In this lesson, you will learn the affirmative form (positive), question form and negative form of the verb BE in both the present simple tense and past simple tense. I also explain the contracted forms for the affirmative and negative.
The verb "to be" is an irregular verb in English. Its form is therefore different to all other verbs. This verb is used a lot in the English language. It is therefore very important to learn the form by heart.
