When a light plane flew off line (偏离航线), it hit (撞) the mountains and its pilot (飞行员) was killed. The only passengers (乘客), a young woman and her two baby daughters were unhurt (没受伤). It was the middle of winter. Snow was thick on the ground. The woman knew that the nearest village was kilometers away. When it grew dark, she turned a box into a bed and put the children inside, covering them with some clothes. During the night, it got very cold. The women kept as near as she could to the children and even tried to get into the box herself, but it was too small. Early next morning, she heard planes passing over her head and wanted to know how she could send a message (信息). Then she had an idea. She stamped out (踏出) the letters“SOS”in the snow. A pilot found the message and sent it by radio (通过电话) to the nearest town. It was not long before a helicopter (直升机) arrived to save them.
