to be + not

If you want to say something is not true + a form of to be:
just add 'not' after am/is/are.


 

I am not I'm not -
You are not You're not You aren't
He is not He's not He isn't
We are not We're not We aren't
They are not They're not They aren't


Now do exercise 11 and 12 on page 35 in your workbook.
