How often,how long和how soon我们可称他们为三兄弟。他们都含有“多长,多久”之意。但是他们都各自为政、各占各座。
先来说说how often,这是询问情况发生的频率程度。译为“多久一次”,如:
—How often do you go to the theatre?
—A month.
—你多长时间去一次剧院?
—一月一次。
接着再说how long.它是指某种延续性的状况或行为持续多长时间。译为“多长时间”或“多久”,如:
—How long did you stay there?
—Three weeks.
—你在那儿呆了多久?
—三周。
最后说说how soon,它是指说话后的一段时间将发生的事情,用于表示将来的动作或状态,回答时常用介词“in +短语”,译为“在……之后”,如:
—How soon will her sister be back?
—I think shell be back in four days.
—她姐姐什么时候回来?
—我想她四天后能回来。
