6、 Janes opinion?四检测反馈 (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 s
7、th.1)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. Its 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.Its very kind of you to help me. 你帮助我真是太好了。= You a
8、re kind to help me. 3.你那样做很愚蠢。Its 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。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。4.勾画出课文中含动词不定式结构的句子并分析出在句子中所担当的成分
