Unit 1: Present Tenses & Essential Verbs

1. The Verbs ‘To Be’ and ‘To Have’

The verb ‘to be’ describes existence, states, or characteristics (e.g., I am a student, They are tired). We often use contractions in speaking and informal writing (e.g., I’m, You’re, She’s). The negative is formed by adding ‘not’ (He isn’t or He is not).

The verb ‘to have’ expresses possession, ownership, or characteristics (e.g., I have a car, She has blue eyes). In the negative present simple, we use ‘don’t have’ or ‘doesn’t have’.
