2023年12月大学习英语四级语法常识：不定式作补语
7.2 不定式作补语
1) 动词+宾语+不定式
advise allow appoint believe cause challengecommand compelconsider declare driveenableencourage find forbid forceguess hireimagineimpelinduce informinstructinvite judge know likeorder permitpersuade remind reportrequest requireselectsend state suppose tell think traintrust understandurge warn
例句：
a.Father will not allow us to play on the street.
爸爸不让大家在街上玩耍。
b.We believe him to be guilty.
大家相信他是有罪的。
Find 的特殊使用方法：
Find 后可用分词做宾补，或先加形式宾语，再加形容词，最后加带to 的动词不定式。find后也可带一个从句。此类动词还有get，have。
I found him lying on the ground.
I found it important to learn.
I found that to learn English is important.
典型例题:
The next morning she found the man ___ in bed，dead.
A. lying B. lie C. lay D. laying
答案：A.find的宾语后面，用分词或分词短语，起宾语补足语用途。目前分词表达主动，也表达正在进行，过去分词表达被动。
2) to + be 的不定式结构，作补语的动词。
Acknowledge,believe,consider,think,declare,discover, fancy,feel find,guess, judge,imagine,know, prove,see, show,suppose, take, understand
We consider Tom to be one of the best students in our class.
大家觉得汤姆是班上最好的学生之一。
典型例题
Charles Babbage is generally considered___ the first computer.
A. to inventB. inventing C. to have invented D. having invented
答案：A. 由consider to do sth. 排除B、D。. 此句只说明创造这一个事实，不定式后用原形即可。而C为目前完成时，创造为点动词一般不需要完成时，且此处也不强调对目前的影响，因此不选C。
3) to be +形容词
Seem, appear,be said,be supposed, be believed,be thought,be known, be reported,hope, wish, desire,want, plan, expect, mean…
The book is believed to be uninteresting.
大家觉得这本书没的意思是。
4)there be+不定式
believe, expect, intend, like, love, mean, prefer, want, wish, undrstand
We didnt expect there to be so many people there.大家没料到会有那样多人在哪儿。
注意 ： 有的动词需用as 短语做补语，如regard, think believe, take, consider.
