牛津上海版8A语法动词不定时讲解及练习(有答案)

语法：动词不定式动词不定式是一种非谓语动词，其结构为“(to) + 动词原形”。

动词不定式的用法:1. 作宾语不定式常用作某些动词的宾语, 如want, hope, wish, agree, learn, like, love, offer(表示要)，plan, promise, remember, forget, try(努力), decide(决定), begin, start等。

例如：She wanted to buy a few postcards. 她想买几张明信片。

The car repairer began to check my car. 汽车修理工开始检查我的汽车。

It started to snow at midnight. 半夜里开始下雪了。

在某些动词如know, learn, decide, wonder(想知道)，remember, forget, tell, show, teach等后，还可以接“疑问词+ to不定式”。

例如：I didn’t know what to say to him. 我不知道对他说什么好。

They are learning how to use the computer. 他们正在学习怎样使用电脑。

Did they tell you where to go? 他们告诉你去哪儿吗？The farmer showed us how to cut rice. 农民教我们怎样割稻。

初中英语动词不定式用法梳理及练习题含答案

初中英语动词不定式用法动词不定式是由“不定式符号to+动词原形”构成的一种非谓语动词结构。

有些动词不定式不带to，动词不定式可以作句子的主语、表语、宾语、定语、补语、状语或单独使用。

不定式保留动词的某些特性，可以有自己的宾语、状语等。

动词不定式和它后面的宾语、状语等一起构成短语，叫作不定式短语。

一、用作主语直接把动词不定式置于句首的情况不多，多数情况用it 作形式主语，把真正的主语——动词不定式置于句末，特别是不定式短语较长时。

动词不定式作主语，谓语动词用第三人称单数形式。

带疑问词的不定式短语作主语常置于句首，复合不定式结构作主语常置于句末。

如：1. I t is our duty to try our best to deal with these problems.2.The head teacher said it was necessary to talk with his mother.3.How to learn English well is important.4.T o see is to believe.(眼见为实；百闻不如一见)二、用作表语动词不定式作表语，常说明主语的内容、性质、特征。

如：1.T he best way is to join an English club.2.T he first thing is to listen to the teacher carefully.三、用作宾语1.可以接带to 的动词不定式作宾语的动词主要有：要求选择同意(ask, choose, agree) ，期望决定学习(expect, hope, decide, learn) ，宁可假装知道(prefer, pretend, know)，希望想要愿意(wish, want, would like / love)。

如：1)We decided to talk to some students about why they go there.2)He prefers to eat white bread and rice.3)Id love to visit Mexico.2.动词decide, know, learn, show, teach, tell...，介词结构on...可用疑问词带to 的不定式短语作宾语，但why 后面的不定式不带to。

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。

动词不定式讲解、专项练习及答案

初中英语语法（动词不定式）1．不定式的基本形式与结构动词不定式指通常由to加上动词原形(如to write) 所构成的一种非限定性动词形式，但在有些情况下to可以省略。

动词不定式有进行体和完成体(如上to be writing，to have written)，也有被动态(如to be written)，所有的主动词，不论是及物动词还是不及物动词，也不论是动作动词还是状态动词，都有不定式形式。

助动词除be和have外，没有不定式形式。

动词不定式在语法功能上可作主语、宾语、表语、定语和状语。

2．不定式的用法1)不定式结构作主语1.Te get contact with his family in Taiwan made him extremely happy since they separated more than 40 years ago．2.To finish that task in such a short time is really a challenge．在上述情况下，如果不定式较长，显得头重脚轻，则可由代词让作形式主语(形式主语it不可由that或this等其他代词代替)，而将不定式放到后面。

如：1.It made him extremely happy to get contact with his family in Taiwan since they separated more than 40 years ago．2.John admitted that it is always difficult for him to be on time．不定式结构所表示的动作是谁做的，即不定式的逻辑主语，通常可以通过for sb. to do sth. 结构表达：1.It is quite important for us to read good books during a general review．2.It is not difficult fot those talented students to pass the exam.在某些形容词(如careless，clever，considerate，foolish，good，impolite，kind，naughty，nice，silly，stupid等)作表语时，不定式后可以加of来引导出其逻辑主语：1.It is very kind of you to tell me the truth．2.It is stupid of him to do such a silly thing．2)不定式作宾语不定式作宾语有两种：一种是及物动词后直接跟带to的不定式，另一种是“及物动词+疑问词+带to的不定式。
