Auxiliary verb (grammar) is a verb such as be, do(Do)(does for 3rd person.) and have used with main verbs to show tense,moods etc.to form questions and negatives.
Do can be a full verb or a special finite:-
He does his job well. He did good job.What were you doing this days? The holiday did me good.What does he do for a living? He doesn't do anything.
When do is a full verb it forms its interrogative and negative with the special finite do;as shown(does he do---doesn't do)
As a special finite do is used:-
(1) To form negative and interrogative of all verbs except have,need, dare.
(2)For Question phrases with all verbs not special finite,eg:-
You understand me, don't you?
You didn't come here by train, did you?
(3)To avoid repetition of a full verb,esp.in short answers,to make question-tags:-eg:-You live in Tainan, don't you?She doesn't work here, does she ?
Do you understand that? Yes,I do. No, I don't.
I like swimming, so does Mary.
David doesn't like hard work, neither does John.
Those wishing to go may do so.
May I help myself to a Chinese dim-sum? Do, by all means.
They said Peter wouldn't pass his Exam, but he did.
(The last two examples show the emphatic use of do avoiding the repition of a verb)Avoid repeating=eg:-He plays better than he did a year ago. She works harder than he does. Who won the game ? I did.-I love apples. So did I. I don't want to go back. Neither do I
(4)With the Imperative of verbs,eg:-
Do come and see us. Do have some more of this Chinese dim-sum. Do stop that eating noise.-----a request.
Do not(don't)(does) is always used before a full verb to make the negative imperative,eg:-I don't like sour fish. They didn't go to China.Don't forget to e-mail me or to write. Does she speak Hard-kar language ?
Do not do that. Don't go till I tell you.don't be late.Never be cruel or unjust.(negative imperative)Do be careful when you cross the road.(affirmative imperative emotion)
Need also used as an auxiliary verb follow by infinitive with to:-eg:-
He doesn't need to go.

Do you want to drink something?
反正do出現的目的就是要輔助動詞,就是want~ 舉個例:Are you tired?
由do/does當前 當句型是疑問句或一些直訴句(直訴句就是 I love you 這種有'主詞" "動詞" 還有"受詞"組合的最基本句型,缺一不可) do/does的詞性及為"助動詞"
我想大大要問的句型應該是這個,ex. I don't want to eat chicken.
重點來了!! 假如我今天要說的是 I want to eat chicken.你有沒有發現 這時do不見了?
