This document discusses conditional sentences in English grammar. There are three types of conditional sentences: real conditional (type 1), unreal conditional (type 2), and unreal past conditional (type 3). Type 1 uses present tense to talk about possible future events. Type 2 uses past tense to talk about improbable or impossible events. Type 3 uses past perfect tense to talk about regrets or imaginary past situations. The document provides examples and explanations of how to form each type of conditional sentence in English.
