请列出题号. 便大家搜寻. thank you

go with D

1.economical的意思是节约,所以不对. B CE 错

2.最好用 would表示与现实相反.因为现在并没有"more accurate". 然后than后面,因为auxiliary verb的时态不一致,一个是would 一个是 do 所以不能省略,要补出do 来...所以A 错

D对!

不要靠would vs. will來選
看X than now的比較

我认为如果不是时态不一致a项的比较没错，than now可以这样省略的，大家觉得呢？

以下是引用china101在2009-6-25 17:57:00的发言：

A中没有they do应该不可以吧.

因为比较的是动作, 所以最少也要用do来代替,而不能省略.

OG 12
41. To develop more accurate population forecasts,
demographers have to know a great deal more than
now about 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 and economical
(C) would have to know a great deal more than they
do now about the social and economical
(D) would have to know a great deal more than they
do now about the social and economic
(E) would have to know a great deal more than now
about the social and economic

答案D

Verb form; Logical predication
Th is sentence explains a hypothetical situation
and therefore calls for a conditional—or contraryto-
fact—construction, because in order to more
accurately predict population, demographers
would have to know more than they presently
know. A present-tense verb is required to describe
the current state of demographers’ knowledge,
and the comparison made by the sentence must be
between current and conditional knowledge, not
between knowledge and time of knowing (now).
A Wrong comparison—between knowledge
and time (now); conditional verb is needed.
B Conditional verb is needed; economical is the
wrong adjective.
C Economical is the wrong adjective.
D Correct. Conditional knowledge, indicated
by would have to know, is correctly compared
to current knowledge.
E Wrong comparison—between what
demographers need to know and now.
Th e correct answer is D.

D 是正确的，E 错的

know more than now歧义，一定要补上主语和谓语

不然就好像说 ”you have to know more than now has to know".
Now变成比较后半部分的主语了。

楼上认为答案错咯？

作者: gtr 时间: 2010-2-5 00:00
ugh，你仔细把所有回帖都看一下吧

作者: agnesliu 时间: 2010-7-16 20:29
答案错误，D是对的。

OG12-41有原句，选的就是D。economic是经济上的，economical是节约的，实惠的
