Module 3 - 'Do" as auxiliary / "Do" as a verb - (we 'do' things)

SIMPLE PRESENT DO / DOES
Affirmative Negative Interrogative

You catch the ball. You don't catch the ball. Do you catch the ball?
He catches the ball. He doesn't catch the ball Does he catch the ball?

DO / DOES are used in the Simple Present Tense in the Negative and Interrogative form when we don't have Verb TO BE in the sentence .

I, YOU, WE, THEY - use DO / DON'T.

For HE, SHE, IT ( = 3rd person) use DOES / DOESN'T.

In the affirmative S / ES or IES is added to the verb in the 3rd person, but in the Negative and in the Interrogative the verb loses the 'S' 'es' or 'ies' because the auxiliary verb (DOES / DOESN'T) provides the 'S' for the 3rd person.

Example:



Affirmative Negative Interrogative
She loves Bob (She = 3rd person) She doesn't love Bob Does she love Bob?


When you ask a question with the auxiliary verb DO / DOES, you answer the question with DO / DOES too.

There are two types of answers:



Complete answer: Ex: A: Do you like candy? - B: Yes, I like candy.



Short Answer: Ex: A: Do you like candy? - B: Yes, I do.

The 3rd Person



Generally, in the Simple Present Tense an S is added to the verb in the 3rd person (He, She, It).

Ex: I dance - She dances

When the verb ends in Y preceded by a consonant, it loses the Y and an IES is added to the verb.

Ex: I study - She studies

When the verb ends in Y preceded by a vowel just add an S to it.

Ex: I play - She plays.

When the verb ends in SS, SH, CH, X, Z, add ES to it.

Ex: I kiss - She kisses

I brush - She brushes

I watch - She watches

I fix - She fixes

They buzz - It buzzes

When the verb ends in O preceded by a consonant, add ES to it.

Ex: I do - She does

When the verb ends in O preceded by a vowel, add S to it.

Ex: I radio - She radios
