（1）动词＋副词，如black out;?
（2）动词＋介词，如look into;?
（3）动词＋副词＋介词，如look forward to。

write down写下 call up打电话给……
cheer up让某人开心 set up建立

give up放弃 try on试穿
【注意】在“动词＋副词”结构中，如果后面的宾语是代词，代词应放在动词和副词的中间。如try it on, put them up, put it off, cheer him up等。
十九、动词不定式
动词不定式是一种活跃的非谓语动词。它在句子可起名词、形容词或副词的作用，可在句子中作主语、宾语、定语、状语或宾语补足语。动词不定式的形式是“to+动词原形”，但to有时要省略。动词不定式在具体运用时，用不用to，取决于谓语动词的用法。
1.带to的不定式结构
（1）能直接跟带to的不定式结构的动词主要有：want, ask, tell, hope, learn, try, decide, forget, remember, like, love, stop等。
例句:She likes to play the piano.
(2) 动词不定式的否定形式是在不定式前直接加not, 即not to do sth.。
例句：Jim told me not to wake up Kate.
2.不带to的不定式结构
（1）在固定词组had better 之后。注意：had better do sth. 的否定形式是had better not do sth.。
(2) 在let, make, see, feel, watch, hear等感官或使役动词后，要跟不带to的动词不定式作宾语补足语。
(3) 在引导疑问句的why not之后。
“Why not+不带to的不定式”是Why don’t you do…的省略，可以用来提出建议或劝告。
Why not take a holiday = Why don’t you take a holiday
3.句法功能
（1）动词不定式作主语
例句：To master a language is not an easy thing.
【注意】动词不定式作主语时可以放在后面，而用it作形式主语放在原主语的位置上。
例句：It’s necessary to find the witness.
（2）动词不定式作定语
动词不定式作定语，要放在它所修饰的名词或代词的后面。
例句：I have nothing to say on this question.
（3）动词不定式作宾语
有的及物动词要求跟复合宾语（即宾语+宾语补足语）。如果其中的宾语是不定式短语，则必须将形式宾语it放在宾语的位置上，而将不定式短语（真正的宾语）放在宾语补足语之前。
例句：I find it useful to learn English well.
（4）动词不定式作宾语补足语
动词不定式作宾语补足语是动词不定式用法的一个重点，学习时要注意以下三种情况：
A.作动词ask, like, tell等的宾语补足语时，动词不定式符号to不可以省略。
例句：He asked me to talk about English study.
B.作使役动词let, have, make以及感官动词feel, hear, see, watch等的宾语补足语时， 动词不定式符号to要省略。
例句：The teacher made him say the word like this.
C.作动词help的宾语补足语时，动词不定式符号to可以带，也可以不带。
例句:Could you help me (to) carry the heavy box
(5)动词不定式作状语
动词不定式及其短语具有副词的特性，可在句中用作状语。
放在句首也可以放在句尾表示目的等。
例句：He stopped to have a rest.
（6）跟在作表语的形容词或过去分词的后面。
例句:I’m sorry to hear that,
4.用在too…to…结构中。
例句：He is too young to understand all that.
5.疑问词+不定式

I was doing the work in the garden yesterday. It was a soft evening and I was making the most of it when I heard a neighbor’s voice coming from the path out of our garden.
“That’s no place to be sleeping!” he said.
I found there was a man lying on his back on the path with his eyes closed. I recognized him. I had seen him doing the drunkard’s (酒鬼) walk along that path several times.
I stopped to walk out. “Do you need some help ” I asked.
He opened his eyes and said, “Probably.” Then he told me because of arthritis (关节炎) he couldn’t walk well at the most of times. I thought I should do it when he asked to help him go home where he lived a few hundred metres away.
I tried to let him walk under his own strength with me guiding him but that was getting us nowhere. It was easier to carry him, but that would be a real insult (侮辱) to him. So, I held his left hand with my left hand and grabbed his belt with my right hand. Then we started walking slowly.
On the way he told me his name, what he had worked as, what holidays he had been, how wonderful his granddaughter was, what his wife’s name was — and what a hard time she would give him when he got home!
Thank goodness! His wife wasn’t in when we walked forty-five minutes back to his home.
If we wait until we feel good about helping before we help, then people will go unhelped and we will become the ones who end up walking on by.

B．When the writer was walking on the path.
C．When the writer almost ended up his work.
D．When the writer wanted to begin his work.
27．Who was lying on the path
A．A neighbor. B．The writer’s wife. C．A drunkard. D．A gardener.
28．Why didn’t the writer carry the man
A．Because he could walk well by himself.
B．Because it would be an insult to him.
C．Because it was only a few hundred metres away.
D．Because his wife would give him a hard time.

A．The man was a talented person.
B．The man enjoyed having holidays.
C．The man’s wife was always kind to him.
D．The man loved his granddaughter very much.
30．What does the story want to tell us

Dear Sir or Madam,
Thank you for reading my letter. I’d like to be a volunteer for Winter Olympic Games. Because I like sports. In school, I often take part in all kinds of activities. I am good at English. I listen to English news on the radio every day and can communicate with foreign friends freely. I am outgoing, too. I can get along with them and give them a hand whenever they are in need.
I think volunteer work is great. I hope I can be a member of Winter Olympic Games. I’m looking forward to your reply.
Yours,
Li Hua
