1. The university's constitution defines the powers of
two governing bodies．The general council, which
currently retains authority over constitutional matters,
consists of all the university's living alumni．The
twenty-member senate decides routine matters by
majority vote．A new proposal suggests making a
unanimous vote in the senate sufficient to change the
constitution．
If the statements above are true, which of the fol-
lowing must follow on the basis of them？
(A) The proposal will take effect only if it receives
the senate's unanimous support．
(B) Currently each member of the senate has power
of veto over any proposal that comes before
that body．
(C) Adopting the proposal would allow passage of
constitutional changes without the general
council's approval．
(D) Any of the university's alumni can fill any one
of the twenty seats on the senate．
(E) Adopting the new proposal would increase the
voice of the alumni in the conduct of
university affairs．
答案C
5.In Diersville the new Environmental Action party
won two seats on the seven-member town council in
1988．It lost both of those seats in the 1992 election,
even though the party's pro-environment platform had
essentially remained unchanged．This decline in the
party's fortunes clearly demonstrates that in Diersville
environmental concerns faded in significance between
1988 and 1992．
Which of the following, if true, most seriously weakens
the argument？
(A) Between 1988 and 1992, the number of eligible
voters in Diersville rose, but not the percentage
who actually voted．
(B) Between 1988 and 1992, Diersville's leading
political party revised its platform, adopting
a strongly environmentalist stance．
(C) The parties that ran candidates in the 1992 elec-
tion in Diersville were the same as those that
had done so in the 1988 election．
(D) In 1992 the Environmental Action party won
fewer votes in Diersville than it had won in
1988．
(E) Between 1988 and 1992, some measures intended
to benefit the environment had been adopted
by the town council, but with inconclusive
results．
答案B

1. 第一层：两个立法组，C与S。 新规定（P）说，S全票通过就足以更改法律。（推论为：S→改法）
第二层： C 由alum组成，有立法权；S有立法权，但要多票通过。（矛盾不明显）
A. 关键词：P， only if ,S。             S与P的关系，无关选项，且反了。
B.........：member of S, P。          S与P的关系，无关选项。
C........：P, allow，否定C。           排他因强化：S足以改法。
D.........: alumni，S。                     第二层上，错位，无关。
E.........: P， alum。                      第一层与第二层混搭，无关。

5. 最后一句直接为推论： seat↓ 显示 environmental concerns↓
B选项的事实直接反对environmental concerns↓，属于直接削弱。
E选项有让步，削弱程度不及B
其他选项均无关，seat与concerns动作主体是leading  party，原文想说：是由于它对environment 不重视，所以降低了Action Party的表决权（少了俩坐）。而无关选项说的动作主体均为民众，且新对比往往在文中有差异对比相对应。
