been的用法
Shawn's been trying for months to find a job.
为什么要用been?

短暂性动词不可以和一段时间连用,所以当一些短暂性动词和一段时间连用时,要把短暂性动词转化成延续性动词或状态.像arrive ,come,go 等往往改为be+介词at/in ;leave 往往改为be away (from...) stop,end,finish往往改为be over;begin/start 往往改为be on
The train has been in the station for two hours
这句话的意思是：火车两小时前来到车站,现在还在车站,在车站已有两小时了.而“来到车站”这个动作是不可能持续两小时的.
He has been away from Tokyo along “离开”这个动作是不可能持续很长时间,所以用be away (from...)这个状态,并不是简单地去掉非延续动词

been的用法Shawn's been trying for months to find a job.为什么要用bee my sister has been engaged for two months中为什么要用been? He has been there for six months.has been后面为什么不加to?还有为什么要加fo it's hard (to find) a job,为什么不能用to look for/to find out How's you been?It's been two months.这两句话正确吗?been的具体用法是?
