D． 動詞不定式作賓語補足語
不定式可以在“主語+謂語+賓語+賓語補足語”句型中充當賓語補足語。在這壹句型中，賓語是動詞不定式的邏輯主語。
1．在表示感覺的動詞後作賓語補足語，並且不定式都不帶to。這類動詞有：see, hear, feel, watch, notice, observe, look at, listen to等。
I heard them sing yesterday. 昨天我聽見他們唱歌了。
Did you see him go out 妳看見他出去了嗎？
I felt something crawl up my leg. 我感到有什麽東西爬到我腿上了。
註意：轉為被動語態時，原不帶to的不定式要變成帶to的不定式。notice和watch沒有被動語態。
We saw the car stop.
The car was seen to stop. 我們看見這輛車停了下來。2．在使役動詞後作賓語補足語，不定式不帶to。
這類動詞有：make, let, have等。轉為被動語態時，其後通常都用帶to的不定式（have沒有被動語態）。
有些動詞跟不定式作賓語補足語時省去了to，這些動詞有：
壹感二聽三讓四觀看。
壹感：feel 二聽：hear,listen to 三讓：let,have,make 四觀看：observe,see,watch.,look at
What would you have me do 妳要我做什麽？

Let him do whatever he wishes to do. 他想幹什麽就讓他幹吧。

3．在表示心理狀態的動詞後作賓語補足語。這類動詞有：consider, think, believe, discover, find, imagine, judge, suppose, prove等。這類動詞後的不定式通常是“to be+形容詞或名詞”結構，think, consider, find後的to be常可省略。

He proved that theory (to be) very important. 他證明那個理論是很重要的。
