高考英语不定式的用法及真题练习
高考英语不定式的用法及真题练习不定式不定式的用法：不定式的否定形式是在所有的不定式to 前加not(1) 作主语不定式短语作主语时，往往放在谓语之后，用it作形式主语。
To see is to believe．眼见为实。
It is right to give up smoking.戒烟是对的。
It is kind of you to come to see me.(2) 作宾语不定式短语作宾语时，如果还带有宾语补足语，往往把不定式宾语放在宾语补足语之后，而用it作形式宾语。
e.g. He wanted to go．他想走。
I find it interesting to work with him.我发现和他一起工作有趣。
有作形式宾语, 主要有两类动词:●谓语动词是make; find; believe; think; feel等时, 常用it作形式宾语●谓语动词是表好恶的词, 如: like; dislike; hate; appreciate常用it作形式宾语They made it possible to finish the task in two days.I find it difficult to study English well.I hate it when a person speak with his mouth full.We will appreciate it if you help us.(3) 作宾语补足语He asked me to do the work with him．他叫我跟他一起做这个工作。
注意：1）在feel, hear, listen to, look at, notice, observe, see, watch, have，1et, make等词后的补足语中, 不定式不带to。
+ 不定式强调动作的全过程;+ 现在分词强调动作与宾语之间存在主动关系, 及动作正在进行;+ 过去分词强调动作与宾语之间存在被动关系, 及动作已经完成. 如:I must see my child cross the street.I saw the thief stealing her money.You will see many problems settled in this way.2）但是这些句中如果变成被动结构时，就必须带to。
英语不定式(短语)用法全解析
英语不定式（短语）用法全解析摘要本文介绍了英语不定式（短语）的定义、形式和用法，并重点分析了不定式（短语）在句中作主语、表语、宾语和补足语的功能和特点。
本文还提供了一些例句和练习题，帮助读者理解和掌握不定式（短语）的用法。
一、什么是不定式（短语）1.1 不定式的定义不定式是动词的一种非谓语形式，在句中不能单独作谓语。
不定式具有动词的性质，它可以有自己的宾语和状语，从而构成不定式短语。
不定式也具有非动词的性质，相当于一个名词、形容词或副词，可以在句中担任主语、宾语、宾语补足语、表语、定语和状语等成分。
1.2 不定式的形式不定式的基本形式是由不定式符号to+动词原形构成，在某些情况下to也可省略。
不定式还可以有形式的变化，即一般式、进行式、完成式和被动式。
形式结构意义一般式to do表示与谓语动作同时或几乎同时发生，或在谓语动作之后发生的动作进行式to be doing表示正在进行的或与谓语动作同时发生的动作完成式to have done表示在谓语动作之前发生的动作完成进行式to have been doing表示在谓语动作之前发生并且一直进行着的动作被动一般式to be done表示被动意义，即逻辑上的主语是这个不定式表示的动作的承受者被动完成式to have been done表示被动意义，且在谓语动作之前已经完成的动作否定形式not to do表示否定意义，即逻辑上的主语没有做或不会做这个不定式表示的动作二、不定式（短语）在句中的用法2.1 不定式（短语）作主语不定式（短语）具有名词的特征，可在句子中充当主语。
不定式（短语）在句首作主语To know oneself is difficult. 人贵有自知之明。
用it作形式主语在很多情况下，人们通常用it作为形式上的主语，而把不定式（短语）移到谓语之后，使句子结构显得平稳一些。
It's rude to turn your back to your teacher and refuse to answer. 背对着老师，拒绝回答问题是不礼貌的。
动词不定式归纳(含练习及答案)
动词不定式归纳定义：不定式的to和介词to需要被区分开，不定式的to后接动词原形，介词to后接名词、代词或动名词。
不定式作动词宾语He decided to invite all of his classmates to attend the holiday at the beach. 不定式作宾语He promised not to tell anyone about it.如果宾语有自己的补语，则常用it作形式宾语，而把真正作宾语的不定式放在后面放在后面，常带有形式宾语的动词有：believe. Consider. Feel. Find. Know. Make . regard例：we think it important to obey the laws. √we think to obey the laws is important. ×I know it impossible to finish so much homework in a day.不定式作介词宾语当介词but、except、besides前面有行为动词do及其各种形式时，介词后面的不定式可以省略to，否则不省略。
What do you like to do besides play football？We have no choice but to wait.个别介词可以用“疑问词+不定式”作宾语The boy has him own idea of how to finish it.不定式起形容词作用作定语不定式作定语用来修饰名词或代词，置于它所修饰的词后，而且放在其他后置定语的后面。
同时与它所修饰的名词或代词形成逻辑上的动宾关系或主谓关系。
