This document provides examples and explanations of how to use the second conditional to talk about unlikely or imaginary situations. The second conditional uses the structure "if + past tense, would + base verb" to talk about situations that are unlikely or impossible. Examples are given such as "If I won the lottery, I would travel around the world" to demonstrate talking about unlikely present or future situations. Other modal verbs like "could" and "might" can also be used instead of "would". Exercises are provided to practice forming second conditional sentences.
