知识点解析：该段指出连锁药店MedicineShoppe的一项调查显示：参与调查的一

千多人中有65%的人表示他们曾经吃过过期药，其中一乜以上的人表示吃药时就

已经知道药是过期的，也就是50%以上的人，［C］项正确。

B、theireffectivenesscan'tbeinfluenced

C、theymayaggravatethedisease

D^theymaythreatenone'slife

的time指的就是expirationdate,故选［A］。

3、Wherearemedicationsmoresuitabletobestoredaccordingtothepassage?

A、In(hebathroom.

B、Inthekitchen.

C、Inthebedroom.

D^In(hestudyroom.

标准答案：C

知识点解析：该段前面提到浴室和厨房并不适合保存药物。最后一句说将药品存放

在卧室是不错的选择。可知选［C］。

4、AccordingtoToddCecil,whichformofthemedicationismorelikelytodegrade?

A、Liquid.

B、Pill.

C、Capsule.

D^Powder.

标准答案：A

知识点解析：第二句讲陶德・塞西尔说到任何物质变成溶液形式，会很快分解，而

同样的物质，溶液态的物质分子比固态状的更易起变化。由此可判断液态状的更可

能会分解。其他选项都是固态状的。故选［A］。

C、Theydon'topposepeopletotryexpireddrugs.

标准答案：D

知识点解析：第三句讲到尽管FDA得出88%的药物在过了保质期五年后都没有变

质这一结果，但多数专家认为不值得冒险去吃过期药。由此可推知专家们并不赞成

人们吃过期药。选［D］。

6、Whendrugmanufacturesaskfortheapprovalofnewdrugs,theyaredemandedto

知识点解析：该段第一句话提到FDA要求药品生产商在申请药物认证时，要提交

药品的有效期，［A］项与文意一致，为正确答案。其他几项不是FDA要求药品生产

商做的。注意文中说FDA要求生产商提交的药品有效期要有实时稳定数据为基

础，而不是提交实时稳定数据，故排除［D］项。

A^Theyarenotworthbelieving.

B、Theyareaccuratebutinlackofevidence.

C、Theyarescientificbutalittleinaccurate.

D^Theyarcscientificandprecisecompletely.

标准答案：C

知识点解析：最后两句讲即斯顿认为生产商做测试的结果是科学的，但有点投机取

acontainerwhichis.

标准答案：childproof

知识点解析：文中讲到自己处理这些过期药的方法：把它们装进对孩子来说是安全

11、Whatdoestheauthorthinkofeatingdisorders?

A、Theyaretheresultofaddictions.

B、Theycancausegreatmetaldamage.

C>Theyresultinstarvationofthespirit.

D、Theyarcakindofcancer.

标准答案：B

知识点解析：事实细节题。第一段第三句指出，饮食失调导致的最大伤害是精神上

的，是精神上的癌症，［因项正确.该段第五句指出如同上瘾一样，节食…，由此

看出作者没有将节食看作是一种addiction,排除囚项，©项颠倒了因果关系，是

精神上的匮乏导致了节食而非节食导致精神上的匮乏，“精神上的癌症”体现了节食

对精神上的伤害，并非说节食是一种癌症，故［D］项也不对。

12、Accordingtothepassage,somepeoplegoonadietinorderto.

A、senseakindofspiritstarvation

B、beaddictedtostarvation

C、obtainsomekindofsense

D、remove(hecanceroftheirsoul

标准答案：C

知识点解析：事实细节题。第一段倒数第二句说。就像上瘾一样，一些人通过节食

让伤痛变得麻木，同时获取一种控制、力量以及解脱的感觉。［C］项中的sense是对

原文中的各种具体感觉的概括，所以正确。另外，理解文中restriction的意思”节

食''也是解答本题的关键。

13、Whatdoesthesecondparagraphmainlytalkabout?

A^Themediaadvocateseatingdisorders.

B、Manybonymodelsarcatriskofdeath.

C、Manypeoplefocusoneatingdisorders.

D、Therearemanyincorrectattitudestowardseatingdisorders.

标准答案：D

知识点解析：推理判断题。第二段举了媒体对节食的美化，人们的种种节食举措，

这些都反映了社会存在的对节食的不正确的态度，［D］项正确。其他三项都是表面

的现象，不能概括全段的意思.

