Mang old people can be seen( dancing) in the parks in the morning.为什么括号里要填dancing?
感官动词被动语态不是要还原to吗?

感官动词see的主动语态有两种形式:
see sb.do sth.看见某人做了某事(变成被动语态时要还原to)
see sb.doing sth.看见某人正在做某事
此题就属于后一种情况,因此填:dancing
句意:早上可以看到许多老年人在公园里跳舞.
再问：那个，我能问一下，see sb doing sth的被动是什么？？？谢谢
再答：是sb. be seen doing sth. 你问题中的句子就是这个结构,因此填: dancing
再问：最后一问，还有什么感官动词像look一样，被动有两种情况？？、谢谢谢。帮忙解决下吧，就这一问了。。。
再答： hear sb. do sth./ hear sb. doing sth. 听见某人做了/正在做某事 watch/notice/observe sb. do sth. 看见某人做了某事 watch/notice/observe sb. doing sth. 看见某人正在做某事 let/ have sb. do sth. 让某人做某事
再问：这些词的被动都有两种情况是吧？
再答：是的, let/ have sb. do sth.一般不用doing 形式.
