"Hey, everyone, listen!" Mr. Lee said with a big smile, but he sounded serious as he started our1 class. "I' ve got a fun job for you. Every class, I' ll hide(隐藏)a 2 . Your job is to find it! Sounds cool, right?"
We were happy to turn geography into a game. Learning about places and maps is 3 , but this made it exciting.
For weeks, we listened very carefully to every word Mr. Lee said, trying to catch 4 ina lie(谎言). We took notes and studied them with our classmates, 5 clues(线索).
But Mr. Lee was smart. He made everything sound real, and if we didn't find the lie, he'd just laugh and say, "Keep 6 , everybody! You' ll get it. And I' ll tell you at the end of the term. "
This made us 7 geography even more. We talked about it after class, sharing ideas and thinking about what might be the lie. Everyone enjoyed it.
Then, the last Monday of the8 came. We were ready to hear Mr. Lee' s lie. After finishing the lesson, he said, "Remember the lie I hid? Well, here's the result: Everything that I taught you is 9 . In fact, there wasn't a lie! But the real lesson is to10 think deeply about what you learn. "
We were11 about the result as we never thought about it. We' d been tricked(戏弄) into learning, but it was the 12 trick ever! We thanked Mr. Lee for making geography lessons so13 and unforgettable.
14 I don't remember much of the geography now, I still remember the lesson Mr. Lee taught us: always ask questions and think deeply. It's a meaningful 15 that will stay with me.
