Medical personnel who served in heavy combat in a
recent war-even those who escaped physical injury-now
have lower incomes and higher divorce rates, and score
lower on psychological profiles measuring general
happiness, than medical personnel who served in less
stressful settings during that war. This evidence
demonstrates that exposure to heavy-combat situations
produces serious adverse effects, even among those who
suffered no physical harm.
Which of the following, if true, most strengthens the
conclusion drawn above?
The medical personnel who served in heavy combat had
completed significantly less schooling prior to military
service than had other medical personnel.
The medical personnel who served in heavy combat
tended to be younger at the time of their entry into
military service than were other medical personnel.
Parents of medical personnel who served in heavy
combat show no significant difference in incomes,divorce
rates,or general happiness from parents of other medical
personnel.
Income levels, divorce rates, and levels of general
happiness are the same for the medical personnel who
served in heavy combat as they are for construction
workers.
Medical personnel who served in heavy combat in an
earlier war show no significant difference in incomes,
divorce rates, or general happiness from other medical
personnel who served in that war.

答案：(C)
问题：下面哪一个，if true，最支持上面的结论？
读题：服务于重大战役的医疗人员 —— 甚至那些没有受伤的医疗人员比那些不那么有
压力的医疗人员,现在有较低的收入，较高的离婚率，并且在测量一般快乐的心理
侧面图得分低。这个证据表明对重大战争情况的暴露产生了严重的不利影响，
甚至是对那些没有受到物理伤害的人。
分析：论据是一个事实，服务于重大战役的医疗人员比不那么有压力的医疗人员有较低
收入、离婚率高等情况。
结论是对重大战争情况的暴露产生了严重的不利影响(这也是原文中比较涉及的唯
一区别点) 结论对事实做了一种解释。
此类支持形式为：
1、 没有其他的原因来说明为什么服务于重大战役的医疗人员比不那么有压力的医疗人员
有较差的状况。
2、 直接说那些较差的状况和对重大战争情况暴露两者之间的关系
c. 服务于重大战役的医疗人员的父母与其他医疗人员的父母在收入、离婚率和快乐方面是
没有显著区别的
（利用了assumption的形式，遗传不起作用，最好地支持确实是环境起了作用）
e. 在上一次战争中，服务于重大战役的医疗人员与其他医疗人员没有显著不同
（上一次没有这样的情况，可以作为反对，注意答案不需要充分性）
No one can be licensed as an electrician in Parker
County without first completing a certain course in
electrical safety procedures. All students majoring in
computer technology at Parker County Technical College
must complete that course before graduating. Therefore,
any of the college's gr
共7页: 1 [2] [3] [4] [5] [6] [7] 下一页
aduates in computer technology
can be licensed as an electrician in Parker County.
The reasoning in the argument above is open to
question because the argument has not established
that
everyone who has completed the course in electrical
safety procedures is equally knowledgeable about such
procedures
all students majoring in computer technology who
complete the course in electrical safety procedures at
Parker County Technical College eventually graduate
completion of a course in electrical safety procedures
is all that is necessary for a person to be licensed as
an electrician in Parker County
the only way for a person to become knowledgeable
about electrical safety procedures is to take a course
in those procedures
the only students at Parker County Technical College
who are eligible to take the course in electrical safety
procedures are majoring in computer technology

答案：(C)
问题：上述推理有问题，因为论述没有建立——
（这种问法其实也就是论述所基于的假设）
读题：1、在Parker县只有先完成电子安全程序方面的某门课程才可能获得电工证书。
2、Parker 县技术学院计算机技术专业的所有学生毕业前都必须完成这门课，
所以，该院毕业于计算机技术专业的任何一个学生都能够获得电工证书。
分析：第一句话，获得电工证书→完成课程
第二句话，毕业学生 → 完成课程
而最后一句话得到结论为：毕业学生→获得电工证书
很显然，结论要成立的话，必须有完成课程 → 获得电工证书成立
B. 计算机专业所有完成课程的学生最后都毕业了
C. 完成电子安全程序方面的某门课是学生获得Parker县证书的所有的必要条件
（完成电子安全程序方面的某门课程是所有必要条件的话，
那么 完成课程 → 获得电工证书 能够成立）
D. 一个人在电子安全程序方面变得有学问的唯一方法是在那些程序方面选择一门课
E. Parker技术学院有资格选修电子安全程序方面课程的学生仅限于计算机技术专业。
At a film festival, six films--P, Q, R, S, V. and X-- are being presented

Each of seven authors--H, J, M, P, Q, S, and T--is featured as a subject
for discussion in at least one of exactly four consecutive lectures. The
following conditions govern the assignment of the authors to the lectures
in which they are featured:
Each lecture must feature exactly two of the authors, and no
author can be featured in any two consecutive lectures.
J and P cannot be featured in the same lecture as each other.
If either H or S is featured in a lecture, both H and S must be
featured in that lecture.
A lecture cannot feature S unless it is immediately followed
by a lecture featuring T.
A lecture cannot feature T unless it is immediately followed
by a lecture featuring J.
Which of the following is an acceptable assignment
of authors to the lectures in which they are featured,
in order from the first lecture to the fourth lecture?

答案：(B)
读题：7个作者H、J、M、P、Q、S、T，每人至少在4个连续的演讲中参加一场讨论。
写条件：
1、Each 2,～Con （表示每个演讲有exactly2个作者，没有人在连续的2个演讲）
2、J≠P （表示J和P不在同一个演讲中）
3、H=S （表示H、S必须在同一个演讲中）
4、S→ST （表示一个演讲中有S，则在紧随其后的演讲中有T）
5、T→TJ （表示一个演讲中有T，则在紧随其后的演讲中有J）
条件总结：
*1、读题时注意到，第一行的第一个词是Each，表示每个人都必须参加。
一个4个lecture,而条件1有Each lecture 2个人，则2×4=8 个人。
所以7个人中有1人参加2个lecture，其余6人只参加1个lecture，当然从这里还可
以进一步结合条件3，H=S得，H,S只参加1个lecture
*2、由条件4、5得，STJ连续
再加上条件3得，
H
S T J
*3、一共4个位置，则马上把题目可以分为2种情况
到此为止，下面6个小题已不费吹灰之力。
其实第一步是我们通常的数字总结。
第二步是具有相同元素的条件之间的总结。
第三步是考虑到位置个数和连续之间的关系。
If H is Featured in the first lecture, which of the
following must be featured in the third lecture?
H
