Grammar:

FIRST CONDITIONAL
-Use if + present, will + infinitive to talk about possibles future situation and its consequence.
-The if clause can come first or second: I'll come if you like OR If you like, I'll come.

-She wont'be angry if you tell her the truth.
-What will you do if it rains?

SECOND CONDITIONAL
-Use if + past, would + infinitie to talk about an improbable/impossible or hypothetical future situation and its consequence.
-Would/Wouldn't is the same for all people.
-The contraction of would is 'd (I'd, you'd, he'd, etc.)and of would not is wouldn't.
EXAMPLES:
-If a beard attacked me, I'd run away.
-If I didn't have children, I wouldn't live in the country.
-Would you take the manager's job if they offered it to you?

THIRD CONDITIONAL:no possibility

The first conditional and second conditionals talk about the future. With the third conditional we talk about the past. We talk about a condition in the past that did not happen. That is why there is no possibility for this condition. The third conditional is also like a dream, but with no possibility of the dream coming true.
-Last week you bought a lottery ticket. But you did not win.

	Condition	Result
	Past Perfect	WOULD HAVE + Past Participle
If	I had won the lottery	I would have bought a car.
