Condisional ingles

Conditional (first, second and zero)


Conditional clauses begin with “IF” (or a word such as “when” which means the same as “if”) and follow basic patterns. This Section deals with patternswhich form the First, Second and Zero Conditionals:
 
1) First Conditional
 
We use First Conditionals to talk about events which are possible. The Conditional clause can refer to the present orthe future.
 
Conditional clause      Main clause
If+ Present Simple      will + infinitive
If it rains, we will stay at home.
 
• The Conditional clause can come before or
after the mainclause. We use a comma at the
end of the Conditional clause when it comes
first:

If you don't try harder, you will fail.
You will fail if you don't try harder.
 
• Other structures arepossible, depending on what you want to say:
