文档介绍：复合不定代词的用法
复合不定代词的用法：
由some, any, every, no, 加thing, body, one构成的词叫不定代词，它们共有12个(其中no one 例外)，即：something, anything,具有单数的含义，因此通常被看成是单数第三人称。当它们充当句子的主语时，其后的谓语动词用单数形式。
如：
Is everyone here today? 今天，大家都到齐了吗?
Nothing is difficult if you put your heart into it.
世上无难事，只怕有心人。
Nobody/No one knows his name
There is something or somebody near us.（作主语）
2. 因为some一般用于肯定句，any一般用于否定句或疑问句，no表示完全否定，因此由some, any, no与-one,-body组成的复合代词的用法也一样。somebody，someone，something一般用于肯定句，而anybody，anyone，anything一般用于否定句、疑问句或条件句。
--Did you buy anything special?
--Yes, I bought something for my father.
--No, I didn’t buy anything. (I bought nothing)
Someone is singing in the next room.
Does anyone live in the old house?
Did you go out with anyone ?
No one knows his name.
Would you like something to eat？
表示邀请时，疑问句里可用something．
3. 第二部分为-one和-body的复合代词只能用于表示人，它们的形式是单数形式，相应的人称代词和物主代词用单数 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来避免由于 如：
Everyone knows this, doesn’t he [don’t they]?
There is someone in your office. Can you hear them talking?them指代someone
4. 第二部分为-thing的复合代词只能用于指物。相应的人称代词也只能用 it，而不用 they。 如：
There was something wrong with the car so he had to stopped it.
Everything is ready, isn’t it?
一切都准备好了，是吗?
5. 形容词修饰这些复合不定代词，形容词必须后置。如：
There is someth
