They ________(leave)their hometown since 3 years ago.
填have been away
还是have been away from
解释一下理由的啦！
填have been away
还是have been away from
解释一下理由的啦！
应该是have been away from
固定词组be away from somewhere
如果用be away 后面就不可以加其他成分,如果要加其他成分就需要介词from
上面不是动词leave吗,怎么变成have been away和have been away from拉?如果是leave,那么是had left,因为后面since 所引导的是过去完成时的标志;如果是下面的,那么是have been away,因为介词不能和物主代词一起连用!
动词有延续性和非延续性的我晕 当然要用他给的咯
谁说介词不能和物主代词一起连用?
我选They have been away from their hometown since 3 years ago.
have been away from
