| Tracy sat at the kitchen table daydreaming. She was thinking about the used bike she planned to buy. She was making a list of things she wanted to do to fix up the bike. On her list, Tracy had written new seat, paint, and bell. Then she thought, "I want to make sure drivers see me on my bike. I'll add reflectors (反光镜) to my list." Tracy's dad walked into the kitchen. "What are you doing?" he asked. "Oh, I'm just thinking about the bike I want to buy", Tracy said. "I had hoped to earn enough on my paper route the first week to buy it, but I only made fifteen dollars. I hope the bike is still there after I get paid next week." "Well, if you would like to earn the money tomorrow, you can help me," Tracy's dad said. "Doing what?" Tracy asked eagerly. "I'm washing windows in the morning," her dad said. "I could use five dollars' worth of help." Even though it was a Saturday, Tracy got up quite early. She washed the inside of all of the windows. By twelve o'clock, she finished and had the money in her hand. Just as she was ready to leave, her mom called to her, "Tracy, did you make your bed?" Tracy rushed to her bedroom and made her bed. Finally, she headed for the door. She raced down the street to where the bike was for sale. Luckily, It was still there. The owner noticed Tracy looking at the bike. "Would you like to buy it?" asked the owner. "I sure would! I have twenty dollars," Tracy answered, pulling the money out of her pocket. Within minutes Tracy rode away wearing a huge smile. She circled the block several times. She wanted her friends to see her on her new bike. |
