请教一下英文的用法 什么时候要用didn't 什么时候要用wasn't 总是弄不清楚 thanks
hi 大家好 &nbsp;我总是分不清在英文中什么时候要使用didn.t &nbsp;和wasn,t 什么时候要有be 动词什么时候不要加be 动词 &nbsp;感谢你的回答 &nbsp;谢谢～

You could say "I didn't go.... (somewhere: e.g. to the beach 海滩）I didn't know that (我还不知道）You could ask a rhetorical question "Didn't you say you went to the beach?" 等等You could also use wasn't rhetorically "Wasn't that the beach you went to?"Hope that helps!

感谢你的回答 &nbsp;在英文的past simple 当中 什么时候用didn't 什么时候用wasn't &nbsp;这两个我总是分不清楚 &nbsp;eg. the weather &nbsp;wasn't very good yesterday 按照文法来说 应该是past simple 的形式 &nbsp; 那就是 did‘t &nbsp; 这点我很疑惑 &nbsp; 希望你能帮助我解答这个问题 &nbsp;谢谢 thanks～

很简单啊，首先did和was分别是do和is的过去式，想表达"是"的意思就用相应人称的be, "我是am人" "它是is狗"；想表达某个动作就用do；如果想要表达一件"正在做"的事，就要be+doing连用。"我在走路I'm walking."
