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。
第一个是过去时，就问发生了什么事情
第二个强调发生的事情对现在的影响
