What has happened和What was happened区别

What has happened和What was happened区别 what happened ?和what has happened ?的区别 what happened to you 和what has happened to you有什么区别 What has happened和What happened的区别另问过去时与现在完成时的区别 what happened 和what has happened 有什么区别么请问 what happened to 和what happened what has happened?为什么用HAS what happened what has happenedwhat happened what has happened 在语义上有什么区别吗 what's happened 中的“s”是has吗?还是is?还是was?还是什么?what's happened和what happened有区别吗?如果别人问what's happened应该怎么回答?问what happened又该怎么回答? 下列两句的句型区别和意思区别在哪?1,What happened 2,What has happened what has happened.这个句式有错吗 what has happened是什么时态的句型 do you know what ( ) just now.A.was happened B.happened C.has happened D.has been happened 是what has happened to还是what has happened at快,还有后面加什么! What happened和what's happened有什么区别呀? I wanted to know_to him.为什么填what happened而不是what has happened? No matter what ( )happened to you.用have还是has what has happened to you这不是被动语态吗?
