PRESENT CONTINUOUS

Example: I am watching TV now.
he is not reading a newspaper now.
To make a statement in the present continuous we need the present of verb to be (AM/IS/ARE) + the -ing form of the verb we want to use
I AM READING a book
She IS DRIVING a red car
They ARE HAVING a shower
To make negative sentences we just add NOT after verb to be.
I am not reading a book
She is not driving a red car
They are not having a shower
To make questions we just place the verb to be before the subject.
Are you reading a book?
Why is she driving a red car?
Are they having a shower?
