What's that book you just picked up, Mary?
The one Prof. Lee uses in his course.
Oh, I see. You'd better have it if you want to pass that course.
哦，我明白了 。你要想通过这门课程，你最好要买它 。
But it costs $30. I simply can't afford it.
但是它卖30美元 。我真的买不起啊 。
Did you check the used book section here? Maybe they have it.
No, they don't. I asked.
没有，那里没有 。我问过了 。
Why don't you get it from the library?
I've been trying for months, and it's always out. There are over 50 students in the course, and every single one wants the book.
这几个月来我一直想借，可它总是被借出去了 。有50多个学生上这课，而且每个人都想要这本书 。
Listen, you know my roommate Henry, don't you? He took the same course last year, and I remember he owns a copy.
I can borrow it from him for you.
Oh, that'll be great! Thank you, Jim!
