( Type I: If — Present Tense — will
I If the weather's fine, we'll have a picnic.
A porter will come if you ring the bell.
The Present Tense in the if-clause refers to a possible future action.
. If the weather's fine means that it may be either fine or not. It leaves the question open ... will you really have a picnic or won't have it dеpends on the weather.
We can also use will in an if-clause when we make a request:
If you'll just wait a moment, I'll get the file.
(= Please wait a moment...)
Sometimes we can also use the Present Continuous Tense (e.g. are doing) or Present Perfect (e.g. have done) in the if-clause:
if we're having a picnic, the picnicking area will need a good * cleaning.
If you've finished packing our things, I'll put the litter into this bag. j We can use other modal verbs (e.g. can, should) in the main clause. § If you're going on a picnic, you should know the weather forecast.
