TO BE: INTERROGRATIVE SENTENCES, TO BE: NEGATIVE SENTENCES
We use the verb TO BE to talk about a lot of different things. For example – about the job, person or some other thing.
TO BE – THE PRESENT SIMPLE TENSE (affirmative to be – short forms)
TO BE – THE PRESENT SIMPLE TENSE (interrogative)
We create the interrogative form by inversion where the personal pronoun and the verb “to be” change places.
She is happy. → Is she happy?
They are in the office. → Are they in the office?
We form the negative form by adding NOT after the verb to be.
