The three common auxiliary (helping) verbs used in English are;
to be, to do, to have.
Auxiliary verbs are extra verbs that help or compliment the main verb in a sentence. We can say they «join up in partnership» with the main verb to add more information such as about the action, mood, voice and timing of the main verb.



Present progressive

Be is used together with the main verb in a sentence to form the passive voice and continuous tenses.

Maria is considering a trip to the countryside.
She is considering a trip to the countryside. 

The verb «to be» has teamed up with the verb «to consider» making the progressive present tense. (so the action is currently happening).

The auxiliary verb is «to be» and the main verb is «to consider».  The verb “to be” is most often used to form the progressive tenses which show when an action took place. We will see the verb «to be» used alot with the present participle, that is verbs ending «ing».

Past progressive

Maria was considering a trip to the countryside.

Future progressive

Maria will be considering a trip to the countryside.
