do表示强调的时候有没有人称或者时态的变化

We do think that our son needs to be realistic.

这句话中的do表示强调，如果主语换成He的话，do变成dose吗？
如果是过去式需要变成did吗

yes, you are right

eg. He does think that his son needs to be realistic.
She does need to go to school.
I did ask you to come here.
We did say that you have to complete your work.

hope this will help you.

是的 如果主语换成He的话，do变成dose 如果是过去式需要变成did

回答正确，加10分！ 哈哈，你说的都是对的！

答案为write动词原形 make sb. do sth.使某人做某事 let sb do sth.让某人做某事 get sb do sth 使某人做某事 此上都为固定搭配,即不管动词do是什么,都为原形 在被动语态中,make sb do sth 要改成make sb to do sth 我们英语专业生在大一时老师就要求我们改过来,高中生没那么要求严格
