FIRST CONDITIONAL

We can use the first conditional to talk about the result of a possible event or situation in the future.

The if clause talks about things that are possible, but not certain

We make the first conditional with:

If + Present Simple, will/won’t + infinitive

The if clause can be first or second in the sentence:

I’ll be exhausted after a year if I start teaching again.

We often use might in the main clause to mean ‘will perhaps’:

“But you might have to wait until next year if you don’t apply soon”

We can use unless to mean ‘if not’ un the first conditional:

“Unless I do it now, I’ll be too old” = if I don’t do it now, I’ll be too old
