作者: 蜂鸣 时间: 2010-6-1 22:06 标题: GMAT考试 CR新题黄金80题

下载详见http://forum.topway.org/viewthread.php?tid=208626&extra=

从2003-2006年逻辑机经1000多道题的总结,我大概总结出GMAC出题的一些规律,希望和大家一起探讨与分享.
1 GMAT CR有部分高频题目,这些题目每年都会出,而且从03-06年每年都会出现,每年的频率会高于5次.(指不同月份,即一年至少会有5个月出现)
2 虽然GMAT从2006年换了东家,但是题库基本没有改变, 每年只是有部分新题增加,增加新题百分比不高于20%. 往年高频题重复率仍然很高.
3 从06年来看,今年的高频题多出自于2003年的高频题目.
4 不同年份相同月份其实重复出题率不高(所以大家没有必要看每年相同年月的了), 同一年高频题重复率很高.(更应关注当年的高频题目)
5 GWD上的题目几乎都是高频题目,我已经把GWD上每年出现的高频题目贴出来了,不过希望大家在复习CR时最好把GWD上每道题目都弄明白.
我把高频题目贴到了下面,尽量囊括所有的高频题目,相信看完后会更加清醒GMAC的出题思路.

感谢：swords_lan的分类整理！

1. 1 有动物园那题
[version 1]对动物的过敏,动物园的工人有30%的患病率而普通的接触宠物人的患病率更高问加强实在找不出来答案了选了一个"工人有的人不穿防护服"
动物园的工人由于有antibody 有了抗病能力
动物园的工人有保护措施普通的接触宠物人没有
[version 2]几经考量我选了A因长期接触动物引起的过敏症的动物园工人可以换工作
我的理解是言外之意就是他们换了工作就不再有这种过敏症了而一般有这种过敏症换不换工作都不可能改变所占的比例
[version 3]在动物园工作人员中因长期接触动物引起的过敏症的人有30%而专家认为general population中感染因长期接触动物引起的过敏症的人有的甚至远远超过30%substantially more问怎样解释这个现象
[version 4]人和动物长久接触有可能会感染某疾病动物园的职员有30%受感染而专家们说普通人群中受感率会更高大于30%问解释我选动物园职员受感染会转职觉得也不太对但其它好象更不对
[version 5]1100People who have spent a lot of time in contact with animals often develop animal-induced allergies, some of them quite serious. In a survey of current employees in major zoos, about 30 percent had animal-induced allergies. Based on this sample, experts conclude that among members of the general population who have spent a similarly large amount of time in close contact with animals, the percentage with animal-induced allergies is not 30 percent but substantially more.
Which of the following, if true, provides the strongest grounds for the experts’ conclusion?
A. A zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation.
B.    A zoo employee is more likely than a person in the general population to keep one or more animal pets at home
C.    The percentage of the general population whose level of exposure to animals matches that of a zoo employee is quite small.
D. Exposure to domestic pets is, on the whole, less likely to cause animal-induced allergy than exposure to many of the animals kept in zoos.
E.    Zoo employees seldom wear protective gear when they handle animals in their care.

2. 5 火灾问题
[版本一]某调查显示火灾多发生在用电话报警的地方那些装了自动报警装置的地方火灾少所以消防局认为居民应该装自动报警装置而不是电话装置Weaken: 选接警的电话公司和消防局在一起办公可以更快速的反应
weaken选电话报警会告诉地点什么的（GWD）
[版本二]一个地方采用某种方式家庭报警系统有人说虽然这个系统好,但总有误报的现象,浪费人力物力.所以为了减少这一现象有人提出采用对那些误报的家庭FINE.问支持选项 1很多城市也用这个系统 2这个城市以后要更多的使用这系统 3现在好多家庭都没有花时间好好学习怎样使用
[版本二]家庭警报系统因为家庭报警系统经常发出错误的警报“（就是有人故意的）所以导致警力资源的浪费，所以现在经常有时候对那些经常发出错误警报的家庭不于理睬了，但是这样会降低对居民的保护程度，为了加强保护但是不浪费资源，政府要对那些发出错误警报的家庭给予FINE，问削弱计划的成功性。我选了那个，这样为使得很多家庭由于害怕罚款而变得DEACTIVE ABOUT THE SYSTEM。
[版本三]报火警的盒子经常误报，而且大多数人有电话，所以应该拆除。问support. key：电话可以提供比火警盒更多的信息（og中这就是提干中的一个条件）
[版本四]有一个地区消防队经常接到从非家庭电话处打来的错误报告，因为错误的报告就会占用消防队的资源，影响了对其它真正火灾事故的响应速度。然后有人建议把大街上的警报装置拆掉，这样也不会影响消防队的工作效率。问支持选项，我选的是大街上许多公用电话都已经年久失修不能使用了(选完以后觉得怪怪的，但是其它选项更不搭界，大家不要被我误导)。

