CONDITIONAL 0

USE, EXAMPLES AND EXERCISES

Thursday 18 September 2014Colegio Andino 2

Conditionals have two parts: An if clause and a main clause.

When the if clause comes first, we use a comma between the two clauses. When the main clause comes first, we don't use a comma.

Remember!!!


Example:

main clause If clausePerson+ verb+If +person+verb+complement

it breaks If you drop an egg.

If clause main clause If +person+verb+complement+ , +person+ verb

If you drop an egg , it breaks.


The zero conditional is used:

a) for instructions:

If you select reverse gear, the car goes backwards. If the camera is on, a red light appears.

How to use the 0 Conditional?


b) for general truths:

If he has no money, he doesn't go out. Linn always says hello when / if he sees you.

* If has the same meaning as when here*


In both, if clause and main clause, we use the Present Simple Tense.

And it expresses facts that are always true


Form:if + present simple present simple

If you press the button, the machine switches off.

or present simple if + present simple

The machine switches off if you press this button.


She doesn't get some money If she doesn't work hard

Present simple negative sentence

In this case we use the negative auxiliaries of Present simple tense don't or doesn't + infinitive verb.
