请教大全118,119,139三题

118. Art museums do not usually think of their collections as capital or consider the interest income that would be generated if a portion of the capital would have been invested in another form.
(A) be generated if a portion of the capital would have been
(B) have been generated if a portion of the capital would have been
(C) be generated if a portion of the capital were
(D) be generated if a portion of the capital was
(E) be generated if a portion of the capital had been

答案是C，我选的是D，为什么是were呢a portion of the capital应该不可数吧，难道是类似与“If I were you”的用法？

119. Artificial intelligence emerged during the late 1950’s as an academic discipline based on the assumption that computers are able to be programmed to think like people.
(A) are able to be programmed to think like people
(B) were able to be programmed to think as people
(C) can be programmed to think as people can
(D) could be programmed to think like people
(E) are capable of being programmed to think like people do

答案是D，由于时态问题，可以先排除AE，剩余的BCD中为什么要选D呢？think as people和think like people有什么区别呢

139. As the etched lines on computer memory chips have become thinner and the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have vastly increased.
(A) the chips’ circuits more complex, both the power of the chips and the electronic devices they drive have
(B) the chips’ circuits more complex, the power of both the chips and the electronic devices they drive has
(C) the chips’ circuits are more complex, both the power of the chips and the electronic devices they drive has
(D) their circuits are more complex, the power of both the chips and the electronic devices they drive have
(E) their circuits more complex, both the power of the chips and the electronic devices they drive have

答案选B，我选了A，到底both the power of和the power of both有什么区别啊，为什么选后者，难道前者应该也用has？

期待解答！！

118 单数或复数的谓语动词取决于capital 是不是可数名词；可数名词

119 as 作像讲，是连词，而连词后面要跟句子；

139 A 中both the power of the chips and (the power of)electronic devices，有歧义

第一题我不清楚

第二题我觉得是:

can/could 强调可能性

able/ablility什么的强调能力

所以你不明白的BCD选项中应先排除B

然后是as和like:  as后面应该是句子,比如as people do

                          like的话可以跟名词,比如like people

第三题

你不明白both the power of和the power of both的区别,我觉得是这样的

如果是the power of both A  and B 的话,那么这部分句子的主语是the power,所以后面的谓语动词应该是单数

但是如果是both A and B的话, 那么这部分句子的主语就是复数, 所以后面的谓语动词应该是复数

所以, both the power of和the power of both问题是不存在的,考点是主谓一致,看主语是什么,后面跟什么

我自圆其说的

个人觉得118时虚拟语气来的

个人认为Gudjohnson对第118题的理解错了，这题考的是虚拟语气，所以用were.
