To construct the interrogation we use
the auxiliary verb to do in past (did).
The structure is: Did + [SUBJECT] +
[VERB IN INFINITIVE (without to)]?
Example
Did you go to the super market yesterday?
Negative
The formation of the negation in "past
simple" is simpler than the affirmation.
Its structure is: [SUBJECT] + did + not +
VERB IN INFINITIVE (without to)]
Example
Silvia didn´t cook the diner
Affirmative
The structure of the "simple past"
is: [SUBJECT] + [VERB IN PASS,
END "-ed"]
Example
Ivonne ate a big ice cream
Regular Verbs
For regular verbs the
simple past is formed by
adding 'ed' to the end of
the verb. This form is the
same for all personal
pronouns (I, you, he, etc).
Example
To cook- cooked
To work- worked
To live- lived
Irregular Verbs
The simple past of some verbs
does not end in -ed, but has an
irregular shape, which is the same
for all people.
