    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.

    Topic 2：My View on College Students’ Use of Mobile Phones　　Questions for reference:　　1) What is the phenomenon of college students’ using mobile phones?　　2) What might be the advantages and disadvantages of their using mobile phones?　　3) What could be done to this problem?

    正确答案： 【参考答案】
    My name is... My registration number is... My topic is: My View on College Students’ Use of Mobile Phones.
    China is becoming a country with the biggest population of mobile phone subscribers and an increasing number of college students are joining the existing users. Statistics show that eight out of ten college students have got one. However, is it necessary for a college student to own a mobile phone?
    In my opinion, there is nothing wrong for a college student to have a cell phone, with is, students will be better connected with friends and parents. What’s more, mobile phones play an important role in graduates’ job-hunting. Therefore, instead of banning the use of mobile phones, schools should take measures to guide an appropriate use of them on campus, For example, students are required to switch off their phones in classrooms and under no circumstances should they use a mobile phone during exams. In some public places, like libraries, a poster can be placed at the entrance to alert library users to switch their phones to vibration mode before they enter the library.
    I believe mobile phones can bring benefits to our students as long as we can make good use of them.
