D．动词不定式作宾语补足语
不定式可以在“主语+谓语+宾语+宾语补足语”句型中充当宾语补足语。在这一句型中，宾语是动词不定式的逻辑主语。
1．在表示感觉的动词后作宾语补足语，并且不定式都不带to。这类动词有：see,
hear, feel, watch, notice, observe, look at, listen to等。
I heard
them sing yesterday.昨天我听见他们唱歌了。
Did you
see him go out你看见他出去了吗？
I felt
something crawl up my leg.我感到有什么东西爬到我腿上了。
注意：转为被动语态时，原不带to的不定式要变成带to的不定式。notice和watch没有被动语态。
We saw
the car stop.
n The car was seen to stop.我们看见这辆车停了下来。
n
2．在使役动词后作宾语补足语，不定式不带to。
这类动词有：make,
let, have等。转为被动语态时，其后通常都用带to的不定式（have没有被动语态）。
有些动词跟不定式作宾语补足语时省去了to，这些动词有：
一感二听三让四观看。
一感：feel 二听：hear,listen
to 三让：let,have,make 四观看：observe,see,watch.,look
at

he had often made his little sister cry, today he was made to cry by his little
sister. 虽然经常是他弄哭小妹妹，但今天他却被小妹妹弄哭了。
3．在表示心理状态的动词后作宾语补足语。这类动词有：consider,
think, believe, discover, find, imagine, judge, suppose, prove等。这类动词后的不定式通常是“to be+形容词或名词”结构，think,
consider, find后的to be常可省略。
We
consider him (to be) a good teacher.我们认为他是一个好老师。
He
proved that theory (to be) very important.
他证明那个理论是很重要的。
I
thought her (to be) nice and honest the first time I met her.我第一次见到她的时候就认为她人很好，很诚实。

like, prefer, hate, want, wish, expect等。

prefer you to leave him alone.我希望你不要打扰他。

want there to be any trouble.我不想有任何麻烦。
5．动词advise,
allow, ask, beg, command, tell, invite, force, oblige, get, help, encourage,
persuade, permit, remind, request, order, warn, cause等后面，多接不定式短语作宾语补足语。
