Present continuous

The present continuous is used to talk about present situations which we see as short-term or temporary. We use the present simple to talk about present situations which we see as long-term or permanent. 

In these examples, the action is taking place at the time of speaking.

• It's raining.
• Who is Kate talking to on the phone?
• Look, somebody is trying to steal that man's wallet.
• I'm not looking. My eyes are closed tightly.

In these examples, the action is true at the present time but we don't think it will be true in the long term.

• I'm looking for a new apartment.
• He's thinking about leaving his job.
• They're considering making an appeal against the judgment.
• Are you getting enough sleep?

In these examples, the action is at a definite point in the future and it has already been arranged.

• I'm meeting her at 6.30.
• They aren't arriving until Tuesday.
• We are having a special dinner at a top restaurant for all the senior managers.
• Isn't he coming to the dinner?
