Hi everybody,
When do you use ( to be + past
ex : Many people have to be traced.
Is it for something that must be done in the future?
have to ( be + pp ) and also (for something to be pp )
Is it correct ?
thank you a lot.

Hello,
Yes you are right. 'Have to' stands for 'must' in the present tense.
The windows have to be cleaned = the windows must be cleaned.
...........will have to be cleaned. (using 'must' is impossible)
...........had to be cleaned. (using 'must' would be confusing)
Regards.
