Zero Conditional

Conditionals are structures which we use when talking about possible actions and their results. The zero conditional is a form which expresses what always happens if or when a certain action takes place. 
Conditional sentences are usually made up of two parts, a conditional clause and a main clause. The conditional clause is the 'if' part of the sentence and the main clause is the result, what happens.

This the basic structure of zero conditionals.

CONDITIONAL CLAUSE		MAIN CLAUSE
If / when	present simple	present simple
If When	you heat ice, she's not in,  you don't water plants,	it melts. her machine takes a message. they die.

The two clauses can come in any order. In written English if the conditional clause comes first, you put a comma between it and the main clause. You don't use a comma if the main clause comes first. Look carefully and you can see that the previous two sentences contain two examples of the zero conditional!

The first conditional

A conditional is used to talk about a possible or imaginary situation (the condition) and the consequences(or the result) of it. 

The first conditional - meaning

We use the first conditional to talk about something that will happen (the result), if a particular condition (which is likely to happen) is met.

“If Tim works in the stockroom, he’ll get an interview”

Because the manager is asking Tim to work in the stockroom, it's likely that Tim will do it and that's why we use the first conditional here.

In order to get an interview, Tim has to work in the stockroom.

If you do this for me, you'll have a chance of promotion.

If Tim works in the stock room, he will get an interview.

If Tim doesn't work in the stock room, he won't get an interview.

So, the meaning is that if the condition is met (and it's more than 50% likely to happen) then the result will happen.

The first conditional - form

The first conditional is made up of the condition (the 'if' part of the sentence) and the consequence or the result.

If + present simple, will + base verb

If Tim works in the stockroom, he will get an interview.

If you do this for me, you'll have a chance of promotion.

The first conditional - Modal verbs will, may and might:

When we use will in the result clause of the first conditional, we are certain that something will happen. It is definite. But we can use may or might instead of will. This means that the consequence is not certain. It is possible, but not definite.

I'm not feeling very well. If it rains tomorrow, I'll stay at home.

I'm feeling fine and I've got a car. If it rains tomorrow, I might stay at home, or I may go shopping. I'll decide tomorrow.

Note: In the first conditional, there is no difference in meaning between may and might.

The first conditional - If and if not:

In conditional sentences, you don't always use 'if' or 'if not'. You can use 'provided that' or 'so long as' instead of 'if'.

For example:

If you put down the gun, I won't call the police. =

So long as you put down the gun, I won't call the police. =

Provided that you put down the gun I won't call the police. =

(Provided that is more formal than if. )

You can use 'unless' instead of 'if not'.

For example:

If you don't put the gun down, I'll call the police. =

Unless you put the gun down, I'll call the police.
