杭州交通信息网康熙王朝上朝音乐:do的强调作用
来源：百度文库 编辑：杭州交通信息网 时间：2024/04/29 22:20:00
在过去式当中，do可以变成did吗？
At that time, I did think he was right.这个句子对不对？
At that time, I did think he was right.这个句子对不对？
do在强调时和句子时态一致，可以变did
句子没问题
一定要变成did,因为在过去式中要用动词过去式，这才能表现出这句子是过去式。如：I did my homework yesterday.有时do(did)也作为助动词，如：I didn't do my homework yesterday.
You are right!
You did make a right sentence.
对的。 句子为过去式，作为强调的do也要跟着变成过去式。
当然，而且必须。呵呵
应该是对的,因为他们都说是对的得嘛