3. 6 警察局问题
[version 1]自从某市警察局采用了什么政策以后这个市的犯罪率下降了很多.警察局长说是因为采取了这个政策的原因.但是反对者们说这个时期全国的犯罪率都下降了很多.因此这个市的犯罪率下降不是采取了这个政策的缘故.警察局长指出恰恰是因为全国大部份城市都效仿这个市采取了相似的政策才使得全国的犯罪率下降了很多
1支持反对者结论的论据
2反对反对者的论据
[version 2] BF, 警察局长说要采用新的政策因为去年用了新的政策后本市犯罪率大幅下降他又说有人反对该提议It is objected by someone that there is overall decrease in crime rate in last 3 years throughout the countryand that 好像说应为全国犯罪率下降所以本市犯罪率下降不是由于新的政策这段也可能是别的意思没太读懂But if we implement the new policy, it will further decrease the all countrys crime rate, include that of our city.问两段作用
1是支持反对者结论的论据
2反对反对者的论据

4. 16 a kind of bird is decreasing when a place began to construct a community. the reason is the construction destroy a kind of tree which the bird uses it to build nest. But after 1-2 years' construction, the number of the bird began to increase. Ask for explanation ( I chose after 1-2 years, the community is build up and some more high sign appear in the community, so the bird uses the sign to build nest)

1) 邻居没有使用这个垃圾堆；2) 和尚严格执行寺规。作者选了2。
[版本2]14世纪僧侣可以吃鱼，不能吃肉。考古学家挖掘一处14世纪修道院遗址是发现鱼骨头残骸很少，从而得出结论当时僧侣很少吃鱼。问假设？应选在当地的环境下, 鱼骨头不会比XX DECOMPOSE得更快.
[版本3]说14世纪僧侣可以吃鱼，不能吃肉。考古学家挖掘一处14世纪修道院遗址是发现鱼骨头残骸很少而XX很多，从而得出结论当时僧侣很少吃鱼。问假设？

8. 23 Boldface: 科学家40岁的那一道。
[版本1]科学家过了40就不creative . 但有证据证明有很多科学家过了40 还能remain creative,但是这些科学家过了40还能creative 的原因是他们入行的时间向后推迟了. 前一句是反对作者观点的证据,后一句是作者补充支持的原因.
[版本2] 有一种理论认为科学家到四十岁以后就很难出成果的原因在于他们的创造性在四十岁以后开始消退了；另外一种理论认为，不出成果的原因是科学家在四十岁以前把可以出成果的机遇都研究遍了，问支持后一种理论的选项。我选的是如果某个人比较晚的进入科学研究领域，四十岁后出了成果。

9. 26[版本1]在一个地区医院护士与病人的比例为1：6，而一条例规定必须为1：5。所以当地医院只能到周围地区招护士。问削弱？（我选了医院可以通过减少病人住院时间来减少此比例）
[版本2]说现在1个护士照顾6个病人, 现在想多招护士,因为该省护士少,所以要考虑去外省招,问strengthen.记的有2个选项，一个说现在的护士已经满负荷工作（对的），另一个是现在已经有很多护士是外省的
[版本3] 问weaken，选择答案中有，那个州规定了不允许雇用外州的护士。
[版本4] The nurse to patient is 1:6, but the government want to change to 1:5. So clearly the hospital will hire more nurse from other province.
Strengthen: Some nurse feel there are too many patient and leave the job.
(I believe this answer is correct because it means the nurse has already work to their full load so the hospital need to hire new one.)
[版本5] 1029医院原来是1个护士护理6各病人。现在是1个护理5个，结论是由于不会增加新的护士，所以人手会不够 weaken The answer is to increase the turnover rates of patients so not as many people need to be taken care of by the nurses.

