今天是2020年11月22日，大学英语六级口语考试今天举行。大学英语六级口语考试分三个部分，部分是自我介绍和问答，第二部分是陈述和讨论，第三部分是问答。本场口语考试讨论的主题为“various tests”，讨论的主要内容是“机考是否将代替纸质考试”以下展示一篇讨论，供考生参考。

Candidate A: Due to the epidemic this year, many paper tests have been converted to computer-based ones. Do you have any ideas about it?

Candidate B: Yeah. I have just taken a computer-based test last month. I think it is very convenient and efficient. I just need to open my computer and do the test.

Candidate A: Well, of course computer-based test can reduce many processes, but does it guarantee fairness and equality of the test?

Candidate B: As far as I am concerned, computer-based test can’t fully guarantee the fairness of the examination. For example, the rural network is worse than the urban network, which is very unfair to the rural candidates.

Candidate A: Yeah, I agree with your idea. In addition, it’s not very safe. If the computer crashes or the Internet is disconnected, the exam will not go smoothly.

Candidate B: What’s more, popularizing the computer-based test is not simple. It requires sufficient funding and technical support.

Candidate A: So, In the future of artificial intelligence, computer-based tests may replace paper-based tests, but they will never replace the reliability paper test brought.

Candidate B: Well, I hoped that the computer-based test can not only provide convenience for exams, but also improve its security and stability.
