does is not a modal verb
when our tense is in the past we can use the helping verb had
The relationship between a helping verb and a verb tense is how you use the helping verb. If used like "I did try out for ..." then the relationship is did. As used as comparing, both come before the action verb.
You can use it as a helping verb or as a possessive verb.Ex. I have answered some questions on this site.Ex. 2: I have one nose.
Verb phrases are grammatical phrases that show action. They contain an action verb and at least one auxilary (helping) verb.A helping verb is a verb that does not show action. There are 23 helping verbs: do, does, did, has, have, had, may, might, must, could, would, should, can, will, shall, is, am, are, was, were, be, being, been. I know personally because my teacher made me memorize this list.I am 11 as of 2008 when this was submitted and I answered the Oregon Trail question.Also a verb phrase can also be a verb + preposition or adverb. They are called phrasal verbs.eg look out / brought up / turn down / blow up.my teacher helped me memorize them by saying: is are was were be been am has have had will and shaw could would should do dose did must might may and can.
there are many uses of have, has and had. because have is a verb and also a helping verb. as a verb it is used for possession. for instance, i have a car, it means, i possess a car. as a helping verbs, have and has are used for present and had for past, always with a third form of verb.
I have a computer.
The past participle is always used with a helping verb: perfect tenses: had walked / have waited / had seen passive verb phrase: am known / is eaten / are driven / was found / were seen
An example of this is "She has had a lot of work to do"
You certainly can use a helping verb, but it depends on the tense. If it's a simple past tense, you don't need one: Who ate my sandwich? Who took my pen? But if you are using a past perfect tense, the helping verb is necessary, to show an action that happened earlier in the past: Who has seen this movie? Who has read the chapter? Other examples of interrogative sentences with who asking the question but no helping verb: Who is Alice? Who are you? Who was the one? Who has the answer?
No you can't, it is not possible. Does is the verb in questions starting with does. You can make questions starting with is:- Is this you car?
