听力原文: The expression, " lame duck", can be heard in almost any American town or city, especially where people discuss politics. Most often, they use it to describe a politician who has come to the end of his power.<br>There are a number of ideas as to where "lame duck" came from, though the picture of a lame duck is clear enough; a duck that has had its wings cut, or its feet injured, and can no longer walk like a healthy one.<br>The term seems to have come into the American language after the Civil War of 1861-1865. One explanation is that it came from the language of hunters who felt that it was foolish to waste powder or time on a dead duck. And a lame duck is close to being a dead duck.<br>Another explanation, however, is that the expression came from England. There it was used to describe a man who lost all his money and could not pay his debts. He could do nothing but walk like a lame duck. And people showed little mercy for the poor fellow.<br>But in the United States people took the phrase to describe congressman who failed to get re-elected but still had a little time left in office.<br>Later, the expression was used in a broader sense, generally describing any man whose days of power were coming to an end. It has often been used to describe the position of an American president in the last two years or so of his second term. It is a difficult time for him, when Congress is ready to oppose him at every turn.<br>Where can the expression "lame duck" be heard?

A. Only among hunters.
B. Among primary school pupils.
C. Among beautiful ladies.
D. Among people who are discussing politics.

Welcome to Central College library services. My name's Kathy Jenkins. I'll give you a brief introduction to the library. We have a well-stocked bank of resources which are located in three main places: the library itself, with books and periodicals; the self-access language centre, with audio and video material; and the micro-computer lab. I'll start with the micro-computer lab, or micro-lab as we call it. It is fitted with 24 personal computers.<br>If you are a member of the library, you may borrow CALL discs in French, German, Italian, Spanish and Russian as well as English. By the way, CALL stands for computer aided language learning: C-A-double L, "CALL" , for short. You may also borrow a range of word processing and desktop publishing packages. All disks are, of course, strictly for use in the micro-lab only. If you wish to print anything you should use one of the five machines around the outside of the room. Four are connected to dot matrix printers, one is connected to the laser printer. If you want a better quality printout from the laser printer, come and see me or any of the library staff. Dot-matrix printouts are free but there is a charge for using the laser printer. There is always a queue to get to the terminals towards the end of term. Come in and get to know how to use the computers early in the term and use them regularly, rather than just before exams and essay deadlines, in order to avoid delay or disappointment. Training sessions are held on a regular basis, on the first and third Thursday of each month, and are free to full-time students of the college. See you there. Now, any questions?<br>What does the speaker suggest that the students should do during the term?

A. Consult with her frequently.
B. Use the computer regularly.
C. Occupy the computer early.
D. Wait for one's turn patiently.
