在英语中，两个人购物的对话可能是这样的：
Person 1: "What do you want to buy?"
Person 2: "I'm not sure. What do you think we should get?"
Person 1: "Well, we need to get some groceries for the week. How about some fruit and vegetables?"
Person 2: "That sounds good. Let's also get some meat for dinner tonight."
Person 1: "Okay, we can get some chicken breasts. And do you want to get anything else?"
Person 2: "I think we have everything we need. Let's go to the checkout."
这是一个典型的两个人购物的对话，其中包括了问题和建议，并最终决定去结账。
另外，还有一些其他的常见用语可以用来表达购物的意思，例如：
"Do you want to go shopping?" (你想去购物吗？)
"I need to buy some new clothes." (我需要买一些新衣服。)
"I'm just looking around." (我只是在看看。)
"I'll take one of these." (我要买这个。)
"How much does this cost?" (这个多少钱？)
这些用语都是常用的表达购物的方式，在英语中很常见。
