ZERO CONDITIONAL
The "zero conditional" is used when the time referred to is now or always and the situation is real and possible. This type of conditional is usually used to talk about general facts. The verb tense of both propositions is the "simple present". In conditional type 0 sentences, the term "if" can usually be replaced by "when" without changing the meaning.
FIRST CONDITIONAL
The "type 1 conditional" is used to refer to the present or future when the situation is real. Conditional type 1 refers to a possible condition and its probable outcome. In these sentences, the "if" clause adopts the "simple present" and the main proposition the "simple future".
SECOND CONDITIONAL
The "type 2 conditional" is used to refer to a time that can be now or at any time and a situation that is not real. These prayers do not allude to facts. The conditional type 2 is used to refer to a hypothetical condition and its probable outcome. In these sentences, the "if" proposition adopts the "simple past" and the main clause the "present conditional".
THIRD CONDITIONAL
The "type 3 conditional" is used to refer to a time in the past and a situation contrary to reality. It is based on facts that are opposed to what is being expressed. The conditional type 3 is used to refer to a condition of the past that is not real, as well as to its probable outcome in the past. In these sentences, the "if" clause adopts the "past perfect" and the main proposition the"perfect conditional"
