It doesn't take a rocket scientist long time to figure out that there are better things you could do for your health than take deep breaths on a smoggy（烟雾的）day. A growing pile of research suggests that even relatively low levels of air pollution may be more harmful than previously realized, to both heart and lungs(肺). The latest articles from researchers, published this week in the New England Journal of Medicine, focuses on how particulate (微粒) matter from air pollution affects lung function.
“The effect of low levels of particulate pollution found in many urban areas is not unlike secondhand smoke,” experts say. Studies show that short-term effects from particulates include diminished（减少） lung function, coughing, wheezing, and heart attacks. Long-term exposure can also slow normal lung growth, damage lung airways, and increase the risk of dying from lung cancer.
Certain populations, such as the very old and the very young, are the most vulnerable to air pollution. However, even the most alarming studies conducted in the most polluted areas suggest that the average person's individual risk from exposure (暴露) is very slight. Relative risk numbers often seem more frightening than they actually are. For example, an earlier study published in the New England Journal of Medicine found that short-term exposure to traffic fumes tripled ( 成为3倍) the risk of heart attacks in heart-attack survivors.
Short of moving to the countryside or at least away from busy roads, shielding yourself from the effects of air pollution is not easy. Masks won't work. “At the very least,” suggests Murray Mittleman, a cardiologist at Harvard University, “people who regularly exercise outdoors near highways may want to consider remapping their route.”

As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease－especially in changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought about this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.

The field of medicine has not traditionally distinguished between someone who is just “not ill” and someone who is in excellent health and pays attention to the body’s special needs. Both types have simply been called “well”. In recent years, however, some health specialists have begun to apply the terms “well” and “wellness” only to those who are actively attempting to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body’s condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap (缺陷) may be “well”, in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. “Wellness” may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can struggle for. People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial influence on the ways in which people face the challenges of daily life.

No one can avoid being influenced by advertisements. Much as we may pride ourselves on our good taste, we are no longer free to choose the things we want, for advertising exerts a subtle influence on us. In their efforts to persuade us to buy this or that product, advertisers have made a close study of human nature and have classified all our little weaknesses.

Advertisers discovered years ago that all of us love to get something for nothing. An advertisement which begins with the magic word FREE can rarely go wrong. These days, advertisers not only offer free samples, but free cars, free houses, and free trips round the world as well. They devise hundreds of competitions which will enable us to win huge sums of money. Radio and television have made it possible for advertisers to capture the attention of millions of people in this way.

During a radio programme, a company of biscuit manufacturers once asked listeners to bake biscuits and send them to their factory. They offered to pay $10 a pound for the biggest biscuit baked by a listener. The response to this competition was tremendous. Before long, biscuits of all shapes and sizes began arriving at the factory. One lady brought in a biscuit on a wheelbarrow. It weighed nearly 500 pounds. A little later, a man came along with a biscuit which occupied the whole of his car. All the biscuits that were sent were carefully weighed. The largest was 713 pounds. It seemed certain that this would win the prize. But just before the competition closed, a lorry arrived at the factory with a truly colossal biscuit which weighed 2,400 pounds. It had been baked by a college student who had used over 1,000 pounds of flour, 800 pounds of sugar, 200 pounds of fat, and 400 pounds of various other ingredients. It was so heavy that a crane had to be used to remove it from the lorry. The manufacturers had to pay more money than they had anticipated, for they bought the biscuit from the student for $24,000.

C. Different means are being used to cheat people.

D. They produce too many products that can’t be sold out.

3..
