Do you ever hear about this material before? If you are not, please pay attention my explanation about this material and read this material carefully. Oke, check this out.

What are ‘Auxiliary Verbs’?

Auxiliary verbs are also known as ‘helping verbs’.

Auxiliary (or Helping) verbs are used together with a main verb to show the verb’s tense or to form a negative or question.

Do / does / did

Do is common for forming questions and making negatives.

Did is used for do and does in the past tense. Do and does is never used for the past.

In statements

I do my homework.
You do the laundry.
We do the washing up.
They do yoga.
He/she does the cleaning.

In questions

Do I know you?
Do you live here?
Do we have time?
Do they come from Vietnam?
Does he/she drive to work?

Be = am / is / are

Be can be used as an auxiliary verb or the main verb in a sentence.

Is tells us that an action is happening now or is going to happen in the future.
Be is also used to make passives.
Are is used for they and we.
Was is used for the past tense of am and is.

Have = has / had

Have is used to make the present perfect tense (it is always followed by the past participle).

Has is used for the third person singular.
Had is used for past tenses especially the past perfect tense. It describes an action that began in the past and continues into the present or that occurred in the recent past.

In statements

I have a dog.
You have something on your shirt.
We have seen it before.

There is a further set of auxiliary verbs known as modal verbs or modal auxiliary verbs. These combine with other verbs to express necessity, possibility, intention, or ability. The modal auxiliary verbs are must, shall, will, should, would, ought (to), can, could, may, and might. For example:
