Do + not

If you want to say something is not true with 'to do':
just add 'not' after the form of to do.


 

I do not I don't
You do not You don't
It does not It doesn't
We do not We don't
They do not They don't


Note well:
He eats. He doesn't eat.
DO NOT add an 's' after 'eat': He eats. He doesn't eats.
That would be a double. So add the full form of the verb after don't/doesn't.

I don't sleep.
She doesn't walk. (not walks!!)
It doesn't sit.

Now do exercise 13 and 14 on page 36/37 in the workbook.
