Conditionals - Zero Conditionals

{A}  Zero Conditionals:

Nature:Result of the condition is always true

These sentences show the always true condition.

Note:

*We use the present simple in both clauses of the zero conditional. We are saying that the condition can be true at any time (it is a fact).

STRUCTURE:

*If + present simple, .... present simple.

*We can use If / when / whenever in a zero conditional sentence. They mean the same.

*This conditional is used when the result will always happen.

*The result of the 'if clause' is always the main cluase.

If	CONDITION	RESULT
	Present Simple	Present Simple
If	it rains	I stay at home.

Some examples:

*If you heat water to 100 degrees, it boils.

Conditionals

 Conditionals

"Condition" means "situation or circumstance". If a particular condition is true, then a particular result happens.

What Are Conditional Sentences?

* Conditional sentences play an important role in grammar. They describe a condition and the result that follows.

* Conditional sentences are also known as Conditional clauses or If clauses.

* Conditional sentences have two clauses:  a condition (if...) and a result.

* Conditionals are sentences with two clauses – an ‘if clause and a main clause – that are closely related.

* Conditional sentences are used to express that the action in the main clause (without if) can only take place if a certain condition (in the clause with if) is fulfilled.

* The clause without the if is the main clause of the sentence, while the if clause is subordinate.

******************************************************* 

Definition:-

Conditional sentences are made up of two halves -

One half (the half with the word if in) is a condition,

and the other half (the main clause) states the action to occur if the condition is fulfilled.

*******************************************************

 eg.:-

Conditional Clause and Main Clause

If I have enough money, Conditional clause	I will buy a car. Main clause
I will buy a car, Main clause	if I have enough money. Conditional clause

******************************************************

 Note:-

* The order of the two clauses is generally not that important to the meaning of the sentence; so we can switch the if clause to the end of the sentence if we want to.
