Frederick Stanley Mockford created the mayday call signal in the 1920s. Mr. Mockford was a radio officer at Croydon Airport in London. He was asked to think of a word that could be used in an emergency. The word had to be easily understood by all pilots and airport workers. Much of the air traffic at that time was between London and Paris. So, he proposed the word mayday. Today, many groups use mayday to mean a life-threatening emergency. The call is always given three times to prevent mistaking it for some similar sounding words._____________________弗雷德里克?斯坦利?莫克福特于20世纪20年代创造了mayday这个紧急呼救信号.莫克福特是伦敦克罗伊登机场的无线电工作人员.他受命想出一个能用于紧急情况下的词语.这个词语必须易于被飞行员和机场人员理解.那个时候有大量的航班来往于克罗伊登机场和法国巴黎附近的布尔歇机场.所以他提出用"mayday"一词. 今天,很多机构使用这个词汇来表达生命受到威胁时的紧急情况.通常这个呼叫会被重复三遍来避免与一些近音词语相混淆.__________________________
