an expression "have time" in Present Cont.

TyndraI thought that "have time" can be used only in Pres. Simple.

No. why should you think that?

When 'have' has a stative meaning similar to 'possess' it is normally not used in the progressive/continuous. However, when it has a more dynamic meaning such as 'experience', 'take', 'consume', etc, then progressive forms are common:

Emma is having a bath.
I was having breakfast when the phone rang.
We've been having a wonderful time here.

I know that "have dinner", "have a shower", "have a rest", "have a drink" and some others can be used in continuous, but my previous teacher told me that there are two exceptions - "have time" and "have (a) cold". And now I suppose that my teacher was wrong and I learnt it wrong. There is no exception to this rule, is there?

"To have /a hard time/a good time/the time of my life/etc." is not the same idiom as "to have time." "To have time" means "to have enough time available for something." I can't exactly explain why, but it works a bit differently, and I think tht's part of the confusion here.

Could you give me examples in sentences? Maybe it could help me. Now I think it is getting clear to me gradually ...But I still need elucidation of the rule, as you said there is a difference between "to have a hard time" and "to have time". So, can the expression "to have time" also be used in continuous?

So, can the expression "to have time" also be used in continuous?

I don't think so. Let's see:

I'm not having a good time. Let's leave.

Oh, now I see!!! Thank you very much! Your answer was very helpful!

Great -- glad to help. I can't always explain the grammar rules, but I can tell you what "sounds right" and what doesn't.
