人教版 高中英语选修7 Unit 1 Living well Period three grammar 动词不定式的用法学案
Period Two Learning about Language 动词不定式的用法学案动词不定式的基本形式是“to＋动词原形”，有时to可以省略。
动词不定式(或不定式短语)没有人称和数的变化，在句中不能作谓语，但它可以有自己的宾语和状语，在一起构成不定式短语。
动词不定式(短语)具有名词、形容词和副词的特征，其句法作用如下：1．作主语To build the Great Wall took them many years.建成万里长城花费了他们许多年时间。
To play tricks on others is wrong.捉弄别人是不对的。
作主语用的动词不定式(短语)常常用it替代，是先行主语或形式主语，真正的主语——动词不定式(短语)放在后面。
上面两句可改写为：It took many years to build the Great Wall.It is wrong to play tricks on others.2．作宾语在begin，continue，hope，decide，want，wish，try，learn，afford，agree，determine，expect，fail，manage，offer，refuse等动词后通常用不定式作宾语。

动词不定式同它的宾语和状语一起构成不定式短语。
例如：to sell flowers in the street 在街上卖花to speak in the classroom 在教室里讲话不定式省to有四种情况：1、使役动词let, make, have等后接不定式。
例如：Let him go!The boss made the child labors work the whole night.2、would rather, had better后。
例如：You had better stay at home.3、Why…/Why not…后。
例如：Why not have a good rest on Sunday?4.感官动词see, watch, look at, hear, listen to, smell, feel, find，notice等后作宾语补足语，省to。
例如：I saw him dance.注意：这些情况在被动语态中，不可省to.例如：The child labors were made to work the whole night.不定式的主要用法：1.不定式作主语，往往用it作形式主语，真正的主语不定式放至句子的后面。

It's necessary for you to lock the car when you do not use it. 不用车的时候，锁车是有必要的。
It's very kind of you to help us.他帮助我们，他真好。
It seemed selfish of him not to give them anything.他不给他们任何东西，这显得太自私了。
但是，用不定式作主语的句子中还有一个不定式作表语时，不能用It is…to…的句型。
另外，这样的句子，不能用动名词作表语。
2.不定式作表语不定式可放在be动词后面，形成表语。
例如：My work is to clean the room every day. 我的工作是每天清扫房间。
His dream is to be a doctor. 他的梦想是成为一名医生。
3. 不定式作定语不定式做定语通常要放在被修饰的词后，往往表示未发生的动作。
例如：I have a lot of work to do.我有许多事要做。
There was nothing to bring home that morning. 那天早上（他回家时）两手空空。
4. 不定式作状语1）目的状语常用结构为to do , only to do（仅仅为了）, in order to do,so as to do,so（such）…as to…（如此…以便…）。
例如：He ran so fast as to catch the first bus.他飞快地跑以便赶上第一班车。
I come here only to say good-bye to you.我来仅仅是向你告别。
2）作结果状语，可以表示没有预料到的或事与愿违的结果，不定式要放在句子后面。
例如：I awoke to find my truck gone. 我醒来发现箱子不见了。
He searched the room only to find nothing. 他搜索了房间，没发现什么。
3）表原因例如：I'm glad to see you. 见到你很高兴。
She wept to see the sight. 她一看到这情形就哭了。
4）表示理由和条件例如：He must be a fool to say so.You will do well to speak more carefully.5. 不定式作补语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 inventB. inventingC. to have inventedD. 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。
6. It's for sb.和It's of sb.这样的句子中，由于表语形容词性质的不同，导致了不定式逻辑主语标志用for 或of的区别。
1）for sb. 句型中的形容词一般为表示事物的特征特点，表示客观形式的形容词，如easy, hard, difficult, interesting, impossible等：例如：It's very hard for him to study two languages. 对他来说学两门外语是很难的。
2）of sb句型中的形容词一般为表示性格，品德，心智能力，表示主观感情或态度的形容词，如good, kind, nice, clever, foolish, right。
例如：It's very nice of you to help me. 你来帮助我，你真是太好了。
用for还是用of 的另一种辨别方法：用介词for或of后面的逻辑主语作句子的主语，用介词前边的形容词作表语，造个句子。
如果通顺用of，不通则用for。
例如：You are nice.（通顺，所以应用of）。
He is hard.（非所表达的意思，不通，因此用for。
）7.做独立成分。
常用的这类短语有：to be frank(坦白地说), to begin with(首先)等例如：To be f rank, I don’t agree with you.8. 动词不定式的主动形式表被动意义1) 动词不定式作定语与被修饰词之间构成逻辑上的动宾关系，同时与主语构成逻辑上的主谓关系，动词不定式应用主动形式表被动意义。
例如：He has a lot of questions to ask.他有很多问题要问2) 在”be+性质形容词+不定式”,此时不定式用主动表被动。
常见此类形容词：easy, hard, difficult, interesting, heavy, pleasant, good, fit, comfortable, impossible等例如：The water is not fit to drink.这水不适合饮用。
The sentence is hard to understand.这句子很难理解。
3) 在”with+宾语+动词不定式”结构中，若动词不定式与宾语之间为逻辑上的动宾关系，动词不定式一般用主动形式表被动意义。
例如：With a lot of homework to do, I have to stay at home all day.由于很多作业要做，我不得不整天待在家里。
9.动词不定式的否定式在不定式标志to前加上not。
例如：Tell him not to shut the window。
让他别关窗。
She pretended not to see me when I passed by. 我走过的时候，她假装没看见。
10.带疑问词的不定式短语动词不定式前面可以带疑问代词what, which, who或疑问副词how, when, where, why等。
这种结构起名词的作用，在句子里用作宾语、主语、表语等，或者单独使用。
要注意的是，why后面的不定式不带to。
例如：I don’t know what to try next. （作宾语）Where to go is not decided yet.（作主语）注意：单独使用时相当于一个特殊疑问句。
What to do next?(=What will we / you do next?)Why go there?(=Why do we / you go there?)1）一般式表示的动词，有时与谓语动词表示的动作同时发生，有时发生在谓语动词的动作之后，例如He seems to know this. 他似乎知道这事。
I hope to see you again. = I hope that I'll see you again.我希望再见到你。
