Present Progressive or Present Continuous

Present Continuous or Present Progressive Verb Form

1. Present continuous, form

The present continuous of any verb is composed of two parts - the present tense of the verb to be + the present participle of the main verb.
(The form of the present participle is: base+ing, e.g. talking, playing, moving, smiling)

Affirmative
Subject	+ *to be*	+ base+*ing*
she	is	talking

Negative
Subject	+ to be + not	+ base+*ing*
she	is not (isn't)	talking

Interrogative
*to be*	*+ subject*	+ base+*ing*
is	she	talking?

Example: to go, present continuous

Affirmative	Negative	Interrogative
I am going	I am not going	Am I going?
You are going	You aren't going.	Are you going?
He, she, it is going	He, she, it isn't going	Is he, she, it going?
We are going	We aren't going	Are we going?
You are going	You aren't going	Are you going?
They are going	They aren't going	Are they going?

Note: alternative negative contractions: I'm not going, you're not going, he's not going etc.

2. Present Continuous, function

As with all tenses in English, the speaker's attitude is as important as the time of the action or event. When someone uses the present continuous, they are thinking about something that is unfinished or incomplete.
The present continuous is used:

to describe an action that is going on at this moment e.g.
You are using the Internet. You are studying English grammar.
to describe an action that is going on during this period of time or a trend, e.g.
Are you still working for the same company? More and more people are becoming vegetarian.
to describe an action or event in the future, which has already been planned or prepared (See also 'Ways of expressing the future) e.g.
We're going on holiday tomorrow. I'm meeting my boyfriend tonight. Are they visiting you next winter?
to describe a temporary event or situation, e.g.
He usually plays the drums, but he's playing bass guitar tonight. The weather forecast was good, but it's raining at the moment.
with 'always, forever, constantly', to describe and emphasise a continuing series of repeated actions, e.g.
Harry and Sally are always arguing! You're forever complaining about your mother-in-law!

BE CAREFUL! Some verbs are not used in the continuous form - see below.
3. Verbs that are not normally used in the continuous form
