大家好，我是东南，我来为大家解答以上问题have和has区别顺口溜，have，has，had的区别和用法很多人还不知道，现在让我们一起来看看吧！

　　拓展：have been，has been， had been

　　1.解释：have/has/had+been 都是完成时。

　　2.区别：has/have been是现在完成时,has用于第三人称单数; had been过去完成时,跟前者相比,比前者更为过去;

　　3.例句：

　　（1）He has been doing this work for a period of time.

　　（2）I want to have this book.

　　（3）Have you pass the math exam?

　　（4）Do you ever had a thought that you can win this game?
