I have been selling I have been trying I have ever been I too have been I have been to. I have been I have been in. I have been there,have been 是have been in还是have been to的缩写? 关于时态的问题have beenhave been 和have had been有什么区别?原句是这样的：I've heard has been good.有have也有has 关于Have you been Have you ever been to Peking?yes,i have been there -----Athree timesBfor three timesCfor two months(我主要想问c为什么不对) i have always been there i have never been there I HAVE NEVER BEEN,能否说I never have been I have been so serious I have been so serious I-have-been-at-home I have always been you I have been loving you I have been a person . I have never been away!
