1. some 和 any:
单数:somebody, someone
复数:somebody, some people, someones
2. each 和 every:
单数:each person, every person
复数:each of them, every one of them
3. either 和 neither:
单数:either of them, neither of them
复数:either of them, neither of them(这两个词通常不用于复数形式)
4. both:
单数:both of them
复数:both of them(这个代词通常不用于复数形式)
5. many 和 few:
单数:many people, few people
复数:many people, few people
6. much 和 little:
单数:much food, little food
复数:much food, little food
7. all:
单数:all of them
复数:all of them
8. most:
单数:most of them
复数:most of them
9. some 和 any(在否定句中):

复数:somebody, some people, someones
10. other:

记住,有些不定代词(如“either”和“neither”)通常不用于复数形式。在具体使用时,根据句子的上下文和逻辑关系来确定单复数形式。
