I’m Leo. I’m 12 years old. I’m tall and strong. Before, I was short. I couldn’t     1     my bike well. Now, I often     2     cycling with my brother. He is 2 years     3     than me. He usually     4     to school by subway. He likes science. He wants to be a     5     one day. Last weekend, we     6     to the ocean world. We     7     lots of sea animals there. We enjoyed a dolphin (海豚) show. They     8     bigger than us. They can do maths exercises. How clever!
