问题描述：
Some countries in Africa have experienced__________this year as they did last year.
A.twice as much rain
B.rain twice as much
C.as twice much rain
D.twice rain as much
选什么,为什么?还有就是rain放在那个位置的原因.·
答
选A.
首先是词组as much as; 然后在much之后加rain; 再在as much rain as之前加倍数；这个词组就成为了twice as much rain as.
又如：I have twice as many books as you have.我的书是你的两倍.
