写一段对话

两人已经问过好后,进入问答的情境：最简单的：Grace: what's this? 这是什么?Helen: It's a tangerinean.这是个橘子. (It's an orange. 这是个桔子.) -----------------------------Grace: what's this in t...能详细点吗？好像太少了。能否把你想要的具体情境说一下，这样不至于我的表达离题。也就是你把想要表达句子说一下，我主要进行翻译。下午Grace与Helen见面，互相问好。他们准备彩笔给一些物品涂色，但Grace不知道其中的一件物品是橙子，所以问Helen。（写一段对话）这段对话从什么地方开始呢？问候Grace: Hi, Helen. How are you?Helen:I am fine, thank you. And nice to meet you. Grace: What are you going to do?Helen: I am ready to do some painting. Would u like to join in?Grace: Great, I am glad to do that. Where are the color pens?Helen: They are in my bag.Grace: Let me see. Helen: Ok, there are so many pens…Grace: Yeah, but what's this?Helen: Oh, it's a tangerinean.Let'shave it.
