学员疑问: 老师,下面这个句子的on which to base future prosperity怎么理解呢?
At a time when many states will struggle with labor shortages because of modest population growth, Arizona has a priceless chance to build a populous, hardworking and skilled workforce on which to base future prosperity.
老师解答:on which to base future prosperity是一个紧缩的定语从句修饰workforce,完整的表达为a workface on which Arizona can base future prosperity。句意:在许多州因人口增长缓慢而面临劳动力短缺的时候,亚利桑那州却拥有一个宝贵的机会,可以建立一支为未来的繁荣打下基础的人口众多、工作努力、技能娴熟的劳动力队伍。
点评分析: 有时候,由于表达的需求,可能会使用省略的形式表达句意。
