What is the second conditional?:Explanation and examples.

There are two parts to a conditional sentence: the if-clause and the result-clause. 
The 2nd (second) conditional sentence structure is called the present unreal conditional or hypothetical conditional.
You can also use this sentence structure to imagine a situation that is unlikely or impossible in the present.
