was和wasnt怎么用

问题描述

精选答案

关于这个问题，was和wasn't是was的缩写形式，was表示过去时中的"是"，wasn't表示"不是"。

例如：- I was at home last night. (我昨晚在家。)- He wasn't feeling well yesterday. (他昨天感觉不舒服。)注意：was和wasn't只能用于单数主语，对于复数主语，需要用were和weren't。例如：- They were at the park yesterday. (他们昨天在公园。)- We weren't able to finish the project on time. (我们没能按时完成项目。)
