请问这HAS BEEN 在里面是什么语法啊？如果是HAVE BEEN 又是什么语法？

现在完成时，都是一样的，
主语是第一，第二人称时，用have
第三人称时，用has

是CS里的吧 -_-!!
是完成被动式，就是炸弹已经被放置

由于bomb是三单，所以要用has
have been是一样的

第三人称单数的现在完成时的被动形式
除第三人称单数的现在完成时的被动形式

指此炸弹已被埋下，has been 是完成时强调动作完成一段时间，have been与主语不配合

han been ,have been 都属于现在完成时。只不过，has been 是主语第三人称单数，一般用于he,she,it之后。have been 一般用于I,we,they...之后。