14、Theword"whole"(Line8,Para.3)inthepassageistheclosestinmeaningto

A^healthy

B、successful

C、complete

D、full

标准答案：A

知识点解析：语义理解题。whole在的短语是makeherwhole,根据文章内容可知

她一直在医治她的病，想要康复，故这里是“健康的"意思。［A］正确。

15、Fromthelastparagraph,wccanseethattheauthor

A、criticizesthosewhoaremiorexic

B、showssympathytothepeoplewhosufferfromanorexia

C、believesthatanorexiaandbulimiaarcfatal

D^thinksmentaldiseasesareincurable

标准答案：B

知识点解析：观点态度题。最后一段说患厌食症的人只是一个纸做的玩偶，是一个

用硬纸壳剪的纸人。让我们去寻找那些躲藏在虚假表面下的人，然后给她一个拥

抱，那是她所需要的。由此我们可以看出作者对那些患厌食症的人是很同情的，

［B］正确。

A、Tuckis(hebestbusinessschool

B、Salariesforbusinessschoolgraduatesisthehighest

C、manyAsiancountrieshavesetupmorebusinessschools

D、Tuckisoptimisticaboutitsgraduates5employmentrate

标准答案：D

知识点解析：事实细节题。第一段最后一句话说塔克商学院去年在学生毕业的三个

月内就达到了史上最好的就业率，即达到了98%,而现在他们对于刷新这个纪录

信心百倍。由此看出他们对提高就业率很乐观，［D］项正确。文中虽然说塔克商学

院的升学率很高.商学院毕业牛的起薪也猛增但并没有说是最高的.故［A］、［R］错

误，［0项文中没有提及。

17、WhichofthefollowingbeststatesPaulDanos5opinion?

A、Managementeducationisthebesteducationmodel.

B、Businessschoolstudentspreferlearningmajorsubjects.

C、,Manybusinessschoolstudentsdemandtolearnmorethings.

D^Thedownturnofbusinessschoolscontributedtoeconomicdepression.

标准答案：B

知识点解析：推理判断题。第二段保罗・达诺思说，所有认为基本模式不奏效的观

点都是错误的。绝大多数学生说，这是他们最好的教育经历。同时他还说到“我们

的学生要求苛刻，不接受教给他们不相关的东西”，由此推断出学生更愿意学主要

课程(majorsubject),故［B］项正确。|A|项文中未提及；文中说学生要求不接受不相

关的东西，而不是说要接受更多的东西，［C］项错误；第二段的第一句话也否定了

［D］项。

18、Mr.Podolnymayagreethat.

A^studentsarenotsatisfiedwiththeirbusinesscourses

B、MBAlessonsarcdefinitelyunpracticalforstudents

C、studentsaremoreinterestedintheirbusinesscoursesinYalenow

D、itisnotnecessarytoinitiaterenovationinYale

标准答案：C

知识点解析；推理判断题。第四段首句说波多尼先生说，目前，学生们对于他们在

耶鲁的学习表现出了更大的热情，而今年的入学申请也剧增，由此可以看出学生们

现在对耶鲁大学商学院课程更感兴趣。［C］项正确。MBA课程与职业的发展之间的

不相关性日益明显，但这不能因此而全盘否定其实用性，故［B］项错误，另外两项

不符合波多尼先生的观点。

19>Accordingtothepassage,whathaschangedinbusinessschools?

A、Manybusinessschoolshavechangedtheirmanagementmodels.

B、Manybusinessschoolshavegivenrelatedmorallessonsforstudents.

C、Manybusinessschoolshaveintroducedthecase-studymethodofteaching.

D、Manybusinessschoolshavemanagedtomakebusinesseducationmorepractical.

标准答案：B

知识点解析：事实细节题。第五段说大多数商学院新开设「或是加强了道德教育。

由此我们看出［B|项正确。文中没有说管理模式和教育模式的改变，［A］、［C］错

误。文中说变化之一是尝试让商学院的教育更加切合实际，但并未说这种尝试已经

取得成功，［D］项错误。

20、AccordingtothecriticsofearlierMBAs,businessschoolsshould.

A^firethoseprofessorswhoareunqualifiedinteachingbusinesscourses

B、stopteachingusefulthingstostudents

C、fbcusonthepracticabilityofcoursesratherthanacademicstrictness

D、fbcusonfacultymembers'academicdiscipline

标准答案：C

知识点解析：推理判断题。文中倒数第二段说大多数评论家们对于早期的工商管理

硕士课程的评价是，其内容日益抽象和学术化。最后一段又说作为对这种批评的问

应，商学院则是热衷于信奉学术严谨。评论家说，学术严谨现在似乎比教给学生有

用的东西更具优先级别。综合这两句话我们可以得出对早期的工商管理课程的批评

者们认为商学院应更注重实际性。［C］项正确。
