We use the verb ''TO BE'' to express feelings and emotions.

The past simple tense is a verb tense form that indicates that an action is completed in the past. For regular verbs, we add -ed. For irregular verbs, there is a special past tense form.

How to construct a sentence in the past simple.
Affirmative (+)
Subject (I, you, he ,she etc) + verb in past tense+ rest of the sentence: I swam yesterday,
Negative (-) When we use the negative, we don’t change the main verb. We use ‘didn’t’ instead. I didn't SWIM yesterday
Question (?)
To make a question, we add DID at the beginning of the sentence and we don’t change the main verb.
Did I swim yesterday?
