2--What is it?

1--I've been having trouble with derivatives.

2--That's not good. There's a test on derivatives next week.

1--I know. Can I make an appointment with you for some help?

2--I'm a busy man.

1--You didn't even check your schedule yet!

2--I know I'm busy, because many people already made appointments.

1--So I'm hopeless?

2--Of course not! There's the tutoring center.

1--But the tutors are not professors. They're just students.

2--They might surprise you.

2--那不太好。下周有一个对衍生工具的测试。

1--我知道。我能和你预约个时间来获得你的帮助吗？

2--我是个很忙的人。

1--你甚至没有检查你的时间表!

2--我知道我很忙，因为很多人已经有了预约。

1--那么我是没希望了吗？

2--当然不是！有辅导中心。

1--但是助教不是教授。他们只是学生。

2--他们会令你吃惊的。
