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, 但有两点不解 1)应该用economic 还是economical?我觉得这里似乎应用econimic:经济的,而economical 指的是节约的;2)应用more than now 还是more than they do now? 请斑竹及各位NN指点迷津 万分感谢!其实这个题以前有个兄弟问过不过没人答复 ![](/static/legacy-emoticon/Dvbbs/em04.gif) |
