如何退换羊毛衫？退换商品时有什么规定
 
来听今天的讲解:
 
A: Hello, I'd like to return this woolen sweater.
 
你好，我想退还这件羊毛衫。
 
B: Do you have the receipt?
 
您有收据吗？
 
A:Yes, it's in a box.
 
有，在盒子里。
 
B: Would you like to try on a larger size?
 
您想试穿大一号的吗？
 
A: No, thanks. I just want my money back.
 
不了，谢谢，我只想把钱拿回来。
 
B: We don't provide refunds, although I'll be happy to exchange your purchase.
 
我们不退款，不过我很乐意更换您的商品。
 
A: If that's the case, can I try on a different style, please?
 
若是如此，请问我可以试穿不同的款式吗？
 
B: Items can only be exchanged for those of the same style.
 
只有相同款式的商品才可以更换。
 
A: I don't want the same style. Not only were the arms too tight, but the body was too baggy. If I get a larger size, the arms might be alright, but the body will be even looser.
 
我不想要相同的款式衣服，不仅袖子太窄，而且衣身太宽松。如果我拿大一号的，袖子或许没问题，但衣身会更松垮。
 
B: In light of the fact that your expectations were not met, I'll bend the rules and give you a full refund.
 
先生，由于您的期望落空，我这就放宽规定，给您全额退款。
