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。
