题目

have done和 have been的区分 有些情况写 have been未必是被动语态啊
比如 这个句子：There have been a great number of accidents lately.最近事故很多,这并不是一个被动句啊
同理：I haven't been very successful so far.请问如何区分have been 和have done
比如 Up till now he has won five prizes.
这个句子 可不可以说成 Up till now he has been won five prizes
此处的 been 是不是 be动词的过去分词？
He has never been abroad before.这里的been

答案

have been 和have done 都是现在完成时
have been 表示状态,非被动语态（a great number of accidents 和successful是一种状态)
have done 表示动作（won five prizes是一个发生在过去并对现在造成影响的动作）
并且说成Up till now he has been won five prizes就变成了被动语态,而他不是被赢的,不能用被动语态.
been 就是be的过去分词（has+动词过去分词）
He has never been abroad before也是表示一种状态.
