a是b的几倍用英语怎么说?
一倍的英语单词是once,两倍的英语单词是twice和double。三倍的英语单词是three times,N倍的英语单词是N times。
A是B的N倍,表示A是B的N倍(即A比B大N-1倍)时,有以下三种基本表达:
1、A is N times as large/long (形容词/副词原形) as B.
例:Asia is four times as large as Europe.
亚洲是欧洲的四倍大。
2、A is N times larger/longer(形容词/副词比较级)than B.
例:Asia is four times larger than Europe.
亚洲是欧洲的四倍大。
尽管字面上来看是亚洲比欧洲大四倍,但是使用times的时候,实际上表示的是单纯倍增的关系,故而,理解为”亚洲是欧洲的四倍大。"
3、A is N times the size/length (形容词/副词的名词形式) of B.
例:Asia is four times the size of Europe.
亚洲是欧洲大小的四倍。
扩展资料:
不管是n times larger 还是n times as large as,是多少times就是几倍。
但如果你说A is 100% larger than B(A比B大100%),这就等于说A=2×B(A是B 的两倍)。
所以,
如果A is 300% larger than B,那么就等于说,A=4×B;
如果A is 3 times larger than B,那么就等于说,A=3×B。
例:Asia is 300% larger than Europe.
亚洲比欧洲大3倍。
