ever is a trifle more difficult, apparently, and it is well known that it is much more difficult for some people than for others. Why is this so Few doctors believe any longer that it is simply a question of will power. And for those people that continue to view addicts as merely "weak", recent genetic research may force a rethink.Why do a few governments take timid measures toward smoking

A.Because they are afraid of people.
B.Because diseases cost a lot.
C.Because they are afraid of reducing their revenue.
D.Because they are afraid of manufacturers.

In the 1960’s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Negative events like "serious illness of a family member" were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not reflect how you deal with stress—it only shows how much you have to deal with. And we now know that the way you handle these events dramatically affects your chances of staying healthy. By the early 1970’s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Women’s magazines ran headlines like "Stress causes illness." If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many—like the death of a loved one—are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription (处方) for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The notion that all stress makes you sick also ignores a lot of what we know about people. It assumes we’re all vulnerable (脆弱的) and passive in the face of adversity (逆境 ). But what about human initiative and creativity Many come through periods of stress with more physical and mental vigor than they had before. We also know that a long time without change or challenge can lead to boredom, and physical and mental strain.The result of Holmes-Rahe’s medical research tells us________.

A.the way you handle major events may cause stress
B.what should be done to avoid stress
C.what kind of event would cause stress
D.how to cope with sudden changes in life

Some of the most popular attractions across America are the many free concerts offered to the public throughout the year. These involve not only amateur performers, but professional artists as well. The public parks of many cities across the country usually have bandstands and large lawns. As a service to citizens, they rent out space to performers free of charge. Amateur groups, with nothing more than a desire to perform, offer their talents freely to the public. Semi-professional artists are pleased to get the chance to perform before the public to perfect their craft and nurture the hope of being discovered before beginning a professional career. Famous professionals also give free concerts to make contact with their admiring fans. Often such concerts are sponsored by a large corporate organization and offered to the public free of charge as a cultural service and support for the arts. The free concerts feature all kinds of music from rock and roll, jazz, country-western to the classics. In addition, free performances may include the plays of Shakespeare or experimental theater of modern dramatists. In New York’s Central Park there has long been a summer Shakespeare festival which draws huge crowds to the free performances. Of these concerts the ones held on a summer evening in the park are the most popular. They take on a festive air. Friends and groups gather together after work and spread out a blanket on the lawn facing the performers’ stage. The early comers get the best locations and enjoy a picnic supper while it is still daylight. The free seating is on a first come basis. Therefore, by the time the concert begins, as many as five thousand or more people may be in attendance. The concerts usually begin at 8 p. m. and are performed under the stars. The sound is made sufficiently loud so that no matter where one chooses to sit, he can hear very well. The only disturbance may be the sound of an overhead airplane on its final approach to an airport or the far-off siren (警笛声) of all ambulance on its way to the hospital. This matters little! What counts is to soak up the atmosphere created by the music and to be with friends in the flesh open air. The best part of it all is that it’s free!Many American parks give free concerts on their lawns because they________.

A.have the necessary facilities
B.can attract more visitors
C.want to serve the public
D.are in a position to invite musicians

It is hard to track the blue whale, the ocean’s largest creature, which has almost been killed off by commercial whaling and is now listed as an endangered species. Attaching radio devices to it is difficult, and visual sightings are too unreliable to give real insight into its behavior. So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 33 days monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption (爆发) for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second—slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.The passage is chiefly about________.

A.an effort to protect an endangered marine species
B.the civilian use of a military detection system
C.the exposure of a U. S. Navy top-secret weapon
D.a new way to look into the behavior of blue whales

The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise (有氧操). Millions of individuals became engaged in a variety of aerobic activities, and literally thousands of health spas developed around the country to capitalize (获利) on this emerging interest in fitness, particularly aerobic dancing for females. A number of fitness spas existed prior to this aerobic fitness movement, even a national chain with spas in most major cities. However, their focus was not on aerobics, but rather on weight-training programs designed to develop muscular mass, strength, and endurance in their primarily male enthusiasts. These fitness spas did not seem to benefit financially from the aerobic fitness movement to better health, since medical opinion suggested that weight-training programs offered few, if any, health benefits. In recent years, however, weight training has again become increasingly popular for males and for females. Many current programs focus not only on developing muscular strength and endurance but on aerobic fitness as well. Historically, most physical-fitness tests have usually included measures of muscular strength and endurance, not for health-related reasons, but primarily because such fitness components have been related to performance in athletics. However, in recent years, evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health benefits as well. The American College of Sports Medicine now recommends that weight training be part of a total fitness program for healthy Americans. Increased participation in such training is one of the specific physical activity and fitness objectives of Healthy People 2000, National Health Promotion and Disease Prevention Objectives.The word "spas" (Line 3, Para. 1) most probably refers to________.

