先看看这个场景说了什么
对话 1
Hi, do you need a hand? I saw the red light come on above your checkout.
你好，需要帮忙吗？我看到你这台结账机上方的红灯亮了。
中文提示
Yes, please. It keeps saying there's an unexpected item in the bagging area, and I don't know why.
需要，谢谢。机器一直提示装袋区有不明物品，我不知道是怎么回事。
对话 2
I can see the problem. Your basket of unscanned groceries is on the bagging area, and your empty trolley is on the other side. They need to swap places.
我知道问题在哪了。你装着未扫描商品的购物篮放在了装袋区，空购物车却在另一边。它们得换个位置。
中文提示
Oh, I've got them the wrong way round. I'll move the basket over and leave the scanned items in the bagging area, right?
原来我放反了。我把篮子挪过来，扫过的东西留在装袋区就行，对吧？
对话 3
Exactly. I've cleared the warning, so you can carry on scanning now.
对。我已经清除了警告，你现在可以继续扫描了。
中文提示
Great, it's working now. Hang on, the price of this cereal doesn't look right either.
好了，现在正常了。等一下，这包麦片的价格好像也不对。
