Scientists are increasingly warning that sitting for prolonged periods — even if you also exercise regularly — could be 11 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 12. Research is preliminary, but several studies 13 people who spend most of their days sitting are more likely to be fat, have a heart attack or even die.In an editorial 14 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   15 activity to highlight the dangers of sitting.While health officials have issued guidelines 16 minimum amounts of physical activity, they haven't suggested people try to limit how much time they spend in a seated 17."After four hours of sitting, the body starts to send   18   signals," Ekblom-Bak said. She explained that genes regulating the amount of glucose and fat in the 19 start to shut down.Even for people who 20   , 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 exercise every day — 21 still spend a lot of time sitting — might get more benefit if that exercise were spread across the day, 22 in a single bout.That wasn't 23 news for Aytekin Can, 31, who works at a London financial company, and spends most of his days sitting 24   a computer. Several evenings a week, can also teaches Jiu jitsu, a Japanese martial art 25 wrestling, and also does Thai boxing."I'm sure there are some detrimental 26 of staying still for too long, but I hope that being 27 when I can help," he said. "I wouldn't want to think the sitting could be 28 dangerous."Still, in a study published last year that tracked more than 17,000 Canadians for about a dozen years, researchers found people who sat 29 had a higher death risk, independently of whether or not they exercised.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 research is needed to 30 just how much sitting is dangerous, and what might be possible to offset those effects.11.

A   12. B   13.C   14.D   15. B   16. C   17.D   18.A   19.C   20.D 21.C   22.A   23.D   24.C   25.B    26.A   27.B   28.D   29.C   30.D 【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。11. 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）。12. 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）。13. C但已有几项研究显示(suggest)，而不是建议（advise），谈论（talk）和说（say）。14. 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（seen）。15. 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）。16. 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）。17. D但在一天最多坐(保持坐姿：in a seated 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）。18. 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）。19. 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）。20. D即使对那些经常锻炼（exercise）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）。21. 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。22. 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。23. 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。24. 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）。25. 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）。26. 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。27. 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）。28. 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）。29. 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)。30. 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）。 三、短文改错。【答案】31. studies改成study32. has 改成 is33. kind 改成kinds34. borrowed改成borrow35. a改成the36.their 改成our37.I前面加What38. or改成and39. in去掉40. Have 改成Having【解析】31. studies改成study 考查主谓一致。主语是A large number of students复数形式，故谓语动词用原形。32. has 改成 is 考查there be句型，某地有某物，表存在用there be句型，且后面跟的是a big library单数，故用is。33. kind 改成kinds 考查单复数。我们可以借我们喜欢的不同种类的书，不同种类的是复数，故kind用复数形式。34.borrowed改成borrow 考查时态。全文都是一般现在时，这里也应该用一般现在时，故borrowed改成borrow。35. a改成the 考查冠词。这里的library是上文提到过的，所以用定冠词。36. their 改成our 考查代词。全文都在讲我的学校，用的都是第一人称，所以这里应该用第一人称，故their 改成our。37. I前面加What 考查主语从句引导词。本句的主语应该是个从句，故在I前面加What。38. or改成and 考查连词，come 和fly是两个并列的动词，所以把or改成and。39. in去掉 考查介词。已经有了介词next to,教室在花园旁边，所以in多余，应该去40. Have 改成Having 考查非谓语动词。这里Have classes in such a beautiful environment做伴随状语，且主语we和动词have是主动关系，所以把Have 改成Having。 四、书面表达。We are facing more and more serious challenges from global warming. The ice is melting and the sea level is rising. Coastal cities and their residents are in danger.However，even we ordinary people can do something to help. First，we should start making use of clean energy. For example，we can use solar and wind energy to replace coal and oil. Moreover，we should take public transportation instead of driving cars. This can reduce the emission of carbon dioxide. Finally，we should grow more trees and plants since they can absorb carbon dioxide and other pollutants in the air.Global warming is something everyone needs to be concerned about. It’s time for all of us to do what we can to help protect our earth.                    版权所有：学优高考网(www.gkstk.com)
