初中不定式todo的用法
1. 不定式的用法------1.1 不定式作主语 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。 例如：It's so nice to hear your voice. 听到你的声音真高兴。 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。例如： （对）To teach is to learn. （错）It is to learn to teach. （错）To teach is learning. （错）Teaching is to learn. 典型例题 The chair looks rather hard, but in fact it is very comfortable to ___. A. sit B. sit on C. be seat D. be sat on 答案：B. 如果不定式为不及物动词，其后应有必要的介词。当动词与介词连用时，常位于"形容词+动词不定式"结构的末尾。 1.1.1 不定式做主语It's for sb/It's of sb to do sth 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。
接不定式和动名词含义不同的动词 1. remember(记得)，forget(忘记)，regret(后悔)后接不定式指该不定式所表示的动作还未发生，后接动名词(有时可用完成式)，则指该动名词所表示的动作已经发生。比较。如：Remember to post the letter. 记住把这封信寄了。(“寄信”未发生) I remember posting the letter. 我记得寄了那封信。(“寄信”已发生) He forgot to pay me the money. 他忘记要给我付钱了。(“付钱”未发生) He forgot paying me the money. 他忘记曾给我付过钱。(“付钱”发生了) 2. try 后接不定式表示设法做某事，接动名词表示做某事试试(看有什么效果)。如： I’ll try to come tomorrow. 我明天设法来。 Let’s try knocking at the back door. 咱们敲敲后门试试。 3. mean 后接不定式表示打算(想要)做某事，接动名词表示意味着(要)做某事。如： He means to be a teacher. 他打算当老师。 He did not mean to hurt you. 他不是有意要伤害你。 This illness will mean going to hospital. 得了这种病就意味着要住院。 4. stop 后接动名词表示停止做某事，接不定式表示停下正在做的事去做另一事。如： He stopped speaking, and there was not a sound in the room. 他停止讲话，房里一点声音也没有了。 He stopped to listen, but there was no more sound. 他停下来听，但再也没有听到什么声音。 【注】后接不定式时，不定式不是宾语，而是目的状语。 5. can’t help后接动名词表示禁不住去做某事，接不定式表示不能帮助做某事。如： He couldn’t help crying when he heard the news. 他听到这个消息时禁不住哭了。 The medicine can’t help to get rid of your cold. 这药不能帮你治好感冒。 6. go on 后接不定式表示做完某事后接着做另一事，接动名词表示继续做正在做的事。如： You oughtn’t to go on living this way. 你不应该再这样生活下去了。 Go on to do the other exercises after you have finished this one. 做完这个练习后, 请接着做其他的练习。 【注】也人认为go on doing sth中的doing是现在分词而不是动名词。
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
动词不定式、动名词的用法和区别 动词不定式：动词不定式是由to + 动词原形构成，在句中起名词，形容词和副词的作用，可以担任除谓语以外的其它任何成分。 1. 动词不定式作主语： To mast a language is not an easy thing. / To teach English is my favorite. 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。 It's very kind of you to have given us much help. 2. 动词不定式作宾语： 某些及物动词可以用动词不定式作宾语，这些动词有decide, begin, help, begin, want, wish, like, forget, learn, ask. I like to help others if I can. 3. 动词不定式作宾语补语。 We expect you to be with us. 我们希望你和我们在一起。/ Please ask him to come here quickly.请叫他快过来。 4. 动词不定式作表语： What I should do is to finish the task soon. / The most urgent thing is to find the boy immediately. 5. 动词不定式作定语： There are many ways to solve the problem. / I have something important to tell you. 6. 不定式作状语： We went to the hospital to see our teacher. / She is making a test to get a kind of useful medicine from a Tibet flower. 动词不定式的否定形式：not + to + 动词原形 The teacher told us not to swim in that river. 老师告诉我们不要在那条河里游泳。 It's unfair not to tell us. 没告诉我们真是不公平。 带疑问词的不定式： 疑问词who, what,which,when, where, how, why 可以加在不定式的前面，构成不定式短语，使含义更加具体。Where to go is not known yet. I don't know when to begin.。 Can you tell me where to get the battery. Do you know how to get to the station. 带逻辑主语的不定式： 动词不定式可以带有自己的逻辑主语，构成方法是：for + 逻辑主语+ 不定式。 注意：逻辑主语用宾格形式，for 本身无实际意义，它只表明后面的主语从逻辑上分析是不定式的主语。 It's necessary for us to help each other. / There are much work for me to finish, 动词不定式的被动形式：表示不定式动词同所修饰的名词是被动关系。 He is the man to be examined. 他是受检查的人。/ There are much work to be done. 有好多工作要做。 ●动名词 动名词是由动词原形+ ing 构成，同现在分词形式一样，在句中可作主语，宾语，表语和定语。 1) 动名词作主语： Talking like that is not polite. / Learning from others is important . / Putting on more clothes is not so good . （注：动名词可以象动词不定式一样，用it作形式主语，而把动名词写在后面做真正的主语。）It's no use waiting here, let's go home. / It's very difficult climbing this mountain. 2) 动名词作表语 The nurse's job is looking after the patients. 3)动名词作宾语 有些动词须用动名词来作宾语,它们是begin, mind, suggest, finish, stop, need, enjoy, miss, keep. Please stop smoking in the house. / I like reading in the forest. / Do you mind my opening the windows? 4）动名词作定语 She is studying in the reading room. / He slept in the sleeping bag. （动名词的否定形式：not + 动名词） He pretend not knowing it at all. 他假装全然不知。/ We considered not doing it now. 我们考虑现在不做这件事。 动名词的被动形式：当动名词和它的逻辑主语是被动关系时，用动名词的被动形式来表示。）His being looked down upon made him sick. / I can't really stand being treated like that.

动词不定式和动名词是英语非谓语动词的两个重要部分 一、作主语 1、不定式作主语：动词不定式可直接用作主语, 句子的谓语动词常用单数。 To get there by bike will take us half an hour. 对于主语较长的不定式，可以用it 作形式主语。例如： It's our duty to take good care of the old.How long did it take you to finish the work It is difficult for us to finish writing the composition in a quarter of an hour. It seemed impossible to save money.It's kind of you to help me with my English. 2、动名词作主语：动名词也可直接用作主语，或者用it 作形式主语。例如： Learning without practice is no good.It's no good reading in dim light.It's no use sitting here waiting.It's dangerous swimming in the sea in windy days.There is no saying what will happen next. 3、动词不定式和动名词作主语的区别 (1)不定式作主语经常表示具体动作，或者表示将要进行的动作。而动名词作主语经常表示 抽象的一般性的动作。例如：It's no good for you to eat so much fat. ( 有具体的人for you) It's no good eating too much fat. ( 泛指 ) (2) 不定式的逻辑主语常用 of, for 表示；动名词逻辑主语则常用物主代词、名词、代词表示。例如：It is stupid of you to write down everything the teacher says. (of you) It's no use your pretending that you didn't know the rules. (your) The doctor suggested them having their health check-up once a year. 二、作宾语 1、不定式作宾语 (1) 以下动词后 , 一般只用不定式作宾语 .如 :agree, attempt ， apply， ask, aim, arrange, beg ，choose, decide, demand, expect, fail , help, hope, lean, long, manage, offer, plan, prepare, pretend, promise, refuse, wish afford 等。 I decided to ask for my money back. I decided that I would ask for my money back. When our visit to the farm was over, we expected to start back on foot. When our visit to the farm was over, we expected that we would start back on foot. (2)不定式可先用 it 做形式宾语。 2、动名词作宾语 (1)以下动词后 , 一般只用动名词作宾语 , 如 :admit, appreciate, consider, delay, enjoy, finish, keep, imagine, mind, miss, practise, resist, risk, save, suggest, don't mind, give up, insist, on, put off 等。 I suggest spending our summer vacation in a seaside town. You must give up smoking, for it does too much harm to your health. (2)介词后只能接动名词做宾语 I should go to attend the birthday celebration instead of staying at home. What about inviting Li Jun to make a speech (3)少数特殊结构中只用动名词做宾语。它们可以看作是省略的介词的形式。例如： have difficulty prevent/stop (in) doing sth. have ? (from) doing sth. no trouble (in) doing sth.lose no ti me (in) there is no use (in) doing sth. doing sth. 3、不定式与动名词做宾语的区别 (1)动词后是接不定式还是动名词作宾语，主要是根据使用习惯。有些动词后一般只接不定
