    【题目】Want to stay away from colds? Put on a happy face.

    Compared to unhappy people, those who are cheerful and relaxed are less likely to suffer from colds, according to a new study. It's possible that being happy helps the body fight illnesses, say the researchers from New York University.

    “It seems that positive(积极的) feelings may reduce (减少) the danger of illness,” said the study's chief researcher Sheldon Cohen.

    In an earlier study, Cohen found that people who were cheerful and lively caught coughs and colds less often. People who showed feelings were also less likely to tell their doctors that they felt ill.

    In this study, Cohen's interviewed 193 adults every day for two weeks. During the interviews, the people told researchers about the happy or sad feelings they had that day. After the two weeks, the people were given colds by doctors and had to stay alone in a room for six days.

    The result showed that everyone in the study was equally(相等地) likely to get ill. But for people who said they felt happy during the research period, their illness was less serious and lasted for a shorter time.

    Cohen believes that when people experience positive feelings, their body may produce a chemical that helps fight illness and disease. So if you are worried about your health, look on the bright side more often.

    A. People talked about their feelings every day.

    【题目】In the US, elementary and middle schools are advised to give students two and a half hours of physical activity a week. That is what the Centers for Disease Control and Prevention and the American Heart Association recommend. They say high schools should provide about four hours of physical activity each week.

    Yet many schools across the country have reduced their physical education programs. Criticism of the cuts has led in some places to efforts to give students more time for exercise, not less. The future health of Americans may depend on it. A study reports that life expectancy has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in obesity，smoking and high blood pressure. They also blame differences in health services around the country.

    In 2006, a study found that only 4% of elementary schools provided daily physical education all year for all grades. This was true of 8% of middle schools and 2% of high schools. The study also found that 22% of all schools did not require students to take any P. E. One problem for P. E. teachers is that schools are under pressure to put more time into academic subjects.

    Also, parents may agree that children need exercise in school. Yet many parents today still have bad memories of being chosen last for teams because teachers favored the good athlets in class.

    But experts say P. E. classes have changed. They say the goal has moved away from competition to personal performance, as a way to build a lifetime of activity. These days, teachers often lead activities like weight training and yoga.

    Some parents like the idea of avoiding competitive sports in P. E. class. Yet others surely dislike that idea. In the end，schools may find themselves in a no-win situation.
