We make the first conditional with two clauses: the action clause (If clause) with the present simple and the result clause (main clause) with will.
Conditional sentences can start with the action:
If you light a fire, you'll feel warmer.
or with the result:
You'll feel warmer if you light a fire.
We can use the negative form in the action, the result, or both parts of the sentence.
We won't win the challenge if we get lost in the trees.
If he doesn't have a compass, he'll get lost.
If we don't make a big noise, we won't find help.
We make first conditional questions with will before the subject in the result clause.
Will you help me if I carry your bag?
Do you help me...?
If I carry your bag, will you help me?
If I will carry your bag...
Usage
We use the first conditional to predict the result of an action. We use it to talk about things we think might happen in the future and things we think are possible.
