The first advantage is that students can choose the thing they want to practise or to learn. Secondly they can get immediate feedback, individual feedback, from the machine on whether they are making progress or not. And they can give up when they are tired or carry on if they're not tired. They don't have to depend on the rest of the class or the rest of the group. It's very advantageous. But I think most forms of teaching and most forms of learning are not possible by computer. I think the computer provides a lot of information when you want it. But it doesn't provide the essential feature in language learning, I think, and that is the practice of speaking to another human being or human beings. It's just an extra device, that's all. It's not intended to replace teachers and I don't think it will replace teachers.
第一个好处是学生可以选择他们想练习或者是想学习的习题来做。第二个好处是他们能得到直接的反馈，个人的反馈，机器会分析他们是否进步。当他们疲惫时，他们能选择放弃做题，或者不疲惫的时候，可以选择继续做题。他们不需要根据剩下的课程或者是组来决定是否继续做题。 这是非常有益的，但我认为教学和学习的方式不可能仅仅依靠电脑。我认为当你需要的时候，电脑提供了很多信息，但它不可能提供语言学习的本质特征，我认为那是人类语言的说话训练。这仅仅只是额外的辅助设备而已。电脑不会取代老师，而我也这样认为。 ——By lsy34
