有一天，小明叫着小刚出去玩飞机模型，他们来到公园里，看到了蓝蓝的天空，绿绿的小草，心里觉得很舒服。
One day, Xiaoming called Xiaogang out to play with the airplane model. When they came to the park, they saw the blue sky and green grass. They felt very comfortable.
他们来到了草坪上，一起放飞各自的小飞机，小明的飞机慢慢的飞上了蓝天，小刚的飞机却落在了地上。小明就过来跟小刚一起修理飞机。
They came to the lawn and let their small planes fly together. Xiaoming's plane slowly flew up into the blue sky, while Xiaogang's plane landed on the ground. Xiao Ming will come to repair the plane with Xiao Gang.
小明说：“我们要仔细找出飞机飞不起来的原因。”“当然了。”小刚回答说。
"We should carefully find out the reason why the plane can't fly," Xiao Ming said "Of course." Xiaogang replied.
经过两个人的努力，小刚的飞机终于飞上了天空，他们高兴的坐在草坪上，好像在说：“我们成功了！”
After two people's efforts, Xiaogang's plane finally flew into the sky, and they happily sat on the lawn, as if to say: "we succeeded!"
