买的衣服尺寸不合适，只好去商场换货啦！那么“换货”用英语应该怎么说呢？看完下面的对话你就知道了。
A-buyer B-seller
A: Excuse me. I'd like to exchange this blouse.
对不起，我要换这件衬衫。
B: What's the reason?
什么原因?
A: It's the wrong size.
尺寸不对。
B: Do you have the receipt?
你有收据吗?
A: Yes, I have.
是的，我有。
B: Go ahead and pick up your size and bring it here, please.
请去挑尺寸合适的来。
A: Ok, where is the fitting room?
好的，试衣间在哪?
B: It's behind you.
就在你后面。
清楚没？换货时带着你的购物凭证receipt, 讲明reason, 要求exchange就可以啦！
