Problem: 男的注册一门关于生物的课程,晚了，结果学校图书馆没借到书，书店也没得买了，卖没了。 Solutions: 1.去书店买。说是可以为他order新书但是要一个星期以后，来不及；2. buy old books from the students of last year. The man thought the condition of the used book is not good. He doesn’t like. 书上有被做过的标记，他不喜欢。
The man talks about his problem about his biology textbook. He needs the book for bio class, but it is not available neither in the library nor in the bookstore. There are two options. The first one is that he can order the book from the book store. The other option is that he can buy an old book from the students of last year. From my perspective, I think the first solution is better. The used book from other students might have some problems like missing pages or food stains etc. Some parts or contents missing from the book might be too important to the class, so the man won’t feel comfortable with the risks of buying a used book. Although he wouldn’t get the textbook until a week later, he can share with his classmates while waiting for his own.
