英语倍数的表达方法

例如：He earns five times as much money as I do，他赚的钱是我赚的钱的五倍。
（money是不可数名词，所以用much）She is twice as old as her brother，她的年龄是她弟弟的两倍。
（old后面没有名词，所以不加a/an）This box is three times as heavy as a normal one，这个盒子是普通盒子的三倍重。
（heavy后面有一个可数名词单数，所以加a）二、倍数+形容词或副词比较级+than这种方法也用于表示两个事物之间的倍数关系，但是更强调其中一个事物的特征。
例如：This car is three times faster than that one，这辆车比那辆车快三倍。
