CONDITIONAL SENTENCES

THE FIRST CONDITIONAL SENTENCE
The first conditional (also called conditional type 1) is a structure used for talking about possibilities in the present or in the future.
A first conditional sentence consists of two clauses, an "if" clause and a main clause:
IF CLAUSE                                 MAIN CLAUSE
If you study hard,                  you will pass the exam

If the "if" clause comes first, a comma is usually used. If the "if" clause comes second, there is no need for a comma:

MAIN CLAUSE                            IF CLAUSE
You will pass the exam           if you study hard

The first conditional is used to talk about things which are possible in the present or the future — things which may happen:
EXAMPLE:
IF IT'S SUNNY, WE'LL GO TO THE BEACH- maybe it'll be sunny. There is a possibility.
I'LL DO THE WASHING UP IF YOU COOK THE DINNER- maybe you'll cook the dinner. There is a possibility.

DO SOME EXERCISES:
- Choose the right form of the verb
- Fill the gaps with the right verb
- Complete the gaps

THE SECOND CONDITIONAL SENTENCE
Like a first conditional, a second conditional sentence consists of two clauses, an "if" clause and a main clause:

IF CLAUSE                    MAIN CLAUSE
IF I HAD A PLANE,      I WOULD TRAVEL AROUND THE WORLD

If the "if" clause comes first, a comma is usually used. If the "if" clause comes second, there is no need for a comma:

MAIN CLAUSE                                                IF CLAUSE
I WOULD TRAVEL AROUND THE WORLD   IF I HAD A PLANE

The second conditional is used to talk about things which are unreal (not true or not possible) in the present or the future -- things which don't or won't happen:
EXAMPLES:
IF I WERE YOU, I'D GO TO THE DOCTOR- I'm not you. This is unreal.
I'D BUY A HOUSE IF I HAD A LOT OF MONEY- It's not going to happen that I'm going to have a lot of money.
