THE SIMPLE PAST

-We use Past Simple to talk about completed action in the past.
To form the past, the verb should be in the form of the past. For this we must know the regular and irregular verbs.

IRREGULAR VERB: Need to memorizer the change it has in the writing. Example:

- Verb: Became. Paast Simple: Became.
- Verb: Begin. Past Simple: Began.
- Verb: Drive, past Simple: drove.

REGULAR VERBS: Form the past by adding " ed" to the verb.

If the verb ends in a consonant + y, y changed by i, in the past.
Example: Cry + y = Cried.

If the verb end in e, only add, d.

Example:Decide + d = Decided.

Advise + d = advised.

Agree + d = agreed.

- NEGATIVE FORM: We used didn´t or did not, for all persons.

Estructure:

Subject + Auxiliary + not + Verb (infinitive) + Complement.

Example:

We did not go to the beach yesterday.

You can use the contration the did not = didn't, example:

He did not study very much. = He didn't study very much.

They did not like painting = They didn't like painteng.

AFFIRMATIVE FORM: Irregular verb change completely their writing, so you need tomemorizar y and Add - ed to regular verb to make the past form.

Estructure:

-Subject + Verb( past form) + complement.

Example:
She cleaned her house. ( regular verb)
He traveled to Russian in 1994. (regular verb)
You ate Chinese rice.( irregular verb).
The Titanic left Southampton, England. -

INTERROGATIVE FORM: We use the auxiliary did with all the person for the past.

Estructure:

Auxiliar + subject + verb ( infinitive form).

Example:

Did she write a poem?.

Did Julian slept every day?.
