1.樓主表述上存在問題,哎!
2.第一句樓主表達(dá)的想必是：用非謂語動詞做賓語補(bǔ)足語,如果賓語和賓語補(bǔ)足語之間為主謂/主動關(guān)系時,做賓語補(bǔ)足語的非謂語動詞一般使用省略to的不定式.
這種用法一般限制于一些使役動詞（make/let/have）和感官動詞（see/find/watch/notice/hear等）.
如：I saw him enter the classroom.
另：該情況也不是唯一的,有時候也可以用現(xiàn)在分詞或帶to的不定式做賓語補(bǔ)足語.
如：I heard her singing in the classroom.
You must get your child to study hard.
He was seen to enter the classroom.
2.第二種情況和上面的一樣,不過這種情況可以運(yùn)用于幾乎所有的使役動詞和感官動詞中.
且如果是介詞with/without后面出現(xiàn)復(fù)合賓語（賓語 + 賓語補(bǔ)足語）,也會有上述的講法.
如：You must have your clothes washed.
I found my watch lost just now.
With my homework done,I went out to play soccer immediately.
當(dāng)然也不是所有的情況都是如此,如：
With much work to do,I must stay at home alone.
I saw him being beaten by his father last night.
