Here's a new warning from health experts: Sitting is deadly. Scientists are increasingly warning that sitting for prolonged periods — even if you also exerci regularly — could be   1 for your health. And it doesn't matter where the sitting takes place — at the office, at school, in the car or before a computer or TV — just the overall number of hours it   2  . Rearch is preliminary, but veral studies   3 people who spend most of their days sitting are more likely to be fat, have a heart attack or even die.In an editorial   4 this week in the British Journal of Sports Medicine, Elin Ekblom-Bak of the Swedish School of Sport and Health Sciences suggested that authorities rethink how they define   5 activity to highlight the dangers of sitting.While health officials have issued guidelines   6 minimum amounts of physical activity, they haven't suggested people try to limit how much time they spend in a ated   7  ."After four hours of sitting, the body starts to nd   8 signals," Ekblom-Bak said. She explained that genes regulating the amount of glucoand fat in the   9 start to shut down.Even for people who   10  , spending long stretches of time sitting at a desk is still harmful. Tim Armstrong, a physical activity expert at the World Health Organization, said people who exerci every day —   11 still spend a lot of time sitting — might get more benefit if that exerci were spread across the day,    12 in a single bout.That wasn't   13 news for Aytekin Can, 31, who works at a London financial company, and spends most of his days sitting    14  a computer. Several evenings a week, Can also teaches jiu jitsu, a Japane martial art  15 wrestling, and also does Thai boxing."I'm sure there are some detrimental   16 of staying still for too long, but I hope that being   17 when I can helps," he said. "I wouldn't want to think the sitting could be   18 dangerous."Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, rearchers found people who sat   19 had a higher death risk, independently of whether or not they exercid.Figures from a US survey in 2003-2004 found Americans spend more than half their time sitting, from working at their desks to sitting in cars.Experts said more rearch is needed to    20 just how much sitting is dangerous, and what might be possible to offt tho effects.(   ) 1.

答案

1-20 ABCDB CDACD CADCB ABDCD

解析

本文说明的是:越来越多的科学家提醒,即使经常锻炼身体,长时间坐着也会对健康产生有害影响。完成此题时要结合日常生活中的常识。1. A长时间坐着也会对健康产生有害(bad)影响,而非好(good)影响,吝啬的(mean),和死的(dead)。2. B 不管你坐在哪里,它都会发生(occurs),而不是做(does),匹配(matches),和死亡(dies)。3. C但已有几项研究显示(suggest),而不是建议(advi),谈论(talk)和说(say)。4. D 在英国《运动医学》杂志上发表的(published)一篇评论文,而绝非是扔掉的(thrown),抓住的(caught),看见的(en)。5. B相关机构应重新考虑如何界定身体(physical)锻炼,以强调久坐的危害。是身体而非生理(biological),心理(psychological)和逻辑(logical)。6. C 卫生官员已发布指南建议(recommending)人们的最低身体活动量,是建议而不是修补(mending),评论(commending)和交流(communicating)。7. D但在一天最多坐(保持坐姿:in a ated position)几个小时的问题上还是个空白,是姿势而非座位(stand),状态(state),和柱子(post)。8. A身体会开始发出有害(harmful)信号,而不是仔细的(careful),完美的(wonderful),和有技巧的(skillful)。9. C此时调节体内(就是身体:body)葡萄糖和脂肪量的基因会开始罢工,而绝不是头(head),胳膊(arm)和脚(foot)。10. D即使对那些经常锻炼(exerci)的人来说,长时间坐着也有害,是锻炼而不是睡觉(sleep),休息(rest)和走路(walk)。11. C对于那些每天锻炼但依然(就是转折:but)有很多时间是处于静坐状态的人来说,是表示转折而不是和(and),因此(so)这样的递进因果关系,更不是然后(then)这样的副词了。12. A如果每天的锻炼可分散进行而不是(rather than)一次集中完成,other than:就是,more than:多于,less than:少于,显得不合适。13. D 这对于艾特金.肯来说不是什么好消息,这儿就是受人欢迎的(welcome)消息,而不是坏的(bad),有害的(harmful),不利(disadvantage)消息。14. C肯每天大部分时间都坐在电脑前(in front of),而不是后面(behind),往后(back)和往前(forward)。15. B不过他每周有几个晚上教授和摔跤相关的(involving)柔术,而不是参考(referring),拿走(taking)和带来(bringing)。16. A我知道长时间坐着不动肯定有害的影响(effects),而不是完美(prefects)和提供(offers),affects是动词:影响,我们这儿要的是名词。17. B但我希望我做的这些运动(就是活跃起来:active)能起到作用,而绝不是不活跃(inactive),互动(interactive)和正面(positive)。18. D我不愿相信坐着会产生这么(也就那么:that)危险的后果,而不是修饰名词的如此(such),少的(little)和得还a连用的多(lot)。19. C长时间坐着(就是坐的较多:more)的人死亡率更高,而根本不是修饰不可数的较少的(less),修饰可数的较少的(fewer),和较远的(further)。20. D 开展更多研究以测算(就是计算出:figure out)每天坐多久会对健康产生威胁,而不是遗漏(leave out),拿出(bring out)和举出(hold out)。
