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 __1__ how quickly time has passed.
If you are familiar with this __2__,you'll know how time flies when you are having fun and __3__ when you are bored.Now scientists have __4__ a reason why this is the case.
Scans have shown that patterns of activity in the brain __5__ according to how we focus on a task.When we are __6__,we concentrate more on how time is passing.And this makes us __7__ the clock is ticking more slowly.
In an experiment __8__ by a French laboratory,12 volunteers watched an image __9__ researchers monitored their brain activity.
The volunteers were told to __10__ concentrate on how long an image appeared,then __11__ the color of the image,and third,study both the duration and the color.The results showed that the __12__ was more active when the volunteers paid attention to __13__ subjects.
It is thought that if the brain is __14__ focusing on many aspects of a task,it has to __15__ its resources,and pays less attention to the clock.__16__,time really passes without us __17__ it,and seems to go quickly.If the brain is not so active,it concentrates its __18__ energies on monitoring the passing of time.__19__,time seems to drag.
Next time you feel bored __20__,perhaps you should pay more attention to what the teacher is saying!
【语篇解读】 本文讲述了为什么有时我们感觉一节课时间过得很快,有时过
得很慢,这主要是因为人的大脑对于一个任务的专注程度不同。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.learn
C.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.point
C.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.stops
C.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 up
C.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.develop
C.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.bored
C.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.think
C.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.carried
C.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.when
C.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.quickly
C.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 on
C.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.experiment
C.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.many
C.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.likely
C.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.gather
C.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.Furthermore
C.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.watching
C.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.full
C.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“****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 result
C.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 work
C.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。]
