英语中倍数的问题
The steel output increased four times 钢产量增加了三倍.
The steel output was four times as great as that of last year.钢产量比去年增加了三倍.
为什么这两句话是这样翻译?four times 为什么译成三倍?
因为增加了3倍呀,那再加上原来的...所以3+1=4倍.
这个房间比那个房间大三倍:
This house is three times larger than that one.
(比较级 more than)
This house is three times the size of that one.
(名词 + of)
This house is three times as large as that one.
(as...as...结构)
记忆小窍门:所有表示倍数的句型都是先写出倍数,然后在后面跟上比较的内容.
要注意的是,英语中两倍通常不是用two times,而是用twice来表达
