特指是要指给别人看,在某一系列事物中说话者想要描述的东西。但是这里,construction of the first skyscraper不用你指别人也知道是第一幢摩天大楼的建造。他强调第一幢摩天楼的“建造”,对于第一幢摩天楼而言,建造只有一个。但是如果你要强调第一幢摩天楼的某扇窗户,就必须要The window of the first skyscraper 了。
关于你指的唯一的东西要特指,其实只是在江河湖海,天体之前是必须要加的。比如The moon,The pearl river delta,其他不是的。
还有在一些职位之前,虽然是唯一,但是不加the。比如He was elected monitor of our class. 班长前面是不加the的。
