不定式作補語
1) 動詞+賓語+不定式
advise allow appoint believe cause challenge command compel consider declare drive enable encourage find forbid force guess hire imagine impel induce inform instruct invite judge know like order permit persuade remind report request require select send state suppose tell think train trust understand urge warn
例句：
a. Father will not allow us to play on the street.
父親不讓我們在街上玩耍。
b. We believe him to be guilty.
我們相信他是有罪的。
Find 的特殊用法：
Find 后可用分詞做賓補，或先加形式賓語，再加形容詞，最后加帶to 的動詞不定式。find后也可帶一個從句。此類動詞還有g(shù)et，have。
I found him lying on the ground.
I found it important to learn.
I found that to learn English is important.
典型例題:
The next morning she found the man ___ in bed，dead.
A. lying B. lie C. lay D. laying
答案：A.find的賓語后面，用分詞或分詞短語，起賓語補足語作用?，F(xiàn)在分詞表達主動，也表達正在進行，過去分詞表達被動。
2) to + be 的不定式結(jié)構(gòu)，作補語的動詞。
Acknowledge, believe, consider, think, declare, discover, fancy, feel find, guess, judge, imagine, know, prove, see, show, suppose, take, understand

A. to invent B. inventing C. to have invented D. having invented
答案：A. 由consider to do sth. 排除B、D。. 此句只說明發(fā)明這一個事實，不定式后用原形即可。而C為現(xiàn)在完成時，發(fā)明為點動詞一般不用完成時，且此處也不強調(diào)對現(xiàn)在的影響，因此不選C。
3) to be +形容詞
Seem, appear, be said, be supposed, be believed, be thought, be known, be reported, hope, wish, desire, want, plan, expect, mean