He always has a lot of meetings to attend. 不定式to attend 和名词meetings 形成动宾关系The next train to arrive was from Seattle. To arrive 和train形成主谓关系Do you have anything interesting to read?如果作定语用的不定式是不及物动词，就要加上介词，使被修饰的这个词成为这个介词的逻辑宾语。

高三英语一轮复习专项练习：不定式
不定式考点透视Ι不定式的时态与语态主动形式：一般式(to do)表示的动作通常与谓语所表示的动作（状态）同时发生，或是在它之后发生。
1.I want to have a cup of tea. 我想喝杯茶。
（同时）2. We expect him not to come. 我们希望他不来。
（之后）完成式(to have done)表示的动作在谓语动词所表示的动作（状态）之前发生。
She was said to have been rich. 据说她曾经富有过。
进行式(to be doing)表示当谓语动词所表示的动作发生时，不定式表示的动作正在进行。
He pretended to be waiting for someone. 他装着在等人。
被动形式：不定式的被动语态只有一般式(to be done)和完成式(to have been done)。
表示不定式的逻辑主语是不定式所表示的承受者时，不定式一般用被动语态。
如：1.He asked to be sent to work in the country. 他要求送到农村去工作。
2. He thought it an hour to have been invited to the party. 他被邀请参加聚会感到很荣幸。

不定式用法与高考试题
不定式用法与高考试题湖南隆回一中罗玉南不定式的几种形式与高考试题湖南隆回一中罗玉南 422200一、不定式的一般式不定式的一般式，即“to＋动词原形”，表示的动作通常与谓语动词同时或几乎同时发生，或之后发生。
不定式一般式与句子主语、宾语或for sb.to do sth．结构中的介词宾语有逻辑上的主谓关系。
如： I am glad to see you．（to see与am glad 同时发生，其逻辑主语是I） No one could tell me where to get the book..（to get在could tell之后发生，其逻辑主语是宾语me）【NMET 95】 We agreed ____________ here but so far she hasn't turned up yet． A．having met B．meeting C．to meet D．to have met析：答案C。
agree to do sth．意为“同意做某事”，不定式用一般式，表示在agree之后发生的动作。
meet不会发生在agree之前，所以不用完成式。
二、不定式的完成式 1 不定式的完成式，即“to have ＋过去分词”，表示动作在谓语动作之前发生，的逻辑主语也是句子的主语或宾语。
如： He is said to have written a new book about workers．（to have written发生在is said之前，其逻辑主语是he） I am sorry to have given you so much trouble． （to have given发生在am sorry之前，其逻辑主语是I） 【MET 93】 Charles Babbage is generally considered ____________ the first computer． A．to have invented B．inventing C．to invent D．having invented析：答案A。
英语语法-不定式用法及习题
目录1 不定式的语法功能 (3)2 不定式的几个主要句型及应注意事项 (12)习题 (22)答案 (23)什么是不定式呢？请看下面例句：例：I want to go.我想去。
在这个句子中有两个表示动作的动词：一个是want，另外一个是to go。
want是这个句子的主要动词，它会随着主语的人称、数和时态而变化，例如：He wants～（主语是第三人称，现在时）；He wanted～（过去时）。
to go，不管主语的数、人称和时态如何变化，它永远保持《to+动词原形》的形式，to go就是不定式。
所以说，不定式中所谓“不定”是不受主语的数（单数或复数）和人称（第一人称、第二人称、第三人称）以及时态、语态等的影响或限定的意思。
例如：一般现在时：He wants to go.一般过去时：I wanted to go.一般过去时的被动语态：They were asked to go.在上述三句中，主语、时态、语态有变化，但不定式to go不受影响，毫无变化。
总结：动词不定式的基本形式是《to +动词原形》，有时可以不带to。
动词不定式没有人称和数的变化，在句子中不能作谓语。
（但可以担任除谓语外的任何成分——主语、表语、宾语、状语和宾语补足语。
）动词不定式仍保留动词的特点，即它可以有自己的宾语和状语。
动词不定式和它的宾语或状语构成不定式短语。
注意不定式前面的to（或称为小品词）和介词用的to是不同的。
介词to 后面要跟名词或代词的宾格，或相当于名词的词及短语做它的宾语。
而不定式的小品词to后面要跟动词原形。
listen to me（to是介词）to read the book（to是不定式的小品词）1 不定式的语法功能不定式《to +动词原形》在句子中有各种作用，一般可归类为三种基本用法，如下：1.作名词的用法2.作副词的用法3.作形容词的用法。
不定式的形式担当主语的词一般的句子都以名词（如Tom，the pen…）或代名词（如he，this…）作为主语。

非谓语动词----不定式在英语中，不作句子谓语，而具有除谓语外其他语法功能的动词，叫做非谓语动词。
