用单数还是复数要视情况而定。
常用不定代词有:some(something,somebody,someone,somewhere),(anything,anybody,anyone,anywhere), no(nothing,nobody,no one),
every(everything,everybody,everyone,everywhere),all,each,both,much,many,(a)little,(a)few,other(s),another,none,one,either, neither等。
扩展资料:
1、如果主语是some(something,somebody,someone,somewhere),any(anything,anybody,anyone,anywhere), no(nothing,nobody,no one),
every(everything,everybody,everyone,everywhere),each,a (little), another,none,one,either 等时,谓语动词用单数形式。
2、如果主语是all,both, all, others 等时谓语动词用复数。
