倍数表达，借花献佛

倍数表达

1. times (twice) +the + n.

2. x times adj. (比较形式) than(manhattan说这种表达不够clear)

3. x times as adj.as    

4. x times +what 分句  

5. x-fold

6.double, triple,quadruple, quintuple,

这样的题目, 首先要弄清楚比较的双方是否合理, 如果合理的话, 再看twice作为副词的位置: 可以用在as..as或比较级之前, 也可以放在比较点的名词之前, 担要保证twice前后的词要能直接搭配(副词的作用).

(B)    increased more thantwo times
(C)    more than doubled

A中是twice as fast as the 1970’s 在这里是rate和1970's比较，是不对的
B 意思是A的人口增长率是B的（人口增长率）的两倍一样快, rate 不能够fast, increase 才能够fast
C选项的意思是：A的人口增长率是B的两倍

待确认中。。。。

是有什么疑问吗？

wangjieava23

恩，就是说资料有可能不正确。不知道大家什么看法。但是毕竟是GMAC出题，我想应该用它的材料。要是别人的材料，可能也可以讲得通。但是，毕竟体系不一样，就有可能造成混乱。
我昨天，看一下午楼主的总结。看到这两个题，就没有思路了。
