go 是非持續(xù)動詞,hasn't gone to school 否定著使用可以,肯定用就不恰當
所以be 是持續(xù)動詞 可以has been away
the old man's son for more than two weeks and he hasn't heard from him since then.
the old man's son for more than two weeks and he hasn't heard from him since then.
填 has been away 但是has been away 不是已經(jīng)回來了么?
has gone away 才是去了沒回來?
