关于一道英语阅读题 为什么答案是C呢?
Have you eaten too much over the holidays?You should try fidgeting for a while.Those 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) is an important way of burning up calories .
American researchers have found that some people’s squirming (continuously turn your body when nervous) and wigging (move in small movements,especially from side to side) equals several miles of slow running each day.
The scientists,based at the National Institute of Health’s laboratory in Phenix,Arizona,are studying why some people get fat and other stay slim.
In one study 177 people each spent 24 hours in a room in the institute where the amount of energy is 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 foot 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 found that slim women fidget more than fat women,but there was no significant difference in men.Heavy people burn up more energy when they fidget than thin people do.
32.According to the scientists,the reason why some people get fat and other people stay slim is that ____ .
A.thin people burn up less calories than fat people
B.fat people burn up more calories than thin people
C.those who burn up more calories than others will be thinner
D.those who fidget more than others will be thinner
关于一道英语阅读题 为什么答案是C呢?
最后一句:Heavy people burn up more energy
AB直接排除,因果关系反了,要找的成为胖子和瘦子的原因.
D:比别人更经常疲惫的更瘦些(明显不对,这是体质弱)
C的意思是:比别人燃烧更多卡路里的人更瘦些.
所以选C
再问: 这里的fidget应该理解成动来动去,坐立不安
题目的意思是“为什么有些人变胖,有些人保持苗条的身材” 我在纠结C选项的意思应该理解为“那些比别人燃烧更多卡路里的人会比别人瘦”还是“那些比别人燃烧更多卡路里的人会变瘦”? 如果意思是前者的话又解释不通,因为一个胖子燃烧比瘦子多卡路里的情况下还是比瘦子胖。
再答: 看题:why some people get fat and other people stay slim
“一些人变胖而另一些人变瘦的原因是”
题目没有从胖子瘦子说起,所以视为起点相同。原先同样身材的人有的变胖有的变瘦的原因是C,能说通了吧?
