PRESENT PROGRESSIVE

The present progressive is formed by combining the verb "to be" with the present participle. (The present participle is merely the "-ing" form of a verb.)

Pattern:
S + be + V1 + ing (+)
S + be + V1 + ing + not (-)
be + S + V1 + ing? (?)

be (am, is, are)

ex:
I am walking.
I am not walking.
Am I walking?.

We are reading.
We are not reading.
Are We reading?

She is singing.
She is not singing.
Is She singing?

In English, present progressive can be used to describe what is happening now, or what will happen in the future.

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; however, we might not be doing it at this exact second.

Sometimes, the Present Continuous (Progressive) used to indicate that something will or will not happen in the near future.
Ex: I am not going to the birthdayparty tonight.

The Present Continuous with words such as "always" or "constantly" expresses the idea that something irritating or shocking often happens. Notice that the meaning is like Simple Present, but with negative emotion. Remember to put the words "always" or "constantly" between "be" and "verb+ing."
Ex: She is always coming to class earlier.
