Casimir and Malia rode their bikes along the river trail. The sun was warm, and the path was empty that morning.
卡西米尔和马莉娅沿着河边小路骑自行车。阳光很暖，那天早上小路上一个人也没有。
Halfway through the ride, Casimir's bike made a strange clicking sound. Then the pedals stopped turning. The chain hung loose by the back wheel.
骑到一半，卡西米尔的车发出一种奇怪的咔嗒声。接着踏板就不转了。链条松松地垂在后轮旁边。
"My chain came off," Casimir said. He got off his bike and looked down at it.
“我的链条掉了，”卡西米尔说。他下了车，低头看着车子。
Malia stopped beside him. "Do you have a tool kit?" she asked.
马莉娅在他旁边停下。“你有工具包吗？”她问。
"It's in my bag," Casimir said. He pulled out a small kit with a chain tool inside.
“在我包里，”卡西米尔说。他拿出一个小工具包，里面有一把链条工具。
Malia held the bike steady. Casimir worked on the chain. He looped it back over the small gears and pulled it tight.
马莉娅扶稳车子。卡西米尔动手修链条。他把链条重新套回小齿轮上，再拉紧。
"There," he said. "That will fix it."
“好了，”他说，“这样就修好了。”
He turned the pedal slowly. The chain moved smoothly around the gears.
他慢慢转动踏板。链条顺滑地绕着齿轮转动。
"Try it now," Malia said.
“现在试试看，”马莉娅说。
Casimir got back on the bike and pushed off. The chain held, and the wheels turned without a sound.
卡西米尔重新骑上车，蹬了出去。链条没有再掉，车轮转起来一点声音也没有。
"It works," he said. "Thanks for waiting."
“好使了，”他说，“谢谢你等我。”
"That's what friends do," Malia said. She got back on her own bike.
“朋友就该这样，”马莉娅说。她也骑上了自己的车。
They rode the rest of the trail together, side by side.
剩下的路，他们并排一起骑完了。
