PLEASE ANSWER We form the perfect verb tense by adding a form of the helping verb (be, have, do) to the past participle. * be
have
do

We form the perfect tenses by using the verb *to have* as an auxiliary verb and adding the past participle of the main verb. For example we form the present-perfect tense by using the present tense of have (has or have) and adding the past participle of the main verb.

Those helping verbs are named *auxiliary verbs* . And the common ones are to be, to have, and to do. They appear in the following forms:

To Be: am, is, are, was, were, being, been, will be

To Have: has, have, had, having, will have

To Do: does, do, did, will do
