16.Danish scientists studied more than 1,000healthy joggers and non-joggers over a 12-year period.Those who jogged at a steady pace for less than two and a half hours a week were least likely to die in this time.But those who ran more than four hours a week or did no exercise had the highest death rates.Analysing questionnaires filled out by all the people in the study,scientists concluded the ideal pace was about 8km/h and that it was best to jog no more than three times a week or for 2.5hours in total.People who jogged more closely-particularly those who jogged more than three times a week or at a pace of more than11km/h-were as likely to die as those who did no exercise.
Researcher Jacob Louis Marott,from the Frederiksberg Hospital in Copenhagen,said:"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.No exercise recommendations across the world mention an upper limit for safe exercise,but perhaps there is one."
Scientists are not yet sure what is behind this trend-but they say changes to the heart during extreme exercise could contribute.In their report,they suggest:"Long-term strenuous exercise may change pathological (病理的) structure of the heart and arteries (动脉)."
Maureen Talbot,senior cardiac nurse at the British Heart Foundation,said:"This study shows that you don't have to run marathons to keep your heart healthy."
"Light and moderate jogging was found to be more beneficial than being inactive or undertaking strenuous jogging,possibly adding years to your life."
"National guidelines recommend we do 140minutes of moderate-intensity activity a week."
"If it may sound like a lot for you,brisk walking (快走) is also a good exercise.And if you're bit of a couch potato,this is a good place to start.

分析 本文讲述了一项研究,研究结果是,那些慢跑以稳定的速度不超过两个半小时的人,是不会容易去世的.而那些每周跑四小时以上或不做运动的死亡率最高.可见适当的运动才会使人长寿.
解答 61.C.细节理解题.根据文章第一段"But those who ran more than four hours a week or did no exercise had the highest death rates"可知,不锻炼的人的死亡率更高.故选C.
62.A.细节理解题.根据文章第二段的"scientists concluded the ideal pace was about 8km/h and that it was best to jog no more than three times a week or for 2.5 hours in total"可知,每周至少三次每小时8公里的慢跑.故选A.
63.B.词义猜测题.Alight轻的;Bstrong强壮的,强烈的;enough足够的;frequent频繁的.根据前文的they say changes to the heart during extreme exercise could contribute可推测,应是强烈的锻炼才能改善心肺功能.故选B.
64.B.推理预测题.根据文章第三段的No exercise recommendations across the world mention an upper limit for safe exercise,but perhaps there is one排除A;根据文章倒数第三段的Light and moderate jogging was found to be more beneficial than being inactive or undertaking strenuous jogging,possibly adding years to your life排除C;根据文章倒数第二段的National guidelines recommend we do 140 minutes of moderate-intensity activity a week排除D;根据文章第六段的This study shows that you don't have to run marathons to keep your heart healthy可知,马拉松有助于健康是符合题意的.故选B.
65.D.主旨大意题.根据文章 开头提出的论点"Those who jogged at a steady pace for less than two and a half hours a week were least likely to die in this time.But those who ran more than four hours a week or did no exercise had the highest death rates"可知,那些慢跑以稳定的速度不超过两个半小时的人,是不会容易去世的.但那些每周跑四小时以上或不做运动的死亡率最高.下文是对此研究结果的更一步解释.可见本文主要的观点是,慢跑次数太多或者不锻炼对人体健康都不好.故选D.
点评 本文是健康环保类阅读,考查学生的细节理解和推理判断能力.做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确选择.在做推理判断题时不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
