economical错误。 考点：logical predication, grammatical construction OG思路：首先明显是假设的情况，所以需要虚拟语气，同时很明显有比较，要保证的对象都是时间。 我的思路基本与OG一致。但虚拟语气考点不太熟

主语的比较，将来的主语与现在的主语比较，因此than后面要加新的主语，they do now

economical错了；more than后面省略了they would have to 逻辑错

应该是know a great deal 与 they do now比较，而不是 a great deal 与now 比较 且economical是节约的，错误

economical错,比较对象错误

economical错
JQueen 2015-03-06 11:55:15
比较对象错误，不是what demographers need to know 与 “now” （时间）的比较
