英语中什么是什么的几倍有哪几种用法啊?

Answer 1

倍数的表达方式共：四种
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.
The production of grain has been increased by four times this year.今年粮食产量增加了4倍.
