What is the first conditional?
We use the first conditional when we want to describe a situation that is true if the condition is true.
The first conditional describes a REAL situation.
If Eric passes his exam, he will be very happy.
If you don’t hurry, we will be late!
We use the Simple Present for the condition and the Future (usually with will) for the result.
FORM:
If + simple present, future w/will + complement
Future w/will + complement if + simple present
NOTE: When the condition clause comes first, we use a comma before the result.
EXAMPLE:
If you stay awake late, you’ll be tired tomorrow.
Alan won’t win the lottery if he doesn’t buy a ticket.
If it rains tomorrow, I’ll take my umbrella.
