听力原文：M: May I help you? W: Yes, I want to buy some shoes to replace the ones I'm wearing. M: What's wrong with them? W: They are too old and shabby. M: I can see they have simply been worn out. Would you like the same color, more or less? W: Yes, and something a little less casual. M: How about this light yellow pair? They are similar to what you wear, but a little bit dressier. W: Yes, I was thinking of something along that line. I'll try them on. M: They certainly look charming. W: The trouble is, they feel a little uncomfortable. M: Then try on this other pair in a similar style, but by a different manufacturer. W: These are much better. Do you have them in dark red? M: Yes. Would you like both pairs? W: Yes, if they won't cost toe much. M: Oh no, they won't. The second pair is half price. Shall I put them both in a box for you? W: Just the dark red. And the old ones. I'll wear the new light yellow pair home. What was wrong with the first pair the woman tried on?
