3. Language Focus
Auxilliary Verbs
•What are verbs?
! Remember, verbs are action or state of being words.
Ex. The boy kicked the ball. (action)
Ex. The book is interesting. (state of being)
Auxiliary verbs are sometimes called helping verbs because they help
us conjugate other verbs (change a verb from its basic form). They are
also used when making negative statements or asking questions with
other verbs.
Ex. I did not see Ali yesterday. (negative)
Ex. Can you please close the door? (Asking a question)
Auxiliary verbs are also used to express shades of time and mood (what
the speaker thinks about something).
Ex. I was studying for the Math exam yesterday. (time—Past
Progressive)
Ex. I do not like apples. (mood)

4. Usage 2.1
Do, Does & Did
•! Remember
It is also common to use do, does and did as auxiliary verbs (or helping verbs)
together with another verb in its base form to make negative sentences, ask
questions, or for adding emphasis.
• Make negative sentences with don’t, doesn’t and didn’t
Ex. I didn’t sleep early.
Ex. Your friends didn’t get the e-mail.
• Use do, does and did to add emphasis in the same way you answer a
question. To do this, place do, did or does before the main verb.
Ex. I do play the guitar.
Ex. I did get to class on time yesterday.
Ex. My brother does need help with his homework.

person or thing that does the action) + base form of the verb + the rest of the
sentence.
Ex. Do you remember Ali’s message? (positive)
Ex. Don’t you remember the agreement we had? (negative)
•You may add a one-word time expression, such as always, usually, or often
between the subject and the verb.
