上次课我们学习了怎样与客人谈论行车时间，我们练习的魔术句子是“我们什么时候可以到呢？”

Last time we learned how to talk with a passenger on traveling time, and we practiced the magic sentence "When can we arrive".

到目前为止，我们谈论的“隐性时刻”是那些既可以用来阅读（看学习卡片）或是练习听力（听磁带）的时间。

So far your hidden moments have been those that could be utilised either for reading (flash cards) or listening (cassettes).
