语法-动词不定式与一般将来时
英语语法篇之动词不定式动词不定式用法灵活多样;尽管有些动词或短语后面既可以接to do 又可以接doing ,但只要用心观察,发现还是可以找到规律的。
与其说是动词不定式,到还不如说是动词“定式”。
因为我们可以大体上把它分为三类形式,即: do / to do / doing动词不定式没有人称和数的变化,在句中不能独立作谓语,是非谓语形式的一种。
但动词不定式具有名词、形容词和副词特征,在句中可以作主语、宾语、宾语补足语、定语、表语和状语等多种成分。
另外,动词不定式具有动词特点,可以有自己的宾语和状语,组成动词不定式短语。
动词不定式的基本(肯定)形式是to+do,有时可以不带to;其否定形式是not to+do。
1.作主语可以直接作主语。
如:To see is to believe.但在英语中,常用it作形式主语,真正的主语即动词不定式放在后面。
如:It's wrong to play tricks on other people.It's our duty to keep our environment clean and tidy.规律:动词不定式在句中作主语时,常放在It is +adj.(形容词)+to do sth.或It is +n.(名词)+to do sth.句型中,it仅作形式主语。
2.作宾语常可接动词不定式作宾语的动词有:agree(同意), hope(希望), decide(决定), need(需要), mean(打算), wish(希望), fail(失败), want(想要), begin(开始), would like(想要等。
Ask(请求), beg(乞求), leave, like, love, hate(讨厌), prefer(宁愿), order(命令), teach, (教)tell,(告诉)believe(相信), find,(找出)know,(知道)want,(想要)think,(认为)understand,(明白)a.want,decide ,agree等动词后面跟并且只能跟不定式。
不定式的特殊句型too…to…的用法
不定式的特殊句型too…to…的用法以下是小编为大家整理的too…to…的用法总结,希望能帮助大家更好地认识too…to…这个词组,提高英语水平。
一、基本结构特点too…to…结构的基本形式为“too+形容词或副词+to+动词原形”,其意为“太……以至于不能……”。
如:He is too shy to speak to her. 他太害羞,不敢同她讲话。
It’s too cheap to be good. 这东西太便宜,好不了(即便宜无好货)。
He is too young to know right from wrong. 他太小,还分不清是非。
二、不定式的逻辑主语有时不定式前可以带有一个由介词for引出的逻辑主语。
如:It’s too expensive for her to buy. 太贵了,她买不起。
The box is too heavy for the boy to carry. 这个箱子太重,这男孩提不起。
The print is too small for me to read without glasses. 印刷字体太小,我不戴眼镜就看不清。
三、不定式是否带宾语在通常情况下,too…to…结构中的不定式可根据其是否及物来确定它是否带宾语。
如:He is too tired to go any further. 他太累了,不能再往前走了。
(不定式to go不及物,无需带宾语)She is too poor to buy such a nice a dress. 她太穷,买不起那件漂亮的连衣裙。
(不定式to buy后带有宾语 such a nice a dress) 但是,若句子主语与其后不定式有动宾关系,那么,其后的及物动词不定式不能带宾语。
如:The nice dress is too expensive for her to buy. 这件漂亮的连衣裙太贵了,她买不起。
(to buy在此虽为及物动词,但由于句子主语the nice dress与该不定式to buy有动宾关系,故to buy后不宜再接代词it作宾语)注意:若句子主语与其后不定式有动宾关系,且其中的动词为不及物动词,此时应注意在其后加适当的介词。
非谓语动词(non-finite verbs)
在英语中,不做句子谓语,而具有谓语外其他语法功能的动词中,叫“非谓语动词”非谓语动词包括:动词不定式(the Infinitive)动名词(the Gerund)现在分词(the Present Participle)过去分词(the Past Participle)Ⅰ。
动词不定式:动词不定式有两种,带“to”和不带“to(动词原型)”,有人称之为“光秃不定式”,在大多数情况下不定式都带to,动词不定式由“to+动词原型”,这里的to是不定式标志,没有词义,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。
一:1。
