You are asked to discuss about it.　　Discuss the situation and decide:　　● Is it practical or not　　● name the advantages and disadvantages　　● If needed, cite the accurate example to fight for／against it.

    正确答案： A: Well, the management’s proposal on flextime is today’s topic. What are your opinions on this?    .
    B: I think our staff members would be happy with this practical idea. They have complained that the present working time is too restricted. They say the working time should be flexible.
    A: In what ways?
    B: The company should allow the staff to build up a credit of hours to entitle them to take a few hours or a day off.
    A: But don’t you think there would be chaos?
    B: What do you mean by “chaos”?
    A: There would be no one in any department knowing who was in at what time. And people who phone the company or visit our company would get terribly confused.
    B: Well, I’m sorry to interrupt. In my opinion, we should make cover arrangements. When people are sick or when people take holiday the same kind of arrangements is made.
    A: Er. Mr. Brown, what are your views?
    B: Frankly, I think it’s difficult for our section to have flexible time. There are three of us in our section and we work as a team. Therefore, if we had anyone off then we wouldn’t be able to manage.
