来个英语语法高手~It has been _____a year since we last heard from him.
It has been _____a year since we last heard from him.
A.for B.within C.after D.over
这是高中语法书上的历年真题翻译为自从最后一次收到他的信已经一年多了.
问：为什么A不可以?for+一段时间不是典型的现在完成时的时间状语吗?翻译为自从最后一次收到他的信已经有一年了.

解答

你说的没错for是可以加一段时间,比如He has been taken to the hospital for 5 days.但前提是主语不是时间,而这句话的主语是时间.It has been over a year since we last heard from him.自从我们最后一次收到他的来信,已经有一年多了.
