关于比较结构中状语的比较【求讨论】

MiaZhang

lz觉得，比较结构是GMAT SC的一个难点，LZ在做题时老是犯错。。。现在又要向大家求教了~~

看了很多题和解析后，我觉得，比较结构中状语的比较，大多数是把主语和位于省略的情况。
In no other historical sighting did Halley’s comet cause such a worldwide sensation as in its return of 1910-1911
不过省略主谓需要一个前提，就是，than后面的状语结构，必须在前文已经出现过，虽然形式上不一定相同，不过状语表达的含义一定是有可比性的，或者说是同类的
A large rise in the number of housing starts in the coming year should boost new construction dollars by several billion dollars, making the construction industry’s economic health much more robust than it was five years ago
下面这个句子，就是因为than前面没有出现相似的状语结构，必须把主谓补上
To develop more accurate population forecasts, demographers would have to know a great deal more than they do now about the social and economic determinants of fertility

lz对下面这个题还是有一点疑问的：
OG10- 198. Although Napoleon's armyentered Russia with far more supplies than they had in their previous campaigns, it had provisions for only twenty-four days.

(A)theyhadin their previous campaigns

(B)their previous campaigns had had

(C)theyhad for any previous campaign

(D)intheir previous campaigns

(E)for any previous campaign

Mia分析：这个题看起来像是状语的比较，但是than前面并没有出现过介词短语【for…】或者与【for...】含义相近的状语结构。试着补一下句子：

Although N’ army entered R with far more supplies 【for campaign】than 【it had had】for any previous campaign.

有哪位NN能解释一下，为什么会出现这种情况？？【for...】究竟是在和谁比较呢？

MM根据逻辑含义把句子补全就明白了，Although N’ army entered R with far more supplies (for this campain) than (supplies) for any previous campaign。。。。唉。。我也是受不了各种省，可是老美懒到家，能省就省。。。哭死。。。

就是这个问题啊~~既然前面吧for...都省略了，than后面怎么还能直接进行比较呢？
因为前面的题...would have to know a a great deal more than THEY DO NOW...
本来就是没有补出THEY DO，结果算错了。

回到这个题，for...前面也没有一个可以比较类似for结构的状语，怎么就对了呢？

sisichen666

我觉得是没有问题的，因为LZ给的例子...would have to know a a great deal more than THEY DO NOW...是由于前后比较的内容其时态发生变法，必须补出主谓结构。。。而且这道题省略并没有任何歧义啊，因为for的出现，很明确了是宾语+介词的比较，不会引起歧义比较，即使前面半部分是省略的。。。。。。

嗯，ls说的有道理~~
又看到一个句子：
There are no legal limits, as there are for cod and haddock, on the size of monkfish that can be caught, a circumstance that contributes to their depletion through overfishing.
这里应该也是一种比较，但是出现了和之前一样的“问题”。其实现在看来也不是问题了，是有一定道理的。
总结一下：
这两个句子里面的【for】都是【宾语+介词】中的介词结构，而且相同（虽然for后面的名词不同，但也算是同类），因此两个宾语可以共用一个介词短语而不会产生歧义。
这个时候，than两边的两个宾语可以共用一个介词短语结构（虽然介词后面名词可能不同），than后面可以省略宾语，也可以省略主语+宾语（如果时态没有发生改变的话），实质上还是宾语之间的比较。

MiaZhang

另外，有了上面的分析，我觉得这里的介词短语【for...】并不是做状语了，更像是作为定语修饰宾语中的名词，所以不应该跟状语的比较结构放在一起。上面两个句子的比较其实是宾语之间的比较。

这样区分是不是正确呢？感觉好像思路清晰了不少

其实我觉得没那么复杂


这道题几种比较其实都可以是对的 关键是后面的IT


前面就不能用THEY 或者THEIR吧？
