Listen and read the dialogue. What does Sue want to protect? (Nghe và đọc đoạn hội thoại. Sue muốn bảo vệ cái gì?)
Sue: I visited the castle yesterday. It’s so beautiful, but no one looks after it. What can we do to protect it?
Ben: My advice is not to take souvenirs, like pieces of stone, from the castle.
Sue: Good point. Is there anything else I can do?
Ben: Well, have you thought about wearing flat shoes with soft soles when you visit? That way, you won’t damage the stones.
Sue: That’s good thinking. Thanks!
