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-sellerA: 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！
