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 sire raft intended to revolutionize travel and shatter speed records was destroyed during its maiden flight on Saturday after a booster rocket carrying it aloft 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"首次的；"veer"为"to turn aside from a course, direction, or purpose"转变；"tumble"为"move or rush in a headlong or uncontrolled way"翻腾。
