Question

【題目】 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 (幔跑者)and non - joggers for 12 years. The death rates from the sample group indicate that people who jog at a proper 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 non - joggers. 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(壽命)，jogging a few times a week at a proper pace is a good strategy. Anything more is not just unnecessary, and it may be harmful. “

The implications (暗示 ) of this are that moderate forms of exercise such as tai chi, yoga and walking may be better for us than “iron man events, triathlons and long - distance 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”.

A.regularB.hardC.practicalD.flexible

【2】The author presents some figures in Paragraph 2 to_______ .

A.suggest giving up joggingB.show risks of doing sports

【4】What can be inferred from the text?

Answer 1

【答案】

【1】B

【2】C

【3】A

【4】D

【解析】

本文是議論文。研究表明那些從事的劇烈運動的人和根本不做運動的人死亡概率一樣，這是因為劇烈運動會損害我們的心臟和動脈。適度的運動才有助于我們的健康。

【1】詞句猜測題。第一段If you think that running marathons will help you live a long and healthy life, new research may come as a shock可知，人們一般認為馬拉松會幫助我們過上健康長壽的生活，但新的研究結果不是這樣。那些從事的strenuous workout人和根本不做運動的人死亡可能性一樣�？梢酝茰y“running marathons”是屬于“strenuous 運動”。再根據(jù)第二段because strenuous exercise causes structural changes to the heart and arteries可推測，strenuous exercise是指劇烈運動。 strenuous意為“高強度的，劇烈的，強烈的”。故選B項。

【2】推理判斷題。第二段中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 non- joggers（研究表明每周慢跑超過三次或時速超過7英里的人死亡率與非慢跑者相同），呈現(xiàn)研究數(shù)據(jù)提供證據(jù)，證明文章第一段提出的觀點：做非常劇烈運動的人和根本不做運動的人死亡可能性一樣。故選C項。

【3】細節(jié)理解題。根據(jù)第二段最后一句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（科學家們認為這是因為劇烈運動會導致心臟和動脈的結構改變。隨著時間的推移，這會造成嚴重的傷害）可知，運動過度可能會損傷我們的心臟和動脈。故選A項。

【4】推理判斷題。根據(jù)第3段Anything more is not just unnecessary, and it may be harmful 和第4段Jacob Louis Marott 的觀點And perhaps you shouldn’t actually do too much可知，如果目標是降低死亡風險和延長壽命，以適當?shù)乃俣让恐苈�跑幾次是合適的，不應該做太多的運動。適度的運動才對我們的健康有好處。故選D項。
