Irregular Verbs

    Irregular verbs do not take an -ed in the past tense.

For example, let's take the infinitive verb to go.

        present tense: He goes to the movies every week end.
        past tense: He went to the movies yesterday (simple past).
                                                           OR
                           He has gone to the movies (present perfect).

    This example shows that irregular verbs change forms in the simple past (he went) and when used
with a helping verb (he has gone).

    More examples:
                 (to do)    present tense: My son does his homework every night.
                                past tense: My son did his homework last night.
                                                    My son had done his homework when his friend called.

               (to cost)    present tense: This semester my tuition costs more than what I thought.
                                  past tense: Last semester my tuition cost more than what I thought.
                                                      Last semester my tuition had cost more than my trip to Europe.

Attention!!! The verb "to cost" shows that a verb can remain the same in the present and past.
So, remember that the only difference between irregular verbs and regular verbs is that irregular verbs
do not take an -ed in the past tense. Do not think that irregular verbs change form in the past. It is true
in some cases but not all. Look at the verb "to cost."

Exercise

Identify irregular verbs in the following passage by Guy de Maupassant:

    The next day she went to her friend’s and told her about her distress.

             Mme. Forester went to her mirrored wardrobe, took out a large casket, brought it, opened
           it, and said to Mme. Loisel:—

             “Choose, my dear.”

             She saw at first bracelets, then a necklace of pearls, then a Venetian cross of gold set with
           precious stones of an admirable workmanship. She tried on the ornaments before the glass,
           hesitated, and could not decide to take them off and to give them up. She kept on asking:—

             “You haven’t anything else?”

             “Yes, yes. Look. I do not know what will happen to please you.”

             All at once she discovered, in a box of black satin, a superb necklace of diamonds, and her
           heart began to beat with boundless desire. Her hands trembled in taking it up. She fastened it
           round her throat, on her high dress, and remained in ecstasy before herself.
