3.whose的用法

whose既可指人也可指物，在从句中修饰名词作定语，相当于所修饰成分的前置所有格。它可以转化为“the＋名词＋of which/whom” 和“of which/whom＋the＋名词”的形式。 This is the scientist whose name is known all over the country. →This is the scientist the name of whom/of whom the name is known all over the country. 这就是那位全国知名的科学家。 Please pass me the book whose cover is green. →Please pass me the book the cover of which/of which the cover is green. 请递给我那本绿色封面的书。
