一题的正确答案是"To develop more accurate population forecasts, demographers would have to know a great deal more than they do now about the social and economic determinants of fertility.";另一题是"Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than in any previous election." 为什么前面这题"more than"后面有"they do",而后面这题"a greater proportion than"后面没有"it was"? 另外为什么前面这题要有个"would"? 请各位不吝赐教! |
