If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.

Scientists in Denmark have been studying over 1,000 joggers and nonjoggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as nonjoggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries (動脈). Over time, this can cause serious injuries.

Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy, jogging a few times a week at a moderate pace is a good strategy. Anything more is just unnecessary, and it may be harmful.”

The implications of this are that moderate forms of exercise such as tai chi, yoga and brisk walking may be better for us than “iron man” events, triathlons and longdistance running and cycling. According to Jacob Louis Marott, another researcher involved in the study，“You don't actually have to do that much to have a good impact on your health.And perhaps you shouldn't actually do too much.”

Answer 1

【答案】

【1】A

【2】C

【3】A

【4】D

【解析】

試題解析：

【1】詞義猜測題。此處指像馬拉松一樣的鍛煉，所以strenuous應(yīng)與hard意思相近，表示“艱苦的，費力的”。regular“定時的”；practical“實用的”；flexible“靈活的”。

【2】寫作目的題。作者在第二段中采用了列數(shù)字的方法，是為了提供支持的證據(jù)，能更有力地說明第一段的研究結(jié)論。

【3】細(xì)節(jié)理解題。根據(jù)第二段的最后兩句“The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries (動脈). Over time, this can cause serious injuries.”可知，劇烈運動會導(dǎo)致心臟和動脈結(jié)構(gòu)發(fā)生變化，從而有損健康。

【4】推理判斷題。根據(jù)最后兩段可知，過度鍛煉不僅沒有必要，而且還可能有害，適當(dāng)?shù)腻憻挄�有助于健康�?/span>
