If you need any help, please let me know.
We'll enjoy our holiday unless it rains all the time.
If the sun's shining tomorrow, we'll go swimming.
When I'm on holiday I like to relax more than be active.
I'll be arriving on Sunday unless there's a change of plan.
I'll go to Rio for the Carnival if I can afford it.
Unless there's more snow on the mountains, we can't go skiing.
I'll take a couple of days off if the weather is better in April.
