that did not just happen

来源：百度知道编辑：UC知道时间：2024/09/24 12:27:50

这句话后面那个 happen 为什么不用过去 happened ？是前面有了did 吗。如果加行吗？

不行啊
前面有didn't，只能用原型

病句
That just didn't happen
只要有did，都用原型

否定式的时候必须这样吧？
肯定的时候就是 that just happened
不太清楚了，语法有些忘了。。。。

happen的过去式否定要借助于助动词did，did已经表示过去了，所以后面就用happen!

在这句中，did作为助动词，跟在其后的任一动词都为原形