10. √35.甲公司和乙公司都生产某种同样的机器零件，该零件的市场需求量的波动较大，因此他们选择雇佣了很多按小时付费的工人。去年，甲乙两公司雇佣了相同数目小时功。但是甲公司的劳动力总成本比乙公司高很多，因此甲公司工人工资的rate比乙公司高。问假设。我选的是：对于加班加点而言，公司付给工人的工资比平时的正常工资要高许多，几乎差不多在甲乙两家公司之间。（原文直译）。

[版本3]my key：technique 让美国牛的肉张的快

12. [版本1] 54. A国,地产rice一直正好能自给自足, 但且预期人口将在今后几年有大幅增长,且A国的ric种植面积无变化,且亩产也没变,=>A将要开始进口rice了. 问假设?
个人选了A. A国的人均RICE consumption不会下降
[版本2] 1010，就是某某地方的人吃CORN和肉，每一肉需要一定的CORN生产，两种东西产量不变，但PER CAPITAL上升了，如果消费水平不变的话，可以推出那种结论：答案：该地方将进口其中的一种或全部都进口。
[版本3] 1109题目中有提到玉米及另外两种食物是人类的主要粮食，但是由于消费增大，而土地面积不变，所以需要政府投资更多的钱来提高产量,问评价

13. √67 [版本1]boldface:很长：讲某种星体撞击行星v，用某种方法考察碎片的大小。（划线）行星v的大气层出现sulfur。所以碎片很大，因为（划线）碎片中没有sulfur.(言外之意是sulfur是从行星v表面弹起来的)。我选的是两者都是对结论支持的证据
[版本2] boldface “ to determine the largeness of fragment, sulfur in the atmosphere but not in the fragment, the fragment is too big to be totally burned”
[版本3] 764BF好象说彗星的。两黑体是彗星碎片里有某东西。但是观察家说彗星本来不应该有的，形成的原因是云。现在彗星有了这东西以后就。。。。最后一句 it is likely that…,我觉得很明显最后一句是main conclusion, 所以2个BF是都是支持，或者是MC的证据。
[版本4] 929BOLDFACE, 大概题意是说怎么判断comet的fragment size呢，一把是没有办法册，可是有某种analysis 能测到大气层外的sulfur，一般情况下sulfur是不会到大气外边的，可是呢现在有了就说明这个comet fragment是大到一定size to penetrate the atmosphere layer，这个SULFER就leak到大气外了。

14. 79通常在餐馆，付现金的客人比用信用卡的客人给的小费要多。科学家却认为，因为使用信用卡可使人意识到自己拥有超过自己实际拥有现金的购买力，因而使用信用卡可以使顾客更愿意花更多的钱。问支持科学家论点的证据？有两个混淆选项：A，上述调查中，所有用现金支付的客人都没有信用卡。B，实验表明，在某餐馆，顾客仅仅因为看到帐单上显示了某一信用卡公司的标志，就更愿意用该信用卡付帐。（GWD）

15. 82电脑密码可以让机密信息得以很好保存。但是很多职员为了好记，都将自己的生日设为密码，这就给密码的保密性增加了不可靠因素。所以，为了更好的提高密码的保密性，应该将随机选定的密码分配给职员。WEAKEN项：为了记住这些随机选定的密码，职员有可能将其记在显眼的位置上。（GWD）

16. [版本1]  111海边停车场罚款，10块钱的那道。旅游胜地游客乱停车，管理者让大家停到离海滩较远的停车场去收费每天10块，但游人们不遵守纪律，市长决定用罚款解决问题，问削弱市长决定的选项，我选市长推行的罚款政策对不遵守纪律的车罚款是10块
[版本2] 766海滩边上的公路总是有非法停车，因为不少游客停下来看风景。而停车场距离海滩比较远，而且 $10。政府为改善，准备开始对乱停的人开罚单。政府认为这样就能改善状况。问政府的目的可能无法达到。建议选，罚款也只有10块钱。

