在以下句中whose、what、which的作用，也就是说它们做什么成分

What do you mean?
Which do you prefer?
Whose are you going to borrow?
Which train will you take?
What time shall we meet again?
Whose umbrella is this?
要该怎么判断句子的成分呢？就以这几个句子为例能不能大概讲一下。

What--宾语 do you mean?
Which---宾语 do you prefer?
Whose --宾语are you going to borrow?
前三句都是分别作动词mean意味着...\prefer宁愿...\borrow借... 的宾语（即动作、动词的目标对象或承受者）

Which定语 +train -----（which train---合起来做宾语）will you take?
What 定语+time----（what time 合起来做时间状语） shall we meet again?
Whose 定语+umbrella----（Whose umbrella 合起来做表语） is this?
后三句都做定语，修饰后面的名词train\time\umbrella,和名词和在一起相当于一个名词短语，有在剧中担任相应的成分。第一句名词train作take 的宾语，即take a train;第二句修饰动词meet，即什么时候再见面，做（时间）状语；第三句变成陈述句就是This is whose umbrella.系动词后面作表语。
欢迎交流。OK

太懒了吧！小妹，这么简单的英语还要用问问抄？ what are you doing?i am singing. what is this?it is a act. where are you from?i am from china where shall we go?go to study in this room who is your mam?the speaking woman who are you?i am jack when can we get china?last week

what是动词mean的宾语 which是动词prefer的宾语 whose是动词borrow的宾语 which是修饰名词train所以叫定语 what time是说明动作发生的地点的所以叫状语 whose是修饰名词的叫定语
