初中英语动词不定式讲解试题和答案
初中英语动词不定式讲解试题和答案一、作主语，可以用it代替，it叫形式主语，动词不定式放在后面叫真正主语1．To learn a foreign language is not easy.It is not easy to learn a foreign language.2. It’s dangerous to drive very fast.二、作表语My idea is to ring him up at once. 我的想法是马上给他打电话。
如果主语部分含实义动词do，且作表语的动词又是“do”的内容，这时表语不定式的“to”可以省略。

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。

初二英语动词不定式用法小结与练习试题
初二英语动词不定式用法小结动词不定式是动词的一种特殊形式,它没有人称和数的变化,在句子中不能做谓语；它由"to+动词原形"构成,其否定形式是"not to+ 动词原形". 在句子中可作主语、表语、宾语、宾语补足语、定语和状语等句子成分。
为使同学们更好地掌握其用法,现总结如下：一、动词不定式作主语动词不定式作主语,例如 T o think of the animals in danger is sad .为避免句子的头重脚轻,常用it作为形式主语,而真正的主语动词不定式后置,如It is sad to think of the animals in danger . 常用句型:It +be+adj./nto do sth./It takes sb. some time to do sth.二、动词不定式作宾语一些动词,如want, decide, hope, ask, agree, choose, learn, plan, need, teach, prepare,等,常接动词不定式作宾语。
应注意有些动词后面可接不定式作宾语,也可接动名词作宾语,但所表达的意义不同。
常见的有：〔1stop to do sth.停下来去做另一件事；stop doing sth. .停止正在做的事〔2try to do sth. 尽力做某事；try doing sth.尝试做某事〔3remember/forget to do sth.记住／忘记去做某事；remember/forget doing sth. 记得／忘记做过某事。
下列动词〔enjoy finish keep mind practice spend advise suggest allow后面不能用不定式,用动名词作宾语三、动词不定式作宾语补足语有些动词,如tell, ask, want, invite, teach, like, call等可接带to的动词不定式作宾语补足语,构成tell/ask/want /call/invite sb. to do sth.结构。

初中英语语法动词不定式讲解动词不定式不定式：to + 动词原形知识梳理：提纲挈领，抓住重点和难点！动词不定式的基本形式是"to + 动词原形"，有时可以不带to。
动词不定式（或不定式短语）没有人称和数的变化，在句子中不能作谓语。
动词不定式仍可保留动词的特点，即可以有自己的宾语和状语。
动词不定式同它的宾语或状语构成不定式短语。
如：to read the newspaper, to speak at the meeting 等动词不定式具有名词、形容词和副词的特征，因此在句子中可以作主语、表语、宾语、宾语补足语、定语和状语：句法作用例句作宾语She wanted to borrowed my radio.They began to read and write.作状语She went to see her grandma lastSunday .He came to give us a talk yesterday.作宾语补足语Lucy asked him to turn off the radio. She asked me to speak more loudly Jim told Ling Feng to go home at once . The father made his son study hard.作定语Have you got anything to say?I had something to eat this morning .作主语To learn a foreign language is noteasy.注：作主语用的动词不定式常常为it替代，动词不定式（或短语）放在后面。
例如： It is not easy to learn a foreign language.It took us three days to do the work.动词不定式的否定形式由"not+动词不定式"构成. 如:Tell him not to be late.The policeman told the boys not to play in the street.Tell him not to be late.The policeman told the boys not to play in the street.4) 不定式省去to的情况: 在感官动词see，watch，look at，hear， listen to，feel 和使役动词make，have，let等所接的宾语中（不定式做宾语不足语），不定式应省去to。
但是在被动语态中不能省。
如：Let me listen to you sing the song.He watched his son play computer games.I saw him run away.------He was seen to run away.The boss make the workers work the whole night.----The workers were made to work the whole night.5) 动词不定式和疑问词连用动词不定式可以和疑问词what ,which, how, where, when 等连用，构成不定式短语。
如：The question is when to start.I don't know where to go .He showed me how to use a computer.What to do is a big problem.例题解析：举一反三，学的更轻松！翻译下列句子，说出句中不定式的作用：1. To grow plants is very important.2.
