以下是引用yiga在2006-2-2 12:37:00的发言：Q32:
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，我觉得用economical 不对吧，另外请问这里需要用would吗？
E (economical)是不对的.不是题写错了, 就是答案给错了.
AD中,D好些. D补的全点比A.
用不用would,从原文中看不出来. 也就是说,没有不能用would的理由.
