we heared him sing the song in the next room 改为被动语态

问题描述:

we heared him sing the song in the next room 改为被动语态

he was heard sang a song in the next room by us.

He was heard to sing the song in the next room (by us) .
hear+不带to的动词不定式,被动语态要还原to。
PS:你单词写错了哦。hear的过去时是heard。是不规则变化

He was heard to sing the song in the next room.
感官动词在被动语态中,要恢复动词不定式to

He was heard sing the song in the next room by us.
