When a light passenger plane flew off course some time ago, it crashed in the mountains and its pilot was killed.
The only passengers, a young woman and her two baby daughters, were unhurt. It was the middle of winter. Snow lay thick on the ground. The woman knew that the nearest village was miles away. When it grew dark, she turned a suitcase into a bed and put the children inside it, covering them with all the clothes she could find. During the night, it got terribly cold. The woman kept as near as she could to the children and even tried to get into the case herself, but it was too small.
Early next morning, she heard planes passing overhead and wondered how she could send a signal. Then she had an idea. She stamped out the letters 'SOS' in the snow. Fortunately, a pilot saw the signal and sent a message by radio to the nearest town. It was not long before a helicopter arrived on the scene to rescue the survivors of the plane crash.
Summary:
A light plane crashed in the mountains by accident causing the death of the pilot. A mother and her two children were the only passengers, and fortunately, they got unhurt. All this happened in middle of Winter, when there was thick snow on the mountains. It was far from the village, hopelessly to get any emergency help. The mother managed to make a suitcase bed for her children and did everything she could to keep them warm in the night. Next morning, she heard passing planes overhead, an idea rushed her mind. She stamped the letters "SOS" in the snow, and the most pleasurable result was that a pilot noticed the signal and found people to help them. It was not long before a chopper came and all the passengers were rescued.
Words & Expressions:
SOS:一直以为这三个字母是单词缩写，比如, Save Our Souls, Save Our Ship 等等。原来只是恰巧摩斯无线电报编码中S和O，是最容易发送和识别的字母，只要敲击“…---…”（S.O.S）即可发出呼救信号。在此之前，欧洲无线电呼号字母“CQD”作为船只遇难信号（可以解释为"Come Quickly, Danger"）。现如今，SOS逐渐成为国际通用公认的海上船舶呼救信号，也成为在海域之外流行的求救信号。