非谓语动词有动词不定式（the Infinitive）；动名词（the Gerund）; 分词（Participle）。
#1.不定式的句法功能：1）作主语：eg. To finish the work in ten minutes is very hard. / To lose your heart means failure.动词不定式短语作主语时，常用形式主语it作形式主语eg. It is very hard to finish the work in ten minutes.→It is very hard for us to finish the work in ten minutes只用of 不用for的情况: 表语形容词是表示人的性格特征时，如kind, good, clever, stupid , etc ，用来表示动作的执行者。
eg. It’s very kind of you to help me.2）作表语：eg. Her job is to clean the hall. / He appears to have caught a cold.3）作宾语：eg. She wishes to be a doctor. / I forget to ring him up yesterday.有时用it作形式宾语，真正的宾语（不定式）后置，放在宾语补足语后面，例如：eg. Marx found it important to study the situation in Russia.4）作宾语补足语：eg. Tell the children not to play in the street.有些动词如make, let, have, see, watch, hear, feel,等与不带to的不定式连用，但改为被动语态时，不定式要加to, 如：eg. I saw him cross the road. →He was seen to cross the road.I saw a little girl run across the street.→A little girl was seen to run across the street.5）作定语→基本结构eg. I have a lot of work to do ./ Now I have no pen to write with(主动形式表被动关系+不定式动词是不及物动词时后加介词)eg. I have a meeting to attend. / He found a good house to live in.The child has nothing to worry about.如果不定式修饰time, place, way，可以省略介词：eg. He has no place to live. / This is the best way to work out this problem. exercise: which one is right? (B)I’ll go to Shanghai. Do you have anything to take ? (A)to be taken? ( B )→名词后加不定式解释所修饰名词的内容：eg. We have made a plan to finish the work.Have you thought of a way to solve the problem?→名词后加不定式表示即将发生的动作eg. During the week to come, we’ll have several meetings.6）作状语：→三层关系：eg. He worked day and night to get the money.(目的)He hurried to the station only to find the train had gone.(结果)He jumped with joy to hear the news (原因)注意不定式放句首时，逻辑主语与句子主语要一致：wrong：To learn English well, a dictionary is needed.right: To learn English well, he needs a dictionary.→Sb.+be +adjective+to do sth. 不定式表示产生某种情绪的原因eg. She’s ready to help others . / We are glad to see you here.→Sb./sth.+be+adjective+to doeg. The chair is very comfortable to sit on./ The question is difficult to answer.(主语和不定式动词是被动关系，但只能用主动语态，如不定式动词是vi,则加相应的介词)7) what/which/how/when etc +to do ….. 不定式的复合结构eg. My question is when to start the street.Whether to do it or not has not been decided8）作独立成分：eg.To tell you the truth, I don’t like the way he talked.#2.Voice and Tenses不定式的时态和语态变化1)to do sth. / to be doing sth. / to have done sth.eg. I’m sorry to have kept you waiting so long.When he came in, I happened to be writing a letter.2).语态eg. I have a lot of things to do. / The question is very difficult to answer.#3.不定式的省略：保留to省略do后的动词If you don’t want to do it, you don’t need to.不定式的并列：第二个不定式可省略to。