17. 112鲸鱼在淡水和海水的题，选离岸很远的石头上没有化石
[版本1]鲸鱼本来是生在淡水胡里的，但在某年的化石理发现，鲸鱼生活在咸水里，他们develop to adapt to the salty water.这样可以推断，生活在咸水里的鲸鱼must have had to go to fresh lake frequently!问infer.
1。海水淹没了陆地
2。在发现那块化石之前，其他能证明在陆地湖里的鲸鱼化石是不会被发现的
3。海水慢慢流入了内陆湖；其他选项肯定排除
[版本2]鲸鱼本来是生活在淡水里的，但通过某化石发现，有鲸鱼生活在咸水里，所以推断，此鲸鱼一定是频繁地回淡水中喝水。问：infer?
A.无法发现其它的鲸鱼化石；B海水淹没了陆地；E. 海水流入了淡水。
在发现那块化石之前，其他能证明在陆地湖里的鲸鱼化石是不会被发现的
答：在50 million 年前的一个与内陆有大面积海域相隔的小岛上不可能发现这种有**##的动物的化石
答：50M-60M之间，它们无法跨越宽的海洋，所以，以前离淡水远的海洋，变成大陆后，不会有鲸鱼的化石。（GWD）
[版本3] 393 Whales originaled in freshwater lakes and rivers of ancient asia about 60million years ago。 Not until about 10 million years later did species of whales develop 专门kidneys enabling them to drink salt water. Although fossil evidence shows that some early whale species that lack salt kidney sometimes frequently swam in earth's saltwater oceans, thest species must have to return frequently to freshwater river to drink.1. fossiles of whale species different from between 60 million and 50 million years ago will not be found to continents that were at times sperated from ancient asia by wide expanse of ocean.2. among fossiles from later than 55 million ago, none are fossile of whale species sperated the drink only fresh water.3.Fossiles of whale drank fresh water will not be found in close proximity to fossile of whale speices than drank salt water.4. between 50 and 60 million years ago, fresh water lake and river on which whale originate were invade gradually by salt water. answer:1 （GWD）

18. √[版本1] 115吃饭洗手：吃饭前洗手。因为洗手水温度不高，不足以杀死污染食物的细菌，因而洗手对减少细菌污染食物误作用。问：Assumption
[版本2]  741normally people use water to wash hand before lunch, but because too short a time, can not kill the bacteria. So it is no use to wash hand before lunch. Ask assumptionanswer: foam, soup can not kill the bacteria

19. [版本1] 127以前用于治疗某种传染病的药是A和B。这两种药的疗程是7天，但由于很多人服药3天后就停药了，这些人中很多再次被传染。现在发明了一种新的药C，这种的疗程只有3天。所以,让患者服用新药再次被传染的机会比服用旧药低。
问：哪项支持结论?
A, 新药虽然疗程短,但价格和旧药相同.
B, 那些对A过敏的患者,对C也过敏.
D, 已经有一些医生开处方时,给患者开新药.
E, 不管新药,旧药,大多数患者在服用3天后病都会好.  （GWD）
[版本2] 1106TT-9-Q13:The traditional treatment of step infections has been a seven-day course of antibiotics, either penicillin or erythromycin.  However, since many patients stop taking those drugs within three days, reinfection is commonin cases where those drugs are prescribed.  A new antibiotic requires only a three-day course of treatment.  Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed.
Which of the following, if true, most strengthens the argument?
A Some of the people who are allergic to penicillin are likely to be allergic to the new antibiotic.
B A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin.
C The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep.
D Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections.
E Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days.

20. √131Two bridges: A is in renovation so no payment needed to pass it. Therefore, the toll fee of B should be increased to compensate the loss since majority of people use bridge B and ....(to continue)
My answer: It is inconvenient for people to switch between the bridges.
有一个岛，西部只有一座桥，交通堵塞，政府想建一座东桥，以缓解压力，问weaken
我选：在西桥旁边在建一座桥，比东桥省钱
某岛是个东西向长条形，和某大城市的beach平行，现在在岛的西部有一桥，结果发现去东部的vacationer会遇到两个问题：开车距离太长；会造成交通堵塞。所以有人提出一个建议，在岛的东端也造一座桥，可以解决这些问题。问weaken;答案很混淆，我最后还是选了机井里的e, 说在西部造另一座桥的cost比造东桥低；但我觉得这个答案不足以weaken论点，因为论点中说两个问题，并未涉及cost,而在西面造另一座桥不能改变开车距离长这个问题。但是由于时间紧迫，就选了这个。记得另外有个奇怪选项是说在非vacation时间，根本就没有这种问题。大家判断看看。

