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。
