HI bea,
Why 'must' in #5? Isn't it necessity imposed by the circumstances? Also an action against one's will?

sorry, Clark , I was so overcome by the word "overcome" I simply overlooked this
(which is simply unacceptable for anyone in our profession , I know )
still , I'll pay more attention from now on -cross my heart and hope to die

If you think it really helps, I'll do the same.

[B]have to or must

2-you mustn't drive fast;there is speed limit here.

Or, "can't drive fast here; there is a speed limit". can't = not allowed to. <mustn't> sounds odd for NaE, like it's a personal admonishment. I'd say that <can't> would be a more natural choice.


4-waiters have to/must pay tax on the tips that they receive.

Using 'must' makes it sound more official and that likely would be the choice in regulations/tax info in a formal written sense. 'have to' is definitely the more common choice for speech.

5-in my district there is no gas [laid on]. People must use electricity for everything.

'have to' is definitely the more common choice for speech but 'must' is a possibility.

might or may

1-warning:no part of this book might he reproduced without the publisher's permission.

'might' is also used for permission but not for the sense of prohibition.


3-Two parallel white lines in the middle of the road mean that youmay not [overcome] pass.

I think that for NaE, the tendency would be to use <can't/not allowed to> here.



could or be able to or can

1-I was able to/could do it when I was [at] in school but I couldn't/can't now.

Both <can't> and <couldn't> would work here. The former looks to a greater reality, for example, maybe someone is challenging you to try it now. The latter speaks more to a theoretical sense, the speaker is saying that such an idea is not even being entertained.


2-when the fog lifts we can/will be able tosee where we are.

Both <can> and <will be able to> seem to be possible.
