There are several future forms. The one which is most often used in spoken English is 'going to', not 'will'.
The structure is:
subject + be + going + infinitive
The verb be is conjugated (past, present or future).
|+||I||am||going||to buy||a new car.|
|-||He||is||not||going||to take||the exam.|
|?||Are||you||going||to paint||the house?|
We use 'going to' when we want to talk about a plan for the future.
• I'm going to see him later today.
• They're going to launch it next month.
• We're going to have lunch first.
• She's going to see what she can do.
• I'm not going to talk for very long.
Notice that this plan does not have to be for the near future.
• When I retire I'm going to go back to Barbados to live.
• In ten years time, I'm going to be boss of my own successful company.
We use 'going to' when we want to make a prediction based on evidence we can see now.
• Look out! That cup is going to fall off.
• Look at those black clouds. It's going to rain soon.
• These figures are really bad. We're going to make a loss.
• You look very tired. You're going to need to stop soon.
We can replace 'going to go' by 'going'.
• I'm going out later.
• She's going to the exhibition tomorrow.
