Present Progressive

We use the present progressive when we refer to something that is happening now.

To write sentences using the present progressive you have to follow the following structure.

(+) Pronoun or noun + verb to be + verb ing + complement
(-) Pronoun or noun + verb to be + not + verb ing + complement
(?) Verb to be + Pronoun or noun +  verb ing + complement ?
