The Verb to Be
The verb TO BE has EIGHT different forms. BE, AM, ARE, IS, WAS, WERE, BEEN and BEING.

The base form of the verb TO BE is used in imperatives, after modal verbs and in the infinitive.

For example; "BE quiet!", "Don't BE so naive", "In an exam you must BE quiet" and "Please try TO BE quiet."

In the present tense we use THREE different forms; AM, ARE and IS.

I AM a teacher, I AM NOT a student.
You ARE a good boy but you AREN'T very intelligent.
Sara ISN'T my best friend, she IS my sister.
We ARE on holiday so we AREN'T going to do any work.
They ARE studying English but they AREN'T taking it very seriously.

Notice that, to make the verb TO BE negative we put NOT (or the contraction N'T) after the verb.

In the past tense we use TWO different forms; WAS and WERE.

I WAS in England last week, I WASN'T in France.
You WERE late for class and you WEREN'T prepared for the exam.
Sara WAS studying all night so she WASN'T nervous.
We WERE on holiday at the beach so we WEREN'T able to come to your party.
They WERE happy to help, but they WEREN'T very helpful.

The GERUND of the verb BE is BEING. We use it in continuous formations, and we also use it as a subject, as with all gerunds.

"You are BEING very good"
"BEING quiet is hard for children"

Finally, the participle of the verb BE is BEEN. We use it in the present perfect tense and the past perfect tense.

I have BEEN to England.
He had BEEN quiet for a long time.
We've BEEN making cakes.

All passive formations and continuous formations have a form of the verb BE in them.

I AM studying, I have BEEN studying, I WAS studying.
He WAS chosen, he has BEEN chosen.

In unit 17 we will study more about the verb BE as an auxiliary verb.
