高中英语动词不定式用法大全(名师总结必考语法知识点，值得下载) 英语动词的非谓语形式为三种：动词不定式、动名词和分词。非谓语动词没有人称和数的变化。 动词不定式是一种非谓语动词形式，其结构为“to＋动词原形”，其中to 不是介词，而是动词不定式的符号，称为小品词，动词不定式没有人称和数的变化。动词不定式和其后面的名词等构成不定式短语，在句子中可以用作主语、表语、宾语、补足语、定语、状语等。 一. 作主语例如： To be a doctor is hard. 做医生很难。 To learn English well is not easy. 学好英语不容易。 To say is to believe.眼见为实。 动词不定式（短语）作主语时，为了避免句子的头重脚轻，可以用“it”作形式主语，而把真正的主语－－动词不定式（短语）放在句子的后部。例如上面的句子可以表示为： It is hard to be a doctor. It is not easy to learn English well. 再如： It’s important to pla nt trees in spring. 如果动词不定式的动作是谁做的，可以在动词不定式前面加一个由介
词for引导的短语，称为不定式的复合结构。例： It’s good for us to read English aloud in the morning. 对我们来说每天早晨大声读英语是很有益的。 It is important for students to use English every day. 对学生来说每天使用英语是很重要的。 二. 作表语：（在形式上，位于系动词后的就是表语。从含义上讲，表语是回答主语“是什么”或“怎么样”的语法成分。） 动词不定式（短语）作表语常用于系词be的后面。例： His work is to drive a car. 他的工作是开车。 My job is to feed animals. 我的工作是饲养动物。 Her ambition is to be a doctor. 她的理想是当医生。 三. 作宾语 动词不定式（短语）可以放在一些动词后面用作宾语，能以动词不定式作宾语的动词有：begin, start, want, forget, remember, show, learn, like, hate, love, ask等。例： I want to tell you a story. 我想给你讲个故事。 They begin to work at eight every morning. 他们每天早晨8点开始工作。 Don’t forget to lock the door.别忘了锁门。 Would you like to go and have a picnic with us tomorrow?明天和我们一

不定式什么时候不带to
动词不定式何时不带to? 在英语中，常见的不定式是带to的不定式，但在某些情况下，要使用不带to的不定式。关于这类不带to的不定式，在使用时极易出错，因此，只有经常注意分析此类语言现象，才能达到正确理解的目的。现将不带to的不定式的几种情况列举如下： 一、在“动词＋宾语＋不定式”结构中，如果动词是表示感官意义的，如see，feel，hear，observe，notice，watch， listen to，look at等等，其后作宾语补足语的动词不定式结构不带to。例如： Did you see him go into the house？你看到他进入那座房子了吗？ She looked at（watched）other people play basketball．她在观看别人打篮球。 I didn't notice anyone enter the room．我没注意到有人进入那房间。 He listened to us talk．他听我们谈话。 二、在使役动词make，let，have等之后，作宾语补足语的不定式结构不带to。例如： John made her tell him everything．约翰叫她把一切事情都告诉他。 The soldier had him stand with his back to his father．士兵要他背对他父亲站着。 Let me do it．让我来做。 注意：当这类动词转换为被动语态时，后面不带to的动词不定式要转换为带to的动词不定式（但have一般不用于被动句）。但当句子的动词为let时，to仍可省略。例如： The boy was seen to go into the house．有人看到那男孩走进那座房子。 They were made to work day and night．他们被迫日夜干活。 The prisoners were let go．罪犯被释放了。 三、在help后面可以接带to或不带to的不定式。例如： Can I help（to）carry it for you？我可以帮你拿这个吗？ They helped（to）carry the boxes upstairs．他们帮忙把箱子搬上楼去。 四、当介词except，but后接不定式时，如果except，but前面含行为动词do或do的各种词形时，不定式一般不带 to。例如： There was nothing to do but wait till he came back．没有办法只好等他回来。 He will do anything except lend you money．他决不会借钱给你。 如果except，but前面没有do这一动词或do的各种词形时，不定式一般都带to。例如： There's no choice but to wait for the rain to stop．没有别的选择，只好等雨停下来。 五、在“Why．．．？”或“Why not．．．？”结构中，紧接其后的动词不定式总是不带to。例如：
动词不定式的基本用法

