The two digits must be next to each other, and the two letters must be nex
t
to each other.
Of the two digits, the one to the left must be less than the one to the ri
ght.
The two letters must be different letters.
Which of the following could be the third symbol in a code in which the four
th
symbol is 3?
W
X

答案:(A)
Bats emit sounds and generally use the echoes of these sounds highly
efficiently to detect, locate, and catch their prey. However, it is claimed
that the characteristic efficiency of this process is reduced by moths able
to
hear the sounds emitted by insect-eating bats.
Which of the following statements, if true, best supports the claim above?
Those moths that cannot hear the sounds emitted by insect-eating bats live
longer on the average than those that can hear such sounds when both kinds
of
moth are in an environment continuously free of such bats.
Those moth species that cannot hear the sounds emitted by insect-eating bat
s
are among the species of insects that are most likely to be caught by such
bats.
When a moth changes its speed or direction of flight, there is a change in
the sound pattern generated by the moth's wing movements.
Moth species that can hear the sounds emitted by insect-eating bats are les
s
likely to be caught by such bats than are moth species that cannot hear th
ese sounds.
Moths that are capable of hearing the sounds emitted by insect-eating bats
differ in their abilities to use evasive action to escape capture by such
bats.

答案:(D)
问题:下面哪一个陈述,if true,最支持上面的论述?
读题:蝙蝠发出声音并利用声音的回声来高效地探测、定位和捕获被捕食者。 然而据宣
称:这个过程的特有效率被能够听到声音(蝙蝠发出的)的飞蛾降低了。
分析:上面的宣称显然就是由it is claimed引导,对这种题目中不存在因果关系的cla
im,
只要进行直接支持,找一个选项达到这种效果,听到声音的蝙蝠的确不容易被抓住。
A. 在没有吃昆虫的蝙蝠环境中,不能够听到蝙蝠发出声音的飞蛾活得长比能够听到声音
的飞蛾活的长(原文讨论的是有蝙蝠的环境下)
B. 不能够听到声音的飞蛾是昆虫种类中最可能被蝙蝠捕获的
(不能够听到声音的飞蛾最可能被蝙蝠捕获,但是能够听到声音的飞蛾到底怎么样,你
是不知道的)
C. 当一只飞蛾改变其飞行速度和方向时,其翅膀运动产生的声音模式也改变
D. 能够听到声音的飞蛾比不能够听到声音的飞蛾更有可能不被捕获
(用了一个比较,直接说这种效率被降低了)
E. 能够听到声音的蛾子在逃避被蝙蝠捕获的能力上不同。
Mass transit authorities in large cities are struggling with deficits. Rider
s complain
about delays and breakdowns, cuts in service, and fares higher than they are
accustomed to paying. For all these reasons and because the price of gasolin
e
is still not prohibitive, the number of passengers using public transportati
on has
fallen, adding to the deficits.
Which of the following statements about the relationship between the number
of
riders using public transportation and the price of gasoline is best support
ed
by the passage above?
As the price of gasoline rises, the number of riders using public
transportation rises.
Even if the price of gasoline rises, the number of riders using public
transportation will continue to decline.
If the price of gasoline rises to a prohibitive level, the number of riders
using public transportation will rise.
The majority of riders using public transportation do not use gasoline; hen
ce,
fluctuations in gasoline prices are unlikely to affect the number of rider
s using
public transportation.
The price of gasoline is always low enough to make private transportation
cheaper than public transportation; hence, fluctuations in gasoline prices
are
unlikely to affect the number of riders using public transportation.

答案:(C)
问题:下面哪一个关于使用公共交通乘客的数目和汽油价格的关系最容易被上文支持?
(显然读题时需要注意the price of gasoline and the number of passengers)
读题:大城市中的公共运输机构正在与赤字作斗争。乘客抱怨交通延迟和瘫痪,服务减
少、费用增加。所有的这些原因以及因为汽油的价格仍然不是高的吓人,导致公共交通
的乘客下降,增加了赤字。
分析:第四行For all these reasons and because引导原因:所有的这些原因以及因
为汽油的价格仍然不是高的吓人
紧接着后面就是结论:导致公共交通的乘客下降
这也就是汽油价格和公共交通乘客数目之间的关系。注意问题是从上到下,因此题目中
的论述都是在已经成立的情况下作出的。上面的因果关系也已经成立,公共交通乘客下
降的原因就是汽油价格不是高的吓人以及上面的其他原因。
A. 汽油价格上升,乘客数目增加
(注意原文中是汽油价格不是高的吓人,是一个状态量,而价格上升,涉及的是一个过
程量,因此无法被上文支持。)
B. 即使汽油价格上升,乘客数目仍然下降
(和A一样的错误)
C. 如果汽油价格上升到贵的惊人的地步,乘客数目增加
(逆否命题就是乘客数目下降得到汽油价格不是贵的惊人,与上面论述中的因果关系刚
好相同)
D. 大多数使用公共交通的乘客不使用汽油,因此,汽油价格的浮动不可能影响使用公共
交
通乘客的数目
E.汽油的价格足够低,使得私人运输比公共运输便宜;因此,汽油价格的浮动不可能影
响使用公共交通乘客的数目
The popular notion that teachers are generally apathetic about microcomputer
technology is false, or at least dated: a recently published survey indicate
s
that 86 percent of the 5,000 teachers who responded to survey questionnaires
expressed a high level of interest in microcomputers.
Which of the following, if true, would be most damaging to the argument abov
e?
No attempt was made in the survey to determine whether the teachers who
received questionnaires had any previous experience with microcomputers.
Teachers who are interested in microcomputer technology were more likely
than others to complete and return their questionnaires.
Questionnaires were sent to teachers without regard to their areas of subje
ct-
matter expertise or teaching experience.
There have been several important developments in the classroom application
s
of microcomputer technology since the survey results were tabulated.
The survey was conducted as part of a marketing study by a company that
manufactures and sells microcomputers.

