Conditional 1 (zero, first, second)
INTRODUCTION TO CONDITIONAL
Some sentences with the word ‘if’ are called conditional sentences.
With every conditional sentence, there are two parts: a situation and the result of that
situation. It is the situation that starts with ‘if’.
There are different types of conditional sentence, depending on what the situation is.
Helpful hints
When we start the sentence with ‘if’, we separate the situation and the result with a
comma.
If you join a gym, I’ll join too.
When we start the sentence with the result, we don’t use a comma.
I’ll join too if you join a gym.
