Technically 'have to' is only a substitute modal but the construction may have to is fine. Note also: I ought to be able to where able to is doing the same job as have to.

>>I may ...have to...... go to Paris next week because there is a very big exhibition there.

Two things I did not understand here.

1. why "have to" is the correct answer. I think it is not compulsion that I have to go to exhibition.

2. I confused in usage of "there" two times. Is this a correct usage in "...because there is a very big exhibition there"

BTW, I scored 9 because of this que.

Thanks,
Paresh

Hi,

'May' qualifies 'have to' suggesting it may be necessary with the idea that it's not definite. 'There' is used in two capacities. In 'there is' we are talking about something exists as in' there is a big exhibition'. In the final 'there' we are using it as an adverb of place = in that place.

Hi,
Can you explain me the exact meaning of the expression "may have to do something"? In our context, is something like it is possible to have to go to Paris?
Thank you,
