运用隐喻手法，将抽象的人生压力具象化为“shell”，生动地表达了人生充满负担但需持续向前的哲理。
III. Discussion:
How do we move forward while carrying our "shells"? Watch the animation "The Snail and the Oriole" and listen to the song, then ask students to summarize their own answers based on the insights.
Story One: Hans, a fitter from Frankfurt, Germany, was obsessed with music from a young age. He practiced on a mock keyboard made of steel plates and eventually became a key composer for Hollywood film music. He won an Oscar for "The Lion King."
Story Two: Selma lived a hard life in the desert. Her father wrote to her: "Two men, looking out from the iron bars of their cell, one saw dirt, while the other saw stars." This changed her life.
Story Three: After falling into a dry well, a donkey shook off the sand and dirt from its back, stepping out of the predicament one by one.
Conclusion: Life is a process of moving forward with a "shell" on our backs. No matter how heavy the shell is, we hope students can be like the snail, turning pressure into power to climb the pyramid in their hearts.
VIII. Ending
Play Jay Chou's "Snail" and lead the whole class in a chorus.
三、讨论：
我们要如何背着“壳”前行呢？看动画《蜗牛与黄鹂鸟》听歌曲，并要求同学们根据启示去归纳出自己的答案。
故事一：德国法兰克福的钳工汉斯，从小就迷上了音乐。他用钢板制作的模拟黑白键盘练琴，最终成为好莱坞电影音乐的主创人员。他曾凭《狮子王》荣获奥斯卡奖。
故事二：赛尔玛在沙漠中艰苦生活，父亲写信说：“两个人，从牢中的铁窗望去，一个看到泥土，一个却看到了星星。”这改变了她的生活。
故事三：驴子掉进枯井后，通过抖落背上的泥沙，一步一步走出了困境。
总结：人生是一个背着“壳”前行的过程。不管壳有多重，希望同学们能够像蜗牛那样，化压力为动力，爬上自己心中的金字塔。
八、结束
播放周杰伦的《蜗牛》，带引全班同学合唱。
"Make your own decisions and bear the consequences."

"No matter how bitter or tiring it is, it is the path you chose for yourself."
"A gentle woman becomes sharp because a man fails to step up."
