English uses verbs in the past simple tense to refer to actions, situations, or events
That are finished and that happened before now. There are three ways to form simple past
tense in English. One way is what happens with the verb be: it uses the special forms was and were. Another way is what happens with regular verbs (They are called regular because they all add the same ending—ed—or some variation on it.)
The past simple Tense: Regular Verbs
English regular verbs change their form very little (unlike irregular verbs). The past tense and
Past participle of regular verbs end in –ed, for example : work, worked, worked
Regular verbs make their past tense by adding – d, ed , or (if the verb ends in a consonant + y), changing the y to I and then adding – ed.
