在昏暗拥挤的教室里，我注意到有位学生打呵欠并伸展四肢，抱怨这节课太简单和无聊了。

In the dim cramped classroom, I noticed a student who yawned and stretched his arms and legs, and complained how simple and boring the class was.

我是怎样地翻腾，打呵欠，打盹，又清醒过来！

他的冗长的故事听得我直打呵欠。

我感到很困，止不住地打呵欠。

“今天的讲座令人厌味。我担心我要打呵欠了。那就太糟糕啦！”(打呵欠)。

"I was so bored with today's lecture. I was worried I'd start catching flies. That would have looked terrible!" (Yawning).
