FIRST CONDITIONAL
If you study hard, you´ll pass th exam.
IF +PRESENT, WILL / WON´T + INFINITIVE
THANKS
WE USE: IF + PRESENT TO TALK ABOUT A POSSIBLE SITUATION AND WILL / WON´T + INFINITIVE TO TALK ABOUT THE CONSEQUENCE. If I save enough money, I´ll go to the beach.
We can also use the IMPERATIVE or CAN + INFINITIVE instead of WILL + INFINITIVE in the other clause. If you miss the bus, get / you can get a taxi.
If the will / won´t -clause comes first, usually there´s no comma before the next clause. We´ll build a house if my family buys the land.
The if-clause can come first or second. If the if-clause comes first, we usually put a comma before the next clause. If she passes the exam, she´ll go abroad.
