Question

【题目】 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(动脉). 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(寿命)，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

【3】According to the scientists, why is too much exercise harmful?

A.It may injure the heart and arteries.B.It can make the body tired out.

C.It will bring much pressure.D.It consumes too much energy.

【4】What can be inferred from the text?

A.No exercise at all is the best choice.B.More exercise means a healthier life.

C.Marathons runners are least likely to die.D.Proper exercise contributes to good health.

Answer 1

【答案】

【1】B

【2】C

【3】A

【4】D

【解析】

本文是议论文。研究表明那些从事的剧烈运动的人和根本不做运动的人死亡概率一样，这是因为剧烈运动会损害我们的心脏和动脉。适度的运动才有助于我们的健康。

【1】词句猜测题。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，人们一般认为马拉松会帮助我们过上健康长寿的生活，但新的研究结果不是这样。那些从事的strenuous workout人和根本不做运动的人死亡可能性一样。可以推测“running marathons”是属于“strenuous 运动”。再根据第二段because strenuous exercise causes structural changes to the heart and arteries可推测，strenuous exercise是指剧烈运动。 strenuous意为“高强度的，剧烈的，强烈的”。故选B项。

【2】推理判断题。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过三次或时速超过7英里的人死亡率与非慢跑者相同），呈现研究数据提供证据，证明文章第一段提出的观点：做非常剧烈运动的人和根本不做运动的人死亡可能性一样。故选C项。

【3】细节理解题。根据第二段最后一句The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉). Over time, this can cause serious injuries（科学家们认为这是因为剧烈运动会导致心脏和动脉的结构改变。随着时间的推移，这会造成严重的伤害）可知，运动过度可能会损伤我们的心脏和动脉。故选A项。

【4】推理判断题。根据第3段Anything more is not just unnecessary, and it may be harmful 和第4段Jacob Louis Marott 的观点And perhaps you shouldn’t actually do too much可知，如果目标是降低死亡风险和延长寿命，以适当的速度每周慢跑几次是合适的，不应该做太多的运动。适度的运动才对我们的健康有好处。故选D项。
