The document discusses the second conditional, which is a grammatical structure used to talk about improbable or hypothetical situations and their consequences. It uses "if" clauses with past tense verbs followed by main clauses with "would" expressing what might happen. Examples are provided such as "If I won the lottery, I would buy a big house" and "I would go on a trip if I had more money." The structure and examples demonstrate how to express what someone would do if some unlikely event occurred.