21. 137解释现象。一种小螃蟹，幼年的时候挖坑，一种东东爬到它的背上。长大了就能够站在湍急的水中，而不用挖坑，这种东东也很少在它背上。然而，在一个水流非常不湍急的地方，这种小螃蟹不用怎么挖坑，那种东东数目也很少。
科学家发现某种有shell的生活在beach上的东东的shell上有一种寄生东东，带壳的小东东身体较弱，需要在beach上挖洞burrow 以躲避猛烈的tides，研究发现带壳的小东东壳上的寄生东东比带壳的adult东东要来得少，科学家得出结论带壳的小东东躲在burrow里使寄生东东不容易寄生在小东东的壳上，研究又发现在weak tide的beach上带壳的小东东壳上的寄生东东并没有significant increase 。
小东东在未发育完以前每年要换好几个壳！
（so 寄生的东东不能在带壳的小东东壳上accumulate，还没等你significant increase他那边已经换壳了！） (GWD)

22. 138洗衣机，厂家说新的型号的洗衣机更省能源，所以省电，可以根据实际测试，新型号的洗衣机每次洗一个Full Load所用电力比老型号的洗衣机要多。这是怎么回事呢，答案里面说，新型号的洗衣机每个Full Load所装载的衣物远远多于旧型号的洗衣机，言外之意就是，原来用旧型号的洗衣机洗十次的衣物，这下用新型号的洗衣机一次就洗完了，那么即使新型号的洗衣机洗一次衣物花费了三倍于旧型号的洗衣机所用的电力，总体来说洗的次数少了，所以还是省电了。

23. [版本1] 223机场拥挤，从东边出口起飞的飞机占60%，从西边出口起飞的飞机占40%。为了减轻交通堵塞，管理人员想建在东边建新的出口以缓解压力，问evaluation 我选：东边起飞的飞机和西边起飞的飞机的每架飞机是否载客一样。
[版本2] 243一个机场东面和西面都有通道，东面航班的旅客流量占60％，西面的占40％。于是建议：在东面再建造一个通道。Evaluation！我选：比较两个通道的旅客流量中中转旅客的比例。这里的中转旅客指的是在这个机场转机的人。注意点：原题目里面说的通道，指的是进出机场的通道。
[版本3] 987为了要提高efficiency，机场要建railroad，然后可能有两个entrance，发现60%的旅客航班到达A所以应该建在A，是什么assumption 答案到那里的不是转机旅客

24. 230某沿海５年前大污染，当年９０％以上的海龟蛋都没有孵化．环境学家预测将对未来的海龟数目有大影响．但近几年来发现海龟数目是上升的，所以环境学家的预测是错误的．问weaken．海龟要到１０岁以后才会来产蛋．应为说明这个危害要到１０年以后才明显的发生；１０年以后产蛋的就会下降了．注意，文章只是说海龟蛋没孵化而非海龟都死光了．

25. 237有一种海藻产生的毒素可以使海龟长瘤，使用化肥后海龟长瘤的更多了。一般认为农药使海龟的免疫力下降了。问削弱。答案是化肥使海藻长得更茂盛了。

26. √240有一题说中世纪（还是罗马时期，不记得了）的文献中记载商业船队海难的资料很少，but当时的商船都是沿着地中海海岸航行的，所以事故都是因为触礁，很少船航行在海的中间，问削弱：1当时往来地中海的重要港口的路线就有要穿过海中心的。2答案中还有有记载事故发生在海中心的。

27. [版本1] 244有一座吊桥，有船过的时候升起来，现在为了解决交通问题，打算重建一座新的大桥，能让给多的车辆通行，这作新的大桥的跨度很大，有桥墩支撑的拱桥高度足够绝大多数的船只通行。问这个计划不可能实现的原因。答：绝大多数船只的宽度大于桥墩之间的宽度。
[版本2] 907有个什么drawbridge就是类似于吊桥,可以吊起来让比较高的船通过.某城市为了减少吊桥对桥上汽车交通的影响决定修个更高的drawbridge 这样不用吊起桥船也能通过了. 问WEAKEN选:换了更高的桥,更高的船也就往这个港口跑了
[版本3] 992某城市有一座可升降的桥，在巨轮通过时，需要被lift，让轮船通过，这样会阻碍桥上汽车通行。现在该市要造一座新桥，柱子之间的距离比老桥宽，高度也比老桥更高，问“造新桥可以改善汽车通行”的削弱。--我选：新桥的车流量是老桥的两倍。

28. √245有题是说Marco Polo文献没有提到长城，而因为长城在中国极为重要，去过的人都会提到，所以断定他没到中国的。问评价答案是：It is unlikely that the author of the books eliminated as a naïve overstatement of the Marco Polo’s description of Great Wall.

