用英语学英语口语：a red eye flight 红眼航班
这是一个用英语说英语的口语训练，不是用中文“认字”的扩大词汇量学习。
用英语学英语，我们只会得到更多和积累的英语，也会复习已经学过但没用过的英语，也会训练了口语。
用中文学英语，你只是得到了一个中文词和用英语“认识”了一个英语词汇。
“用中文认字”和“用英语学英语”是两个多数人没有注意到的完全不同类型的英语学习。
通过本次训练，你应该能用英语回答、记住并能与人用英语简单交谈以下问题，而不仅仅是用中文“红眼航班”记住一个英文单词a red eye flight：
1) What is a red eye flight?
2) Why is it called a red eye flight?