答案:(B)
问题:下面哪一个,if true,最反对上面的论述?
读题:认为教师通常对微电脑技术缺乏兴趣的想法是错误的,或者至少是过时的:最近
公布的调查表明,5000名对调查表作出反映的教师中,86%表达了对微电子技术的
高度兴趣。
分析:第一句话是结论:教师通常对微电脑技术缺乏兴趣的想法是错误的
论据是一个调查:5000名有反映的教师中,86%表达了高度兴趣。
从论据5000名老师得出结论中的generally的老师,显然是从局部数据得到一个结果,
要想成立必须基于一个假设,这5000名老师是有代表性的,而让我们反对的话,只要指
出他们的特殊性就可以了。
A. 调查中没有做出任何努力来决定接受问卷的老师以前是否有微电脑技术的经历
(表明他们没有特殊性,因此为SUPPORT)
B. 对微电脑技术感兴趣的老师比其它人更有可能完成并交回问卷
(表明这5000名老师是有特殊性的)
C. 问卷散发给老师时,没有考虑他们所从事的专门技术领域和教学经历
(说明这5000名老师不特殊,可以作为SUPPORT)
D. 自从调查结果被制成表格以后,在微电脑技术的教室应用中有几个重要的发展
E. 调查是由一家生产和销售微电脑的公司作为市场调查的一部分来进行的

如果LO≠1,下面那一个一定正确?
1. 由条件2得,LO一定在第二轮,但是找答案并没有发现。
2. 由于是must be true,继续推导,那么该使用什么条件呢?此时还仅剩下一个条
件1可用,不能连续玩3轮,那么意味着在234这连续3轮之中,L,O只能玩2轮

在一次游戏中,如果J,L,M=1,K,M,O=2, 下面哪一个必然在第四轮?
原文中还剩下两个条件,那一个条件限制那一轮必然有谁呢? 显然是第二个条件,
没有人能够连续两轮不玩(在某一轮不玩,那么在下面一轮一定玩)。所以问谁不
在
第四轮,那么就只要考虑谁在第3轮或者第5轮不玩。而题目已知告诉了第1和第
2轮,我们当然考虑谁不在第3轮。
那么哪一个条件限制某一轮没有谁呢?显然是第一个条件,在连续玩了两轮之后,
接下来的那轮它就不能玩了。我们看一下那个元素在第1,2轮都玩了呢?显然是
元
素M, 所以M不在第3轮, M一定在第四轮。
16,17题都使用这种逆向思维

如果K演1, 下面那一个一定正确?
K演1,而K是男演员,男演员演的角色为123,因此剩下角色23要由K,J来演。
由于23必然会同台,不能够由一个人来演,因此23必然是K,J一人演一个。
K还必须从23里面挑出一个,但是到底是那一个呢?K演1,那么必然找一个与1不在
舞台上同时出现的角色,而角色1,3必然同台,12不需要同台,因此只能K演2。所
以,角色123的分配为,K演12,J演3。此时看答案,但是选项中没有,那么接着
推导。
推导方向是什么呢?K演12,已经没有条件与此相关。J演3,与此相关的有3,6和
3,7不需要同台,能由一个人演,但是6由T演,3,6不需要考虑,考虑3,7。角
色7既可由男演员,也可由女演员来演,女演员R和S只演458,不能演7,而角色6
和7必须同台,因此T也不能够演7,那么7只能够由男演员来演,而7只可以与3不需
要同台,与演角色12的演员需要同台,因此K不演7,那么只能是演3的演员演7。由
此,整个角色分配为:
12一个人演
37一个人演

因此R和S只能够演3对角色,4-5,4-8,5-8,也就是说,R和S只能再458三个角
色中演,而角色4,5,6必须由女演员R,S,T来演,因此,角色6只能由T来演。
Which of the following actors CANNOT play more than one role, regardless of
the other role assignments?
Jeff
Kirk
Rena
Sara
Tanya

