二、语法重点 动词不定式 (请大家先认真预习课本123页动词不定式的语法部分)
1. 作主语
动词不定式作主语时，常用it作形式主语，而将真正的主语放到句末。
其结构为：It +be+adj.+（for/of）+动词不定式
例：To speak loudly in public is impolite. 或 It is impolite ____ ________ ________ in public..
It is impolite for us to speak loudly in public.
区分It is adj. for sb. to do sth. 与 It is adj. of sb. to do sth.
for 的意思是“对于”，当要说明动词不定式的动作对于某人是怎么样的，用It is adj. for sb. to do sth.
e.g. It’s difficult for us to finish the work. 译：___________________________________________
如果形容词是kind, nice, right, wrong, good, clever, polite, careful, careless, foolish等描述行为者本身的性格，品质的形容词时，用It is adj. of sb. to do sth.
1.It’s very kind of you to help me. 你帮助我真是太好了。= You are kind to help me.
2. It’s very clever of you to do like that. 译：___________________________________________
3.你那样做很愚蠢。It’s silly _____ ________ _______ ________ that.
2. 作定语
动词不定式作定语要后置。当被修饰的词是它的逻辑宾语时，则动词不定式必须是及物动词。如果不定式动词是不及物动词，就要用必要的介词，使其构成及物的短语动词。
e..g. I have a lot of clothes to wash. 我有很多衣服要洗。
此处逻辑上的动宾结构为wash clothes.
He wants to find a chair to _________ ___________. 他想找把椅子坐。
I need a piece of paper to __________ __________. 我需要一张纸来写字。
此句中sit 为不及物动词，逻辑上的动宾结构为“坐在椅子上”sit on a chair,动词不定式中的介词on不能省。
3. 作状语
1）作目的状语 He ran so fast ________ __________ the first bus. 他跑这么快是为了赶上第一趟车。
2）作结果状语 They were __________ _________ __________ say a word. 他们太激动了，以至说不出话来。
3） 作原因状语 She cried _________ _________the news. 她听到那消息哭了。
观察：观察下列section A 中的句子，划出动词不定式部分并思考它在句中充当什么成分,然后翻译句子。
There are other vehicles for us to choose. 作____语 译：_________________________
Do you know the best way to get there? 作____语 译：__________________________
It’s hard to say. 作____语 译：______________________________________________
You two find out the cost to go by train. 作____语 ___________________________________
Your task is to find out the cost by bus. 作____语______________________________________
I’d love to go by airplane. 作____语 译：_____________________________________
