(完整版)初中英语⾮谓语动词讲解⾮谓语动词之“动词不定式”详解⾮谓语动词就是不充当谓语的动词,分两种。
⼀是动词不定式。
⼆是动词ing形式。
1)作主语To learn English well is not easy. 或It is not easy to learn English well.[说明]动词不定式作主语时,往往⽤it作形式主语,这种句型可归纳为下⾯的句型:e.g. It is + adj.+ 动词不定式如果要说明不定式表⽰的动作执⾏者,可以⽤for+sb.e.g. It is + adj.+ for sb.to do sth.2)作表语(表语⽤来说明主语的⾝份、性质、品性、特征和状态的,表语常由名词、形容词、副词、介词短语、动词的-ing形式、不定式、从句来充当,它常位于系动词(be, become, appear, seem, look, sound, feel, get, smell等词)之后。
)e.g. My wish is to become a teacher.3)作宾语或者宾语补⾜语e.g. Most of us like to watch football matches.e.g. He told me to be here on time.4)作定语:e.g. I have nothing to say about that thing.5)作状语:e.g. He stopped to have a look.[说明] 动词不定式的否定形式:not + to + 动词原形构成e.g. He asked me not to make such a mistake.2、动词不定式与疑问词连⽤:疑问词who, what, which和疑问副词when, where, how, why等后⾯可以按动词不定式,构成动词不定式短语。
e.g. (1) He doesn’t know how to use the machine.(2) How to use the machine is a question.(3) The question is when to go there.3、省去了to 的动词不定式1)let, have, make+do2)感官动词see, watch, look at, notice, hear, listen to, smell, feel, find +to。
⾮谓语动词⽤法详细讲解⾮谓语动词⽤法详解动词的⾮谓语形式有三种:不定式、动名词和分词(⼀)不定式不定式由“to⼗动词原形”构成,其否定形式是“not to do ” ?不定式可以带宾语或状语构成不定式短语,没有⼈称和数的变化,但有时态和语态的变化?不定式可作主语、宾语、状语、表语和定语,但不能单独作谓语?不定式的逻辑主语有时⽤“for⼗名词或代词宾格”构成.1 ?不定式的⽤法:1)作主语.不定式短语作主语时,往往放在谓语之后,⽤it作形式主语?例如:To see is to believe .It is right to give up smok ing2)作宾语.不定式短语作宾语时,如果还带有宾语补⾜语。
往往把不定式宾语放在宾语补⾜语之后,⽽⽤it作形式宾语.例如:He wan ted to go .I find it interesting to study work with him.3)作宾语补⾜语.例如:He asked me to do the work with him.注意 :在feel,hear,listen to,look at,notice, observe,see,watch,have, let,make等词后的补⾜语中,不定式不带to.但是这些句⼦如果变成被动结构时,就必须带to.例如I ofte n hear him sing the songHe is ofte n heard to sing the song注意:不定式动词在介词but, except, besides后⾯时,如果这些介词之前有⾏为动词do的各种形式,那么,这些介词后的不定式不带to,否则要带to.⼥⼝:She could do nothing but cry.What do you like to do besides swim?I have no choice but to go .动词help之后,带to或不带to都可以。

一、非谓语动词与非谓语动词的区别1.谓语动词在句中可单独作谓语,而非谓语动词不能单独作谓语。
如:Miss Mary teaches us English . 玛丽教我们英语。
(teaches是谓语动词。

(动词用第三人称单数形式)Tom has nothing to do today. 汤姆今天没有什么事要做。
(do用原形)二、非谓语动词的各种形式和应用非谓语动词主要包括不定式、动名词和分词。

解答非谓语动词的题目时,一定要解析句子结构,确定所设空是谓语动词还是非谓语动词,以及非谓语动词在句子中充当的功能(如状语、定语或宾补);找准相关动词的逻辑主语,确定该动词与逻辑主语是什么关系(主动还是被动);搜索句子中相关的时间信息,确定非谓语动词的恰当形式。
1 动名词和不定式作表语①如果表语是不定式,主语也是不定式;表语是动名词,主语也是动名词。
如:To see is to believe.=Seeing is believing.②动名词作主语的句型。

我们初中阶段常见的有:finish, mind, be worth, be busy, practice, have fun, have trouble/problem(in), spend...(in), feel like, be used to(习惯于), give up, keep on, consider, suggest, can't help。
我们可按下面的顺口溜记忆这些词。
完成实践值得忙(finish, practice, be worth, be busy)继续习惯别放弃(keep on, be used to, give up)考虑建议不禁想(consider, suggest, can't help, feel like)喜欢思念要介意(enjoy, miss, mind)(二)动词不定式一、动词不定时的构成不定时的基本形式为:to+动词原形,有时可以不用to,这里的to 是不定式符号,本身无词义,动词不定式的否定形式是not+(to+)动词原形。
非谓语动词的用法总结李靖非谓语动词(不定式、动名词、分词)不是真正意义上的谓语动词,在句中都不能单独作谓语。
但都具有动词的某些特点,可以有自己的宾语或状语,构成非谓语动词短语。
不定式表目的,表将来;动名词表主动,表进行;过去分词表被动,表完成。
一.作主语( 动名词、不定式、过去分词前面加being, 动名词做主语谓语动词用单数)1)不定式、动名词都可做主语,但是动名词做主语多指抽象的概念性的动作,可以是多次的经常的行为;不定式多表示具体的动作,尤其是某一次的动作。
如:Playing with fire is dangerous. 玩火危险。
(泛指玩火)To play with fire will be dangerous. 玩火会发生危险。
2)用动名词做主语的句型:It’s no use/no good/pleasure doing sth 做。
.。
.没有用处/好处/乐趣It’s a waste of time doing sth 做。
.。
浪费时间It is worth doing sth 值得做某事It is no use crying over spilt milk. 覆水难收It is worth making an appointment before you go. 去之前预约一下是值得的。
3)不定式做主语的句型.It is + adj +for sb to do sth.比较:表示人的品质时只能用of sb 如considerate/kind/nice/foolish/stupid/rude/cruel /wise/clever/brave/selfish/crazy/good/careful/careless/impolite/right/wrong等单词出现时。
It is silly of you to say so。
It is important for us to learn English well.It is a must/ a necessity for us to have a good command of the English language.4) “Wh- + to 不定式”可做主语。
