一、完形填空。
Ever since Lisa was little, she has loved playing in the city park. So, when she saw a poster（海报）at school asking for $\underline{1}$ to help clean it up, she knew she had to join. She had no doubt about $\underline{2}$, hoping to give back to the place that had given her so many $\underline{3}$ childhood memories.
The event was on a sunny Saturday morning. When Lisa $\underline{4}$, she was given a pair of gloves and a large trash（垃圾）bag. Their task was simple: to $\underline{5}$ the park of litter and make it beautiful again. At first, everyone worked on their own, $\underline{6}$ picking up trash. But the progress was slow. Then, they had a great idea—$\underline{7}$. They decided to work in a line, moving together across the big field. One person held the bag open, while others $\underline{8}$ bottles, bags, and paper. They laughed, shared stories, and encouraged each other. Working together turned a(n) $\underline{9}$ job into a fun game.
By the end of the day, they had $\underline{10}$ a great many bags with trash. The park looked completely transformed（焕然一新）—green and clean. The event was very $\underline{11}$, and the park manager（经理）thanked them with a smile.
That day, Lisa understood the true $\underline{12}$ of community service. It isn't just about the work you do; it's about the people you help and the friends you $\underline{13}$ while doing it. Although she was tired, she knew it was $\underline{14}$ it. She left the park feeling proud and happy. $\underline{15}$ that experience, Lisa has looked at her favourite park differently—not just as a place to play, but as a place she helped protect.
