改被動語態怎麼改啊
我是這樣做的Her sing this song in English was heard to by most of us
She was heard singing this song in English by most of us
問別人他說要這樣做 爲什麼啊
而且不帶TO的動詞不定式改被動語態不是要加TO麼 hear sb do sth

如果按你的排列的話這個人說的就好像比較符合我說的
他是she was heard to sing this song
hear do sth 改被動 hear to do sth
你是She was heard singing this song
hear do sth 改被動 hear ding sth

解答：

應該是She was heard to sing this song in English by most of us.
sing this song 是動詞短語,前面不可能跟所有格,也不能作爲主語.
所以主語應該爲She.
不帶TO的動詞不定式改被動語態是要加to,但是是加在動詞前面
就是 hear sb do sth改爲被動是：sb be heard to do sth.
總之,改被動語態都是：sb be +動詞過去分詞+ to do sth.
