Unit 6. Will. Part one.
We use will (‘ll)
when we decide to do something at the time of speaking:
Oh, I left the door open. I’ll go and shut it.
“What would you like to drink?” “I’ll have some coffee, please.”
“Did you call Ann?” “Oh no, I forgot. I’ll do it now.”
I’m too tired to walk home. I think I’ll take a taxi. You cannot use the simple present (I do) in these sentences.
I’ll go and shut it. (not I go and shut it)
Do not use will to say what someone has already decided to do or arranged to do:
I can’t meet you tomorrow because my parents are coming to see me. (not my parents will come)
The negative of will is won’t (or will not):
Receptionist: I’m afraid Mr. Wood can’t see you until 4:00.
You: Oh, in that case I won’t wait.
We often use I think I’ll… or I don’t think I’ll… when we decide to do something:
I think I’ll stay home this evening.
I don’t think I’ll go out tonight. I’m too tired.
We often use will in these situations:
Offering to do something:
That bag looks heavy. I’ll help you with it. (not I help)
“I need some money.” “Don’t worry. I’ll lend you some.”
Agreeing or refusing to do something:
A: You know that book I lent you? Can I have it back?
B: Of course. I’ll bring it back this afternoon, (not I bring)
I’ve asked John to help me, but he won’t.
The car won’t start. ( = the car “refuses” to start)
Promising to do something:
Thank you for lending me the money. I’ll pay you back on Friday. (not I pay)
I won’t tell Tom what you said. I promise.
I promise I’ll call you as soon as I arrive.
Asking someone to do something (Will you…?):
Will you shut the door, please?
Will you please be quiet? I’m trying to concentrate.
