The SIMPLE PAST TENSE is used to talk about a completely finished action in the
past.
The auxiliary
used in this tense is DID. The auxiliary is only used in negative and
interrogative sentences. In the affirmative, we don't use DID but the verbs in the past (check STRUCTURE below).
SIMPLE PAST is commonly followed by
adverbs that indicate the past such as: yesterday, last night, last month, last
year, a year ago, a few hours ago, a month ago, etc.
We have 2 kinds of verbs in the past: the regular
and the irregular verbs. In regular verbs we add –ED (Worked, walked, watched, cleaned, etc.). In
irregular verbs, the only way to remember is by practicing and checking a verb list until you memorize them.
REGULAR VERBS -
EXCEPTIONS:
1) In verbs ending in –Y that have a consonant
before, we cut the –Y and substitute it by –IED: Study = Studied (different from play, that has a vowel before
= played)
2)
In verbs ending
in –E, we just add –D: danced
3)
In verbs with
one syllable ending in consonant + vowel + consonant, double the last
consonant: stopped
4)
In verbs with
more than one syllable ending in vowel + consonant that have the last syllable strong
(tônica), we double the last
consonant: permitted
IRREGULAR
VERBS:
1) Some irregular verbs don’t change. The context is what indicates if the
sentence is in the simple presente or simple past.

STRUCTURE
INTERROGATIVE
DID + SUBJECT + VERB (INFINITIVE WITHOUT “TO”) + (COMPLEMENT)
Did you watch TV yesterday?
NEGATIVE
SUBJECT + DID + NOT (or DIDN’T) + VERB (INFINITIVE WITHOUT “TO”) + (COMPLEMENT)
I did not (OR didn’t) watch TV yesterday.
AFFIRMATIVE
SUBJECT + VERB (regular/ irregular in the past) + (COMPLEMENT)
I watched TV yesterday./ I went to school yesterday.
To watch
(regular verb) - watched
To go
(irregular verb) - went
Observe that we only used the verb in the past in the affirmative sentence. In interrogatives and negatives the auxiliary DID shows that the sentence is in the past, so we don’t change the verb to past.
We can use DID in affirmative sentences, but to emphasize:
I really liked the movie. = I did like the movie.
