听力原文：W: Oh, no! Oh, I can't believe I dropped that mirror. What bad luck.

M: Don't worry, mama! I'll pick it up for you.

W: Thanks. But you know I can just hear your grandmother's voice saying" Now you are in for seven years of bad luck. ".

M: Why would she say that？

W: Oh, you know her, she's very superstitious. She believes that once a mirror is broken, you can't see yourself as a whole person in it. So something really had is going to happen to you.

M: Yes, but why？ Why seven years of bad luck.

W: Well, I guess a long time ago, people thought it took seven years for the body to repair itself, so I guess it would take seven years to fix a broken body.

M: Seven years is a really long time. I guess I’m glad I didn't drop that mirror.

W: Oh？

M: No, mama, I'm only kidding. I mean you don't really believe in that stuff, do you？
