这里的whose 是定语从句的关系代词,这句的先行词是a young cow or ox whose 作which的所有格,作“某(些)物的……”解,它所指代的先行词必须是物,其引导的定语从句修饰它的先行词,同时它本身在从句中作定语。 看下面的例句 The company whose name was Notcowas in Australia。那个名叫诺特可的公司设在澳大利亚追问为什么不可以用that呢
追答that本身是为了代替who(m)/which而产生的
Take the book which/that is lying on the table. The man who/that is walking on the playground is my old friend.
