1. 先说一下片段中出现的倍数表达法，其它的在下面再说，片段中说的是A拥有的东西是B的N倍，表达方式就是 A+has+倍数+as many(如果拥有的东西是不可数名词的话就用as much)+拥有的东西+as B，当中的A视为第三人称单数。

A has twice as many books as B.
A有的书本数是B的两倍。
A has twice as much cash as B.
A有的现金是B的两倍。

用英语表达"A 是 B 的 N 倍长（宽，高，大，重等）"，"A 比 B 长（宽，高，大，重等）N 倍" 或"A 的长度（宽度，高度，大小，重量等）是 B 的 N 倍"，可用下列几种句型。

1."A + be + 倍数 + as + 计量形容词原级 + as + B".
This tree is three times as tall as that one.
这棵树是那棵树的三倍高。
His father is twice as old as he.
他父亲的年纪有他两倍大。
2."A + be + 倍数 + 计量形容词比较级 + than + B "
The Yangtze River is almost twice longer than the Pearl River.
长江差不多比珠江长两倍。
The dictionary is exactly five times more expensive than that one.
这本字典比那本恰好贵5倍。
3."A + be + 倍数 + the + 计量名词 + of + B "
The newly broadened square id four times the size of the previous one.
新扩建的广场是未扩建时的四倍大。
4."The + 计量名词 + of + A + be + 倍数 + that + of + B "