不带to的动词不定式讲课教案
不带to的动词不定式有哪些 不定式是英语动词的非限定形式之一，是英语中一种非常活跃的语言现象，不带to的不定式（bare infinitive）是我们学习、掌握和运用这一语法现象的难点。本文的目的就是要对不带to的不定式作一粗浅的探讨。首先要指出的是，不带to的不定式的使用实际上非常普遍，主要用在情态动词和助动词will，shall，would，should，can，could，may，might，must…以及在作为情态动词的need和dare之后。但因为这一点在学习英语的过程中极易掌握，故不在此赘述。除此以外，在下列情况下也要使用不带to的动词不定式。 1．在see，feel，hear，watch，observe，listen to，look at, notice等感官动词或短语以及let，have，make等表示祈使意义的动词后面；不定式作宾语补足语不能带to；help后面的不定式可以不带to，也可以保留to；know在一定的条件下，后面的不定式作宾语补足语时可以不带to。例如： I saw the man come out of the house． I heard her say that she was from Japan． We felt the house shake． They watched the sun sink into the sea． Did you notice him stop？ They did not observe Jim come in and go upstairs． She was listening to him climb the stairs． Look at the boy run！ I'll let you know as soon as I hear from her． I had him mend my watch． Electricity makes motors run． He helped me（to）plant trees． I have never known him sing so beautifully． 不带to的动词不定式跟在上述动词后面时，情况比较复杂，有以下几个问题须特别注意： （1）当上述句子变成被动语态时，原来作宾语补足语的不定式则相应地成为主语补足语。这时，不定式就一定要带to，以上述句子为例：
非谓语动词之动词不定式(todo)的用法
非谓语动词之动词不定式（to do）的用法 非谓语动词是指在句子中不是谓语的动词，主要形式有：不定式、动名词和分词（现在分词和过去分词）。 “to do”动词不定式的变形 动词不定式的用法 充当主语（一般会用it 当形式主语） To swim here is dangerous. = It is dangerous to swim here. To pass this English exam is unlikely. = 充当表语（多数情况下，可以转换成动词不定式做主语） My job is to help with your English learning. To help with your English learning is my job. 充当宾语（只能做某些动词的宾语，一般不做介词的宾语；有时用“it”做形式宾语） I decided to attend this meeting last night. I find it necessary to learn a foreign language. 注意：当以下动词欲接动词作宾语时，只能跟不定式作宾语。 decide, determine, learn, wish, hope agree, plan, pretend, dare, refuse, fail prepare, try, manage, help, promise offer, beg, demand, afford, arrange, be supposed
充当宾语补足语 I persuaded him to make a speech in public. 注意：在感官动词／使役动词／help后（see, hear, watch, notice, make, have, let后不定式做宾补时，可省略“to”） I saw them have a disagreement on who should sweep the floor. （我看到了他们争论的整个过程） 但，感官动词后面也可接Ving形式，表示正在进行。 I saw them arguing about who should sweep the floor. （我看到他们正在争论谁该扫地，并不一定看到了整个过程） 充当状语（目的，原因，结果状语，其逻辑主语与句子主语一致） I wrote him a letter to further explain this matter. （目的状语） I’m sorry to bother you.（原因状语） He queued for hours at the box office only to find that the show was sold out. （结果状语，only + to find/realize/discover表示出乎意料的结果） 充当定语（不定式作定语，要放在所修饰的词的后面） I have a lot of dishes to wash. Do you have anything to say There are 3 questions to answer. 一些固定句型中不定式省略“to” had better would rather do… than do… why not do “except/but” 有“do” 无“to”，有”to”无“do” have nothing to do but do… do everything but/except have no choice but to want nothing but/except to 当两个或多个作用相同的不定式并列（and/or/than）时，通常只保留第一个不定式的“to”.

高中英语《英语动词不定式》
英语动词不定式 对于英语来说接不定式的单词多为“打算”“计划”“希望”“将要做某事”等表示未来的动词。同样与不定式表示不同的动词不定式表示正在进行，一般性或经常发生性的行为。 定义 （语态）动词和参与此动作的主语之间关系的一个术语。当主语是动作的发起者（或之一）时，称为主动语态； 如果动词不定式的逻辑主语是这个不定式所表示的动作的承受者，不定式一般要用被动语态形式。如： It's a great honour to be invited to Mary's birthday party.（不定式作主语是被动语态to be invited是被邀请） It was impossible for lost time to be made up.（不定式作主语） I wish to be sent to work in the country.（不定式作宾语） Can you tell me which is the car to be repaired?（不定式作定语） He went to the hospital to be examined.（不定式作状语） My work is to clean the room every day.（不定式作表语） 在There be结构中，修饰主语的不定式可用被动，也可用主动。如：There are still many things to take care of (to be taken care of).但有时两种形式表达的意思不同，如：There is nothing to do now.( We have nothing to do now.) There is nothing to be done now.(We can do nothing now.) 形式 1) 现在式：一般现在时表示的动词，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。一般为：动词+ to do something He seems to know this. I hope to see you again. = I hope that I'll see you again.我希望再见到你。 2) 完成式：表示的动作发生在谓语动词表示的动作之前。 I'm sorry to have given you so much trouble.
