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。

1．A.guess B．learnC．believe D．doubt答案C[考查语境与动词的辨析。

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。

]2．A.view B．pointC．scene D．experience答案C[考查语境与名词的辨析。

上文提到的是一种特定的心理场面，而不是人所经历的某一件具体的事情，故此处表示如果你对这个场景熟悉的话。

scene意为“情景，场面”。

]3．A.drags B．stopsC．backs D．gains答案A[考查上下文的语境。

根据文中倒数第二段的解释可得知答案。

也可从此处与前面相同的结构推出答案。

drag“过得很慢，拖沓地进行”。

]4．A.thought over B．made upC．came out D．come up with答案D[考查动词短语的辨析。

think over意为“仔细考虑”；make up意为“组成”；come out意为“出现，露出”；come up with意为“找到，提出”。

科学家是以实验为基础进行研究而给出的一种解释。

]5．A.change B．developC．grow D．slow答案A[考查上下文的语境。

联系下文的实验可知，当人的大脑集中于一个任务的多个方面时，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。

故A项符合题意。

]6．A.sleepy B．boredC．excited D．active答案B[考查上下文的语境。

联系上下文可知，人在比较厌烦或感到无事可做的时候，才感觉时间过得很慢。

]7．A.report B．thinkC．decide D．see答案B[考查生活常识。

时间过得很慢只是人的主观感受。

]8．A.produced B．carriedC．tried D．performed答案D[考查语境与动词搭配。

空白处所缺的词作定语，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项若为carried out也是正确答案。

]9．A.so B．whenC．while D．but答案C[考查语境与逻辑关系，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。

]10．A.partly B．quicklyC．slowly D．first答案D[考查上下文的语境。

根据后面的“then...third”可得知答案。

]11．A.remember B．focus onC．forget D．tell apart答案B[考查上下文的语境。

根据下文第29空后的解释可知，实验的目的是让大脑不停地专注于一个任务的多个方面。

]12．A.researchers B．experimentC．clock D．brain答案D[考查语境。

此处指被研究人员的大脑思维比较活跃。

]13．A.much B．manyC．less D．more答案D[考查上下文的语境。

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。

由上文中的“brain was more active”中的more可知，答案为D。

] 14．A.busy B．likelyC．ready D．sure答案A[考查语境与固定短语搭配。

be busy doing...意为“忙于……”，为固定搭配；be likely to do...意为“可能做……”；be ready to do...意为“准备做……”；be sure of/about意为“对……确信”。

答案为A。

]15．A.focus B．gatherC．reach D．spread答案D[考查上下文的语境。

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意为“使分散，使分布”，符合题意。

]16．A.However B．FurthermoreC．Therefore D．Finally答案C[考查语境。

此处是上述实验所得出的一个结论。

]17．A.recognizing B．watchingC．noticing D．counting答案C[考查上下文的语境。

根据此处的语境可知，此处是指不管我们有没有注意时间，时间都在流逝。

]18．A.enough B．fullC．right D．proper答案B[考查语境与形容词的辨析。

right和proper意为“正确的，恰当的”，同义，可排除；enough意为“足够的”，上下文没有相应的语境，可排除；full意为“最大量的，尽量多的”，符合语境。

如果大脑不太活跃的话，就会把大量的精力集中在计算时间的流逝上。

]19．A.In fact B．As a resultC．For example D．Instead of答案B[考查上下文的语境。

本句是根据前面的分析得出的结论。

]20．A.in class B．with workC．in mind D．of lessons答案A[考查上下文的语境。

本句与文章第一段相对应，是对第一段在课堂上出现的问题的一种解决方法。

另外，根据文章最后一句也可得出答案。
