2d Role-play the conversation.
Frank: Hi, Bob. How’s your day?
Bob:
It’s OK. I like Monday because I have P.E. and history. They’re my
favorite subjects.
Frank: Who’s your P.E. teacher?
Bob: Mr. Hu. He always plays games with us.
Frank: That’s great! But why do you like history? It’s boring.
Bob: Oh, I think history is interesting. What’s your favorite day?
Frank: Friday.
Bob: Why?
Frank: Because the next day is Saturday!
Bob: Haha! That’s for sure. I like Friday, too.

题目是个错的是2d

这个是编程语言上的内容，指对一个整数或小数，保留两位小数，-号表示保留小数，2指保留位数，d指是数字（不是字母或别的）

2d是平面 I(二维) 3d是立体 （三维）

刚好有，点我的头像

写出来文字呀

这个用法很普遍，很多场合都有涉及。
就是2d平面的意思。我们还会用3d，表示看到的是立体画面。
