Talking about the future in English can be confusing!
We use “will”, “shall”, “be going to” and “the Present Continuous” for different reasons when we talk about the future.
Will / Shall + infinitive
We use “will”, “shall” for:
-instant decisions at the time of speaking.
Example:
I’ll have the steak.
– promises
Example:
I won’t tell anybody your secret
– offers
Example:
I’ll pick you up at seven.
– predictions (without present evidence)
Example:
You’ll never come back to live here.
– suggestions
Example:
Shall we see a movie tonight?
NB: Use shall (NOT will) with “I” and “we” for offers and suggestions when they are questions.
We also use “will” for future facts.
Example:
I’ll be forty this year!
Be going to + infinitive
We use going to for:
– planned actions that we have already decided to do before the time of speaking.
Examples:
We’re going to get married next year.
I’m going to play football on Saturday.
– predictions based on present evidence.
Examples:
Look at those black clouds! It’s going to rain.
We’ve missed the train! We’re going to be late.
NB: With the word go you can leave out the infinitive.
Example:
I’m going to go to Switzerland. —> I’m going to Switzerland.
Present Continuous
We can use “going to” or “Present Continuous” for future plans.
– “going to” shows you have made a decision.
Example:
We’re going to get married in the spring.
– “Present Continuous” emphasizes that you have made the arrangements.
Example:
We’re getting married on May 5th.
NB: We usually use Present Continuous when we have made an arrangement with another person. They are the kind of arrangements you would write in a diary.
Examples:
I’m seeing the doctor at 2pm tomorrow. ( I have an appointment)
I’m meeting Anna for breakfast on Saturday. ( I ‘ve made an arrangement with Anna)
NB: We can always use “going to” instead of “Present Continuous”.
