In relation to another noun, the word than is necessary.

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

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.

Examples :

If you heat ice it metls.

I am late for workifI miss the 8 o'clock bus.

My boss gets angryifI am late for work.

People get hungryifthey don't eat.

Does ice melt if you heat it?

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.

Examples :

If I see MaryI will tell her.

If Tara is free tomorrowhe will invite her.

If they do not pass their examtheir teacher will be sad.

If it rains tomorrowwill you stay at home?

If it rains tomorrowwhat will you do?

The second conditional is like the first conditional.

We are

still thinking about the future.

We are thinking about a particular

condition in the future, and the result of this condition.

But there is not a real possibility that this condition will happen.

Examples :

I would be happy if I married Mary.

She would marry Ram if he became rich.

Would you be surprised if it snowed next July?

What would you do if it snowed next July?
