选修7unit1语法-------动词不定式用法精讲精练

动词不定式用法精讲精练【考题引路】例1.The ability an idea is as important as the idea itself （2011湖南）A expressingB expressedC to expressD to be expressed【解析】句意为“想法重要，提出想法的能力也同样重要。

”express 修饰的是ability, 为主动关系，排除B和D表示被动的选项；ability作为一个抽象名词，通常使用动词不定式做定语，联系到短语be able to do sth，不难推断正确选项为C。

例2.Twenty students want to attend the class that aims to teach to read fast.（2011辽宁）A. what B. who C. how D. why【解析】考查疑问副词+ to do的用法。

句意为“有二十名学生想听旨在提高阅读速度的课程。

”fast提示了方式，how + to read fast等同于名词，作teach的宾语。

故选C。

例3.Thai is the only way we can imagine the overuse of water in students’ bathrooms. （2010上海）A. reducing B. to reduce C. reduced D. reduce【解析】此处应该用不定式the way to do sth表示做……的途径、方式。

the only way to do…,we can imagine 做定语, 前面省略了that.故选B。

例4.There were many talented actors out there just waiting ______.（2010江西）A to discoverB to be discoveredC discoveredD being discovered【解析】演员等待被发现, 用被动, 发现发生在等待之后, 所以用不定式. B。

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。
