今天做了一套GWD 对其中一道语法题的答案有疑意, 特此跟大家讨论一下. 题目如下: 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 economical 我选A, 答案给的是E. 首先,我没发现A 有什么不对; 其次,从词的意思上说,应该是 economic determinants, economical 是节俭的意思,应该排除B, C, E.最后,也没有什么特别的理由,把have to 改成would have to, 也就是D答案. 实在不明白,请赐教!! 谢谢!! |
