You have waited 45 minutes for the valuable 10 minutes’ break between classes. But when the bell for the next class rings, you can’t 36 how quickly time has passed.
If you are familiar with this 37 , you’ll know how time flies when you are having fun and 38 when you are bored. Now scientists have 39 a reason why this is the case.
Scans have shown that patterns of activity in the brain 40 according to how we focus on a task. When we are 41 , we concentrate more on how time is passing. And this makes our brains 42 the clock is ticking more slowly.
In an experiment 43 by a French laboratory, 12 volunteers watched an image 44 researchers monitored their brain activity.
The volunteers were told to 45 concentrate on how long an image appeared for, then 46 the color of the image, and thirdly, study both duration and color. The results showed that 47 was more active when the volunteers paid 48 subjects.
It is thought that if the brain is 49 focusing on many aspects of a task, it has to 50 its resources, and pays less attention to the clock. 51 , time passes without us really 52 it, and seems to go quickly. If the brain is not so active, it concentrates its 53 energies on monitoring the passing of time. 54 , time seems to drag.
Next time you feel bored 55 , perhaps you should pay more attention to what the teacher is saying!

(答案→)36-40 CCCAD 41-45 BBDCD 46-50 BDDAD 51-55 CCBBA 解析：【小题1】 C。课间十分钟玩得很开心，时间在不知不觉中就过去了。此处用can’t believe表示对这段时间飞快流逝的惊讶与感叹。【小题2】上文提到的是一种特定的心理场面描写，而不是人所经历的某一件具体的事情，故scene情节,场面；experience经验,经历,阅历。【小题3】根据文中倒数第二段的解释可得知答案。drag拖长，此处指时间过的很慢。【小题4】thought over仔细考虑 ;make up 组成; suggest建议；表明; come up with提出。科学家是以实验为基础进行研究而提出的一种原因。【小题56】联系下文的实验可知，当人的大脑集中于一个任务的多个面时，就变得比较活跃，反之，则变得不那么活跃。所以当大脑所注意的任务不同时，大脑的活动状态是不一样的。【小题6】联系上下文可知，人在比较厌烦或感到无事可做的时候，才觉的时间过得很慢。【小题7】时间过得很慢只是人的一种潜在的意识。【小题8】空格所缺的词做定语，应与前面的experiment构成动宾关系，结合下文进行的实验可知，只有D项符合。B项应改为carried out 。 【小题9】此处用while强调在实验过程中，被实验者与研究人员的任务对比关系。【小题10】根据后面的then; thirdly可得知答案。【小题11】据后文49空后的解释可知，实验的目的是让大脑不停的专注于一个任务的多个方面。【小题12】此处指被研究人员的大脑思维比较活跃。【小题13】结合上文的实验可知，研究人员是让实验者的大脑专注于一个任务的多个方面。【小题14】be busy doing…忙于……为固定搭配；be likely to do…可能做……； be ready to do…准备做……； be sure of / about对……确信。【小题15】联系上下文可知，当大脑专注于一个任务的多个方面时，它的精力就会被分散，因而就转移了对时间的注意。spread 此处为分散。【小题16】此处是上述实验所得出的一个结论。 【小题17】根据后文的 seems to go quickly可知，时间在不知不觉中过去。【小题18】如果大脑不太活跃的时候，就会把相当多的精力集中在计算时间上，right/ proper正确的，恰当的，同义，可排除。enough足够的；full充足的；相当多的。【小题19】本句是根据前面的分析而得出的结论。【小题20】本句与文章第一段相对应，是对第一段在课堂出现的问题的一种解决方法。另外，根据最后一句也可得出答案。
