The document discusses how to change direct speech into reported or indirect speech. It states that verbs in reported speech are usually changed to the past tense since one is referring to something said in the past. It provides examples of changing basic verb tenses like simple present to simple past. It also discusses changing modal verbs like "can" to "could" and questions to indirect questions or using if/whether. The goal is to concisely summarize how reported speech works at a high level.
