Present Continuous Tense Usage:

It is to be noted that all English simple sentences have SVO structure.
S subject ( Doer of an action, a noun / pronoun) + V verb ( action, state of action ) O Object ( receiver of action, noun/ pronoun)

1:Continuety of an event or action:
Present Continuous tense is used to show continuity of any action or activity

2:Unfinished action
Present continuous used for something happening at the moment of speaking. These actions usually last for quite a short time and they are not finished
• I'm chairing the conferees right now.

3. Temporary situation
We also use present continuous tense to talk about temporary situations, even if the action activity isn't happening at that moment.

We can use the present continuous for temporary or new habits (for normal habits that continue for a long time, we use the present simple). We often use this with expressions like 'these days' or 'at the moment'.

Continuous tense is also used to show future planning In this case we have already made a plan and we are pretty sure that the event will happen in the near future.
