18、语】 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。16A.guess Blearn Cbelieve Ddoubt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cant believe表示对这段时间飞快流逝的惊讶与感叹。17A.view Bpoint Cscene Dexperience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。

19、scene意为“情景，场面”。18A.drags Bstops Cbacks Dgains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”。19A.thought over Bmade upCcame out Dcome 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。20A.change Bdevelop Cgrow Dslow答案

20、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。21A.sleepy Bbored Cexcited Dactive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。22A.report Bthink Cdecide Dsee答案B考查生活常识。时间过得很慢只是人的主观感受。23A.produced Bcarried Ctried Dperformed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e

21、xperiment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。24A.so Bwhen Cwhile Dbut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。25A.partly Bquickly Cslowly Dfirst答案D考查上下文的语境。根据后面的“then.third”可得知答案。26A.remember Bfocus onCforget Dtell 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。27A.resear

22、chers BexperimentCclock Dbrain答案D考查语境。此处指被研究人员的大脑思维比较活跃。28A.much Bmany Cless Dmore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。29A.busy Blikely Cready Dsure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。30A.focus Bgather Crea

23、ch Dspread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。31A.However BFurthermoreCTherefore DFinally答案C考查语境。此处是上述实验所得出的一个结论。32A.recognizing BwatchingCnoticing Dcounting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。33A.enough Bfull Cright Dproper答案B考查语境与形容词的辨析。right

24、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。34A.In fact BAs a resultCFor example DInstead 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。35A.in class Bwith workCin mind Dof 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。.阅读理解(共5
