NEGATIVE FORM:

In the negative form we need to use the auxiliary did + not (didn’t). remember that when we use the auxiliary we put the verb in the INFINITIVE form. The auxiliary didn’t is used in the negative form with verbs that are not to be. DO NOT USE DIDN’T WITH WAS OR WERE!!!

TABLE # 1

Subject	Auxiliary (did) + not	Infinitive
I You She He It We They	Did not (didn’t)	Study Work Play Go Eat Arrive Live

Ejemplos (TABLE # 2):

Positive form	Negative form
I went to school	I didn’t go to school
She studied all night	She didn’t study all night
They ate a lot	They didn’t eat a lot
We had lunch	We didn’t have lunch

• Simple Past (QUESTION FORM) – TABLE # 3:

In the question form we need to use the auxiliary “Did” and we have to write the verb in the INFINITIVE form

Auxiliary (Did)	Subject	Infinitive
|| | | Did | | |	I You He She It We You They	Study Work Play Go Eat Arrive Live Sleep

We can also place the question word before this structure.

QW + DID + Subject+ Verb (Infinitive)

Examples:

- What did you do yesterday?
- Where did Maria go last week?
- What time did Pedro leave the party?
- When did Sarah get married?
- How many bottles of beer did they drink?

• Let’s compare present simple with past simple

TABLE: 4

Present Simple	Past Simple
(-) I don’t study	I didn’t study
(-) She doesn’t work	She didn’t work
(?) Does she study?	Did she study?
(?) Do you like movies?	Did you like the movie?

*** Como vemos en esta comparación, lo único que cambia es el auxiliar. Recuerden que el auxiliar DID (ademas de do y does)APARECEN EL LA FORMA NEGATIVA E INTERROGATIVA CON VERBOS QUE NO SON TOBE.
