Amy: Today's homework is really hard, isn't it?
Ben: Yes, it is. We have so many questions to answer.
Amy: Mr. Chen didn't explain problem five clearly, did he?
Ben: No, he didn't. I had to ask my sister for help.
Amy: Your sister is in high school, isn't she?
Ben: That's right. She's really good at math.
Amy: The science test is on Friday, isn't it?
Ben: Yes! I almost forgot. We should study together.
Amy: We can meet at the library after school, can't we?
Ben: Sure. The library closes at six, doesn't it?
Amy: I think so. We should get there early.
Ben: You didn't finish today's English reading, did you?
Amy: Not yet. The story is too long.
Ben: It's interesting though, isn't it?
Amy: I guess so. The ending surprised me.
Ben: We won't have gym class tomorrow, will we?
Amy: No, the gym is being fixed. We'll have art class instead.
Ben: That's fine with me. You're good at drawing, aren't you?
Amy: A little. But I prefer music class.
Ben: The school concert is next month, isn't it?
Amy: Yes! We're going to perform together, aren't we?
Ben: Of course! Let's not forget to practice.
