1998witnessed sth happening ----
Do you witness illegal acts happening in your neighborhood?
确切的说,witnessed 后面的宾语补足语可以使doing也可以是done.具体取决于宾语和宾补之间的主被动关系.本题中sth 与happen 之间是主动关系,因此用happening的形式.
如果是被动,则用done的形式.如：witness Tom hit by his classmate.witness the water polluted by people.

1998 witnessed sth happening/happened ? 那种表达是正确的? was happened,was happening,happen,happened,happening的用法及区别 happened and happening happened,happening为什么? 为什么有what happened却没有what happening,而只能是what is happening,两个动 What happened与What's happening的区别用happen,happening,happened造句英语好的进是sth happened to sb还是sth happen to sb? “what's the happening ”和“what the happened”的区别是什么啊? 英语-什么时候用happened,什么时候用happening something interesting happening/happen/happened/happens happen 固定搭配：是sth happened to 前面happen一定要用过去式的形式吗
