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

have to know a great deal more than now about the social and economic
have to know a great deal more than they do now about the social and economical
would have to know a great deal more than they do now about the social and economical
would have to know a great deal more than they do now about the social and economic
would have to know a great deal more than now about the social and economical

答案是E，为什么用economical 经济该用economic呀？

economical是用来修饰determinants的吧

我想问问为什么是WOULD呢..时态似乎不对

就是嘛，是不是A啊，疑惑中.....

economic = 經濟的

economical = 符合經濟效益的

eg. The economic performance of country X is not doing so well.

eg. The fuel consumption of this car is economical.

所以答案應該只有 A or D.

"would have" 的用法是用在一個已經改變不了的過去的事情

If I know that I will regret losing her, I would have tried my best to win her back.

所以很顯然這裡不是一個過去改變不了的事實

所以用 have 就可以了

選 A

have to 有很强的主观色彩...在GMAT中绝对不可以出现

大家的讨论好象没什么结果样

那是不是都觉得E不对？ECONOMICAL是错的

而且前面是SOCIAL，后面肯定应该是经济上的而不是经济节约的
