Kareem still short as he counted his money again. He was six dollars short of fifty dollars to buy the latest Speedster X bike. In order to save pocket money to replace his old bike, he had been packing sandwiches for school the last three months.
"How can I get that fifty dollars?" he thought to himself. His mind was wandering when Mother's voice disturbed his thoughts. "Kareem, I just ran into Aunty Kim, our neighbour who just moved in next door. Her son, Shawn, will cycle to school next week. Could you show him the shortcut to school later? It's Saturday anyway!" Hearing this, Kareem had no option but to obey her. He knew Mother had probably volunteered his service to Aunty Kim. "Oh, here's mail from your Grandma. Open it!" added Mother. Kareem's grandmother lived abroad, but she would send him photos and cards. He opened the envelope and pulled out a greeting card. Incredibly, a fifty-dollar note slipped out! Waving the note in the air, he shouted happily, "Enough money for my bike!"
At 2 p.m. Kareem met Shawn as arranged by their mothers. The sooner he finished the task, the sooner he could go to the bike shop. While the boys were cycling, a squirrel appeared behind a parked car and dashed across the road so suddenly that the boys knocked into each other and fell down heavily. Kareem said regretfully, "I felt so worried about the squirrel population here." As Kareem was lifting up his broken bike, Shawn cried anxiously, "Oh, my poor bike! It's completely broken."
Watching Shawn carrying the broken bike home in silence, Kareem hurried to the bike shop for his dream bike. The sign "Half Price for Old Models" in the shop attracted his eyes.

答案：Paragraph 1:
"A Speedster X bike or two old models?" Kareem hesitated. He had long dreamed of owning the latest Speedster X bike, but seeing Shawn's sad face when his bike broke, Kareem's heart softened. The "Half Price for Old Models" sign gave him an idea. He calculated quickly: with the fifty dollars, he could buy two old models at half price. One for himself and one for Shawn! That way, both of them could have bikes to ride to school. Without further hesitation, he decided to buy two old models.
Paragraph 2:
"Hi!" Kareem appeared at Shawn's door cheerfully and asked, "Want to ride together?" Shawn looked surprised and then saw the old bike behind Kareem. "This is for you," Kareem said with a smile. "I know your bike broke, and I bought two old models. Now we can ride to school together." Shawn's eyes lit up with joy. "Thank you so much, Kareem!" he exclaimed. From then on, the two boys rode their bikes to school every day, becoming good friends. Kareem felt happier than ever, realizing that helping others brought more joy than owning a new bike.
解析：Paragraph 1 开头Kareem犹豫买新自行车还是两辆旧自行车，结合前文Shawn自行车坏了的情节，合理推断他会选择买两辆旧自行车帮助Shawn。Paragraph 2 Kareem带着自行车去Shawn家，邀请他一起骑车，Shawn很高兴，两人成为好朋友，点明帮助他人带来快乐的主题，符合续写要求，情节连贯，词数适当。
