就该是：some.some.the others 是固定用法
例如：There're so many children on the playground.Some are playing basketball,some are playing Pingpong,the others are playing football.
定冠词the 表特指,the others 一定范围内,除去前面提到的人或事,剩下的那部分
单独的others就是指无特定范围内的其他的,如;一些人认为上帝存在,另一些人并不这么想.即：Some people believe there is God,others don't think so.
