解析 新闻的结构是：事件+细节+结果。在听第一段时就可以知道What’s happening．“The first prototype of an sircraft intended to revolutionize travel and shatter speed records was destroyed during its maiden fight on Saturday after a booster rocket carrying it a loft veered out of control and tumbled from the sky．”其中“shatter”为“to break or burst suddenly into pieces，as with a violent blow”；“maiden”为“earliest，first”主要的；“veer”为“to turn aside from a course，direction，or purpose”转变；“tumble”为“fall or roll end over end”颠倒。
