人教版英语八年级上册动词不定式讲解,专项练习(附答案)
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。

八年级英语动词不定式+双宾语讲解及练习
八年级英语动词不定式+双宾语讲解及练习专题三:动词不定式+双宾语一.动词不定式含义当我们要表示“想做某事、需要做某事或决定做某事”时,就会出现两个动词连用的情况,这时应如何表达呢?同学们自然会想到want to do sth。
need to do sth.和decide to do sth.等表达方式。
行为动词后的动词都采用了“to+动词原形”的结构。
我们把这种结构称为动词不定式。
动词不定式没有人称和数的变化,在句中不能作谓语。
二.动词不定式的功能1.动词不定式作宾语(1)动词+to do sth.表示的多为将来的行为。
如:want to do sth。
/ hope to do sth。
/ learn to do sth。
/ try to do sth。
/ decide to do sth。
/ forget to doXXX to do sth。
/ stop to do sth./ plan to do sth.等(2)to偶然可省略,布局为动词+do sth.had better do sth。
/ why not do sth.2.动词不定式作宾语补足语(1)宾语补足语是对宾语的补充说明,结构:“动词+宾语+动词不定式”。
其否定结构要在todo前面加not,构成not to do。
如:allow sb。
to do sth。
/ choose sb。
to do sth。
/ want sb。
to do sth。
/ tell sb。
to do sth。
/ ask sb。
to doXXX(2)在表示感觉、祈使等意义的动词help。
make。
let。
have。
feel。
see等后接不带to的不定式。
3.动词不定式作目的状语(1)假如透露表现“做某事是为了甚么”,能够用动词不定式透露表现目标,常与soas,in order等组成短语不定式既可以放在句首,也可以放在句尾。
如:XXX to have rest.=To have rest。

八年级英语动词不定式用法单选题40题1. In our school, ______ is a good way to show our love for the environment.A. plant treesB. planted treesC. to plant treesD. planting trees答案:C。
解析:在这个句子中,动词不定式“to plant trees”作句子的主语,表示一种具体的行为动作,即“种树是一种展示我们对环境热爱的好方式”。
选项A“plant trees”是动词原形短语,不能直接作主语;选项B“planted trees”是过去分词短语,不能作主语表示主动的动作;选项D“planting trees”是动名词短语,虽然动名词也可以作主语,但这里根据题意,强调具体的一次性的动作,用动词不定式更合适。
2. ______ early in the morning helps us keep healthy.A. Get upB. Got upC. To get upD. Getting up答案:C。
解析:“To get up”作为动词不定式在句中作主语,表示“早上早起有助于我们保持健康”这个动作概念。
选项A“Get up”是动词原形,不能作主语;选项B“Got up”是过去式,不能作主语;选项D“Getting up”是动名词,动名词作主语表示一般性、习惯性的动作,而这里强调具体的早起这个动作,用动词不定式更符合语境。
3. For students in our school, ______ a part - time job can teach us a lot.A. haveB. hadC. to haveD. having答案:C。
解析:“to have”为动词不定式,在句中作主语,表示“对于我们学校的学生来说,做一份兼职工作能教会我们很多东西”。
选项A“have”是动词原形,不能作主语;选项B“had”是过去式,不能作主语;选项D“having”是动名词,动名词作主语强调一般性的行为,这里表示具体去做一份兼职的动作,用动词不定式更恰当。
人教版英语八年级上Unit 5动词不定式
动词不定式一、结构:动词不定式分为带to不定式(to do sth.)与不带to 不定式(do sth.)。
其中,to 不是介词,而是动词不定式符号,无意义,可以不翻译。
肯定式:to do 否定式:not to do二、作用:在句子中可以作主语、宾语、表语、宾语补足语、定语或状语等。
三、用法:1、作主语不定式作主语时,谓语用单数(如并列时则用复数)。
往往用it作形式主语,把不定式放在谓语后面。
常用结构为:It is + adj. /n.(+ for sb.) + to do sth.It is + adj./n. + (of sb. )+ to do sth.e.g. To watch movies is my hobby.To fight with crime is dangerous.It’s enjoyable for me to have dinner with you.It’s necessary to learn every subject well.It’s kind of you to che ck the information carefully.2、作宾语(1)动词+不定式:v.+ to do sth.下列动词(短语)通常用不定式作宾语:help(带to不定式或不带to 不定式皆可), need, want, hope, wish, expect, learn, decide, choose, would like, like, love, begin, start, stop, try, forget, remember等。
e.g. He decided to go on a vacation.James chose to work in the city.Teachers teach to learn something.(2)动词(know, ask, show, teach, find out等)+疑问词+不定式: v. + wh- /how+ to do sth。

第08讲动词不定式掌握动词不定式构成及用法。
【典例】考点1:动词不定式作主语1.It’s important for us________a balanced diet which can help us keep fit.A.not to have B.not having C.to have D.having【答案】C【详解】句意:对我们来说,有一个平衡的饮食是很重要的,它可以帮助我们保持健康。
考查非谓语动词。
It is+形容词+for sb to do sth“对某人来说做某事是……的”,为it固定句型,故选C。
2.The elephant was too big.It was hard for people________it.A.weigh B.weight C.to weigh D.weighing【答案】C【详解】句意:大象太大了。
人们很难称它的重量。
考查非谓语动词。
weigh动词,“称重量”;to weigh不定式形式;weighing现在分词形式;weight名词,“体重”;根据“It was hard for people...”可知考查“It is+形容词for sb.to do sth.”,故选C。
考点2:动词不定式作宾语1.—I’m sorry,Miss Green.I left my math book at home.—It doesn’t matter.Please don’t forget________it here tomorrow.A.taking B.to take C.bringing D.to bring【答案】D【详解】句意:——格林老师,我很抱歉。
我把数学书落在家里了。
——没关系。
请别忘了明天把它带来。
考查非谓语动词和动词辨析。
bring带来;take拿走。
根据语境可知老师让学生把家里的书明天带来,应用bring,排除AB选项;forget to do sth忘记做某事(未做),forget doing sth 忘记做某事(已做)。
八年级英语动词不定式用法梳理
八年级英语动词不定式用法梳理动词不定式是由“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.To 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.The best way is to join an English club.2.The 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。

语
一)动词不定式
1、什么是动词不定式
动词不定式由to+动词原形构成。
这里的to是不定式标志,没有词义。
不定式的否定结构是在动词不定式前直接加not。
不定式具有名词、形容词或副词的某些语法功能,又有动词的时态和语态的特点及作用。
常见的形式如表所示(以及物动词do为例),不及物动词没有被动语态。
主动语态被动语态
一般式 to do to be done
进行式 to be doing
完成式 to have done to have been done
完成进行式 to have been doing
2、不定式功能及常见不定式
第一类:动词+不定式
语法分析:有些及物动词后面可以用不定式表示动作的对象,这时不定式相当于名词或代词,做及物动词的宾语。
1) want to do sth. 想做某事
①Do you want to watch a game show?
