Conditional in English

Three Conditionals in English:
1
First Conditional
This conditional is used to talk about future events that might happen. It uses the present tense to discuss the possible future events. For example:
If it rains, we will have to cancel the picnic. ...
If you come with me, I will make it worthwhile for you.
2
Second Conditional
This conditional is used to talk about unreal possibility or impossible events. They establish the course of action that would follow, where something to happen is either hypothetical or surreal.. For example:
If I had a million dollars, I would buy a penthouse on Park Avenue.
I could stop working if I won the lottery.

Third Conditional
This conditionals talks about the past, unlike the first and second which discusses events in the real or unreal future. These conditions, too, are therefore impossible, because they have either already occurred or might have occurred but won’t anymore. For example:
If I had studied a little more in college, life would have been easier.
If we had gotten to the airport on time, we would have caught our flight.
