1,作为实义动词/行为动词,跟其他动词一样,如study, play等,do和does都是“做”的意思,都是一般现在时,主语是第三人称单数用does,其余人称用do,
例句如:We usually do our homework in the afternoon.
He does his homework in the evening.
2,作为助动词,也就是帮助主要动词构成否定和疑问等,没有意义,主语是第三人称单数用does,其余人称用do,后面的动词都用原形。
例句如:We don't like bananas. Do you like apples?
Does he like English? He doesn't like swimming.
