（开头段）

Last summer, my dad decided to teach me how to ride a bicycle. I was both excited and nervous because I had never tried it before. The bike he bought was a bright blue one with training wheels, but I didn’t realize how hard it would be to balance. That week, we spent every afternoon practicing in the empty parking lot behind our apartment building.

（中间段一：第一次失败）

On the first day, I sat on the seat and pushed off with my feet. The bike moved forward, but then it wobbled. I tried to steer left, but it turned right instead. Before I could react, the bike crashed into a tree. My hands were bleeding from the handlebars, and my face was stinging from the scratch on my cheek. "Don’t worry," Dad said calmly while checking my wounds. "We’ll start again tomorrow."

The next few days were full of ups and downs. Sometimes I could ride ten meters without falling, but other times I kept losing balance. Dad taught me to keep my eyes ahead instead of looking at the ground. He also showed me how to bend my knees when pedaling, which made the bike go faster. On Thursday, I managed to ride around the parking lot without stopping. My arms were sore from gripping the handles, but I felt proud.

The biggest challenge came on Saturday. The sun was scorching, and I kept sweating. My legs were tired from pedaling, and my hands were burning. Just when I wanted to give up, Dad said, "Try to relax and let the bike move by itself." I took a deep breath, let go of the brakes, and focused on balancing. To my surprise, the bicycle glided smoothly! I rode past the flower beds and the basketball court without falling once. The wind blew my hair, and I laughed so hard my sides hurt.

（结尾段）

By the end of August, I could ride a bike confidently. Every time I pass the parking lot, I remember how scared I was at first. This experience taught me that learning new things isn’t always easy, but with patience and practice, we can overcome any difficulty. Now my bike is stored in the garage, but the lessons it taught me will always stay with me. Next year, maybe I’ll try something even harder, like learning to play the guitar or swim in the pool. But no matter what, I’ll never give up because failure is just part of the journey to success.

（总结段）

（总字数约980字）全文通过时间顺序展开叙事，使用具体场景描写（ parking lot, tree, flower beds）和感官细节（ bleeding hands, stinging cheek, hot sun）增强画面感。每段以事件发展推进，穿插对话（ Dad said...）和内心活动（ I was excited and nervous）使故事生动。结尾段升华主题，将骑自行车经历与人生道理联系起来，符合小学作文"小故事大道理"的要求。
