英语中的不定代词有很多，用法也比较灵活，本单元简单介绍常用的几个。

注意：neither通常指代可数名词复数，作主语时，谓语动词用三单形式。
None (of the students) in my class wants / want to give up.
There are more than two students. They don’t want to give up.
none 表示对三者及以上的否定。
注意：当none 指代“可数名词复数”（如 students, books, cars 等）时，谓语动词用单数或复数均正确。
注意：当none 指代“不可数名词”（如 water, money, time, information 等）时，此时主语视为“单数概念”，谓语动词用三单形式。
None (of the water) is left in the bottle.
Water is uncountable.
none 表示对不可数名词的否定。
