Conditionals
Grammar explanation
Conditionals describe the result of a certain condition. The if clause tells you the condition (If you study hard) and the main clause tells you the result (you will pass your exams). The order of the clauses does not change the meaning.
Conditional sentences are often divided into different types.
Zero conditional
We use the zero conditional to talk about things that are generally true, especially for laws and rules.
The structure is: if/when + present simple >> present simple.
First conditional
We use the first conditional when we talk about future situations we believe are real or possible.
In first conditional sentences, the structure is usually: if/when + present simple >> will + infinitive.
It is also common to use this structure with unless, as long as, as soon as or in case instead of if.
Second conditional
The second conditional is used to imagine present or future situations that are impossible or unlikely in reality.
The structure is usually: if + past simple >> + would + infinitive.
When if is followed by the verb be, it is grammatically correct to say if I were, if he were, if she were and if it were. However, it is also common to hear these structures with was, especially in the he/she form.
