DIALOGUE 41

In a Department Store

1--Yes, madam. Can I help you?
2--Yes, please. Yesterday my daughter bought this
   skirt from this shop. I'd like to change it. Here,
   I've got the receipt.
1--What's the problem?
2--I'm afraid it doesn't fit. It's a size 12 and it's
   too small.
1--Mm. Then perhaps you ought to try a size 14.

注解：
