Reported speech: questions and commands

When we report questions the word order changes to the order of a statement and the auxiliary disappears: “Where do you study?” → He asked me where I studied. In yes/no questions we use if or whether: “Do you like sport?” → She asked if I liked sport. Commands use ask / tell / order + person + to-infinitive: “Close the door.” → He told me to close the door. A negative command uses not to. Time and place words change too: now → then, today → that day, tomorrow → the next day, here → there. Antonyms are words with opposite meanings: join – leave, active – passive, include – exclude, generous – mean. Some are made with prefixes: possible – impossible, polite – impolite, happy – unhappy.
