The future: Will, Be Going To, Present Continuous
· We use will when we decide to do something at the time of speaking: OK, I'll throw those away.
· We use be going to when we already have a plan or an intention to do something: I'm going to sort out the rest of them at the weekend.
· We use the Present Continuous when we have an arrangement with another person: She's picking them up tomorrow evening after work.
· We use be going to for rediction that is based on present evidence ( we predict the future because of something we can see in present): It's going to break the first time he uses it!
· We use will for a prediction that is not based on present evidence: But you'll never listen to them again.
* When we use the Present Continuous for future arrangements, we usually know exactly when the arrangements are happening. They are the kind of arrangements we can write in a diary: I'm having dinner with Richard on Saturday.
* We can also use be going to to talk about future arrangements: What are you going to do tomorrow?
· We make the positive and negative forms of will with:
subject + 'll (=will)/won't ( =will not) + infinitive
I'll do that for you.
He won't throw that away.
*Will/Won't is the same for all subjects:
I/you/he/she/it/we/they will/won't do it.
· We make quesitons with will with:
(question word) + will + subject + infinitive
When will it be here?
Will it rain at the weekend?
*We often use probably or definitely with will:
Her kids will probably/definitely like them.
*We often use might to mean 'will possibly':
I might finish it this weekend.
*We also use will to talk about future facts and for offers:
I'll be 45 next birthday. I'll help you clear out the study.
