have to / must

[Dany]

Hello together,

I have a little question. At time I learn english in an old practice book of my schooltime. Among other things there is a cloze where I have to fill "have to", "have not to", "must" and "must not". I don't know when I have to make "have to" or "must".

Example:
My doctor says I ______ smoke. It´s better for the health.

I took "have not to" but my book says, I have to take "must not".

Could you please explain me, why I have to take "must not" ?
Please correct my mistakes.

Thanks a lot.

1a. The doctor says I must not smoke.
(It's strongly recommended that you quit smoking)

1b. The doctor says I don't have to smoke if I don't want to smoke. (You have a choice. 'don't have to' means, not necessary)

for a site on Modals and their meanings. :D

Hello everyone,

I have a little question. At this time I am learning English from an old practice book I used when I was in school. Among other things there is a cloze exercise where I have to fill in "have to", "have not to", "must" and "must not". I don't know when to use "have to" or "must".

Example:
My doctor says I ______ smoke. It´s better for the health.

I chose "have not to" but my book says the answer is "must not".

Could you please explain to me why I have to choose "must not"?

Oh, there are really a lot of mistakes

I must admit that I have nothing done for my English for seven years. I have forgotten a lot since that term. Today I'm sorry about it.

Thanks for your corrects :D

'I must admit that I have done nothing about my English for the last seven years. I have forgotten a lot since then. Today, I feel sorry about it.

Thanks for your corrections' lol:

To get back to your original question, Dany, 'have not to', or more commonly 'haven't to', is an older form of 'don't have to'.
