This document discusses unreal conditional sentences in English. It provides examples of things different people would do if they won the lottery and explains that these sentences use the past tense form of verbs after "if" to talk about imagined or hypothetical situations, not past events. It highlights how to form these sentences and notes that "were" should be used instead of "was" in formal contexts for all subjects when using the past tense of "be" in the conditional clause. Finally, it poses hypothetical scenarios and invites the reader to share what they would do in each case.
