was和were都表示“是”，过去式，和be动词用法一致。
区别在于：
1、was 表单数-是 （is的过去式）
例如：I was beautiful five years ago.
2、were 表复数-是 （are的过去式）
例如：They were workers.
was和were的区别，各自怎么用
区别是用法不同，举例如下：
I/he/she was a student five years ago.
they/you were students five years ago.
there was a book on the table.
there were ten books on the table.
was和were的区别，各自怎么用
was是is和am的过去式，用于接，除了第二人称以外的单数主语，were是are的过去式，用于接所有复数和第二人称you.如:I was at home yesterday. You were busy last Sunday.
