Question

一道英语选择题，帮忙啊……

We produce_______we did two years ago.
A. double as much cotton as this year
B. twice as much cotton this year as
C. this year twice cotton as much as
D. twice as this year much cotton as
答案是B,请问为什么啊，解释的详细一点噢，谢谢！

Answer 1

这是表示倍数的一般结构
once as much/many as
twice as much/ many as
three times as much/many as
表示是……的几倍

cotton是不可数，所以用twice as much as
然后，名词一般放在much后面，就是twice as much cotton as……
最后就是再加上时间这类的状语，就变成 twice as much cotton this year as, 感觉上把很多成分都加在后面一个as 之前，倍数+as……+as……

Answer 2

本题考查英语倍数的表达方式。具体有以下几种表达方式：
A + 谓语+倍数+the +n.(size/ height/ length……)+of B
A + 谓语+倍数+as + abj. + as B
A + 谓语+倍数+adj. 比较级+than B
eg：This room is twice the size of that one.
 This room is twice as large as that one.
The Yangtze River is almost twice longer than the Pearl River.
本句句意：我们今年生产的棉花是两年前生产的2倍。

Answer 3

首先倍数一定是放前面的，两倍用twice,可以排除AC，this year为时间状语，放在后面，省去它不看，就是as much cottun as。。。

Answer 4

这道题考查的是倍数表达法以及as .....as的用法。一般碰到倍数，要把倍数放在前面。例如：This apple is twice as big as that.
as ...as的用法是：as +形容词或是副词的原级+as

在英语中表达倍数的时候通常不会用到double这种形式，所以A选项排除。C选项是背书放在后面了，所以也要排除。D选项是as后面要加形容词，所以也排除了。希望我的讲解能给你一些帮助。如果有问题，欢迎你继续提问。很愿意同你探讨英语学习上的问题

Answer 5

是今年与两年前比较，跟据as。。。as句型就应该是倍数加as加A加as加B的形式，因此选B
