高二英语选修七_Unit1_单元语法详解
Unit1 单元语法详解动词不定式一、动词不定式的概念与构成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,在句子中不能作谓语。
不定式的构成:to do (do代表动词原形),其否定形式是not to do,这里的to 是动词不定式符号,本身没有词义(在特殊短语或句式中不定式符号要省略)。
二、动词不定式的时态1-一般说来,不定式的一般式to do表示的动作与谓语动词表示的动作没有时间先后顺序。
如:He seems to know this.他似乎知道了这件事。
I hope to see you again.我希望再次见到你。
2.不定式的进行式to be doing表示的动作通常与谓语动词表不的动作同时进行。
如:Mary seems to be thinking deeply.玛丽似乎在沉思。
I happened to be going that way too.我当时碰巧也在走那条路。
3.不定式的完成式to have done表示的动作发生在谓语动词表不的动作之前。
如:I am sorry to have given you so much trouble.很抱歉给你带来了这么多麻烦。
I am glad to have seen your mother.见到你妈妈我很高兴。
三、动词不定式的用法动词不定式没有人称和数的变化,具有名词、形容词和副词等的功能,在句中可作主语、宾语、表语、定语、状语、补足语等。
1.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 sb.;但如果表语是nice、kind、clever等描述动作执行者的性格、品质等的形容词,则应在不定式前加of sb.常用句型是“It+be+adj./n.(+for/of sb.) +to do sth.”和“It takes/took sb. some time to do sth, 如:It is a great pleasure to talk with跟他交谈是一件高兴的事情。

Grammar
动词不定式 动词不定式由“to+动词原形”构成,
可以在句中作主语、宾语、表语、定 语、状语、补足语等,但不能作谓语。 不定式可以有自己的逻辑主语,即for sb. to do sth. 。
动词不定式的形式:
(1)一般式:to do (2)进行式:to be doing (3)完成式:to have done (4)否定式是在不定式符号to的前面 加not 或never.
2._____(see) is _______ (believe). 3.Don’t forget _______(lock) the door. 4.Please let me _____(help )you. 5.There is nothing _____(worry) about.
6.He hurried to the school,only_______(find)

选修7unit1语法-动词不定式(录课稿)
疑问词+不定式
个别介词可用“疑问词+不定式”作宾语。 The boy has his own idea of how to finish it.
Yao Ming desires to win glory for the country. we have no choice but to wait. I consider it necessary to wear a mask when
going out.
要点归纳
不定式作宾语可以分为两种,即作动词的宾语和作介词的宾语。 如果宾语有自己的补语,则常用it作形式宾语,真正的宾语不定式放到后面。
careful clever
foolish honest
impolite
kind
nice
rude
wise
wrong
e.g. It is clever of him to leave that company. It was wise of your father to make an investment in the AI industry .
3 不定式作宾语 (object)
不定式除了可以作及物动词的宾语,还可以作but, except, besides等介词的宾语。
but/except/besides+ to do sth.
当介词but, except, besides 前面有行为动词do以及其 各种形式时,后面的不定式可以省去to;如果是其他动词,则 to不省略。
带形式主语it的常见句型
