Question

We all know that exercise is good for your health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer.

   Recently, researchers studied more than 55,000 adults. About a quarter of the adults have a good habit of running. The study found these runners were much healthier than non-runners. In fact, the runners lived, on average（平均）, three years longer than the non-runners.

Running may be good exercise, but it can be difficult on the body. Here are commonly shared ideas among fitness experts（健身专家） to lower the risk of injury（受伤） for people who are new to running.

⊙Take it easy.

Do not run too much, too soon or too fast. Most people get running injuries when they push themselves too hard. The body needs time to get used to increases in distance（里程） or speed.

⊙ Get good running shoes.

There is no single best shoe for every runner. You should find the shoe that offers the best fit and support for your feet. More importantly, you should have a new pair of shoes every 500 to 800 kilometers.

⊙Take good notes.

Take time after each run to write down notes about what you did and how you felt. Look for things that happen again and again. For example, you may find that your knees hurt when you run sometimes. But perhaps you feel great when you have a rest between running days. These notes will help you make the best plan for running.

【解析】运动对我们的健康是有好处的，而且研究者们发现跑步这项运动可以使人们长寿。因此作者建议我们要跑步，并且对如何避免跑步时受伤提了一些建议。

1.细节理解题。根据短文的开头We all know that exercise is good for your health. But some kinds of exercise may be better than others可知，锻炼对我们的健康是有好处的，但是有些类型的锻炼方式比其他的方式要更好。也就是说，不是所有的锻炼方式都是一样好的，故选D。

2.细节理解题。根据短文第二段中The study found these runners were much healthier than non-runners. In fact, the runners lived, on average（平均）, three years longer than the non-runners可知，经常跑步的人比那些不跑步的人要更健康，他们的寿命平均比不跑步的人长三年，由此可知选A。

3.细节理解题。根据短文中Take good notes中These notes will help you make the best plan for running.可知，记笔记可以帮助我们制定符合我们的跑步计划。这句话与B选项的意思相符，比较帮助我们找到适合我们的跑步的方式。故应选B。

4.主旨大意题。根据文中Running may be good exercise可知，跑步是一项很好的运动，而且第二段中作者也提到研究者们发现经常跑步的人比不跑步的人更长寿，作者还分享了一些健身专家们关于在跑步时如何避免受伤的建议。因此作者写这篇文章的主要目的是鼓励更多的人来加入到跑步锻炼中来。故应选D。

点睛：这篇阅读理解是说明文，文章中讲述了跑步这项运动对身体健康的好处。这篇短文的结构很清晰，文章的中心容易把握，做题的时候，要根据题干的要求，在文章中定位答案的具体位置，判断选项，得出答案。第1、2 题题干中已经明确了答案的位置，即第一、二段，因此我们在做题的时候，只需要来细读这两段的内容即可。第4题是主旨大意题，让我们总结作者写这篇短文的目的，这是比较难的题目，我们要从文章的整体去把握，要体会作者的写作意图和态度。A选项错在for the researchers，不是给研究者们提供信息；B选项错在non-runners，不是警告不跑步的人跑步的风险；C选项是迷惑性最大的，帮助跑步者们用科学的方式跑步，根据短文中for people who are new to running.可知，它也是不对的。
