what has happened?为什么用HAS
what has happened?为什么用HAS
what has happened?为什么用HAS
发生了什么事儿?
之所以用HAS 不是HAVE,是发问者不能确定是否有事发生,有几件事发生.
如果问者知道被问者发生了好几件事,只想一一知道这些事都是什么,可用HAVE提问.
表示现在完成时,是指过去的事情对现在有影响或是过去的事情一直持续到现在
现在完成时
过去完成时=has+动词过去时
现在完成时=has/have+过去分词
现在完成时，强调对现在造成的影响．
eg. You look very happy. What has happened？
你看进来很高兴，有什么喜事？
发生了什么事?
表示对过去提问
happen没有被动语态，表示发生了没，就用主动的过去式或者完成时态。
所以句子是what (has) happened,而不是what was happened?
