Answer:Helping verbs or auxiliary verbs such as will, shall, may, might, can, could, must, ought to, should, would, used to, need are used in conjunction with main verbs to express shades of time and mood. The combination of helping verbs with main verbs creates what are called verb phrases or verb strings. In the following sentence, "will have been" are helping or auxiliary verbs and "studying" is the main verb; the whole verb string is underlined:
As of next August, I will have been studying chemistry for ten years.
Students should remember that adverbs and contracted forms are not, technically, part of the verb. In the sentence, "He has already started." the adverb already modifies the verb, but it is not really part of the verb. The same is true of the 'nt in "He hasn't started yet" (the adverb not, represented by the contracted n't, is not part of the verb, has started).
Shall, will and forms of have, do and be combine with main verbs to indicate time and voice. As auxiliaries, the verbs be, have and do can change form to indicate changes in subject and time.
I shall go now.
He had won the election.
They did write that novel together.
I am going now.
He was winning the election.
They have been writing that novel for a long time.
Uses of Shall and Will and Should
In England, shall is used to express the simple future for first person I and we, as in "Shall we meet by the river?" Will would be used in the simple future for all other persons. Using will in the first person would express determination on the part of the speaker, as in "We will finish this project by tonight, by golly!" Using shall in second and third persons would indicate some kind of promise about the subject, as in "This shall be revealed to you in good time." This usage is certainly acceptable in the U.S., although shall is used far less frequently. The distinction between the two is often obscured by the contraction 'll, which is the same for both verbs.
In the United States, we seldom use shall for anything other than polite questions (suggesting an element of permission) in the first-person:
"Shall we go now?"
"Shall I call a doctor for you?"
(In the second sentence, many writers would use should instead, although should is somewhat more tentative than shall.) In the U.S., to express the future tense, the verb will is used in all other cases.
Shall is often used in formal situations (legal or legalistic documents, minutes to meetings, etc.) to express obligation, even with third-person and second-person constructions:
The board of directors shall be responsible for payment to stockholders.
The college president shall report financial shortfalls to the executive director each semester."
Should is usually replaced, nowadays, by would. It is still used, however, to mean "ought to" as in
You really shouldn't do that.
If you think that was amazing, you should have seen it last night.
In British English and very formal American English, one is apt to hear or read should with the first-person pronouns in expressions of liking such as "I should prefer iced tea" and in tentative expressions of opinion such as
I should imagine they'll vote Conservative.
I should have thought so.

Uses of Do, Does and Did
In the simple present tense, do will function as an auxiliary to express the negative and to ask questions. (Does, however, is substituted for third-person, singular subjects in the present tense. The past tense did works with all persons, singular and plural.)
I don't study at night.
She doesn't work here anymore.
Do you attend this school?
Does he work here?
These verbs also work as "short answers," with the main verb omitted.
Does she work here? No, she doesn't work here.
With "yes-no" questions, the form of do goes in front of the subject and the main verb comes after the subject:
Did your grandmother know Truman?
Do wildflowers grow in your back yard?
Forms of do are useful in expressing similarity and differences in conjunction with so and neither.
My wife hates spinach and so does my son.
My wife doesn't like spinach; neither do I.
Do is also helpful because it means you don't have to repeat the verb:
Larry excelled in language studies; so did his brother.
Raoul studies as hard as his sister does.
The so-called emphatic do has many uses in English.
To add emphasis to an entire sentence: "He does like spinach. He really does!"
To add emphasis to an imperative: "Do come in."
