It is an imaginary line dividing the world.这里的dividing 的作用是什么?充当什么成分?此句It is an imaginary line dividing the world.如果变成 It is an imaginary line which divides the world.术语里叫什么变化？
网友回答
It is an imaginary line dividing the world里dividing the world 是修饰line的,作定语的,非谓语动词作定语 而It is an imaginary line which divides the world.是个定语从句,which是代词,是非限定性定语从句,要表达的意思是一样的 无论是dividing the world 还是 which divides the world都在句中作定语,都是起修饰作用.
======以下答案可供参考======
供参考答案1:
非谓语动词做定语。
供参考答案2:
定语，修饰imaginary line 。可以这样去理这是一条dividing the world的imaginary line .
应该是简单句变成复合句吧。
