This document defines and explains the different types of conditional sentences in English: - Conditional sentences express conditions that are necessary for something to happen, using linkers like "if" and verbs like "will" or "would" to indicate probability. - There are three types of conditionals: first, second, and third. The structure is the same but the tense changes to imply different levels of probability. - First conditionals use the present simple and "will" to express a high possibility. Second conditionals use the past simple and "would" for less possibility. Third conditionals use the past perfect and "would have" for impossible conditions.

They act like two separate boxes, you
can change their order, but never mix
them: You will pass, if you study.Never
say: *if you will ….

4. WHAT ARE THEY FOR…?
• THEY EXPRESS CONDITION, THAT IS, THE
PROBABILITY FOR SOMETHING TO HAPPEN.
• HOW? BY USING LINKERS, AND MODAL VERBS (will
would) WHICH EXPRESS PROBABILITY.
• THERE ARE 3 TYPES: first, second and third
• The structure is the same, but second and third
conditionals imply a past tense because, as you know, in
English, using a past/more remote tense, expresses less
possibility.
