閱讀理解：Have you eaten too much over the holidays? You should try?fidgeting?for a while. Those people around you might not like it, but scratching(moving your nails against a part of your body) and twitching(moving suddenly and quickly when you don'?t want to) are important ways of burning up calories.American researchers have found that some people's squirming(continuously turning your body when nervous) and wiggling(moving in small movements, especially from side to side) equal several miles of slow running each day.The scientists, basing the National Institute of Health's laboratory in Phoenix, Arizona, are studying why some people get fat and others stay slim.In one study, each of 177 people spent 24 hours in a room in the institute where the amount of energy was measured by their oxygen and carbon dioxide levels. By the end of the day, some people had burned up 800 calories in toe-tapping(moving the front part of your feet up and down), finger-drumming(hitting your fingers continuously and lightly against something hard) and other nervous habits. However, others had burned up only 100 calories.The researchers have found that slim women fidget more than fat women, but there is no significant difference among men. Heavy people burn up more energy when they fidget than thin people do.

參考答案：

1、【參考答案】D

［考點(diǎn)］詞語理解題

【精析】D 通讀全文可知，文中提到了很多fidgeting的動作：scratching, twitching, squirming, wiggling, toe-tapping, finger-drumming。根據(jù)第四段第二句“…and other nervous habits.”并結(jié)合常識可知，這些都是人在緊張時做的習(xí)慣動作。由此可推知，fidget意為“煩躁，坐立不安”。四個選項中D項與其意思最接近。A、B兩項只是其中一方面；C項是一種運(yùn)動，均不符合題意。故選D。

2、【參考答案】A［考點(diǎn)］事實細(xì)節(jié)題【精析】A 根據(jù)最后一段最后一句“Heavy people burn up more energy when they fidget than thin people do.”可知，在坐立不安時，胖人比瘦人消耗的能量更多，所以A項正確。根據(jù)第四段最后兩句“…some people had burned up 800 calories…others had burned up only 100 calories.”可知，在坐立不安時，一些人消耗了800卡路里，另一些人只消耗了100卡路里，所以B項不正確。根據(jù)最后一段第一句“The researchers have found that slim women fidget more than fat women, but there is no significant difference among men.”可知，研究人員發(fā)現(xiàn)，苗條的女性比肥胖的女性更容易坐立不安，但在男性中卻沒有明顯的差異，所以C、D兩項不正確。故選A。

3、【參考答案】A

［考點(diǎn)］推理判斷題

【精析】A 根據(jù)第一段最后一句“…scratching…and twitching…are important ways of burning up calories.”，第二段“…squirming…and wiggling…equal several miles of slow running each day.”和第四段第二句“…some people had burned up 800 calories in toe-tapping…finger-drumming…and other nervous habits.”可知，研究人員發(fā)現(xiàn)人在坐立不安時所做的習(xí)慣動作能夠幫助消耗卡路里。由此可推知，科學(xué)家們認(rèn)為人在坐立不安時所做的一些習(xí)慣動作是一種減肥的方法。故選A。

4、【參考答案】D［考點(diǎn)］觀點(diǎn)態(tài)度題【精析】D 通讀全文可知，本文通過研究人員的研究發(fā)現(xiàn)告訴讀者，人在坐立不安時的動作可以減肥，有些人消耗較多的卡路里，而有些人消耗的卡路里比較少；苗條的女性比肥胖的女性更容易坐立不安，但這在男性中卻沒有太大差異；胖的人比瘦的人在坐立不安時消耗的能量更多。文章并沒有表達(dá)作者的個人觀點(diǎn)，所以作者是以客觀的態(tài)度說明研究人員所做的研究及其發(fā)現(xiàn)的。confident:自信的；negative:否定的，消極的；satisfied:滿足的；objective:客觀的。故選D。

5、【參考答案】C

［考點(diǎn)］主旨大意題

【精析】C?通讀全文可知，本文主要講述了研究人員通過研究發(fā)現(xiàn)，人在坐立不安時的習(xí)慣動作能夠消耗卡路里，從而幫助減肥。故選C。
