两倍是double三倍是triple，那四倍五倍六倍七倍八倍九倍十倍都怎么说？

**小白老师说：**今天给大家介绍从"两倍"到"十倍"的英文表达，纯属扫盲大家可以从下列词中找出规律。

两倍 double

三倍 treble/ triple

四倍 quadruple

五倍 quintuple

六倍 sextuple

七倍 septuple

八倍 octuple

九倍 nonuple

十倍 decuple

也许有同学要问了：“一倍” 怎么说? 如果说A的数量是B的一倍，那不就是A=B吗? 即：A equals B。如果说A比B多一倍，也就等于A的数量是B的两倍，就要用double一词了。所以英文里一般不说…as one time as…。但是有half as much again的说法，意为"一倍半"。

我们一起来看一些例句。

1. Three of my veins had furred up and I needed a triple bypass.
