PRESENT CONTINUOUS

PRESENT CONTINUOUS.

Form: [am/is/are + present participle]

Use the Present Continuous with normal verbs to express the idea that something is happening now, at this very moment.

EXEMPLES:

Positive:

You are learning English now

Negative:

You are not swimming now

Interrogative:

Are you sleeping?

In english, 'now' can mean: this second, today, this month, this year, this century, and so on. But sometimes we can use the present continuous to say that we are in the process of doing a longer action which is in progress.
