She will help with the cooking.
(The phone rings) I'll get it.
|It is used to talk about plans and intentions. (An intention is a plan for the future that you have already thought about.) It is also used to talk about predictions based on present evidence.||We are going to buy a flat next week.
What are you going to have for dinner today?
There are clouds in the sky. It's going to rain.
|It is used to talk about plans or arrangements (something that you planned and prepared so that can happen – solid arrangements or plans).||I am meeting my mother at the airport.
Our cousins are visiting us this summer.
|It is usually used to refer to future events that are scheduled (and outside of our control).||The train departs at 6 pm.
I leave Barcelona at 5 am and I arrive in Sydney at midnight the next day.
