Show students the list of people, places, and things from the exercise: Michigan State University Russia Sergey’s mother Sergey’s father Larry’s parents Maryland University Wes Clark’s new book Explain: “You’ll listen to the interview once. Your task is to put these people, places, and things in the order you hear them.” “Don’t worry about understanding everything — just focus on the order.” Play the recording (Track 18) once. Students write the order individually. Ask students to compare their answers with a partner in breakout rooms (1-2 min) Check as a class and confirm answers. - use the transcript Answer Key: 1. Wes Clark’s new book 2. Russia 3. Sergey’s mother 4. Sergey’s father 5. Maryland University 6. Michigan State University 7. Larry’s parents After checking answers, tell students: “Now that you know the general story, we’ll look more closely at how the presenter and Wes Clark ask and answer questions about the past — that’s our grammar focus today: Past Simple Yes/No questions.”

Meaning Elicit from the text: Did you really write this book in twelve weeks? Did Sergey’s parents find work in the USA? Did Larry study mathematics?
