  • 第11题：

    问答题
    Discuss, and decide together:　　● What kinds of reasons might there be for staff leaving their jobs?　　● What steps could be taken to reduce staff turnover?

    正确答案：
    【参考范例】
    Candidate A=A Candidate B=B
    A: Let’s get started. I think a lot of reasons account for staff leaving their jobs. Among these reasons, the most common one may be that some staff members feel that he/she is earning very little in his/her job. What do you see it?
    B: Well, I also think there are several reasons, really. I mean, with employees expanding their horizon their outlook becomes more global. To employees, certain questions may be asked like: What do you enjoy about working here? Over the past year, have you considered about leaving? If so, why is that? What can be done to improve our company and create an even better place to work? Form employees, we are most likely to get answers like they want better training, better working conditions and better communications with their supervisors. And, above all, they want their bosses to “make me feel like I make a difference”.
    A: So how can we weigh up all these factors and take appropriate steps to reduce staff turnover?
    B: Well, it’s vital that the management knows exactly what they want from staff and that they have a full understanding of their key steps, one of which is linking pay and bonuses with performance. What do you think about it?
    A: Yes, it’s difficult to change how things are done. Just like people, bureaucracies fall into bad habits, and the process of adapting to change can be painful. All the departments of the company should do their job well to reform the rules and working environment. So far as I am concerned, most employees are reliable and loyal and they are willing to take hard work.
    B: That’s true. Surveys have been conducted recently. They show that when 15,000 employees in retail shops across the country were asked to list the 18 reasons for working where they did in order, they ranked “good pay” third. And “appreciation of work done” is in first place, with “respect for me as a person” second.
    A: Therefore, the management need to put high value on staff moral. High labor turnover that results from the indiscriminate hiring of “cheap” workers can cost a lot. Many companies have declared a “war for people” so as to recruit and keep better staff.
    B: If correct steps are taken to boost staff moral, labor turnover is bound to decline by more than haft. There is enough evidence that the management should spend more money on retaining employees if they hope to spend less on finding and training new ones.
    A: I agree with you. I think, to reduce its labor turnover, we need to get across a simple message throughout our operating divisions, that is loyal, well-motivated employees make customers happy, which in turn, creates bigger profits and happier shareholders. It could also help to improve training of middle manager.. So could a change in bonus arrangements.
    B: Meanwhile, the senior managers may become fussier about the people they recruited. They prefer to screen out job applicants who are mainly motivated by money, in other words applicants, who are pejoratively described as “pay first people” by some companies. Such people make up a surprisingly small, yet evidently disruptive, part of the service-industry workforce. Many companies found in its employee-attitude surveys that only about 20% of their workers regarded pay as their principal reason for working there.
    A: Probably, you’re right. But people do annoying things out of their own will in exchange for money or entertainment, so they may go for the bait. And many middle managers in service industries are more comfortable managing demands for more money than those for increased recognition and better communications. They will need to change their ways. Well, let’s conclude what we have said and make a decision, shall we?
    B: Yes, first we will go over the questions, and then make decisions together.

    问答题
    Practice 5　　‘Mini presentation’—about 6 minutes　　In this part of the test you are asked to give a short talk on a business topic. You have to choose one of the topics from the three below and then talk for about one minute. You have one minute to prepare your ideas.　　A  WHAT IS IMPORTANT WHEN…?　　Selecting a secretary for the general manager　　● Qualifications　　● Related work experience　　B  WHAT IS IMPORTANT WHEN…?　　Cancelling a business meeting　　● Making an apology　　● Reasons for cancellation　　C  WHAT IS IMPORTANT WHEN…?　　Motivating staff　　● Bonuses offered　　● Pleasant working environment

    正确答案： 【参考范例】
    If you choose topic A:
    When selecting a secretary for the general manager, we must first of all consider if he or she has the qualifications needed. A candidate with adequate knowledge of office skills and public relations will be an ideal one.
    Related work experience is also of great importance. A skilled secretary can accomplish the office work quite satisfactorily. People with little experience sometimes will inevitably feel confused when dealing with the complicated relationships around the general manager.
    In addition, the secretary should have a good personality because a good character will help a lot in smoothing the communication with the general manager and other staff members.
    If you choose topic B:
    When cancelling a business meeting, firstly an apology for the cancellation is necessary due to its effect on the participants’ schedules and the inconvenience it has caused to others. A business meeting is not supposed not be easily cancelled if there are other alternatives.
    After the apology, you should give the participants reasons for cancelling the meeting and make it convincing and sincere. Normally, participants will show their understanding and tolerance if the thuth is told and the attitude is acceptable. In case some participants have already arrived at the meeting venue or on the way to it, there should be an another plan to compensate for the time and financial loss of the participants.
    Finally, new dates for the meeting should be set so that the participants can be better prepared.
    If you choose topic C:
    I believe that we all know the significance of motivating staff to increase their productivity and their contribution to the company. The inspired staff is more likely to enjoy the job and work more actively. There are various ways to motivate staff, of which giving bonuses is quite effective. Occasional stimuli of money will drive the staff forward.
    Plus, a pleasant work environment is also very important in motivating staff since people like staying in a clean and tidy office where they can work more efficiently. A well-equipped office will help staff do more meaningful and creative work.
    In addition, team spirit and trusty colleagues can also contribute in motivating staff.,which will always make everyone enjoy the work.
