请教一下do does did 的用法。跪求！！！！！！！！！！！！！！

你好，同学

你说的这些词都是助动词，do用在一般现在时的除了第三人称单数以外的所有人称的疑问句，否定句中，如
Do you go to school by bike every day?
Do they have lunch at 12 every day?
No, they don't. （ don't= do not.)

does用在一般现在时第三人称单数时的疑问句，否定句中，如
Does he like swimming?
Does she have English class every day?
Tom doen't go to school by bus.

did 用在过去时的疑问句和否定句中，如
Did you see a film yesterday?
Did they play basketball last Sunday?
They didn't go to Beijing last year.

希望能帮到你，祝更上一层楼O(∩_∩)O
有不明白的请继续追问(*^__^*)

do和does是一般现在时的助动词， did是一般过去时的助动词，does

用于第三人称，而do是第一人称，用于疑问句

eg，How do you know the answer?

How does she know the answer?

Where did he go yesterday?