29. 253boldface[版本1] :保护环境的某个组织想通过从农民手中将土地买过来的方式，来保护那些有可能被开发商使用的土地。但是这个计划不和逻辑。(But this plan is ill logical.)因为第一，农民总是将土地卖给出价高的人。而开发商显然出价比较高。第二，农民只有在土地没有办法耕种的时候才会卖。而土地要能够耕种，就必须要现代化。所以，环境保护组织应该才有这样的政策：帮助农民完成现代化，这样才可以保护土地不被开发商利用。问第二句话和最后一句话的作用。

30. [版本1] 327 version1.关于阑尾炎的，说他有时候致命，所以现在一般都采取切除的办法，但是有些时候切除手术是不必要的。一种新的test出现了，可以使误诊率减小到2%，医生因此可以避免不必要的切除手术，但是，（后面一句没看懂），因为什么？填空
[版本2] Which of the following most logically completes the passage Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed. The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases. A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses. Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since________________ a: the patients who are correctly diagnosed with this test as not having appendicitis invariably having medical conditions that are much less serious than appendicitis b the misdiagnoses produced by this test are always instances of attributing appendicitis to someone who does not, in fact, have it c: all of the patients who are diagnosed with this test as having appendicitis do, in fact, have appendicitis d: every patient who is diagnosed with this test as having appendicitis has more than one of the symptoms generally associated with appendicitis e :the only patients who are misdiagnosed using this test are patients who lack one or more of the symptoms that are generally associated with appendicitis

32. 346 A recent poll found that over 80 percent of the residents of Nalmed Province favored a massive expansion of the commuter rail system as a means of significantly easing congestion on the province's highways and were willing to help pay for the expansion through an increase in their taxes. nevertheless, the poll results indicate that expansion of the rail system, if successfully completed, would be unlikely to achieve its goal of easing congestion, because______ A. most people in favor of expanding the rail system reported less congestion during their highway commute as the primary benefit they would experience B of the less than 20 percent of residents not counted as favoring the expansion, about half claimed to have no opinion one way or the other C the twice-daily periods of peak congestion caused by people commuting in cars have grown from about an hour each to almost two and a half hours each in the past 20 years D expanding the commuter rail system will require the construction of dozens of miles of new railed E the proposed expansion to commuter rail system will make it possible for some people who both live and work at suburban locations to commute by rail.

33. 359一般家用电器在不使用时是不会耗电的，但有的微波炉有BUILD-IN CLOCK，会在电器关着时仍然耗电。所以，有BUILD-CLOCK 微波炉家庭的年均用电量要比有一般微波炉家庭的年均用电量大。ASSUMPTION

34. 361蝙蝠一般栖息在很深的洞，那里温度很底，但是蝙蝠吃的虫子一般在晚间温度高是才会出来。温度高，气压就底，而气压在洞里洞外都一样的，所以有科学家认为蝙蝠是通过感觉气压来确定什么时候去捕食的。 SUPPORT。我的答案，下鱼天虫子少，但气压底，蝙蝠仍然出来捕食。

37. √412黑体句子作用题：A prominent investor who holds a large stake in the Burton Tool company has recently claimed that the company is mismanaged, citing as evidence the company’s failure to slow production in response to a recent rise in its inventory of finished products. It is doubtful whether an investor’s sniping at management can ever be anything other than counterproductive, but in this case it is clearly not justified. It is true that an increased inventory of finished products often indicates that production is outstripping demand, but in Burton’s case it indicates no such thing. Rather, the increase in inventory is entirely attributable to products that have already been assigned to orders received from customers.In the argument given, the two boldfaced portions play which of the following roles?A, the first states the position that the argument as a whole opposes; the second provides evidence to undermine the support for the position being opposed; B, the first states the position that the argument as a whole opposes; the second is evidence that has been used to support the position being opposed. C, the first states the position that the argument as a whole opposes; the second states the conclusion of the argument as a whole; D, The first is evidence that has been used to support a position that the argument as a whole opposes; the second provides information to undermine the force of that evidence; E, The first is evidence that has been used to support a position that the argument as a whole opposes; the second states the conclusion of the argument as a whole;

38. 450 Press secretary: Our critics claim that the President’s recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties. They offer as evidence the fact that 90% of the projects cancelled were in such districts. But all of the cancelled projects had been identified as wasteful in a report written by respected nonpartisan auditors. So the President’s choice was clearly motivated by sound budgetary policy, not partisan politics. Which of the following is an assumption on which the press secretary’s argument depends? A. Canceling highway projects was not the only way for the President to punish legislative districts controlled by opposition parties. B. The scheduled highway projects identified as wasteful in the report were not mostly projects in districts controlled by the President’s party. C. The number of projects cancelled was a significant proportion of all the highway projects that were to be undertaken by the government in the near future. D. (Omitted) E. Reports by nonpartisan auditors are not generally regarded by the opposition parties as a source of objective assessment of government projects.认为正确答案应为B.

42. 493 BF GWD 5-19 历史人口统计但选项和第二个划线部分变了（变成倒数第二句话了）
Historian: In the Drindian Empire, censuses were conducted annually to determine the population of each village. Village census records for the last half of the 1600’s are remarkably complete. This very completeness makes one point stand out; in five different years, villages overwhelmingly reported significant population declines. Tellingly, each of those five years immediately followed an increase in a certain Drindian tax. This tax, which was assessed on villages, was computed by the central government using the annual census figures. Obviously, whenever the tax went up, villages had an especially powerful economic incentive to minimize the number of people they recorded; and concealing the size of a village’s population from government census takers would have been easy. Therefore, it is reasonable to think that the reported declines did not happen. In the historian’s argument, the two portions in boldface play which of the following roles?
A  The first supplies a context for the historian’s argument; the second acknowledges a consideration that has been used to argue against the position the historian seeks to establish.
B The first presents evidence to support the position that the historian seeks to establish; the second acknowledges a consideration that has been used to argue against that position.
C  The first provides a context for certain evidence that supports the position that the historian seeks to establish; the second is that position.
D  The first is a position for which the historian argues; the second is an assumption that serves as the basis of that argument.
E  The first is an assumption that the historian explicitly makes in arguing for a certain position; the second acknowledges a consideration that calls that assumption into question.

43. 496 GWD-7-Q37 玉米减产，肉降价
Escalating上升 worldwide demand for corn has led to a sharp increase in the market price of corn, and corn prices are likely to remain high. Corn is extensive used as feed for livestock, and because profit margins are tight in the livestock business, many farmers are expected to leave the business. With fewer suppliers, meat prices will surely rise. Nonetheless, observers expect an immediate short-term decrease in meat prices.
Which of the following, if true, most helps to justify the observers’ expectation?
A  The increase in corn prices is due more to a decline in the supply of corn than to a growth in demand for it.
B  Generally, farmers who are squeezed out of the livestock business send their livestock to market much earlier than they otherwise would.
C  Some people who ate meat regularly in the past are converting to diets that include little or no meat.
D  As meat prices rise, the number of livestock producers is likely to rise again.
E  Livestock producers who stay in the business will start using feed other than corn more extensively than they did in the past.

Healthy lungs produce a natural antibiotic that protects them from infection by routinely killing harmful bacteria on airway surfaces. People with cystic fibrosis, however, are unable to fight off such bacteria, even though their lungs produce normal amounts of the antibiotic. The fluid on a0.irway surfaces in the lungs of people with cystic fibrosis has an abnormally high salt concentration; accordingly, scientists hypothesize that the high salt concentration is what makes the antibiotic ineffective.
Which of the following, if true, most strongly supports the scientists’ hypothesis?
A  When the salt concentration of the fluid on the airway surfaces of healthy people is raised artificially, the salt concentration soon returns to normal.
B  A sample of the antibiotic was capable of killing bacteria in an environment with an unusually low concentration of salt.
C  When lung tissue from people with cystic fibrosis is maintained in a solution with a normal salt concentration, the tissue can resist bacteria.
D  Many lung infections can be treated by applying synthetic antibiotics to the airway surfaces.
E  High salt concentrations have an antibiotic effect in many circumstances.

52. 592一道天山 Ecologist: The Scottish Highlands were once the site of extensive forests, but these forests have mostly disappeared and been replaced by peat泥煤 bogs沼泽. The common view is that the Highlands' deforestation was caused by human activity, especially agriculture. However, agriculture began in the Highlands less than 2,000 years ago. Peat bogs, which consist of compressed decayed vegetable matter, build up by only about one foot per 1,000 years and, throughout the Highlands, remains of trees in peat bogs are almost all at depths great than four feet. Since climate changes that occurred between 7,000 and 4,000 years ago favored the development of peat bogs rather than the survival of forests, the deforestation was more likely the result of natural processes than of human activity.
In the ecologist's argument the two portions in boldface play which of the following roles?
A The first is evidence that has been used in support of a position that the ecologist rejects; the second is a finding that the ecologist uses to counter that evidence.
B. The first is evidence that, in light of the evidence provided in the second, serves as grounds for the ecologist's rejection of a certain position.
C. The first is a position that the ecologist rejects; the second is evidence that has been used in support of that position.

