1.>不定代词的用法复合不定代词包括 something, somebody, someone, anything, anybody, anyone, nothing, nobody, no one, everything, everybody, everyone 等。它们在句中可用作主语、宾语或表语，但不能用作定语。something, someone 等和 anything, anyone等的区别与 some 和 any 的区别一样，前者一般用于肯定句，后者一般用于否定句、疑问句或条件句(参见 any & some)。具体使用时应注意以下几点： 1. 复合不定代词受定语修饰时，定语应放在它们后面：
There is nothing wrong with the radio. 这收音机没有毛病。
Have you seen anyone [anybody] famous? 你见过名人吗?
2. 指人的复合不定代词若用作主语，其谓语动词一般用单数，相应的人称代词和物主代词也用单数 he, him, his (不一定指男性)。但在非正式文体中常用复数代词 they, them, their：
Everyone knows this, doesn’t he [don’t they]? 人人都知道这一点，不是吗?
应用型英语
If anybody [anyone] comes, ask him [them] to wait. 要是有人来，让他等着。
3. 指事物的复合不定代词若用作主语，谓语动词只能用单数，相应的人称代词也只能用话语标记 it，而不用 they：
Everything is ready, isn’t it? 一切都准备好了，是吗?
4. anyone, everyone 等只能指人，不能指物，且其后一般不接of 短语。若是指物或后接 of 短语，可用 any one, every one (分开写)：
