请问twice as many A as B 何解

求教，：…twice as many A as B。

我一直以为是A是B的2倍。但是昨天2个筒子给我说是B是A的2倍。。。。求教各位到底是如何理解

你是对的，A是B的2杯。 有查到的例句~~                                                                       We've produced twice as much cotton this year as （ we did ） ten years ago.

今年我们生产的棉花比十年前多了一倍。（汉语中的多一倍实际上也指两倍一样多。）

He has got three times as many books as his sister.

他拥有的书的数量是他妹妹的 3 倍。

Of the 60 animals
on a certain farm, 2/3 are either pigs or
cows.  How many of the animals are cows?

 (1)  The farm has more than twice as many cows as
it has pigs.

 (2)  The farm has more than 12 pigs.

答案是C

由此看出,题目中表示的是2pigs=cows
