e seen
be heard
be watched
be noticed
be found
be made
使用时要注意:
在主动语态中,make ,let ,hear ,see ,watch ,notice 等词,其后跟省略to的动词不定式(动词原形),在变为被动语态时,必须还原动词不定式符号to.如:
We heard him sing this song in the room.
He was heard to sing this song in the room.
The boss made him work 14 hours a day.
He was made to work 14 hours a day.
I see him walk to school
He is seen to walk to school.

see hear watch notice find make被动语态后是不是一定要加to? 请问：see,watch,notice,hear,feel,observe这些在被动语态里都要还原to see,watch,notice,hear,feel,observe等这些在被动语态里都要还原to, 那个 feel,hear,notice,see,watch ...这些动词后的不定式做宾补to要省略么? 感观动词see,watch,notice,hear feel,find各造句三个. 为什么被动语态make 后面加to? 英语高手来看看!（see、 hear、 notice、 find、 feel、 listen to、look at、（感关于make.let.have使役动词与see.watch.notice.observe.hear.feel感官动词作谓被动语态后是不是都要在动词前加TO? 帮忙解释let；see；watch；fell；make后面的动词用原型,但在被动语态中用to do,什么时候要用?怎么用 have see watch hear make get 后面加的动词是什么形式被动语态后如果要再加动词是不是要先加to
