Primer y Segundo Condicional En Ingles

FIRST CONDITIONAL
Introduction
The first conditional (also called conditional type 1) is a structure used for talking about possibilities in the present or in the future. This page will explain how the first conditional is formed, and when to use it.
1. The structure of a first conditional sentence
A first conditional sentence consists of two clauses, an "if" clause and a main clause:
|ifclause |main clause |
|If you study hard, |you will pass the test. |

If the "if" clause comes first, a comma is usually used. If the "if" clause comes second, there is no need for a comma:
|main clause|if clause |
|you will pass the test |if you study hard. |

We use different verb forms in each part of a first conditional:
|if clause |main clause|
|Simple present |Will + base form of the verb |
|If you study hard, |you will pass the test. |

2. Using the first conditional
The first conditional is used totalk about things which are possible in the present or the future — things which may happen:
|Example |Explanation |
|If it's sunny, we'll go to the park. |Maybe it will be sunny — that's possible. |
|Paula will be sad if Juan leaves.|Maybe Juan will leave — that's possible. |
|If you cook the supper, I'll wash the dishes. |Maybe you will cook the supper — that's possible. |

First Conditional: real possibility

We are talking about the future. We are thinking about a particular condition or situation in the future, and the result of this condition.There is a real possibility that this condition will happen. For example, it is morning. You are at home. You plan to play tennis this afternoon. But there are some clouds in the sky. Imagine that it rains. What will you do?

|IF |Condition |Result |
| |present simple |WILL + base verb |
|If |it rains|I will stay at home. |

Notice that we are thinking about a future condition. It is not raining yet. But the sky is cloudy and you think that it could rain. We use the present simple tense to talk about the possible future condition. We use WILL + base verb to talk about the possible future result. The important thing about the first conditional is that there is a real possibilitythat the condition will happen. Here are some more examples (do you remember the two basic structures: [IF condition result] and [result IF condition]?):

|IF |Condition |Result |
| |present simple |WILL + base verb |
|If |I see Mary,|I will tell her. |
|If |Tara is free tomorrow, |he will invite her. |
|If |they do not pass their exam, |their teacher will be sad. |
|If |it rains tomorrow, |will you stay at home? |
|If |it rains tomorrow, |What will you do?...