答案:(E)
读题:一个剧团演唱组包括两个男演员,J、K;3个女演员,R、S、T, 计划演8个角
色,角色123由男演员演,角色456由女演员演,角色7、8可男可女。每个演
员至少演一个角色,角色的数目使得一些演员必须演多个角色。(下面的角色对
是
仅有对,不需要演角色的演员同台的仅有对),(这些角色的出现被分隔的足够开,
使得他们有时间化妆演多于一个角色。)
1-2, 3-6, 3-7, 4-5, 4-8, 5-8
R和S不能演要求他们同台的角色对。
题目分析:
*题目中有一个字not下面加了下划线,并且我们已经说过,读题时必须注意一些限制
性的词语,not前面的only是我们需要注意的,它指出,下面六对角色是不需要同台的
仅有对,也就是说,其他的角色对都需要同台,比如说角色1和角色3,是必然会同台。
* (这些角色的出现被分隔的足够开,使得他们有时间化妆演多于一个角色。)这句话
告
诉我们只有这上面六对角色可能由一个人来演,其他的角色对不能够由一个人来演。
* 最后一句话:R和S不能演要求他们同台的角色对。联系前面的条件,下面六对角色
是不同台的仅有对,这意味着R和S只能够演上面六对角色。再找R和S的条件,R和
S都是女演员,而角色123只能够由男演员来演,
因此R和S只能够演3对角色,4-5,4-8,5-8,也就是说,R和S只能再458三个角
色中演,而角色4,5,6必须由女演员R,S,T来演,因此,角色6只能由T来演。
In March 300 college students turned out in Washington to protest against
proposed cuts in student loan funds. Another 350,000 collegians flocked to
Florida's sun-drenched beaches during March for "spring break." Since the
Florida sun-seekers were more numerous, they were more representative of
today's students than those who protested in Washington, and therefore
Congress need not heed the appeals of the protesting students.
The argument above makes which of the following assumptions?
The students who vacationed in Florida did not oppose the cutting of studen
t
loan funds by Congress.
The students who vacationed in Florida were not in agreement with the opini
on
of the majority of United States citizens about the proposed cut in loan f
unds.
The students who protested in Washington were more seriously concerned abou
t
their education than were the students who vacationed in Florida.
The students who neither protested in Washington in March nor vacationed in
Florida in March are indifferent to governmental policies on education.
The best way influence congressional opinion about a political issue is to
communicate with one's elected representative in Washington.

答案:(A)
问题:上面的论述作了下面哪一个假设?
读题:三月,300名大学生出现在华盛顿抗议削减学生贷款基金。另外35万学生飞到
Florida的阳光海滩进行春季休假。 因为Florida寻求阳光者的人数更多,他们与
在华盛顿进行抗议的学生相比,更是当今学生的代表。因此,议会不需要注意抗
议
学生的要求。
分析:第5行Since引导原因,因为休假的人多,抗议的人少,人多更是代表,
得到结论不需要注意抗议。原因和结论之间显然存在一定差距。
A. 在Florida度假的学生不反对议会提出的削减学生贷款基金
(说出了休假学生与抗议之间的关系)
B. 在Florida度假的学生在关于削减学生贷款基金的问题上与大多数美国公民的意见不
一致
C.在华盛顿进行抗议的学生比在Florida度假的学生更关心他们的教育
D.既不在华盛顿进行抗议的学生也不在Florida度假的学生对政府关于教育的政策莫不
关心
E.影响议会关于一个政治问题意见的最好方法是与在华盛顿的代表通话、联系
Some doomsayers are warning that long-range warming or cooling trends in
weather patterns will drastically reduce grain production. More optimistic
reports, however, point out that, even if such drifts in average temperature
do
occur, we should expect little change in grain production because there is
little evidence that changes in rainfall patters will occur. Moreover, for
must crops, climate-induced yield trends will be masked by both the year-
to-year fluctuation of yields and by the enhancement of yields because of
technological factors.
Which of the following is an assumption on which the more optimistic reports
mentioned in the passage are based?
Long-range changes in weather patterns cannot be accurately predicted.
The growing of grain is so highly dependent on technological factors that
improvements in yield are unlikely, regardless of climatic conditions.
Trends in rainfall patterns are more difficult to isolate than are trends
in temperature.
Long-range warming or cooling trends are more damaging to grain production
if they are accompanied by changes in rainfall patterns than if they are n
ot.
Long-range cooling trends are potentially more destructive to grain product
ion
than are long-range warming trends.

问题:下面哪一个是更乐观的报道所基于的假设?
(读题时当然要注意文中更乐观的报道是什么?其他的信息都不用管)
读题:一些凶事预示者警告说:天气模式长期变暖或变冷的趋势将强烈地减少谷物产量
。
然而,更多乐观的报道指出:即使在平均温度上这种漂移真的发生,谷物产量也会有很
小的变化,因为几乎没有证据表明降雨模式将发生改变。此外,对大多数作物来讲,由
