复合不定代词
由 some, every, no, any分别与 one, thing和 body组合而成的代词, someone, something, somebody； everyone, everything, everybody； no one, nothing, nobody； anyone, anything, anybody
1、由 every构成的不定代词大多具有“复数”的含义,但并不能因此而将其用作复数,因为此类词更强调个体,使用时仍应以单数对待
Eg: Every student is trying their best to achieve high scores in the exam.
2、由 no构成的不定代词表示的是一种否定意义,作主语时,谓语动词多用单数形式
Eg: Nothing is impossible if you put your heart in it.
