Objective
We will learn and identify auxiliary verbs to use them in sentences.
Antecedent
Auxiliary verbs are verbs that modify the meanings of other verbs in the sentence.
They do not have meanings of their own.
Auxiliary verbs are needed to form many of the tenses.
The most used auxiliary verbs are the verbs
to be
,
to do
and
to have
.
They are used before the main verb.
Their purpose is to change time or emphasis.
Unlike other structure words, these auxiliary verbs
1. Can have inflectional endings (-s, -ing, -ed, -en)
2. Can also function as main verbs.
There are three types of verbs: action, linking, and auxiliary. Today we will focus in auxiliary verbs only.
A verb tells about an action or a state of being.


Do
you like German food?

Does
your mother speak English?

Did
you come to school yesterday?
• Why
are
you talking? You should
be
listening to me!
• I
was
having a bath when you called!
• A new road
is being
built behind the school.

Have
you done your homework?
• My father
has
never visited the USA.
• How long
have
you
been
living in Germany?
• By this time next year I
will have been
learning English for 35 years!
Examples:
“Be” verbs
They help show a state of being or a state of existing, they don’t show any action.
• Katy is watching television. (This shows a continuous tense.)
• A letter is written by Rita.
(This example shows the passive tense.)
Have.
The auxiliary verb have is used to make perfect tenses which show actions that are already completed.
• I have finished washing the dishes. (Dish washing is complete!)
Do
The verb “do” can perform a variety of functions:
• To make negatives: I do not care for broccoli.


• To ask questions: Do you like broccoli?


• To show emphasis: I do want you to eat your broccoli.


• To stand for a main verb: Sam likes broccoli more than Carmen does.
Modal auxiliaries
The modal auxiliaries are:
1. Do not use inflectional endings (-s, -ed, -ing, -en)
2. Cannot function as main verbs.
3. Some can refer to the present or the future at the same time (without using will).
4. They are followed by a verb in its base form without the to.
5. None of them can be used without a main verb.
Look at these examples:
Contracted auxiliaries
I'm playing tennis tomorrow.
I am playing tennis tomorrow.
Why did you not call me yesterday?
Why didn't you call me yesterday?
Why did America not join the war until 1941?
Why didn't America join the war until 1941?
• She
's
not going to the dance.
• She is
n't
going to the dance.
• I have
n't
seen him for ages.
• I
've
not seen him for ages.
Short form
Points to remember:
• Not every sentence has or needs a helping verb.
• Sometimes other words separate the helping verb and main verb in the sentence. The word “not” is an example. Sarah couldn’t run as fast as Beth. Here the word “not” separates the helping verb “could” from the main verb “run.”
• Any time you see a verb ending in “ing”, a helping verb usually accompanies it.
Activity
Complete each sentence with the correct auxiliary verb.
am / are / is / do / does / have / has
1. _______ you usually send postcards home when you are on holiday?
2. I _______ not working today.
3. _______ she given you the book yet?
4. The boy _______ playing with his toys.
5. I _______ not seen that film yet.
6. Who _______ told you to do this?
7. Where _______ he go to school?
8. What _______ you doing at the moment?
9. Amy _______ not go by bus very often.
10. Marc _______ never travelled by plane before.

The full form is common in spoken language when the speaker wants to emphasize what he/she is saying.
For example:
Why don't you call him?
• I
have
called him.
• I
do not
want to see him again.
Conclusion
Auxiliary verbs are used every day in the English language so figuring out how to recognize them and when to use them comes second nature after a while.
