Question

    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.

【解析】

这是一篇说明文。文章主要说明了一项研究表明，经常打网球可以帮助人们避免死亡，但踢足球、打橄榄球和跑步可能无法帮助人们长寿。文章说明了研究过程，以及研究人员还发现，从事球拍类运动可使心脏死亡的风险降低56%，其他专家对此有不同的看法。

1.细节理解题。根据第一段中Playing tennis regularly could help keep people off death, but football, rugby and running may not help people to live longer, a study suggests.可知，一项研究表明，经常打网球可以帮助人们避免死亡，但踢足球、打橄榄球和跑步可能无法帮助人们长寿。由此可知，橄榄球无法帮助人们长寿。故选C。

2.细节理解题。根据第三段Scientists say the difference may lie in the social aspect which goes alongside sports like tennis and squash, 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.可知，科学家们说，区别可能在于社交方面，它和网球、壁球等运动一样，经常涉及俱乐部和有组织的运动之外的活动。这意味着人们通常有更大的社交网络，并倾向于在以后的生活中保持活动，这两者都被证明对健康有好处。对比选项可知，根据这项研究，从事体操并加入一个俱乐部对保持健康有很大的影响。故选C。

3.细节理解题。根据第三段中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.可知，这意味着人们通常有更大的社交网络，并倾向于在以后的生活中保持活动，这两者都被证明对健康有好处。由此可知，社交网络对人们的健康更重要。故选A。

4.主旨大意题。根据第一段中Playing tennis regularly could help keep people off death, but football, rugby and running may not help people to live longer, a study suggests.可知，一项研究表明，经常打网球可以帮助人们避免死亡，但踢足球、打橄榄球和跑步可能无法帮助人们长寿。结合文章主要说明了一项研究表明，经常打网球可以帮助人们避免死亡，但踢足球、打橄榄球和跑步可能无法帮助人们长寿。文章说明了研究过程，以及研究人员还发现，从事球拍类运动可使心脏死亡的风险降低56%，其他专家对此有不同的看法。故选B。
