第26题: [多项选择]FLEXTIME
Your company is planning to adopt flextime. You have been asked to submit ideas on it.
Discuss and decide together:
the pros and cons of adopting flextime
which employees are eligible for this benefit
参考答案:Interviewer: Well, Fan Zhe and Wang Hao, the last part of this speaking test is a discussion task. Your discussion topic is on this task card. You have about C0 seconds to read it carefully. After you have read the task, you will have a discussion on the given topic. Your discussion time is around three minutes. OK Now read your task card.
(C0 seconds later)
Well, can you start your discussion now I’m going to listen to you and then ask you to stop at the end of three minutes.
Wang Hao: Well, I think, nowadays, as companies become more global, with work taking place at all hours, flexible schedules, from both an employer and employee standpoint, are becoming more necessary.
Fan Zhe: I agree. If a company allows its employees to work reduced or alternative hours according to their different situations, it could help reduce their anxiety coming from the fear of imbalance between work and family, which could, to some extent, improve their performance at work. It’s actually a plus for the company.
Wang Hao: That’s true. But don’t you think there is a risk that employees won’t be connected to the office by working at varying hours.
Fan Zhe: No, I don’t think so, because technologies like laptops, e-mail, cell phones, and pagers could easily solve this problem. So your concern is quite unnecessary. But there is one problem with working flex time, especially with working reduced hours. That is, usually a cut in benefits would accompany working reduced hours. That’s a loss on the employee’s part.
Wang Hao: But I think if an employee wants to work reduced hours, he should be prepared for it. I meant he should be well aware of that problem when he makes that decision.
Fan Zhe: Well, I think we should come to the second point. Which employees are eligible for this benefit What do you think
Wang Hao: People who has a long commute from home to work should be eligible for working flextime. And ...
Fan Zhe: Sure. And I think working mothers, especially those with very young children also should be eligible for it, so that they could handle a child and a job at the same time without too much pressure.
Interviewer: Do you think there’s the risk of career penalties and of being "taken off the path" for employees who choose to work flextime
Wang Hao: Yes, it’s possible. Because, because
Fan Zhe: Because colleagues might consider flextime arrangements as special treatment, or they might think that an employee with flextime isn’t a devoted worker.
Interviewer: Thank you, Fan Zhe and Wang Hao. That is the end of the speaking test.

第37题: [名词解释]摊钢
参考答案:
在轧制过程中，在头几个道次钢板沿长度方向往往会发生弯曲，如果钢板比较短，加上相邻辊道间距较大，钢板就会卡在某个位置停滞不前。即使辊道不停转动，但由于钢板与辊道之间的摩擦力不够，钢板无法前进或后退，这种情况就叫摊钢。
