This document discusses the second conditional, which is used to talk about unreal or hypothetical situations. It provides examples of sentences using the second conditional structure of "if + past simple, would + verb". Some key points made are:
- The second conditional uses past tense verbs to talk about unlikely or imaginary situations.
- Examples given include "If I were rich, I would travel around the world" and "I would buy a new house if I won the lottery."
- It explains that the if-clause can come first or second in a sentence without changing the meaning.