A.sports activities
B.places for physical exercise
C.recreation centers

Tracking whales is but one example of an exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies. Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption (爆发) for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second—slower than through land but faster than through air. What is most important, different layers of ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low-frequency ones, can often travel thousands of miles.In the last sentence of fourth paragraph, the word "proposed" can be replaced by________.

A.supposed
B.suggested
C.imagined
D.planned

The fitness movement that began in the late 1960s and early 1970s centered around aerobic exercise (有氧操). Millions of individuals became engaged in a variety of aerobic activities, and literally thousands of health spas developed around the country to capitalize (获利) on this emerging interest in fitness, particularly aerobic dancing for females. A number of fitness spas existed prior to this aerobic fitness movement, even a national chain with spas in most major cities. However, their focus was not on aerobics, but rather on weight-training programs designed to develop muscular mass, strength, and endurance in their primarily male enthusiasts. These fitness spas did not seem to benefit financially from the aerobic fitness movement to better health, since medical opinion suggested that weight-training programs offered few, if any, health benefits. In recent years, however, weight training has again become increasingly popular for males and for females. Many current programs focus not only on developing muscular strength and endurance but on aerobic fitness as well. Historically, most physical-fitness tests have usually included measures of muscular strength and endurance, not for health-related reasons, but primarily because such fitness components have been related to performance in athletics. However, in recent years, evidence has shown that training programs designed primarily to improve muscular strength and endurance might also offer some health benefits as well. The American College of Sports Medicine now recommends that weight training be part of a total fitness program for healthy Americans. Increased participation in such training is one of the specific physical activity and fitness objectives of Healthy People 2000, National Health Promotion and Disease Prevention Objectives.People were given physical fitness tests in order to find out________.

A.how well they could do in athletics
B.what their health condition was like
C.what kind of fitness center was suitable for them
D.whether they were fit for aerobic exercise

Excerpt 1 Do you remember all those years when scientists argued that smoking would kill us but the doubters insisted that we didn’t know for sure. That the evidence was inconclusive, the science uncertain That the antismoking lobby was out to destroy our way of life and the government should stay out of the way Lots of Americans bought that nonsense, and over three decades, some 10 million smokers went to early graves.Excerpt 2 If you smoke and you still don’t believe that there’s a definite between smoking and bronchial troubles, heart disease and lung cancer, then you are certainly deceiving yourself. No one will accuse you of hypocrisy. Let us just say that you are suffering from a bad case of wishful thinking. This needn’t make you too uncomfortable because you are in good company. Whenever the subject of smoking and health is raised, the governments of most countries hear no evil, see no evil and smell no evil. Admittedly, a few governments have taken timid measures. In Britain, for example, cigarette advertising has been banned on television. The conscience of the nation is appeased, while the population continues to puff its way to smoky, cancerous death. You don’t have to look very far to find out why the official reactions to medical findings have been so lukewarm. The answer is simply money. Tobacco is a wonderful commodity to tax. It’s almost like a tax on our daily bread. In tax revenue alone, the government of Britain collects enough from smokers to pay for its entire educational facilities. So while the authorities point out ever so discreetly that smoking may, conceivably, be harmful, it doesn’t do to shout too loudly about it.Excerpt 3 The 74-page study says that pop music, as a global industry, is by far the most influential trend-setter for young people of most cultures. "Some lyrics advocate the smoking of marijuana (大麻) or taking other drugs, and certain pop stars make statements and set examples as if the use of drugs for non-medicinal purposes were a normal and acceptable part of a person’s lifestyle," the study says.Excerpt 4 I recall how annoying it was years ago when smoking everywhere was legal in California. Many complained about the restrictions when they arrived, but I didn’t, because I seriously hated watching shoppers smoking through the tomatoes and lettuce in the vegetable section of the store.People forget how sickening that used to be, especially with the butts all over the grocery store floor.

He knew, because he’d done it hundreds of times himself. Giving up for ever is a trifle more difficult, apparently, and it is well known that it is much more difficult for some people than for others. Why is this so Few doctors believe any longer that it is simply a question of will power.

A.there was no scientific evidence of the correlation between smoking and death
B.the number of early deaths of smokers in the past decades was insignificant
C.people had the freedom to choose their own way of life
