First conditional sentences are used to talk about future things which might happen that we believe are real and possible.
Example:
“If it doesn’t rain tomorrow, I’ll go to the park.”
First conditional sentences are made up of an ‘if clause’ and a ‘main clause’. The ‘if clause’ has the present simple tense. The ‘main clause’ has the future simple tense with will.
Example:
“If it doesn’t rain tomorrow, I’ll go to the park.”