不定式做主语:eg : To over come the problem is very difficult不定式做主语,往往用it做形式主语,真正的主语不定式放置句子后面:eg : It‟s so nice to hear your voice.但是,用不定式做主语的句子中还有一个不定式做表语时,不能用it‟s…to…的句型eg : To teach is to learn.比较“it‟s for sb和it‟s of sb1)for sb句型中的形容词一般为表示事物的特征特点,表示客观形式的形容词,如”easy, hard, difficult, impossible”等2)of sb句型中的形容词一般为表示性格,品德,心智能力,表示主观感情或态度的形容词,如”good, kind, nice, clever, foolish”等3)用介词for或者of后面的逻辑主语做句子的主格,用介词前边的形容词做表语,造这个句子,如果通顺用of,不通则用for2.不定式做表语:不定式可放在be动词后面,形成表语eg : My dream is to be a teacher.3.不定式做宾语1)有些及物动词用不定式做宾语,结构为“动词+不定式”P2892)有些动词除了可以用不定式做宾语,还用些不定式做补语,即“动词+宾语+不定式”结构eg : I like to keep everything tidy.I like you to keep everything tidy.3)有些动词或动词词组可以用“动词+疑问词+不定式”的结构:eg : I want to know how to solve the problem.4)如果不定式(宾语)后面有宾语补足语,则用“ it ”做形式宾语,真正的宾语(不定式)后置,放在宾语补足语4.不定式做补语1)有些动词+宾语+不定式P291eg : Father will not allow us to play on the street.2)有些动词+宾语+不定式的结构,不定式的动词往往是be,不定式一般可以省去eg : We believe him (to be) quilty (adj.)我们相信他是有罪的We know him to be fool. (n.) (to be不能省)3)有些动词可以跟”there + to be的结构eg : We didn‟t expect there to be so many people.You wouldn‟t want there to be another war. 你不至于想让另外一场战争发生吧?5.不定式做定语不定式做宾语,通常要放在被修饰的词后,往往表示未发生的动作。
专题09重点语法复习动词不定式作主语和表语
专题09 重点语法复习(动词不定式作主语和表语)动词不定式1. 基础知识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,动词不定式没有人称和数的变化。
一、动词不定式的时态和语态(1) 动词不定式作主语时,一般表示具体的或一次性的动作。
作主语的不定式有时态和语态的变化,且谓语动词通常用单数。
特别注意:很多情况下,作主语的动词不定式都可以用动名词替代,但表示某些具体情况,或表示较强烈的对比,或在某些固定说法中时,通常不用动名词替代。
To know everything is to know nothing. 样样皆通,样样稀松。
(2) 若不定式太长,则往往用it代替不定式作形式主语,不定式移至谓语之后,以使句子结构平衡。
it作形式主语时,有三种情况:①常用形容词作它的表语。
真正的主语不定式通常有逻辑主语,一般用for短语来表示,即for sb. to do sth.(其中sb.就是to do的逻辑主语)。
如:It's important for us to keep the water clean.保持水质清洁对我们来说是很重要的。
特别注意:It+be+adj.+for sb. to do sth.结构中for不能用of来代替,当表语形容词表示主语的性质或特征时,则不用for,而用of(sb.to do sth.)。
如:It's very kind of you to say so.你这样说真是太好了。
(可以说:You are very kind)②有时也接名词作表语。
如:It must be great fun to fly to the moon in a spaceship.乘坐宇宙飞船飞往月球一定很有趣。
③it作形式主语时,还常用于“It takes (took /will take) sb. some time (money) to do sth.”句型中。

不定式具有动词的特征,同时也有名词、形容词和副词的特征。

动词不定式在句中可以作主语、宾语、表语、定语和状语,还可用在复合结构中,而且有完成式、进行式、完成进行式和否定形式。
动词不定式的被动形式除了一般形式外还有其完成式和进行式。

B ,There is nothing to do now. (=We have nothing to do now. ) 现在没事干(强调人)。
There is nothing to be done. (=We can do nothing now. ) 现在没办法了(强调物)。
(1)I have some work to do
I have a letter to be typed.
to do是前面一个名词(常是人)发出的动作;
to be done不是前面名词(人) 发出的动作,是句子外的 其他人发出的动作。
试比较: Have you anything to do this afternoon?
(2)能带宾补的动词还有 consider sth/sb to be(宾补), expect sb to do, tell sb to do, want sb to do, warn sb not to do, wish sb to do, invite sb to do等。
区别 I have some work to do(定语,后讲). (去掉不定式对句义影响不大) The manager get him to finish the task
