First conditional (if)


The first conditional structure is used to talk about possibility in the future - something which will or will not happen in the future depending on certain conditions being met.

"If they win the match,   I will buy them dinner."  
If this happens ...   ... this will happen.  
If this doesn't happen ...   ... this will not happen.

"If you study hard,   you will pass the exam."  

"If she sings well,   she will win the competition."  


A first conditional sentence contains two clauses: the "if" clause and the main clause.

To make the "if" clause, we use:
"if" + present tense.

To make the main clause, we use:
future tense.

The "if" clause can be used first or second. The meaning is exactly the same:
When the "if" clause is used first there is a comma between the clauses.

We can use "when" in place of "if":
For example:
