1.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 1,000joggers and non-joggers for 12years.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 5miles per hour.The research suggests that people who jog more than three times a week or at higher speeds of over 7mph 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,jogging a few times a week at a moderate pace is a good strategy.Anything more is not 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 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".

分析 短文讲述了运动与健康的关系.研究表明,过量的运动和不做运动一样,都对身体不益,过量运动会伤及一个人的心脏和动脉,只有适当的运动才有益于身体健康.像太极,瑜伽之类的温和的运动方式会比三项全能,马拉松长跑等高强度的运动方式更适合人体的健康.
解答 32.A 词义猜测题 hard 耗费体力的;regular 有规律的;practical 实际的;flexible 灵活的.根据文中people who do a very strenuous workout are as likely to die as people who do no exercise at all.可知do a very strenuous workout和 do no exercise 是相对的,所以应该选A.
33.C 推理判断题 第二段列举一些数字是为了证明第一段最后一句的people who do a very strenuous workout are as likely to die as people who do no exercise at all.所以这些数字是为第一段中讲到的事实提供依据的,故选C.
34.A 细节理解题 由第二段中The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries(动脉)可知,过量的运动有害可能是因为它伤害心脏和动脉,所以应该选A.
35.D 推理判断题 根据第三段的意思,过多的和过少的运动都对身体不益,只有适当的运动才有益于身体健康,所以答案选B.
