（6）复合不定代词
somebody ,something ,anything, nothing ,everything, everybody等是由some , any ,no ,every, 加上body, thing 构成的,叫做复合不定代词
复合不定代词在句中一般作主语语或宾语。当形容词修饰不定代词时，形容词应该在不定代词的前面。如：Do you notice anything unusual?
另外：不定代词作主语时谓语动词要用单数。eg. Something is in the box.
在反意疑问句中，表示人的不定代词作主语时，其反意疑问句的主语通常要用they或he. 表示物的不定代词作主语时，其反意疑问句的主语通常要用it。
eg. Everybody is here, aren’t they/isn’t he? Everything is OK, isn’t it?
It的用法
1）指上文中提到过的事物 例如：
The book on the desk is not mine. It is Jim’s 2）指不明确的人。例如：
Who is knocking on the door? It may be the postman. 3）代替指示代词this/that 例如：
“What's that？” “It's a color television.” 4）指代时间、天气、气温、距离等。例如：
It's Monday, the 1st of May. It is about a mile to the station. 5)it作形式主语或形式宾语
It is important for us to work hard. It seems that he is quite happy. Do you think it difficult to learn French? I find it easy to surf the Internet.
it作形式宾语： 主+find/think/make it adj. to do sth. 6）常见用it引导的句型
?It's time for sb. to do sth. / It's time for sth.意为\是(某人)该干……的时间了\、\到……的时候了\。例如：
5
It's time for supper ／to have supper. It's time for us to go to school.
?It takes(sb.)some time to do sth.意为\某人)花……时间做某事\。例如： It takes twenty minutes to go to school by bike. It took me a week to finish reading the book.
?It is one's turn to do sth.意为\轮到某人做某事了\。例如： It's your turn to be on duty tomorrow.
④It’s an honor to do sth. “做某事感到荣幸”例如： It’s an honor to work with you.
⑤It is ／ has been ＋时间段＋since ＋一般过去时，意为\自从……以来已过了……(时间)。\例如：
It is / has been four years since he left Fuzhou. It is / has been two weeks since we met last.
⑥It seems ／seemed ＋that从句，意为\看起来好像……\。例如： It seemed that our team was going to win. ⑦It's＋表语＋to do sth.。例如：
It's a good idea to go out for a walk. It’s a good time to climb hills. ⑧It's ＋adj.＋that从句。例如：
It's true that I may fall behind the other students. It’s necessary that everyone obey the traffic rules
⑨It's＋adj.＋of(for)sb.＋to do sth. 对于这个句型究竟用of还是用for，主要取决于前面的形容词。如果形容词是描述不定式行为者的性格、品质等的，如 kind，good，nice，clever等用of；如果形容词仅仅是描述行为的则用for，这类形容词常见的有difficult，easy，hard， important，dangerous等。例如： It is nice of you to come to see me.
It is dangerous for children to play with fire.
it,one, that 作替代词时的区别
?it 指代上文提到的同一对象，是同一事物。可代替不可数名词或单数名词，其复数形式为them. e.g. The weather here is too cold. I don’t like it. (it指代前面提到的the weather)
?one 泛指上文提及的同类事物中的一个，但不是同一事物。one只能代替单数名词，其复数形式是ones. e.g.This bag is too big, would you please show me a smaller one? -- Could you lend me a pen?-- Sorry, I haven’t got one. ?that常用于比较结构句型中，代替前面提到的名词，以避免重复。 e.g. The weather of Beijing is colder than that of Fuzhou. (that在此指代的天气与前面提到的天气为同类。）
