"He did his homework."改为疑问句,
老师给的答案是：Did he do his homework?可我觉得“do”的后面不应该加上es吗？“he"是三单啊！

分析一下吧,这个陈述句中有实义动词“did”,变为问句的是后就得以助动词“did”看是,老师给你的是正确的.因为有助动词DId 所以此句中的动词应为原型.
再问：哦，我懂了。可是，如果有个句子，did放在动词的后面，那那个动词还是原型吗？还有一个疑问句："Did his friends go to that movie last week?"中的”friends“，为什么可以加s，开头不是有个"Did"吗？？
再答：这句话变为陈述句怎么变？His friends went to that movie last week. 再变为一般疑问句就如你所问的了。助动词不言而喻就是起的一个辅助作用，did 就像说明语气的一样。建议你看一下语法书，为什么看语法书，知道哲学就肯定知道，共性和个性。共性和个性就像语法，和各式各样的句子。学语法就是要你找到句子中那些可以说是恒定的东西，不学语法，英语水平高不到哪儿去。同样语文不行，英语也好不哪里去。你应该是初中生吧好好学习哦，
再问：但不是助动词后的动词用原型吗？但为什么friends可以加s?其实我是高中生了，只是成绩不太好，想恶补一下！！
再答：我说的原型是说的动词变形与否。他们给你的回答就挺好的，他们说的和我要说的差不多。好好努力吧
再问：谢了@！
