Look at this sentence.
“I told George and Harris that they had better leave the whole matter entirely to me.”
The words had better are used
• in an advice or suggestion:
You had better take your umbrella; it looks like rain.
• in an order
You had better complete your homework before you go out to play.
• as a threat
You had better leave or I’ll have you arrested for trespass!
When we speak, we say you’d/I’d/he’d better, instead of you had better, etc.
Work in pairs to give each other advice, orders or suggestions, or even to threaten each other. Imagine situations like the following: Your partner
1. hasn’t returned a book to the library.
2. has forgotten to bring lunch.
3. hasn’t got enough change for bus fare.
4. has found out a secret about you.
5. has misplaced your English textbook.
