"Mayday"是国际遇险信号,通常用于船舶、飞机或其他交通工具在紧急情况下发出求救信号。在正式场合,"Mayday"前面通常会加上以下几种说法:
1. "Mayday, Mayday, Mayday"(重复三次)——这是最基本的遇险信号,用于表示最严重的紧急情况。
2. "This is [name of vessel/aircraft], this is [name of vessel/aircraft], Mayday, Mayday, Mayday" ——在发出信号时,通常会先报出自己的名称。
3. "Mayday, Mayday, Mayday, [brief description of the situation]" ——有时会先简要描述遇险情况,以便接收方迅速了解情况。
例如,一艘船在遇险时可能会这样发出信号:"This is the SS Titanic, this is the SS Titanic, Mayday, Mayday, Mayday, we have hit an iceberg and are taking on water."
