- I may / might help you if you ask nicely. = I will possibly help…
- He should / ought to be here any minute now. = From what I know, I expect him to be here…
- Shall I / we lend you a hand? = Let me / us…
- Shall we say 3 o’clock? = Let’s meet / get in touch / start etc at 3.
- Sorry, I cannot see her tonight.
- You must do something about it as soon as possible.
- We have to leave in 5 minutes.
- They are to arrive at no later than 6.
- She really needs to be at work next week.
- I’d better (had better) not take the day off tomorrow.
- We’d rather (would rather) not explain ourselves, not ever.
