1.复合不定代词或副词的构成及用法
构成：由some, any, no, every分别加上-body, -thing, -one构成的不定代词叫做合成不定代词；加上-where构成副词。
用法：
（1）不定代词作主语时，谓语动词要用单数。
There is nothing wrong with the TV. Everybody likes reading.
（2）some-不定代词，通常用于肯定句中；
any-不定代词则多用于否定句、疑问句中。
但some-可用于表请求、邀请、预料对方会作肯定回答时的疑问句中。
Someone is calling me. There isn’t anyone else there.
Is anybody over there? Could you give me something to eat?
（3）形容词修饰不定代词时要后置。
There is something delicious on the table.
