[originaltext]W: Hi, Tom. How’s it going these days?M: Fine. Where are you hea

W: Hi, Tom. How’s it going these days?
M: Fine. Where are you heading?
W: I’m on my way home from work.
M: I didn’t know you had a job.
W: Yeah, [19] I work part-time at the library because I really have a lot of spare time this semester.
M: What did you do there?
W: Well, [20] I work in the information, giving suggestions to those looking for reference books. Sometimes when it really gets busy, I also help the librarians categorize the books. Have you got a job, Tom?
M: [21] I really want to, but I do have a hard time with the reading list and the courses I signed up for this term. Well, it seems that you work there every day.
W: Yeah, I think that’s the trouble. There are times when I get pretty tired of answering different questions. But a job is a job.
M: I guess every job has its drawbacks.  But today I do need some of your suggestions. I wonder if this book fits me.
W: Well, let me see. [22] I think the book has little to do with the topic of your paper. I mean you plan to write the present conditions of the Chinese minorities, but this book is about all the minorities in the world. I think it’s too general.
M: Well, I’m afraid so.  I think I have to look for another one.  Thank you anyway.
