7.2不定式作补语
1）有些有动词 +宾语+不定式的构造。例如：
advise
allow
cause
challenge
command
compel
drive派遣
enable
encourage
forbid
force
impel
induce
instruct
invite

warn
persuade
request
send
tell
train
urge
例如；

留意：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，也表达正在举行，过往分词表达主动。
2)有些有动词 +宾语+不定式的构造，不定式的动词频频是be，不定式通俗可以省往。例如：
consider
find
believe
think
declare（宣称）
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.我们晓得他是个蠢人。（to
be不能省往）
典范例题
Charles Babbage is generally considered___
the first computer.
A. to inventB. inventing C. to have invented D.
having invented
谜底： C.通俗没有consider+宾语+be以外不定式的构造，也没有consider+宾语+doing的构造，拂拭A、B、D。consider用动词be以外的不定式作宾补时，通俗要求用不定式的完成式，故选C。
3)有些动词可以跟 there +to be的构造。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边。
You
wouldn’t want there to be another war.你不至于想让另外一场战役发作吧。
