这样的目的，人们就有必要建立专门的热量实验室。第一段详细地介绍了热量实验

室的有关情况，比如它的外观、尺寸、用途等。选项C的意思是“热量测量室是什

么?”作为第一段的大意最合适，故选C。

24、Paragraph2

标准答案：F

知识点解析：第二段主要讲尼古拉作为一名志愿者，在热量测量室进行了多次试

验，文章说她到这里来的目的主要不是减肥，因为她没有体重问题，而是看看这里

的饮食和活动对她的健身活动如何有益。因为她是跳舞的，她认为通过参加这里的

活动会给自己的工作带来益处。选项F的意思是“她为什么来参加试验?”正好概括

了这段的主旨大意，所以选F。

25、Paragraph3

了针对她安排的实验的详细情况，这与选项B的意思相符，故选氏，

29、Volunteershavetogetpreparedforthetimeinthecalorimeter.

标准答案：C

知识/解析：本题考查的是对阐述文章的主旨事实与细节的了解，以及对上下文之

间的意义关系的理解。此句问的是为什么接受试验者要对在实验室里待上一段时间

36Whichofthefollowingisabenefitofafter-schoolprograms?

A、Theyhelptoavoidcrimeandviolenceduringthattime.

B、Theyhelpyouthsdothingsontheirownduringafter-schoolhours.

C、Theyhelpteensdevelopcaringrelationshipswithclassmates.

D、Theyhelptoreduceriskybehaviorsamongyouths.

标准答案：D

知识点解析:依据是第二段“Studieshavebeendonetofindout...resultedinless

violenceeveninpoorneighborhoods**oA选项中的"avoid(避免)”用在这里不准确,根

据第二段内容课后活动只能减少并没有说彻底避免危险行为及暴力行为的产生，因

此不选A。根据第三段第一句话•,很多活动会安排给学生们在课后参加“，所以他们

并不是ontheirown（独自一人的），因此不选B。根据第三段第二句“…develop

caringrelationshipswitha—dults.“可知，并不是和同学之间，而是和成年人之间形

成良好关系，因此不选C。

37、Whydomanyparentsrefusetouseafter-schoolprograms?

AsTheprogramsarcjustlikechildcareprograms.

B、Theprogramsoffernofreedomtotheirchildren.

C、Theprogramsbringlittlebenefittoparentsandchildren.

D^Theprogramscanbeexpensiveorpoorinquality.

标准答案：D

知识点解析：依据是最后一段的前两句话“…therearcmanyreasonswhysome

parents...orhardtojoiif',根据最后一段第三句"Someolderchildrenandyoungteens

mayrefusetoattendprograms（hatseemliketheyarejustchildcare.“可以判断出,只

是某些学生认为这样的活动类似于childcareprograms因比不喜欢，但并不是家长

们拒绝课后活动项目的原氏。因此不选A。根据最后一段第四句话可知，这些活动

并不是不给孩子们任何自由，故不选B项。C选项和前面第二段所讲的“after­

schoolprogramsresultedinlessviolcncccvcninpoorneighborhoods”矛盾，本身就不

正确，更不是家长们拒绝课后活动的原因。

38.Whatcanweinferfromthepassage?

A^Teenagerstendtoslayattheirfriends?housesfbralongtime.

B、Relationshipswithadultsmaycauseunhealthydevelopmentinyouths.

C、Theafter-schoolprogramscanbeusedfbrmanydifferentkids.

Teenagersdonotliketheafter-schoolprograms.

标准答案：C

知识点解析：根据第四段住第一句话可以得知，除了适合那种放学之后父母都不在

家的孩子外，课后活动项目也同样适用于课后在朋友家打篮球，而家里会有一位父

母或是其他成年人在场的情况，因此可以推断C是正确选项。文章中只说了学生

会在朋友家“hangout"，并没有说“slayfbralonglime”，因此不选A。根据笫三段最

后一■句话”...high-qualityrelationshipswithparentsandotheradults...arcvery

importantforhealthydevelop—mentinyouth.”可以推断和父母亲以及成年人之间的

高质量的关系时于年轻人的健康发展很重要，如果这种关系质量不高，那么可能会

造成年轻人的不健康发展，因此不选B。根据最后一段的第三句话可以得知，只是

某些学生不喜欢这样的课后活动，并非D选项中所说的那么绝对，因此不选D。

39、WhichofthefollowingisNOTtrueaccordingtothepassage?

A、Thegradesofthosechildrenwhoarehomealoneafterschoolaremorelikelyto

suffer.

B、Parentswanttogivetheirchildrenasmuchaspossiblefreedom.

C、Theafter-schoolprogramshelpthestudentstomakeuseofthetimeafterschool.

D^Theafter-schoolprogramsareeffectiveinprotectingmiddleschoolandhighschool

youthsfromriskandharm.

标准答案：B

知识点解析：根据最后一段倒数第二句可知，父母亲不确定到底可以给年龄较长已

经过了托管年龄的孩子多大自由，可以判断父母亲并没打算让孩子们随心所欲，给

他们彻底的自由，因此B选项的内容是不正确的。A选项的依据是第一段最后一

句“…researchsuggeststhatsomeofthesechildrenaremoreatriskofpoorgradesand

riskybehaviors”，C选项的依据是第三段第二句"Inadditiontohelpingyouthsmake

useofafter-schoolhours../',D选项的依据是第三段第一句"After-schoolprograms

canhelptoreducecrimeandviolence...

40、Whichofthefollowingisthebesttitleforthispassage?

A^YouthCrimes

B、After-schoolPrograms

C、ProblemChildren

D、ExtracurricularActivities

标准答案：B

知识点解析：全文都在讲述alier-schoolprograms出现的必要性、作用、适合群体

以及来自家长和学生的反应，因此最佳标题应该是After-schoolPrograms<>

知识点解析：第四段是第三段实验的继续，是该实验的第二阶段。研究人员通过对

志愿者尿样进行化验发现，咖啡因摄入者体内的褪黑激素仅为非咖啡因摄入者的一

半。褪黑激素就是睡眠激素，所以答案应该选D。

标准答案：B

知识点解析：文章结尾谈到，“Ohayon建议爱喝咖啡的人午饭后应该换喝脱咖啡因

咖啡”。另外，整篇文章都在探讨咖啡因影响睡眠的机理，所以，作者大概会同意

“晚饭后不应该喝咖啡”的说法。选项A是一个全称判断，这等于说♦•所有喜欢喝咖

啡的人都比不喝咖啡的人睡觉少“。这不一定，因为如果咖啡适量，喝咖啡的时间

适当，咖啡不会影响睡眠。所以，作者可能不会同意这种说法。根据文章第二段第

二句，选项C是错的。根据文章第二段第一个句子，我们体内的褪黑激素（睡眠激

素）的浓度在我们上床时间前两小时开始上升，而这个时候我们会开始有困意。反

过来说就是，人们并非一有困意就睡觉。所以，选项D不是答案。

46、[Bl]

标准答案：C

知识点解析：空格46后面的句子中出现了一个比较级“lessfirmly"，这说明空格中

也应有这样一个副词。从句意上看，空格后面的句子以转折词but引导，说明该句

与空格中的句子成转折关系。综合考虑，本题选C。

47、[B2]

标准答案：E

知识点角2析：空格47所在段落主要是在谈论20世纪50年代的“反文化”运动给传

统意义卜.的美国男女作用对比带来的影响。选项中只有E项出现了“themovement”

这个词组，所以大致圈定选项E。从上下文来看，选项E实际上是该段中所谈到的

变化的总括，故
