A: What can I do for you, sir?
B: Yes, could I have a look at dress in the showcase? I'm looking for a gift for my wife.
A: Sure. Do you know what size your wife wears?
B: I don't have her measurements, but I think it is too large. Do you have this dress in a smaller size?
A: Yes, how about this one then?
B: This is the right size. How much is it?
A: Sixty US dollars.
B: Give me a better price, please.
A: Forty dollars then. This is the best price I can offer you.

A：有什么可以为您效劳的吗，先生？
B：有的，我能看看展示柜内的那件衣服吗？我正在为我太太找件礼物。
A：当然，您知道您太太穿几号的衣服吗？
B：我不知道她的尺码，不过我认为这件衣服太大了，您有没有同款小一号的？
A：有。这件怎么样？
B：这件挺合适。多少钱？
A：60美金。
B：请给个便宜点的价钱。
A：40美金。这是我能给您的最低价了。
