Question

  You have waited 45 minutes for the valuable 10 minutes' break. But when the bell for the next class rings,you can't believe how quickly time has passed. If you have this experience,you'll know how time flies when you are having fun and drags when you are bored. Now scientists have come up with a reason why this happens.

  They have found that the brain changes its way to work according to how we direct our attention to a task. When we are bored,we pay more attention to how fast time is passing. And this makes our brains think the clock is ticking more slowly.

  Recently some researchers who wanted to understand the conditions carried out an experiment. In the experiment,twelve volunteers watched a picture when researchers monitored (监控) their brain activities.

  The volunteers were told to first notice how long a picture appeared,then the color of the picture,and thirdly,study the both. The results showed that the brains were more active when the volunteers paid attention to more subjects.

  It is thought that if the brain is busy noticing many aspects (方面) of a task,it has to spread its resources,and pays less attention to the clock. Therefore,time seems to go by quickly. If the brain is not so active,it puts its full energy on the passing of time. As a result,time seems to move slowly.

  Next time you feel bored in class,perhaps you should concentrate on what the teacher is saying.

Answer 1

1. A词义猜测题。由题目中的关键词drags ,可回原文定位于第一段。根据第一段中的"you'll know how time flies when you are having fun"可知，当你感到快乐时,就会觉得时间过得很快，那么当你感到无聊时，就自然会觉得时间过得很慢。drags意为"过得慢"，相当于passes slowly。

2. C细节理解题。由题目中的关键词the scientists found ,可回原文定位于第二段。科学家发现，人脑在不同的情况下，工作方式不一样。

3. C细节理解题。由题目中的关键词How... do the experiment ,可回原文定位于第三段。通读第三段内容可知，研究者所做的实验是让志愿者观察一幅图同时监控他们的大脑活动。

4. B细节理解题。由题目中的关键词TRUE，可回原文定位并理解全文。人在集中精力做事时就不会感到无聊。

5. C主旨大意题。由题目中的关键词the best title ,可回原文定位并理解全文。文章主要讲述了研究者通过实验来研究人们感到时间过得快或慢的原因。
