Type I Conditionals
IF + ACTION , CONSEQUENCE
IF + PRESENT SIMPLE , WILL + INF
Type I (First) Conditionals are often described as being formed of If + Present Simple, Future Simple. The future simple does not exist as a tense, Will is a modal verb and is always followed by an infinitive.
We use Type I (First) Conditionals to talk about:
A consequence that is not inevitable but highly likely or probable
A supposition, a prediction.

I will get wet if it rains
NOTE: Type I conditionals are often used incorrectly to provide the same function as a Type 0. Remember Type 0 Conditionals express an inevitable truth, a Type I is a predicition of of a probable future consequence of an action.
