英语倍数的几种表示方法

Answer 1

英语中,倍数的表达有许多细微的区别.这里只介绍倍数的一般表达方法.
1. 表示“几倍大小（长短；数量）”,由“倍数+ the size（length,amount……）”结构组成.
例如：The earth is forth-nine times the size of the moon. 地球是月亮的49倍大.
2. 表示“……比……大几倍”,由“倍数+形容词（副词）比较级”结构组成.
例如：This box is three times bigger than that one. 这个盒子比那个盒子大三倍.
The grain output is 8 percent higher this year than that of last year.
今年比去年粮食产量增加8%.
3. 表示“……是……倍”,由“倍数+ as +形容词+ as +”结构组成.
例如：Our factory is twice as big as theirs. 我们的工厂是他们的三倍.
I have three times as many as you. 我有你三倍那么多.
[注] 一倍用once,两倍用 twice.
4、还可以用by+倍数,表示增加多少倍.
