提示注意:
①指人还是指物
②可数还是不可数
③特指还是泛指
④两者还是三者
⑤肯定还是否定

some, any, no和every都可以和one, body, thing连用,构成复合不定代词。
1)复合不定代词作主语时,谓语动词用单数形式。
Something is wrong with the computer.
2)形容词或else修饰不定代词时应该放在不定代词之后。

3)some-/any-复合不定代词的用法与some/any用法基本一致。肯定句以及期待对方肯定回答的疑问句中通用some-;否定句和疑问句句通用any-。
Would you like something to eat?
I don't know anything about it.
I heard somebody singing in the classroom.
4)Each(Neither,Either) None of +名词复数+动词单数

some, any, no和every还可以与where连用,构成表示地点的副词,即:
somewhere 某处,在某处;
anywhere 在任何地方,无论何处;
nowhere 无处,不知名的;
everywhere 到处,处处 = here and there。
注意:else放在不定副词后面。
