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 不是已经回来了么?
has gone away 才是去了没回来?

go 是非持续动词,hasn't gone to school 否定着使用可以,肯定用就不恰当
所以be 是持续动词 可以has been away

has been away /has gone away 都 是走了还没回来; away--adv. 离开

has/have been to 。。。是去过。。。现在已经回来
