Conditional Sentences, If Causes Type 0,1,2,3

Before we know the types of conditional sentences, we first recognize their composition:

The conditional sentence consists of two sentences linked to the If :

If-clause and main clause

- Examples :

👉 It is easier to relax, if you close your eyes .

If-clause : It is easier to relax if,

Main clause : You close your eyes .

- There are four cases of if-clause:

>>>  Zero Conditional

>>>  Conditional Type 1

>>>  Conditional Type 2

>>>  Conditional Type 3

1- Zero Conditional in English:

 A- Uses Zero Conditional : a fact something that is always true .

B- Formulation : If +Present Simple = Present Simple

- Example :

👉 If you touch a fire, you get burned.

If-clause : If you touch a fire,

Main clause : You get burned .

2-  Zero Conditional Examples:
