Playing tennis regularly could help keep people off death, but football, rugby and running may not help people to live longer, a study suggests.

A study followed more than 80,000 people for an average of nine years to find out if certain sports protected them against early death. It found that people who played racket sports regularly were the least likely to die over the study period, reducing their individual risk by 47 percent compared with people who did no exercise. Swimmers also reduced their chance of death by 28 percent, aerobics (有氧运动) fans by 27 percent and cyclists by 15 percent. Yet running appeared to have no impact at all on dying early, and neither did playing football or rugby.

Scientists say the difference may lie in the social aspect which goes alongside sports like tennis and squash (壁球), which often involve clubs and organized activities outside of the game. It means that people often have larger social net-works and tend to keep up activities into later life, both of which are proven to be good for health.

In contrast, people who play team sports often do not move onto a new sport once their teams break up for family, or injury reasons. They become watchers rather than participants in their chosen activity.

The researchers found that playing racket sports was associated with a 56 percent lower risk from heart death. Similarly, swimmers lowered their heart disease or stroke risk by 41 percent, and people who took part in activities like aerobics, dance or gymnastics lowered their risk by 36 percent. But again running, football and rugby had no significant impact on heart deaths.

However, other experts argue that this study must not be misinterpreted as showing that running and football do not protect against heart disease. In this study both runners and footballers had a lower rate of death from heart disease.

C.Rugby. D.Tennis.

A new Japanese research has suggested that regularly eating mushrooms could help lower the risk of cancer. The researchers found that the men who consumed mushrooms once or twice a week had an 8 percent lower risk of developing cancer, regardless of how much fruit and vegetables, or meat and dairy products they ate—compared to those who ate mushrooms less than once per week. Eating mushrooms more often appeared to bring even bigger benefits, with those who consumed mushrooms three or more times per week showing a 17 percent lower risk than those who ate mushrooms less than once a week.

Eating mushrooms also appeared to be particularly beneficial among those who ate a large amount of meat and dairy products, little fruit and few vegetables. The findings, published in the International Journal of Cancer, are the first to suggest that there may be an association between eating mushrooms and a lower risk of cancer.

“Test-tube studies and studies conducted on living organisms have shown that mushrooms have the potential to prevent cancer” said lead researcher Shu Zhang. “To the best of our knowledge, this is the first study indicating the cancer-preventive potential of mushrooms at a population level.” Zhang added that, “mushrooms are a good source of vitamins, minerals and antioxidants, especially L-ergothioneine,” which is believed to help fight against stress, and that is cell imbalance caused by lifestyle choices such as poor diets and exposure to environmental poisons. This imbalance can lead to chronic inflammation, resulting in chronic diseases such as cancer.

“Considering the average American consumes less than 5 grams of mushrooms per day, which is lower than that consumed by the participants in this study (7.6 g/day), one would expect that even a small increase in mushroom consumption can offer potential health benefits,” said Zhang. However, Zhang added that, “Although our study suggests regular consumption of mushrooms may reduce the risk of cancer, we also want to emphasize that eating a healthy and balanced diet is much more important than filling your shopping basket with mushrooms.”

1.What is the new Japanese research about?

A.Healthy lifestyle reduces the risk of cancer.

B.Often eating mushrooms reduces the risk of cancer.

C.Drinking dairy products is good for our health.

D.Eating fruit and vegetables makes us healthier.

2.Who seem to especially benefit from eating mushrooms?

A.People who are over fat and having a poor diet.

B.People who are feeling over stressed.

C.People who consume much meat but few vegetables and little fruit.

D.People who consume many dairy products and suffer cancer.

3.Why can the mushroom help reduce the risk of cancer?

A.It avoids the stress from a disease.

B.It reduces environmental poisons.

C.It hell helps reduce weight.

D.It has a source of cancer-preventive.

4.What does the underlined word “inflammation” probably means?

A.A state of being physically healthy.

B.A state of keeping body balance.

C.A physical condition that someone needs to be on a diet.

D.A condition that a part of the body becomes red, sore and swollen.

Adults think playing sports is good for children because it is fun and helps children keep in shape and even develop their social skills when they play with others. However, playing sports can have bad effects on children. It may produce feelings of poor self-esteem(自负) or aggressive（好斗的） behavior in some children. According to research on kids and sports, 20 million out of the 40 million kids who play sports in the US say they have been shouted loudly at or called names while playing sports. Thus, many children think sports are just too aggressive.

Many researchers believe adults, especially parents and coaches whom children usually admire, are the main cause of too much aggression in children's sports. They think children copy aggressive adult behavior that is then further reinforced（加强） through both good and bad feedback(回馈). Often these adults behave aggressively themselves, sending children the message that winning is everything. Children are even taught that hurting other players is acceptable, or are pushed to continue playing even when they are injured.

To solve this problem, parents and coaches should act as better examples for children and teach them better values. They should not just cheer when children win or act aggressively. Instead, they should teach children to enjoy themselves whether they win or not. It is not necessary to knock oneself out to enjoy sports. If people make some basic changes, children might learn to enjoy sports again.
