为什么是What happened?而不是 What did happen?不是用do来构成有行为动词动词的疑问句吗?还有是 what you happened?而不是 what did you happen?

问题描述:

为什么是What happened?而不是 What did happen?
不是用do来构成有行为动词动词的疑问句吗?
还有是 what you happened?而不是 what did you happen?

What作的是主语,后面直接跟谓语动词。
你说的俩个句子都不对,应该是:
What happened to you?
你发生什么事了?

What happened?”属于陈述句、肯定句,实义动词用于肯定陈述句的一般结构为(以一般过去时为例):“主语+过去式”
而did是助动词,这里是多余的

已经有疑问词what,可以直接引导一个疑问句,无需添加助动词do
问题补充:还有是 what you happened? 而不是 what did you happen?
回答:都不是,正确的是:what has happened to you?

what是主语 happen是谓语

What作的是主语,后面直接跟谓语动词
