Future Simple 1) things that will happen or the speaker is sure will happen - I’m very worried about my examination next week. - Don’t worry. You’ll pass. 2) when we decide to do something at the time of speaking (on-the-spot decision) - What would you like to drink? - I will have a lemonade, please. - Did you phone Ann? - Oh no, I forgot. I’ll do it now. Be Going To 1) plans and intentions that we have for the near future, what we have already decided to do I’m going to spend next summer travelling around the world. Tom hasn’t made the coffee yet, but he’s going to make it. 2) to say what the speaker thinks will happen (something in the present situation makes the speaker sure about what will happen): Situation: It is 8.30. Tom is leaving his house. He has to be at work at 8.45 but the journey takes 30 minutes. => Tom is going to be late. 3) predictions about the future, after such words as: to think be sure probably to believe be afraid perhaps will to expect promise certainly to hope I expect Carol will get a promotion. Present Continuous (with a future meaning) 1) We use the Present Continuous when we are talking about what we have already arranged to do: I am seeing my doctor next week. - Are you playing football tomorrow? - Yes, but Tom isn’t playing. He has hurt his leg. Present Simple (with a future meaning) 1) We use the present simple when we are talking about timetables, programs (for example, for public transport, cinemas etc.): The train leaves Plymoth at 10.30 and arrives in London at 13.45. Tomorrow is Wednesday. NB! WE DON’T USE THE PRESENT SIMPLE FOR PERSONAL ARRAGEMENTS! Instead, we use the Present Continuous. I’m meeting Ann at 4 p.m.
