As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease — especially in terms of changing our many unhealthy behaviors, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight, but does not eat very nutritious (有影响的) 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 merely "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 striving 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 strive 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 impact on the ways in which people face the challenges of daily life. Traditionally, a person is considered "well" if he________.
A. does not have any unhealthy living habits
B. does not have any physical handicaps
C. is able to handle his daily routines
D. is free from any kind of disease
Ideas about education are changing in the United States. Education today is not just a high school diploma(文凭) or a college degree. Many adults are not interested in going to college. They are interested in other kinds of learning. For them, learning does not end with a diploma. Continuing education gives these adults the opportunity to increase their knowledge about their own field or to learn about a new field. It also gives them a chance to improve their old skills or to learn new ones. Scientists, mechanics (技师) and barbers (理发师) can take classes to improve their work skills. If they know more or learn more, they can get a better job or earn more money. Continuing education classes give more adults the chance to learn new skills. There is usually a large variety of classes m choose from; typing, foreign cooking, photography, auto repair, furniture repair, or swimming. There are only some of the classes available. Some adults take classes for fun or because the class will be useful for them. Other adults take continuing education classes to improve their own lives because they want to feel better about themselves. Almost any community college or public school system has a continuing education program. There are classes in schools, community buildings or churches. Most classes are in the evenings, so working people can attend. The classes are usually small, and they are inexpensive. The new idea about education in the U.S. is that ______.
A. everyone should get a college degree
B. it’s no use for adults to go to college
C. a high school diploma is the end of education
D. adults should go on learning ’after graduating from school
