三句话都可以翻译成：“发生了什么事?”
What happened?是过去时,单纯问过去发生的事情；
What has happened?强调发生的事情对现在的影响；
What has been happening?强调发生的事情一直延续到现在（现在依然没有结束,还在发生中）.

what happened 是过去时，是从句的一部份，如He told me what happened for him last night.(他告诉我昨天晚上发生的事）。what has happened 是现在完成时，是一个问句，如What has happened for him?（他怎么了）。What has been happening 是现在完成进行时，也是从句的一部份。
