(Be) supposed to
Sometimes (
it is)
supposed to ... = (it is) said to ... :
- I want to see that film. It's supposed to be good. (= it is said to be good)
- Fireworks are supposed to have been invented in China. Is it true?
But sometimes
supposed to has a different meaning. We use
supposed to to say what is intended, arranged or expected. Often this is different from the real situation:
- The plan is supposed to be a secret, but everybody seems to know about it. (= the plan is intended to be a secret)
- What are you doing at work? You're supposed to be on holiday. (= you arranged to be on holiday)
- Our guests were supposed to come at 7.30, but they were late.
- Jane was supposed to phone me last night, but she didn't.
- I'd better hurry. I'm supposed to be meeting Chris in ten minutes.
You're
not supposed to do something = it is not allowed or advisable:
- You're not supposed to park your car here. It's private parking only.
- Jeff is much better after his illness, but he's still not supposed to do any heavy work.
