嘿..那最后你讨论的结果怎么样了?我隔了一天去找就怎么都没找到了..
根据白勇语法,两个句子并列,第一个句子BE动词或BECOME,第二个句子中的BE或BECOME必须省略.但是有多道题与此违背.
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
比如这题选B..没有问题...
但是以下是我的问题所在...:
1.Computers are becoming faster, more powerful, and more reliable, and so too are modems, they are the devices to allow two or more computers to share information over regular telephone lines.
(A) so too are modems, they are the devices to allow
(B) so too are modems, the devices that allow
(C) so too modems, the devices allowing
(D) also modems, they are the devices that allow
(E) also modems, which are the devices to allow
如C,若以此规律,C可以理解为省略啊?想请教各位为什么不可以呢?
2. Once the economic and social usefulness of the motor car was demonstrated and with its superiority to the horse being proved, much of the early hostility to it in rural regions disappeared.
(A) and with its superiority to the horse being
(B) and its superiority over the horse had been
(C) and its superiority to the horse
(D) its superiority over the horse
(E) with its superiority to the horse having been
此题C为什么也不能理解为省略WAS呢?而且一般不是A AND B ,A 在B 前发生吗..为什么B对呢..
还有一种省略.如
Founded in 1983, the magazine increased its circulation more than double since then, and its advertising.
(A) increased its circulation more than double since then,
(B) has since increased its circulation more than double,
(C) has since more than doubled its circulation
(D) since then more than doubled its circulation（C）
(E) more than doubled its circulation since then
这题选C没问题..关键是后一句省略把我弄糊涂了..完整是and the magzine increased its advertising.可是下题:
In 1973 mortgage payments represented twenty-one percent of an average thirty-year-old male’s income; and forty-four percent in 1984. (A) income; and forty-four percent in 1984 (B) income; in 1984 the figure was forty-four percent (C) income, and in 1984 forty-four percent (D) income, forty-four percent in 1984 was the figure（B） (E) income that rose to forty-four percent in 1984 这题的话,C为什么不可以也理解为省略了主谓呢?? 这些问题困扰我快半个月了..终于憋不住希望有同志可以帮帮我
(A) income; and forty-four percent in 1984
(B) income; in 1984 the figure was forty-four percent
(C) income, and in 1984 forty-four percent
(D) income, forty-four percent in 1984 was the figure（B）
(E) income that rose to forty-four percent in 1984
这题的话,C为什么不可以也理解为省略了主谓呢??
这些问题困扰我快半个月了..终于憋不住希望有同志可以帮帮我
拜托各位了..谁能给我说说吗....
d...啊啊啊..
第一题省略are的话，有歧义，我觉的so+助动词+N是固定搭配吧
第二题多数人倾向于答案是C，B不知道为什么使用完成时；不过有人说是superiority over /superior to 的搭配问题
第四题：的C选项OG解释是separate clause,因为不知道是forty-four percent指的是什么
所以你给的几题考点都不在助动词是否需要补出上
不过我也想请问LZ一下，第三题的C,D两个选项：
(C) has since more than doubled its circulation
(D) since then more than doubled its circulation
请问D错在哪？ 是没用完成时吗？
是的,这里since是副词的用法,但仍表示应用现在完成..
想问问你这些歧义在哪呢?如果有歧义的话为什么第一个题目可以省呢..仔细想想的确是个问题啊啊..我想了好多天了..
如果省去不会引起歧义的话自然择优选择，我觉的即使不省去最多也就算“effectiveness”，
如果一个选项省去但其他语法点有错，而另一个没有但其他没错，自然选后者。你上面的几个题我认为就是这样，说歧义也就第一题有歧义，大全里是这么解释的：
216, sec14-18
A) so too are modems, they are the devices两个句子少连词。
B) best.这里, and表明后面跟着是句子，不能省are。the 用特指that更好。
C) 少are会产生歧义：Computers are modems.
D) 两个句子少连词。
E) 歧义：Computers are modems.
第三题省略当然没问题..
the magazine increased A... and （
increased ）B发出动作的主体相同，谓语相同后一个自然可以省略
何况这个也不是这题的考点啊
第四题的C forty-four percent指代谁呢，什么比例呢？而B中的figure就很明确了，指的就是一个比重；C是缺少逻辑主语
mortgage payments represented twenty-one percent of an average thirty-year-old male’s income, and in 1984(mortgage payments represented) forty-four percent.这样理解对不对呢?
有点钻牛角尖..但是很想把这个问题弄清楚..以免以后再犯..实在谢谢你啊..
mortgage payments represented twenty-one percent of an average thirty-year-old male’s income, and in 1984(mortgage payments represented) forty-four percent.这样理解对不对呢?
不对，还是缺少主语..补全应该是
in 1984 the figure （mortgage payments represented an average thirty-year-old male’s income） was forty-four percent
这个我也困扰很久啊,上次你的并列问题我也始终没有找到答案,有时GMAT挺强盗的,,比如Founded in 1983, the magazine increased its circulation more than double since then, and its advertising.就有逗号了....
不对，还是缺少主语..补全应该是
in 1984 the figure （mortgage payments represented an average thirty-year-old male’s income） was forty-four percent
我再继续领悟...感谢感谢``一直给我耐心解答...
这个我也困扰很久啊,上次你的并列问题我也始终没有找到答案,有时GMAT挺强盗的,,比如Founded in 1983, the magazine increased its circulation more than double since then, and its advertising.就有逗号了....
这个不是正确选项啊。正确选项不是是 Founded in 1983, the magazine has since more than doubled its circulation and its advertising吗.
没有逗号意思清晰很完美的呢。
我总结了一点点,你的QQ是多少啊``我和你交流一下
