187. (GWD-1-Q32)

To develop more accuratepopulation forecasts, demographers have to know a great deal more than nowabout the social and economic determinants of fertility.

A.    have to know a great deal more than now about the social and economic

B.    have to know a great deal more than they do now about the social andeconomical

C.    would have to know a great deal more than they do now about the socialand economical

D.     would have to know agreat deal more than they do now about the social and economic   (D)

E.    would have to know a great deal more than now about the social andeconomic

这道是PREP08里的，答案是D。原因是比较两边要对等，是demographer现在know的和过去know的作比较，所以than后要补出they do。如果不补，会变成a great deal和now比较。

但现在问题来了！！

GWD1-Q16:

Soaringtelevision costs accounted for more than half the spending in the presidentialcampaign of 1992, a greater proportion than it was in any previouselection.

A.    a greater proportion than it was

B.    a greater proportion than

C.   a greater proportion than they have been

D.   which is greater than was so

E.   which is greater than it has been

这道题，答案是B，我选的A。我想请问各种NN，这道题B选项难道不会有a greater proportion和[size=12.499999046325684px] in any previous election 比较歧义吗？而补出it was用来指代spending is a greater proportion不是更清楚吗？

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 five years ago.

(A) making the construction industry’s economic health much more robust than five years ago

(B) and make the construction industry’s economic health much more robust than five years ago

(C) making the construction industry’s economic health much more robust than it was five years ago

(D) to make the construction industry’s economic health much more robust than five years ago

(E) in making the construction industry’s economic health much more robust than it as five years ago

比如这道题的正确答案是C，我理解是A中比较对象不对等。然后C中it was很清楚地指代了economic health was robust。。

所以问题就来了，第二道题中的为何不能选A呢?!!!翻了很多帖子，还是没有解决我心中的这个疑惑

亲，应该是it did 吧。。前面动词是accounted啊~~

同意这个。。。

187. (GWD-1-Q32) 这一题我觉得economical这个词用得不恰当，economical是经济的实惠的，或者经济学的，但社会经济的经济要用economic.

a greater proportion那个短语是修饰前句more than half这个比例，补出it指代谁呢？ ...

被你这么一问，我重新看了下题目，感觉more than half 本身自己就是一个修饰语，用来修饰spending的，我觉得这里a greater proportion是用来修饰 more than half the spending 整个短语比较合适啊！然后短语的重心是spending，而且你刚刚自己说，翻成中文是‘1992年的花费’和‘之前年度的花费’比较

而且 a greater proportion than +时间状语，真的不会有 proportion和时间状语的比较歧义吗？

因为根据第一题和第三题，名词+than+时间状语 这种结构是要严格避免的啊！

the construction industry’s economic health much more robust than it was five years ago改写成
the  ...

第一题比较的是主谓，补出 they do没有疑问。

但第三题这里，making the construction industry’s economic health much more robust than five years ago. 这整个是Ving状语表伴随结果的修饰成分啊，整个结构是：ving+宾语+宾补。。如果这样一个结构也需要加上it was来使句子更清晰，那为何B中不能加呢？

我的理解是，B中的 a greater proportion是个同位语修饰spending。
既然第一题和第三题是加了 代词+助动词 ，以此来避免造成 than后直接加时间状语的比较歧义，为何第二题就不加了呢？

我不觉得是两个时间状语的比较啊。你自己也说了，是1992年的竞选花费和之前的竞选花费之间的比较。那么比较的重点还是“花费”啊！

而且，就算是比较时间状语，我觉得应该写成...spending, a greater proportion in the presidential campaign of 1992 than in any previous election,这样不是更清楚明了么？
