高一英语 模块4 动词不定式讲解和练习题 教案 外研版必修3
动词不定式是由“to+动词原形〞构成 (有时可以不带to)。
其否定形式是“not+动词不定式〞(not不与助动词连用)。
它属于一种非谓语动词的形式，在句子中不能充当谓语，没有人称和数的变化，但它可以保留动词的性质，其本身可以带宾语或状语等附加成分〔不定式和其附加成分称为不定式短语〕。
动词不定式〔短语〕的句法功能非常广泛，在句中可作主语、宾语、补足语、表语、定语及状语等成分。
一、作主语〔1〕动词不定式作主语时，谓语动词常常用单数。
例如：To do morning exercises is useful for our health. 做早操有利于我们的健康。
To sweep the floor is my duty every day. 每天打扫地板是我的责任。
〔2〕如果动词不定式太长，常常用 it 作形式主语，而将真正的主语——动词不定式后置。
例如：It took me half an hour to walk there．我走到那儿花了半小时的时间。
It’s important for us to learn English well．对我们来说，学好英语是重要的。
二、作宾语〔1〕能够接动词不定式作宾语的有〔固定结构〕 ask, agree, beg, decide, determine, fail, hope, manage, offer, plan, prepare, pretend, promise, refuse, wish 及 would like/love 等动词，但 finish, enjoy, miss, appreciate, mind, advise, suggest 等动词后面通常只能接动名词作宾语。
例如：I hope to visit this place again. 我希望能再度访问此地。
She enjoys reading very much．她非常喜欢读书。
The driver failed to see the other car in time. 司机没能及时看见另一辆车。

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。
动词不定式用法全解(含测试题及答案)
动词不定式用法全解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。
动词不定式的形式：第一部分动词不定式的时态一、动词不定式的时态：动词不定式不能在句中作谓语，尽管它本身有时态的变化，但是却不能靠自身的变化形式表示动作发生的具体时间。
动词不定式发生的时间，一般只能根据谓语动词的时间，产生相对的先后时间关系。
1．不定式的一般式，表示不定式的动作与谓语动词动作几乎同时发生，或在谓语动作之后发生，或者不强调不定式动作的时间性。
但不定式表原因时，往往先于谓语动作之前发生。
如：The news will not fail to surprise him.这个消息将不会不使他大吃一惊的。
（不定式动作在将来和谓语动作同时发生）I helped to repair the car.我帮助修理汽车。
（不定式动作在过去与谓语动作同时发生）He didn't know where to go.他不知道该去哪儿。
（不定式稍晚于谓语动作）Tell your brother not to come tomorrow.告诉你哥哥明天不要来。
（不定式晚于谓语动作）判断：He decided to sell his car.I tried to go to school in time.I hope to see you soon不定式表示谓语动作的原因时，往往发生在谓语动作之前。
如：I am very happy to see you here.She seemed surprised to meet us.（先是遇见我们，她然后很吃惊）2．不定式的完成式，通常表示动作发生在谓语动词之前。
高中英语牛津上海版高中一年级第一学期动词不定式讲解及练习(有答案)
高一动词不定式讲解及练习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。
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。
（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.（3）作宾语：(1)不定式作宾语时常直接放在谓语动词之后。
