Future with Present Continuous
Subject + to be + base-ing
She is meeting
The present continuous is used to talk about arrangements for events at a time later than now.
There is a suggestion that more than one person is aware of the event, and that some preparation has already happened.
I'm meeting Jim at the airport = and both Jim and I have discussed this.
I am leaving tomorrow. = and I've already bought my train ticket.
Is she seeing him tomorrow?
He isn't working next week.
Note: in the first example, seeing is used in a continuous form because it means meeting.
BE CAREFUL! The simple present is used when a future event is part of a programme or time-table. Notice the difference between:
a. We're having a staff meeting next Monday.
b. We have a staff meeting next Monday (= we have a meeting every Monday, it's on the time-table.)
The simple present is used to make statements about events at a time later than now, when the statements are based on present facts, and when these facts are something fixed like a time-table, schedule, calendar.
The plane arrives at 18.00 tomorrow.
She has a yoga class tomorrow morning.
The restaurant opens at 19.30 tonight.
Next Thursday at 14.00 there is an English exam.
Note the difference between:
The plane leaves in ten minutes (= statement of fact)
The plane's going to leave in ten minutes (= prediction based on present situation, meaning "...and if you don't hurry up you're going to miss it!")
