关于be seen doing 和 be seen to do
有 see sb doing 和 see sb to do,那么相应的,被动要还原to,是不是就改成sb be seen to doing 和 sb be seen to do?但好像没有sb be seen to doing 这种说法,只有sb be seen doing.

举个例子来说吧I saw him play football on the playground just now.变成被动语态应该是He was seen to play football on the playground just now.
I saw him playing football when I passed the playground.变成被动语态应该是He was seen playing football when I passed the playground.
see 是感官动词,在变成被动语态时to 不能省略,这个to是动词不定式的标志,跟接动名词形式不是一回事,动名词不是不定式,为什么非要接to呢
