1) 有些有动词+宾语+不定式的结构。例如:
advise |
allow |
cause |
challenge |
command |
compel |
drive 驱使 |
enable |
encourage |
forbid |
force |
impel |
induce |
instruct |
invite |
like/love |
order |
permit |
make |
let |
have |
want |
get |
warn |
persuade |
request |
send |
tell |
train |
urge |
例如;
Father will not allow us to play on the street. 父亲不让我们在街上玩耍。
The officer ordered his men to fire. 长官命令士兵开火。
注意:有些动词如make,have,get,want等可用不定式作做宾补,也可用分词作宾补。现在分词表达主动,也表达正在进行,过去分词表达被动。
2) 有些有动词+宾语+不定式的结构,不定式的动词往往是be,不定式一般可以省去。例如:
consider |
find |
believe |
think |
declare(声称) |
appoint |
guess |
fancy(设想) |
guess |
judge |
imagine |
know |
例如:
We believe him to be guilty. 我们相信他是有罪的。
We know him to be a fool. 我们知道他是个笨蛋。(to be 不能省去)
典型例题
Charles Babbage is generally considered ___ the first computer.
A. to invent B. inventing C. to have invented D. having invented
答案:C. 一般没有consider+宾语+be以外不定式的结构,也没有consider+宾语+doing的结构,排除A、B、D。consider用动词be以外的不定式作宾补时,一般要求用不定式的完成式,故选C。
3) 有些动词可以跟there +to be的结构。例如:
believe |
expect |
intend |
like |
love |
mean |
prefer |
want |
wish |
understand |
|
|
例如:
We didn't expect there to be so many people there. 我们没料到会有那么多人在那里。
You wouldn’t want there to be another war. 你不至于想让另外一场战争发生吧。
