Conditional 1
Often called the "real" conditional because it
is used for real - or possible - situations.
These situations take place if a certain
condition is met.

He will arrive late unless he hurries up.
Peter will buy a new car, if he gets his raise.
NOTE
In the conditional 1 we often use unless which

he hurries up.' could also be written, '...if he
doesn't hurry up.'.
