Who went to a park yesterday?和Who did went to a park yesterday?哪个对?为什么?

问题描述:

Who went to a park yesterday?和Who did went to a park yesterday?哪个对?为什么?
应该是Who went to a park yesterday?和Who did go to a park yesterday?哪个对?为什么?

第一个语法是对的,意思是谁昨天去公园了.
第二个时态错了,did是助动词,后加动词原形就可以.如果一定要用这样的表达,应该是who did go to THE park yesterday?意思是,谁昨天确实去公园了,强调问法.
