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能够省略。

动词不定式有实行体和完成体(如上to be writing,to have written),也有被动态(如to be written),所有的主动词,不管是及物动词还是不及物动词,也不管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,假如不定式较长,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,通常能够通过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,不定式后能够加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。

中考英语非谓语动词用法系列讲座---动词不定式、动名词及动词过去分词精讲及练习

中考英语非谓语动词用法系列讲座---动词不定式、动名词及动词过去分词精讲及练习非谓语动词主要指在句中不能充当句子谓语,而是充当句子其它成分的动词。

非谓语动词有三种形式:动词不定式、动名词和分词(包括现在分词和过去分词)。

现在分词和动名词又统称为动词v--ing形式。

非谓语动词没有人称和数的变化,但有语态和时态的变化。

本讲座主要对非谓语动词的基本用法分别进行系列讲解。

第一讲:动词不定式用法精讲及练习考点一:动词不定式的基本用法动词不定式由“to+动词原形”构成,在某些情况下,to可以省略。

动词不定式在句中主要起名词、形容词、副词的作用,因此,动词不定式可以作句子主语、宾语、表语、宾语补足语、定语、状语、同位语和独立结构。

但在初中阶段,主要掌握动词不定式作句子的主语、宾语、表语、宾语补足语、定语、状语为主。

为了简明扼要地掌握动词不定式的用法,我们以表格的形式呈现给大家。

见下表:表(一):动词不定式的基本形式:【典型考例】(2019湖北襄阳)我们的老师总是告诉我们,在学习中不要逃避任何困难。

(keep)Our teacher always tells us___ _ in the study【析】正确答案:not to escape any difficulties。

“告诉某人不要做某事”在英语中为tell sb. not to do sth.,not to do sth为动词不定式的否定形式,作动词tell的宾语补足语。

“逃避任何困难”为escape any difficulties。

【典型考例】(2019哈尔滨)Kids like reading stories which can make them _____.ughB.to laughughing【析】正确答案:A。

句意是:孩子们喜欢那些能让他们哈哈大笑的故事。

动词make为使役动词,其后接不定式短语作宾语补足语时,省略to。

即make sb do sth“使某人作某事”,故正确答案为A。

初中初中英语动词不定式的用法

初中初中英语动词不定式的用法

初中初中英语动词不定式的用法篇一:初中动词不定式用法讲解初中动词不定式用法讲解动词不定式是动词的一种非谓语形式,又叫非谓语动词,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,这里的to是动词不定式符号,本身没有词义,其否定形式常在to前加not;由于它仍保持动词的特点,可以有自己的宾语和状语,还可以带疑问词和由for引出其逻辑主语等形成动词不定式短语;不定式或不定式短语具有名词、形容词和副词的特征,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时,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。

如要说明动作的执行者,可在不定式前加for引导的短语;但如果表语是nice, kind, clever等描述动作执行者的性格、品质的形容词时,则应在不定式前加of引导的短语。

常用句型: 1,It +be+adj./n.+(for/of sb.) to do sth.(用of还是for决定于前面的adj, adj若是指sb.的特性,就用of,adj若是指sth的特性就用for)例句:It’s so nice of you to help me with my homework.你真是太好了,帮助我完成作业。

It’s very difficult for me to do the math homework.数学作业对于我来讲太难了。

2,It takes sb. some time to do sth.例句:It takes my mother all day to do the housework.做家务花了我妈妈一整天的时间。

二、动词不定式作宾语一些动词,如want, decide, hope, ask, offer, agree, choose, learn, plan, need, teach,prepare等,常接动词不定式作宾语(如want/decide to do sth.等)。

同时动词不定式又具有名词、形容词、副词的特征,在句中可以作主语、表语、宾语、宾语补足语、定语和状语。

二. 动词不定式的构成:to+动词原形
