Physical fitness refers to good health, and is the result of regular exercise, proper diet and nutrition, and proper rest for physical recovery. A person who is physically fit will be able to walk or run without getting breathless and he or she will be able to carry out the activities of everyday living and will not need help. How much each person can do will depend on their age and whether they are a man or woman. A physically fit person usually has a normal weight for height. The relation between height and weight is called the Body Mass Index. A taller person can be heavier and still be fit. If a person is too heavy or too thin for the height it may affect the health.  Mental health refers to a person's emotional and psychological well-being. "A state of emotional and psychological well-being in which an individual is able to use his or her thinking and emotional(feeling) abilities, function in society, and meet the ordinary demands of everyday life." One way to think about mental health is by looking at how well a person functions. Feeling capable and efficient, being able to handle normal levels of stress, having good friends and family, and leading an independent life, and being able to "bounce back" or recovering from hardships, are all signs of mental health. Public Health refers to trying to stop a disease that is unhealthy to the community, and does not help in long life or promote your health. This is fixed by organized efforts and choices of society, public and private clubs, communities and individuals. It is about the health of many people, or everybody, rather than one person. Public health stops instead of encouraging a disease through surveillance  of cases. To prevent being sick, it is good to do healthy behaviors, such as hand washing, vaccination programs and so on. When infectious diseases break out, washing hands may be especially important. Once Bird Flu takes place, that refers to   _  . A) the problem of public health B) the problem of mental health C) the problem of physical health D) the importance of washing hands.

Meals at the family dinner table could be the key to preventing a generation of  teenage girls from developing eating disorders . New research shows girls who regularly have family meals are much less likely to adopt extreme weight-control behaviors such as vomiting, and using diet pills. The research, published in the international journal Archives of Pediatrics and Adolescent Medicine, surveyed students aged 13 to 17 in 2003 and followed them up five years later. Regular family meals were found to have a protective effect regardless of the age, weight, socioeconomic status, dieting habit or relationship with the family. Belinda Dalton, director of the eating disorder clinic The Oak House, said eating with family helped "normalize" young people's relationship with food. "When teens are feeling that they are not managing, they turn to something that they can control and food is something available and accessible for them to control. Clearly, if they are sitting with their family on a regular basis, then their family can be more in control of their eating," Ms Dalton said. "It's about young people feeling connected within their family, and  _ builds self-esteem and a sense of worth and works very actively against someone developing an eating disorder. An eating disorder expert, Kirsty Greenwood, said meal times were often difficult for sufferers. "It's typical that they feel very ashamed of their eating habits and often won't eat with other people. Perhaps it's because they haven't experienced the important of the family meal while growing up," she said. The study found eating regular family meals made no difference to the future eating habits of boys. We can infer from the text that   _  . A) Ms Dalton advises parents to get children under full control B) Kirsty Greenwood suggests that the time for meals be fixed C) the effect of regular family meals on boys differs from that on girls D) experience is more important than indirect knowledge

The old saying that practice makes perfect seems to make no sense when it comes to schoolwork. Many educators today are looking for evidence to support the case for homework, but are coming up empty-handed. Mary Jane Cera is the academic administrator for the Kino School, and she maintains a no-homework policy across all grades. The purpose of the policy is to make sure learning remains a joy, not a thing that discourages social time and creative activity. At the Kino school, Cera says children often choose to take their favorite parts of school home. "A lot of what we see kids doing is practicing music with their friends, and taking experiments home to show their parents," she says. Surveys of Kino graduates suggest that the early control they are given over their education continues to serve them well into college. "One of the reasons that we continue to assign much homework is our obsession   with tests, although we can agree on the importance of kids doing better on tests through proper homework to some degree,"says author Alfie Kohn. In his book The Homework Myth, Kohn points out that no study has ever found a relation between homework and academic achievement and that if kids have no choice in the matter of homework, they're not really exercising judgment, and are instead losing their sense of self-control. However, many supporters of homework argue that life is filled with things we don't like to do, and that homework teaches self-discipline, time management and other non-academic life skills. Wherever the homework debate goes next, it's worth taking a moment to examine if we're doing the right thing about our children's education. The good news is -- it's never too late to start. According to the surveys, what influences students further study most? A) Professors' instructions. B) Time management skills. C) Early education at home. D) Freedom in choosing homework.
