Question

【题目】 It's free and requires no equipment. Besides, the scenery can be amazing. It's no wonder running is among the world’ s most popular sports. Research suggests running can significantly improve your health. 【1】

Running just once a week, or 50 minutes a week, reduces the risk of death at a given point in time. 【2】 This is good news for those who don't have much time on their hands for exercise. But it shouldn't discourage those who enjoy running longer and more often. We found even "hardcore" running (for example, every day or four hours a week) is beneficial for health. Nor do the benefits necessarily increase by running at high speeds. We found similar benefits for running at any speed between 8 and 13 km/h. It might be that running at your own "most comfortable pace" is the best for your health.

【3】 Running may lead to overuse injuries. These occur as a consequence of repeated mechanical stress on the tissue without enough time for recovery. Sudden death is also likely to happen during exercise, though, this occurs very rarely.

Therefore, for beginning runners, start slow and gradually increase the pace, duration and weekly frequency. Set your aim at 50 minutes a week or more, and run at a comfortable speed.

If you don't like running alone, consider doing it along with others. 【4】 It can be hard to start running, but it shouldn't be too hard. 【5】 There are more than 800 other interesting sports to choose from. The benefits of many other sports (such as swimming, tennis, cycling and aerobics) are comparable to the ones found for running.

A.If you don't like running, don't force it.

B.However, keep it in mind that there are risks as well.

C.It also indicates you needn't run fast or far to gain the benefit.

D.It can increase your motivation and provide a fun social experience.

E.Running may help you live longer but more isn't necessarily better.

F.The benefit doesn't seem to increase or decrease with higher amounts of running.

G.Doing it in many sessions spread across the week brings much more benefits.

Answer 1

【答案】

【1】C

【2】F

【3】B

【4】D

【5】A

【解析】

这是一篇说明文，主要介绍了跑步这一最为大众化的运动。人们无需进行高强度长时间的跑步即可强身健体；跑步亦有风险，“新手”应循序渐进；如果一个人跑步太枯燥，还可叫上他人一起，变成一种有趣的社交活动，亦可尝试世界上丰富多样的其它运动项目。

【1】该空位于首段末尾，而第二段用了整段的篇幅说明了跑步时间无需很长，速度无需很快，即可收获强身健体的“功效”。C选项中needn't run fast or far to gain the benefit（无需跑得很快或很远即可收获益处）是对第二段内容的高度概括，具有承上启下的作用，特别是“fast or far”更是与第二段说明的两大要点准确对应，故选C。

【2】该空前后的内容提到，一周跑个一次或者50分钟即可降低死亡风险，这对没有充裕时间的人来说是个好消息；同时跑得多的人也无需沮丧，因为哪怕是高强度跑步也于健康有益。F项“跑步对健康的益处，似乎不会因跑得更多而增加或减少”是对以上内容的准确概括，而E则说“跑步有益，跑得多未必好”，倾向于不应跑得太多，与下文不符，属干扰项，故选F。

【3】该空位于第三段首句，该段内容话锋一转，中心内容是谈跑步风险，故B项“然而，也要时刻记住跑步也有风险”具有承上启下和概括整段内容的作用，故选B。

【4】该空前一句提到如果不喜欢一个人跑步，可以叫上他人组队跑步，D项中的“增加跑步动力”和“提供一次有趣的社交体验”是组队跑步的两大好处，特别是provide a fun social experience与上句中的doing it along with others准确匹配，可快速锁定答案，故选D。

【5】该空下一句突然提到了其它运动项目：世界上还有其它800种有趣的运动项目，它们也有与跑步类似的“功效”。因此A项中提到“如不喜欢跑步，则不要勉强”符合语境，故选A。
