Unit 5: NEGATIVE SENTENCES

We put not after the first word of the verb. In speaking, we often use the short form (n't).

With the verb be

I am not a thief.
They aren't coming.
It wasn't very cold there.
He is not a teacher.

Put the correct form of the verb do (Unit 15) before not.

[A]:AFFIRMATIVE, [N]:NEGATIVE

[N] He does not work on Saturdays.

[A] These shops sell food.
[N] They do not sell food.

Put not after the first auxiliary verb.

He wouldn't have gone if he had known.
They aren't doing math this term.
