The simple past tense describes an action which started and also ended in the past and which has no connections with the present. The simple past tense is often accompanied by a time term which relates to the past: e.g., a year ago, last month, yesterday, etc…
It is created by using the following:
Positive sentence – subject + verb in its past form.
If a verb is regular then its past form just takes –ed (if such a verb ends by e then only d is added, if a verb ends by a consonant +y, this y will change to i).
You must learn past forms of irregular verbs by heart.
They worked (work) hard.
She bought (buy) a new evening dress last week.
In a negative sentence did not is placed between a subject and verb (in every person). In this case the verb is in its basic form, ie, infinitive without to.
I did not (didn’t) meet them there.
They did not (didn’t) write the test yesterday.
In a question did is placed before a subject (in every person).
In this case the verb is in its basic form: infinitive without to.
Did you do your homework yesterday?
Did he win the match?
