According to the American Automobile Association , since 1964 all cars sold in the United States have been equipped with seat belts (These are also called safety belts.) . Many studies of automobile accidents have shown that safety belts can save lives. One study showed that forty percent of those killed in auto accidents could have been saved if they had been wearing seat belts.
Unfortunately, belts are worn only by a small percentage of drivers and passengers — about fifteen percent in cities, and only nine percent in small towns. And safety belts cannot protect people who do not wear them.
In order to find out what kinds of people do wear seat belts, a study was made in several cities of the United States. The following facts were about those who use their safety belts:
1. They do not smoke while driving.
2. They have had more education than non-users.
3. They know someone who was injured (but not killed) in an automobile accident.
Advertisements based on these facts have been printed in newspapers and magazines in order to teach people the importance of using seat belts. But these advertisements have not helped much. Some people believe there should be a law requiring drivers and passengers to use safety belts. In Australia, where there is such a law, deaths in auto accidents have decreased twenty-four percent.
The passage is mainly about ______.
A. automobiles in the United States B. accidents involving cars
C. safety belts for drivers and passengers D. traffic jams
The passage tells us that in Australia ______.
A. a law requires drivers and passengers to use seat belts
B. about 50% of the drivers wear seat belts
C. the importance of seat belts is advertised in newspapers and magazines
D. the auto accidents have kept the same percent as in the US
People who live in small towns _____.
A. have fewer accidents than those who live in cities
B. are less likely to use seat belts than those who live in cities
C. welcome the passing of a law to require the use of seat belts
D. are against the law that requires people to use seat belts
Many studies have shown that seat belts can save lives of those who ______.
A. never wear seat belts
B. seldom wear seat belts
C. are wearing seat belts when the accidents happen
D. sit at the back of the cars

Science can’t explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.
Any owner will tell you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people ---half of them pet owners ---while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don’t judge.
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn’t lose any more weight than those without dogs but, say researchers, got more exercise overall---mostly with their dogs --- and found it worth doing.

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
【小题1】The text mainly discusses the relationship between .
| A．heart problems and air quality |
| B．heart problems and exercising |
| C．heart problems and smoking |
| D．heart problems and fatty food |
| A．relatively high | B．extremely low |
| C．relatively low | D．extremely high |
| A．Eating fatty food has immediate effects on your heart. |
| B．The EPA conducted many studies on air quality. |
| C．Moderate air quality is more harmful than smoking, |
| D．Stricter regulations on pollutants should be made. |
| A．inform | B．persuade | C．describe | D．entertain |
