B By now there were several people standing around me, my mom, and the little broken bush(灌木丛). “Son, would you like me to call an ambulance?” some men said. “No,” my mom yelled. “I’m fine. Please go away!” “She’s learning to ride,” I tried to explain to all those who were not going to go away. “Oh, all right!” My mom sat up and brushed the grass and leaves off her sweater. Finally she stood up. Everyone began to clap(鼓掌), and my mom’s face turned bright pink. “Thank you very much, but as you can see, I’m just fine.” Mom took a few steps around to show them that she wasn’t hiding a broken leg. Everyone clapped again and then went on their way. “Enough for today?” I asked hopefully. “No,” she said in a way that surprised me. “I almost had it, and then I let myself get scared. I know I can do it this time!” Now this sounded more like my mom, for I’d never known my mom to be afraid of anything before. I helped her pull the bike out of the bush and push it up the hill. She didn’t look quite so pale this time. She got on the bike again and went down the hill. I ran down the hill after her. She had ridden quite a way ahead of me when she looked back over her shoulder, smiling. Then she gave me a thumbs-up(翘拇指) sign. “No, no!” I yelled. “Use both hands!” But it was too late. Again. “Mom! Are you hurt?” I ran up to her in the grass. This time she was laughing. “Did you see me? I did it! I really did it!” Then she stopped and looked at me. “I mean,” she said, “we did it.” 60.
