Present Continuous

Use 1:Now                  
We use it to express the idea that something is happening now, at this very moment. It can also be used to show that something is not happening now.

e.g.:
You are learning English now.
We are not listening to music now.
Are they watching TV now?

Use 2:Longer actions in progress now
In English “now” can mean: this second, today, this month, this year, this century and so on. Sometimes, we use the Present continuous to say that we are in the process of doing a longer action which is in progress even though we are not doing at the time of speaking.

e.g.:
I am studying to become a doctor.
I am not reading any books right now.
Are you working on any project?

Use 3:Near future
Sometimes, we use the Present continuous to indicate that something will or will not happen in the near future.
e.g.:

I am meeting some friends after work.
He is not going to the party tonight.
Are they visiting their parents next weekend?

Use 4:Repetition and irritation with "always"
When we use the present continuous with words such as “always” or “constantly” we want to express the idea that something irritating or shocking often happens.

Ps: those adverbs appear always between “be” and “-ing”.
e.g.:
She is always coming to class.
He is constantly talking.
I don’t like them because they are always complaining.

Structure:
Subject+ to be verb+ ing verb+ comp.


Ps: as all examples are showing.
