W: Hi, Jim, I have something urgent to talk over with you. Could you spare a few minutes right now?
M: Sure, come in and take a seat, please. What’s on your mind?
W: I was just talking to the library supervisor. He said the main frame was repaired yesterday. That helps a lot, but there are some other problems with our students.
M: Again? What’s the problem this time?
W: He said the students were supposed to reserve the terminal computers for only one hour a day because so many students need to use them every day.
M: We’ve already made it as a regulation to reserve the terminals within the hour given, haven’t we?
W: Yes, we have. But quite a number of our students are required to accomplish such assignments as designs and researches towards the end of the semester
M: I can see that. But does it bring about any problems?
W: Well, now it frequently occurs that some of our students aren’t willing to give up terminals when their hour is over.
M: I suppose they feel that since they are almost done few more minutes won’t matter.
W: Yes, most likely. But this renders(使变得) it inconvenient for people who are waiting for their turn to use the machine.
M: You’re right. Let’s draft the memo right now. We can pass it out in our classes tomorrow to clear up the problem. To make it known to all will be crucial to the solution.
W: I agree. And now I consider it a necessity to tighten the control over the time limits.
M: OK. Let’s get started right away.
