阅读理解Lily was a cheerful (开朗的) girl. She always had a big smile on her face. One day, she noticed an old man named Grumble sitting beside a river. The old man looked sad. Lily wanted to make him smile, so she walked up to him with a friendly greeting. "Good morning, Mr. Grumble! Why the long face?" she asked.
Grumble said, "What's there to be happy about? Life is full of troubles." Lily laughed and replied, "Troubles are like big and scary thunderclouds (雷雨云), Mr. Grumble. But just like clouds, they pass, making way for the sun to shine again. You should try looking on the bright side!"
Lily made a bet (打赌) with Grumble, saying, "I bet I can make you smile by the end of the day." Grumble challenged her, "You're welcome to try, but it won't be easy."
For the rest of the day, Lily did all kinds of funny and silly things to make Grumble laugh. She told jokes, sang like nobody was watching, and even made faces. However, Grumble was still unhappy. As the sun began to set, Lily decided to give it one last try. She took a deep breath and broke into a joyful dance.
Surprisingly, Grumble couldn't help laughing. He let out a chuckle (咯咯笑声), and then another. Before he knew it, he was laughing heartily, his sadness giving way to happiness. Lily had won the contest (比赛), but more importantly, she showed Grumble that becoming cheerful was not difficult.
Happiness is a choice, and we can find it when we choose to see the brighter side of life.
