分词、不定式作宾补用法要点
★分词、不定式作宾补用法要点
非谓语动词是高中阶段的重点和难点，历来为学生所困惑，所畏惧。学生对非谓语动词的各种形式的用法不甚了解，或知道他们的用法但自己不会用，稍微变一下形式就不知所措，一头雾水。究其原因，还是对非谓语动词的不熟悉，了解的不透，对他们的一般用法掌握的不透彻，似懂非懂。针对这一现象，首先要让学生对几种非谓语动词的基本结构完全了如指掌，还要熟练掌握他们的各种时态语态，各种变形。一方面要让学生懂得他们的基本用法，基本概念，另一方面要多操练，适当的一定量的练习是必不可少。所谓孰能生巧。
一、分词、不定式作宾语补足语的区别
1．感官动词see, watch, observe, look at, hear, listen to, notice 等和使役动词have 后面的宾补有三种形式，即原形动词（不带to 的不定式）、现在分词和过去分词。现在分词表主动或正在进行，过去分词表被动或完成，动词原形表主动和完成。如：
I heard her sing an English song just now.
刚才我听见她唱了一首英文歌。
I heard her singing an English song when I passed by her room yesterday.
昨天经过她房间时，我听见她在唱英文歌。
I heard the English song sung many times.
我多次听到有人唱这首英文歌。
注意：不及物动词的过去分词作宾补表完成和状态。如：
I looked down at my neck and found my necklace gone. (状态)
I was surprised to find my hometown changed so much. (完成)
2．leave 后接三种形式作宾补时，其中的leave 保留了原来之义“留下”，但表达的确切之义应是“使……处于某种状态）。
leave sb. doing sth. 让某人一直做某事（宾语和宾补之间是主谓关系，表示动作正在进行。）
leave sth. undone 留下某事未做（宾语和宾补之间是动宾关系，表示被动和完成，一般以undone, unfinished, unsettled, untouched 为多）
leave sb. to do sth. 留下某人做某事
leave sth. to be done 留下某事要做（不定式表示将来的动作。）
如：It’s wrong of you to leave the machine running.
你让机器一直开着是不对的。（主动，正在进行）
The guests left most of the dishes untouched, because they didn’t taste delicious.
客人们没有动大部分菜，因为它们尝起来不可口。（被动，完成）
He left, leaving me to do all the rest work.
他走了，留下我一人去做剩余的工所有工作。（主动，将来）
We hurriedly ended our meeting, leaving many problems to be settled.
我们匆匆忙忙地结束了会议，留下了很多问题等待解决。（被动，将来）
3．have, get 后接三种形式作宾补时，其中have, get 表示“使、让、叫”之意。
①have sth. done = get sth. done “使/让某事由别人去做”（叫/让某人做某事）。如I’ll have /get my bi ke repaired tomorrow.
此外，have sth. done 还表示“使遭受……”之意。如
Tom had his leg broken while playing football.
Mr. Smith had his house broken into while he was away on holiday.
②have sb. / sth. doing 使/让某人/物持续地做某事（现在分词表示主动，正在进行）get sb. / sth. doing 使某人/物开始行动起来
如：The peasants had the tractor working day and night at the harvest time.
农忙时，农民们让拖拉机夜以继日地干活。
The captain got the soldiers moving toward the front after a short rest.
休息了片刻之后，上尉让士兵们开始朝前线行进起来。
注意：“have sb. doing”若用于否定句中，其中have 有“容忍”之意。如：
I won’t have you spea king to your parents like that.
我不会让你那样子跟你的父母说话。
Don’t have the water running all the time. 不要让水流个不停。
③have sb. do sth. (get sb. to do sth. ) 使/让/叫某人去做某事
如：Mother had me go to the shop and buy some salt.
I can’t get him to stop smoking. He won’t listen to me.
二、下列动词后跟带to的不定式作补语：
advise, allow, ask, beg, cause, encourage, expect, forbid, force, get, intend, invite, like, love, order, persuade, prefer, require, teach, tell, want, warn, wish, 等。如：
①An army spokesman stressed that all the soldiers had been ordered to issue clear warning before firing any shots.
②The teacher asked us not to make so much noise.
③The flu is believed to be caused by viruses that like to reproduce in the cells inside the human nose and throat.
三、不定式、现在分词作宾补小窍门
下列动词后在主动语态中用不带to 的不定式作补语，但在被动语态中要加上to：
它们是“吾看三室两厅一感觉”——5看（look at, see, watch, notice, observe）；3使（make, let, have）；2听（listen to, hear）；1感觉（fell）。以上动词还可用现在分词作宾语补足语（5+3+2+1-2+4）：即以上动词除let, make 外都可以用现在分词作宾语补足语，此外find, catch, keep, have 也可以用现在分词作宾语补足语。
如：At that time, I found him crying in the street.
He was caught stealing. I’m sorry to have kept you waiting for such a long time.
The missing boys were last seen playing near the river.
★不定式、分词作定语用法要点
一、不定式作定语
1．作定语的不定式如果是不及物动词，或者不定式所修饰的名词或代词是不定式动作的地点、工具等，不定式后面须有相应的介词。如：
The Browns have a comfortable house to live in.
There is nothing to worry about.
Please give me a knife to cut with.
Here is some paper for you to write on.
require名词
但是，不定式所修饰的名词如果是time, place 或way时，不定式后面的介词习惯上省去。如：He had no money and no place to live (in).
We found a way to solve this problem (in).
2．当作定语的不定式所修饰的名词或代词是不定式动作的承受者时，不定式既可以用主动语态，也可用被动语态，但其含义有所不同。试比较：
Have you anything to send ? 你有什么东西要寄吗？（不定式to send 的动作执行者是“你”）
Have you anything to be sent ? 你有什么要（我或别人）寄的东西吗？
（不定式to be sent 的动作执行者是“我”或“别人”）
3．用不定式作定语的几种情况：
不定式表将来：
I borrowed some books to read during my holiday.
用来修饰被序数词、最高级或no, all, any 等限定的中心词。如：
He was the best man to do the job.
She was the first woman to win the gold medal in the Olympic Games.
Women and children were the first to get into the lifeboats.
用来修饰的词是抽象名词时，常见的有：ability, chance, idea, fact, excuse, promise, answer, reply, attempt, belief, way, reason, moment, time 等。如：
Do you have the ability to read and write English ?
