Zero Conditional: certainty

We use the so-called zero conditional when the result of the condition is always true, like a scientific fact.

Take some ice. Put it in a saucepan. Heat the saucepan. What happens? The ice melts (it becomes water). You would be surprised if it did not.

IF	Condition	Result
	present simple	present simple
If	you heat ice	it melts.

 

 

Notice that we are thinking about a result that is always true for this condition. The result of the condition is an absolute certainty. We are not thinking about the future or the past, or even the present. We are thinking about a simple fact. We use the present simple tense to talk about the condition. We also use the present simple tense to talk about the result. The important thing about the zero conditional is that the condition always has the same result.

We can also use when instead of if, for example: When I get up late I miss my bus.

Look at some more examples in the tables below:

IF	Condition	Result
	present simple	present simple
If	I miss the 8 o'clock bus	I am late for work.
If	I am late for work	my boss gets angry.
If	people don't eat	they get hungry.
If	you heat ice	does it melt?

 

Result	IF	Condition
present simple		present simple
I am late for work	if	I miss the 8 o'clock bus.
My boss gets angry	if	I am late for work.
People get hungry	if	they don't eat.
Does ice melt	if	you heat it?

 

 

First Conditional: real possibility

We are talking about the future. We are thinking about a particular condition or situation in the future, and the result of this condition. There is a real possibility that this condition will happen. For example, it is morning. You are at home. You plan to play tennis this afternoon. But there are some clouds in the sky. Imagine that it rains. What will you do?

IF	Condition	Result
	present simple	WILL + base verb
If	it rains	I will stay at home.

 

Notice that we are thinking about a future condition. It is not raining yet. But the sky is cloudy and you think that it could rain. We use the present simple tense to talk about the possible future condition. We use WILL + base verb to talk about the possible future result. The important thing about the first conditional is that there is a real possibility that the condition will happen. Here are some more examples (do you remember the two basic structures: [IF condition result] and [result IF condition]?):

IF	Condition	Result
	present simple	WILL + base verb
If	I see Mary	I will tell her.
If	Tara is free tomorrow	he will invite her.
If	they do not pass their exam	their teacher will be sad.
If	it rains tomorrow	will you stay at home?
If	it rains tomorrow	what will you do?

 

Result	IF	Condition
WILL + base verb		present simple
I will tell Mary	if	I see her.
He will invite Tara	if	she is free tomorrow.
Their teacher will be sad	if	they do not pass their exam.
Will you stay at home	if	it rains tomorrow?
What will you do	if	it rains tomorrow?
