动词不定式练习题及讲解
动词不定式用法要点讲解一、作主语动词不定式作主语时，句子的谓语动词常用单数，其位置有以下两种：(1)把不定式置于句首。
如：To get there by bike will take us half an hour.(2)用it作形式主语，把真正的主语不定式置于句后，常用于下列句式中。
如：①It＋be＋名词＋to doIt's our duty to take good care of the old.②It takes sb+some time+to doHow long did it take you to finish the work?③It＋be＋形容词＋for sb＋to doIt is difficult for us to finish writing the composition a quarter of an hour.④It＋be＋形容词＋of sb＋to doIt is stupid of you to write down everything the teacher says.⑤It seems(appears)＋形容词＋to doIt seemed impossible to save money.二、作宾语⒈不定式作宾语①以下动词后，只能跟不定式作宾语。
如：agree,ask,aim,arrange,choose,decide,demand,expect,fail ,help,hope,lean,longmanage,offer,plan,prepare,pretend,promise,refuse,wish等，这些词大部分可接th at引导的从句。
如：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当复合宾语中的宾语是不定式时，先用形式宾语it代替不定式，把不定式置于补语之后，即：主语＋动词＋it＋补语＋to do句式。

动词不定式用法及练习动词不定动式是一种非谓语动词形式，它没有人称和数的变化，在句子中不能作谓语，但可以作除谓语之外的其它任何句子成分（主语、表语、宾语、宾语补足语、定语和状语）；动词不定式具有名词、形容词和副词的特征，同时还保持动词的某些特点，既可以有自己的宾语和状语，动词不定式和它的宾语和状语构成不定式短语。
构成：to do .否定式not to do常见时态：一般时to do 进行时to be doing 完成式to have done完成进行式to have been doing三、动词不定式在句子中的成分1、作句子的主语：现实中常用it作形式主语，而把真正的主语动词不定式（或短语）后置。
比较下列句子To learn from your friends is important.=It is important to learn from your friends . To leave without saying goodbye is impolite.= It is impolite to leave without saying goodbye. To chat with Miss White is a pleasant thing.=It is a pleasant thing to chat with Miss White. To walk to school takes me ten minutes.=It takes me ten minutes to walk to school.句型总结It is + adj. + of sb. to do…= sb. is\are +adj. +to do…在以某些表示人的品质、特征等的形容词（如kind、good、nice、wrong、clever、right等）作表语时，不定式之前常加一个引起的短语，说明不定式指的是谁的情况。
（可以理解为某人的好，坏，聪明，愚蠢，对，错等等）It is very kind of you to help me.It’s not polite of him to speak to old people like that.It is + adj. + for sb. to do…≠ sb. is\are +adj. +to do…如果要说明不定式表示的动作是谁做的，则在不定式前加一个for引起的短语，即不定式的逻辑主语。
It is necessary for us to study hard.It is easy for him to speak English.2、作句子的表语：不定式放在be 动词后面，用作表语如：Her dream is to be a policeman.My job is to help the patient.Your task is to clean the classroom.My dream is to own a robot.The doctor’s suggestion is to take more exercise.The best way is to talk to your parents.His plan is to travel to Beijing this summer.My purpose is to help you solve this problem.3、作句子的宾语：不定式放在及物动词后，用作宾语。
能跟不定式作宾语的动词（及物）很多，常见的有want, like, hate, wish, hope, prefer, try, ask, start, begin, decide, learn, choose, agree, expect, remember, forget, plan, decide, would like, need, choose, agree, promise, refuse, set out, manage, pretend,I want to go home.The workers demanded to get better pay.They began to read and write.She forgot to close the door.He wanted to borrow my CD player.I hope to speak English well.The workers demanded to get better pay.I hope to hear from you soon.John doesn’t want to be the host of the charity show.They are trying to solve the problem by himself.Millions of people have learned to use computers.有些动词既可跟不定式作宾语，也可跟动名词作宾语，但含义不同：forget to do sth.忘记要做某事forget doing sth.忘记曾经做过某事stop to do sth. 停下来去做某事stop doing sth.停止做某事go on to do sth.继续做另一件事go on doing sth.继续做原来在做的事need to do sth.需要做某事need doing sth. 需要被做Don’t forge to turn off the lights before leaving.Father must stop smoking.This bike needs repairing/mending.注意1：动词不定式作宾语时如带有宾语补足语，则要把不定式放在后面，用it作形式主语，构成“主语+动词+it+宾补（形容词、名词）+不定式”结构I found it necessary to talk to him again.I found it important to learn English.I fond it difficult to learn physics.注意2：常用带to的动词不定式作宾语补足语的动词有want, ask, tell, order, get, wish, allow, invite, teach, encourage, beg, 等。
构成“vt,+sb.+(not)to do sth.”结构。
