The document discusses the rules for changing direct speech into reported or indirect speech. It explains that verbs shift to the past tense in reported statements. Modal verbs like "can" and "will" change to "could" and "would". Questions become statements in reported speech and wh- questions do not change word order. Commands are reported using "tell" plus the infinitive. Words referring to specific times and places like "now", "here", and "today" change to more general terms like "then", "there", and "that day" in reported speech.
