were和was的区别 is are were是are的过去式 表示复数. was是is 的过去式 表示单数. eg: there was a slide on the playground. there were many trees on the playground. children were happy yesterday. amy was hungry yesterday. did是助动词do和does的过去式,而was/were是be动词am、is/are的过去式。 一个句子中,如果没有be动词,发生动作要用助动词do或does. 例如:i am a student. 问句是:are you a student? 有be动词所以直接用are提问。 i worked in an international company 2 years ago. 句中没有be动词,所以要用助动词代替,问句是: did you work in an international company 2 years ago?
was, were 是 系动词 be 的一般过去式,was 与 am,is对应,were与are对应 I am a teacher (我是一名教师) I was a teacher(我以前是一名教师,现在不是了) He was my friend. (他以前是我的朋友,现在不是了,或者他已经过世了) He is my friend. (他是我的朋友) You were my love. (你是我曾经的爱人,现在不是了,或者现在你已经不在人世了)
