GWD1-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
BCE可以淘汰。社會的跟經濟的正確用法應該是social and economic …. 但是我比較有疑惑的是在面對A跟D兩個答案時,在語態上為什麼不是選A而是選D? have to 跟 would have to 語氣上,後者有"應該必須..."的意思,可是,A的選項在文法判斷上並沒有明顯的問題呀? 煩請各位賜教.謝謝~~![dvubb 图片点击可在新窗口打开查看](http://forum.chasedream.com/Skins/Default/emot/em31.gif) ![dvubb 图片点击可在新窗口打开查看](http://forum.chasedream.com/Skins/Default/emot/em31.gif)
