题目:

To develop more accurate population forecasts, demographers have to know a great deal more than now about the social and economic determinants of fertility.

选项:

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

提问:

这道语法是OG12上的41题 我第一次做选D,觉得more than they do now,就是比较科学家们将要知道的和现在知道的,所以把AE扔了,然后感觉B的时态不太好,剩下CD,后面的economic更好,因此选了D 咱们系统上给的答案是E,听了老师的讲解,我还是不太明白more than they do now那块儿应该怎么判断.而且还是坚持之前自己的判断 后来做OG12发现这道题了,OG12认为E选项错误的原因是: wrong comparison---between what demographers need to know and now 请老师解答一下啊~~

提问:

ID649: 听了答疑录音很疑惑,有的老师说D有的老师说E。用more than 做比较的时候,到底是哪种表达更好?主语及动词省略更好(简洁行)?还是不省略更好?(准确清晰)

提问:

这道题我错选了B。有两个疑问:1.economical和economic的区别是什么? 2.感觉‘would’加不加都可以啊,为什么一定要有would呢,是为了表示将来时态吗?
