2021年高考英语专题复习：动词不定式 动词不定式的基本形式是“to+动词原形”有时可以不带to，否定式：not + (to) do。动词不定式没有人称和数的变化，在句子中不能作谓语，但具有名词、形容词、副词的特征，可以担任主语、表语、宾语、定语、状语和宾语补足语。动词不定式仍保留动词的一些特点。
一、不定式的句法功能： （1）作主语： To finish the work in ten minutes is very hard. 十分钟之内完成这项工作是很难的。 To lose your heart means failure. 灰心意味着失败。 动词不定式短语作主语时，常用it作形式主语，真正的主语不定式置于句后，上面两句可用如下形式：
________________________________________________________ ________________________________________________________ 常用句式有： 1、It+be+名词+to do。 2、It takes sb.+some time+to do。 3、It+be+形容词+of/for sb +to do。 （1） 如果句中的形容词表示人物特征或品质，常同of搭配构成“It is + 形容词＋of＋代词（名词）＋不定式”句型。如： bold ，brave, careful, careless, considerate, cruel, rude, generous, :right，wrong, kind，nice，good，polite，clever，wise， foolish, silly等。（2）表示事物性质的形容词如easy, difficult, hard, important, impossible, possible, safe, dangerous, necessary常同for 搭配。
1. Sometimes C to place physics and chemistry into separate categories. A. that is difficult B. is difficult C. it is difficult D. that it is difficult 2. The teachers don't know A to start and run a school. A. what it takes B. what they take C. what does it take D. what takes
3. It is wise A the experiment that way. A. of him to do B. for him to do C. of his doing D. that he do （2）作表语： 1．主语和表语都是不定式（其含义往往一是条件，一是结果），如： To be kind to the enemy is to be cruel to the people. To do that would be to cut the foot to fit the shoe. 2．主语是以aim, duty, hope, dream, idea, intention, purpose, mistake, plan, proposal, job, suggestion 等为中心词的名词词组，或以 what 引导的名词性从句表示，后面的不定式说明其内容，如：
My idea is to climb the mountain from the north. Your mistake was not to write that letter. My suggestion is to start work at once. What I would suggest is to start work at once. 注：在某些句型中，当主语部分有动作动词do 时，作表语的不定式可以省略符号 “to”，如：
All we have to do is push the button. The only thing I can do now is go on by myself. All I could do was send him a telegram.
1. My dream is an outstanding architect after graduation. A. to becoming B. become C. becoming D. to become
（3）作宾语： 1．“动词 + 带 to 的不定式结构”。这类动词常见的有：afford, agree, arrange, ask, choose, decide, demand, desire, expect, hope, learn, manage, offer, pretend, promise, refuse, want, wish, like, hate, prefer, continue, try, start, forget, mean, intend, begin, 等，例如：
I’ve arranged to meet him at ten o’clock. I didn’t expect to find you here. 注 ：如果作宾语的不定式结构有自己的补语，则应使用先行 it，把不定式后置，例如： I find it difficult to understand him. We thought it wrong not to help her. They found it impossible to get everything ready in time. 2．“动词 + 疑问词 + 带 to 的不定式结构”。（这种不定式结构接近一个名词从句）。这类动词常见的有：tell, advise, show, teach, find out, decide, discuss, learn, forget, inquire, know, explain, remember, see, understand, wonder 等。
疑问词（也称连接代/副词）有：what, where, who(m), when, how, whether, which（why 除外），如：
I don’t know what to do / where to go / who(m) to ask / when to stop / how to get there. I haven’t decided whether to sell it or not. We must find out what to do next / where to put it. 3．“介词+不定式结构”。不定式结构一般不可作介词宾语, 只有在个别场合, 即在含有否定意义的带有介词 except 和but的结构中才能这样用，例如：
He seldom comes except to look at my pictures. The child did nothing except weep. She can do anything but sing. ①前面有do，后面省to。如： They did nothing but complain. 他们老是一个劲地抱怨。 _____________________________________________除了看电视，他从不干任何事。 I could do nothing except agree. 我除了同意，没有别的办法。 She was willing to do anything except tell me her mane. 她怎么都行，就是不肯把她的名字告诉我。
②前面没do，后面带to。如： Nothing remains but to die. 除了死，没有别的办法。 __________________________________________除了等，我没有别的选择。 It had no effect except to make him angry. 除惹他生气外，没产生任何效果。 I can do nothing for them except to send them money. 我除了给他们寄钱以外，什么也不能帮他们。

A. admit B. admitted C. admitting D. to admit 4. She pretended ___A____ me when I passed by. A. not to see B. not seeing C. to not see D. having not seen
（4）作宾语补足语： 1．带to的不定式作宾补 a．可以用带to的不定式作宾补的动词常用的有ask, tell, order, invite, beg, get, allow, wish, want, encourage, advise, warn等。例如：
The teacher asked us to finish our homework．老师叫我们完成家庭作业。 She wanted him to sing for her friends．她想让他为她的朋友唱歌。 The policeman told the boys not to play in the street．警察告诉孩子们别在街上玩耍。 b．在动词think，believe，know，find， understand，take等之后，作宾补的不定式多由“to be ＋adj．”构成。例如：
