Hello,

there are some differents.

have to is used by laws.
Example: Dogs have to wait outside.

must is used if you want to do something. It's not a law.
Example: I must ask Julia out today.

need to is used, if you need something.
Example: I need a new television.
needn't is the opposide of must.
Example: I needn't ask Julia out today.

supposed to is used, if you guess something.
Example: I suppose so. (like: I think so.)

should is used, if you want to say, that it is better to do something.
Example: If you are ill, you should go to the doctor.


I hope this helps.

Kind regards,
Dany

I am the one who asked the question. I forgot to log on sorry.

1. I need to do my homework.
2. I am supposed to do my homework.
3. I have to do my homework.
4. I must do my homework.
5. I should do my homework.

If have to is used by law and must is not, then what about the rest?
