“DO YOU REMEMBER” is about a relationship that ended. It makes us wonder what happened, so it´s a good song to practice Past Modals of Speculation. First, students say whether they agree or not with a quote about relationships. Then, they rank reasons for a couple to break up and share them in pairs. Next, they listen to the song and try to find out what caused the couple to break up. Finally, they write at least three possible reasons using the structure suggested.
