【素养拓展作业】（示例）
Traditional arts like paper-cutting are in danger. If young people don’t learn them, they may disappear. I want to learn paper-cutting because it is a beautiful part of my culture. I will join a paper-cutting club at school. If I practise every day, I will become better. I also want to teach my friends because sharing skills makes them last longer. If more people join in, this art will stay alive. Let's take action now. Because every small effort matters. I believe the magic of tradition will last forever. I am proud to be part of it. That’s why I love traditional art. It connects me to my roots. I hope you will join too. Together, we can make a difference. That's my promise. I will never give up. Because this is my duty. This is my love. This is my art. I will keep it alive. Forever. That’s the power of tradition. And that’s the power of us. So let’s begin today. One step at a time. We can do it. I believe in us. Yes, we can. Let’s go!
