非谓语动词（不定式、分词）作宾语补语小结。
非谓语动词作宾语补语（在被动语态中，是主语的补语）主要体现在一些动词或短语的用法上，因此必须熟记这些词。一般说来，这样的动词有三类：
⒈以带to的不定式作宾补的动词有：ask, beg, tell, order, force(drive),require,allow,permit,forbid,like,get,cause,encourage,expect,want,invite,sign,wave,love,prefer,teach,prepare,train,help(补语也可不带to),dare, cause, set(使),warn,还有词组,wait for, call on(号召),depend on, 而choose, find, know, consider一般可以用to be作宾语补语。如：
*He dared me to jump across the stream.
他用激将法要我跳过那条小溪。
*I’ll prepare her to face the difficulty.
我要让他做好准备去面对困难。
*In this way, you will be able to train them(to) read faster.
用这种方法你能训练他们阅读得更快。
*He is considered to be an honest boy.
人们认为他是一个城市的孩子。
⒉以不带to的不定式（被动语态时，要带to）和分词作宾语补语的动词是表示感觉的动词和使役动词。它们是feel, hear, listen to, look at, notice, observe, see, watch和have, let, make。这些词中，let只有用不定式作宾语补语的用法，他一般不用被动语态。have也不用被动语态。make没有用现在分词作宾语补语的用法。
*The boss made the workers work more than ten hours a day.
这个老板迫使工人们每天工作十多个小时。
*Don’t have children learn so many subjects before they go to school.
上学前，不要让孩子们学习太多的学科。
*Jack saw a stranger go into his house.
捷克看见一个陌生人进了他的家。
⒊除了感观动词和使役动词外，下列动词一般用现在分词作宾语补语：catch(发觉),dislike, find, get, keep(使得),leave(让), set(使), like, love。下列动词可以用过去分词作宾语补语：get, make, find, want, order, wish, leave.如：
*When camping in the mountain, we got the fire burning all the night.
在山上宿营时，我们让火彻夜燃烧。
*When she walked near to the door, Lily found the door locked.
当黎黎走近房门时，她发现门锁着。
注意：
1)不定式根据语境的需要可以有被动式或完成式。现在分词也有被动式，如：
*They ordered the fire to be put out at once.
他们要求立即将火扑灭。
*When she awoke, she found herself being looked after by a nurse.
醒来时，她发现自己还由一名护士照料着。
*The book is said to have been translated into many languages.
据说该书已被译成多种文字。
2)在被动语态中宾语补语变成主语补语，感观动词和使役动词后的不定式必须将加上。如：
*The boy was seen to enter that empty house.
有人看见那个孩子进了那间空房子。
*Birds are seldom heard to sing at night.