【版本3】1102GWD-29-Q40 Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream. However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur. These results provide support for researchers’ prediction that naltrexone will turn out to be toxic to certain types of bacteria.
Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?
A After being administered to mice, naltrexone does not pass from the bloodstream into the intestine.
B Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
C Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance.
D The increased risk of blood poisoning is not the only harmful effect on mice of being given morphine.
E Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice.

version2 Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species. Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates. Clearly, dropping this restriction would allow the other species to recover.
Which of the following, if true, most seriously undermines the argument?
A Hunting limits for snow geese were imposed many years ago in response to a sharp decline in the population of snow geese.
B It has been many years since the restriction led to the hunting season for snow geese being closed earlier than the scheduled date.
C The number of snow geese taken by hunters each year has grown every year for several years.

77. √【版本1】972 天山-7-13
Lyme disease is caused by a bacterium transmitted to humans by deer ticks. Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected white-footed mice. However, certain other species on which the larvae feed do not harbor the bacterium. Therefore, if the population of these other species were increased, the number of ticks acquiring the bacterium and hence the number of people contracting Lyme disease would likely decline.
Which of the following, if true, most strengthens the argument?
A Ticks do not suffer any adverse consequences from carrying the bacterium that causes Lyme disease in humans.
B There are no known cases of a human’s contracting Lyme disease through contact with white-footed mice.
C A deer tick feeds only once while in the larval stage.
D A single host animal can be the source of bacterium for many tick larvae.

78. 973 GWD-5-Q30:
Which of the following most logically completes the argument?
The irradiation of food kills bacteria and thus retards spoilage. However, it also lowers the nutritional value of many foods. For example, irradiation destroys a significant percentage of whatever vitamin B1 a food may contain. Proponents of irradiation point out that irradiation is no worse in this respect than cooking. However, this fact is either beside the point, since much irradiated food is eaten raw, or else misleading, since _______.
A many of the proponents of irradiation are food distributors who gain from food’s having a longer shelf life
B it is clear that killing bacteria that may be present on food is not the only effect that irradiation has
C cooking is usually the final step in preparing food for consumption, whereas irradiation serves to ensure a longer shelf life for perishable foods
D certain kinds of cooking are, in fact, even more destructive of vitamin B1 than carefully controlled irradiation is
E for food that is both irradiated and cooked, the reduction of vitamin B1 associated with either process individually is compounded

79. 【版本1】977Many winemakers use cork stoppers软木塞; but cork stoppers can leak, crumble, or became moldy发霉, so that those winemakers must often discard a significant proportion of their inventory of bottled wine. Bottlemaster plastic stoppers, which cannot leak, crumble, or mold, have long been available to winemakers, at a price slightly higher than that of traditional cork stoppers. Cork prices, however are expected to rise dramatically in the near future. Clearly, therefore, winemakers who still use cork but wish to keep production costs from rising will be forced to reconsider plastic stoppers. And since the wine-buying public’s association of plastic stoppers with poor-quality wine is weakening, there is an excellent chance that the Bottlemaster plastic stopper will gain an increased share of the market for wine-bottle stoppers.

【版本2】1105附GWD-24-Q24
Many winemakers use cork stoppers; but cork stoppers can leak, crumble, or became moldy, so that those winemakers must often discard a significant proportion of their inventory of bottled wine. Bottlemaster plastic stoppers, which cannot leak, crumble, or mold, have long been available to winemakers, at a price slightly higher than that of traditional cork stoppers. Cork prices, however are expected to rise dramatically in the near future. Clearly, therefore, winemakers who still use cork but wish to keep production costs from rising will be forced to reconsider plastic stoppers. And since the wine-buying public’s association of plastic stoppers with poor-quality wine is weakening, there is an excellent chance that the Bottlemaster plastic stopper will gain an increased share of the market for wine-bottle stoppers.

Bottlemaster plastic stoppers, which cannot leak, crumble, or mold。（然后描述变了）现在的两者的价格差不多，但是不久cork要涨价。可是很多造酒者还是要用cork。说明价格不是他们考虑的唯一因素。我选的是两个都是evidence支持结论的。
