Kids are engaged -- they have laptops! -- and then the fifth, which interests me the most, is that the servers have to be turned off at certain times at night because the teachers are getting too much email from the kids asking them for help.
孩子们积极参与。他们都有笔记本电脑。 第五点我觉得最有趣， 那就是到了晚上某个时间，他们必须把服务器关上。 因为老师们收到的电子邮件太多了 许许多多的孩子请求帮助。
