Leaflets have been prepared and ————（send） to our neighboursLast week,a man ------(kill)in his huose and____(find)the next morning.像这种两个动词之间用and连接,两个动词的时态变化是否都要写全 She is the p i have been looking for. have been have been have been have been 关于现在完成时have beenhave been P.P.这里的been表示的是被动语态吗?可为什么会有He has been dead for 3 years.他“被”死了?另外请说明一下什么时候用have been p.p.什么时候用have p.p.另：请勿从句子成 have been还是have been being? have since been 和 have been since have been 和have ever been区别! have broken have been broken? I have been there,have been 是have been in还是have been to的缩写? Have been waiting for have+been是什么时态 have never been是什么意思 have been 的用法?
