Recall the 9 modals: shall, should, will, would, can, could, may, might, must
Recall the BE: is, am , are, was, were
Recall the HAVE: has, have, had. As HELPING verbs.
For all of them, just add not after the first element of the verb group.
He will come. ==> He will not come.
She can come. ==> She can not come.

They were workers. ==> They were not workers.
He is coming. ==> He is not coming.
He has played tennis. ==> He has not played tennis.

HAVE as Main Verbs
Here it means "own/possess or experience".
e.g. I have a car.
They had a house.
We had breakfast.
We had a meeting.
HAVE as Helping Verbs
Below, the sentences are all about "playing," not "owning"
e.g. He has played tennis.
He had played tennis.
He has been playing tennis.
He had been playing tennis.
Basic Formula here is, we break up the single verb into DO+ infinitive.
plays = DOES + play
play = DO + play
played = DID + play
We go to the party. ==> We do not go to the party.
I play football. ==> I do not play football.
She likes food. ==> She does not like food.
Jane plays the guitar. ==> Jane does not play the guitar.
We went to the party. ==> We did not go to the party.
I played football. ==> I did not play football.
She cooked food. ==> She did not cook food.
With Modals, BE, HAVE as helping,
Kick it ( the first element of the verb group) to the front of the sentence.
She can go. ==> Can she go?
Jane would sing. ==> Would Jane sing?
He is a doctor. ==> Is he a doctor?
They are winning. ==> Are they winning?
He has played well. ==> Has he played well?
We had played well. ==> Had you played well?
We break up the single verb into DO+ infinitive, and place DO at the front of the sentence.
e.g. She plays = DOES + she play + ?
They play = DO + they play + ?
Jane played = DID + Jane play + ?
