He was noticed___basketball on the playground just now

问题描述:

He was noticed___basketball on the playground just now
A to play B play C plays D was playing
还有如果选A是不是被动语态后面的动词结构是什么还是什么?

应该选A
在感官动词see,have,watch,notice等和使役动词let,make之后作宾语补足语的不定式要省去to,变为被动语态时,to不能省.
主动语态示例
I noticed him play basketball on the playground just now.
