English Language for Exams Part 30 #EL #CE
Auxiliary Verbs are the verbs be, do, have, will when they are followed by another verb (the full verb) in
order to form a question, a negative sentence, a compound tense or the passive.
The verb “be”
The verb be can be used as an auxiliary and a full verb. As an auxiliary we use this verb for compound tenses and the passive voice. Note that be is an irregular verb:
I am, he/she/it is, we/you/they are
I/he/she/it was, we/you/they were
You can tell that in the following sentences be is an auxiliary because it is followed by another verb (the full verb). (For progressive forms use the “-ing” form of the full verb; for passive voice, use the past participle of the full verb.)
He is playing football.
He was playing football.
Present Perfect Progressive:
He has been playing football.
Past Perfect Progressive:
He had been playing football.
The house is/was built.
The house has/had been built.
Future I: Th e house will be built.
“be” as a full verb
The verb be can also be a full verb. In this case, it’s not followed by another verb. If be is used as a full verb, we do not need an auxiliary in negative sentences or questions.
positive sentence: They are fifteen years old.
negative sentence: They are not fifteen years old.
question: Are they fifteen years old?
The verb “have”
The verb have, too, can be used both as an auxiliary and as a full verb. As an auxiliary we use this verb to form
compound tenses in active and passive voice. (Use the past participle of the full verb.)
