Unit 24. will/ shall (2)
See Unit 23 will/ shall (1)
You can use I'll… (= I will) when you offer or decide to do something:
- "My case is very heavy." "I'll carry it for you."
- "I'll phone you tomorrow, okay?" "Okay, goodbye."
We often say I think I'll/ I don't think I'll… when we decide to do something:
- I'm tired. I think I'll go to bed early tonight.
- It's a nice day. I think I'll sit in the garden.
- It's raining. I don't think I'll go out.
Don't use the Present Simple (I go/ I phone etc.) in sentences like these:
- I'll phone you tomorrow, okay? (not I phone you)
- I think I'll go to bed early. (not I go to bed)
Don't use I'll… for something you decided before (see Unit 21 What are you doing tomorrow? (Present for the future)):
- I'm working tomorrow. (not I'll work)
- I'm going to watch TV tonight. (not I'll watch)
- What are you doing at the weekend? (not what will you do)
Shall I …? / Shall we …?
Shall I / Shall we …? = Do you think this is a good thing to do? Do you think this is a good idea?
- It's warm in this room. Shall I open the window?
- "Shall I phone you this evening?" "Yes, please."
- I'm going to a party tonight. What shall I wear?
- It's a nice day. Shall we go for a walk?
- Where shall we go for our holidays this year?
- "Let's go out this evening." "Okay, what time shall we meet?" (Let's see Unit 48 I want you to …/ I told you to …)
