_____ you don't like him is none of my business.A.what B.who C.that D.whether可是为什么呢?
_____ you don't like him is none of my business.
A.what B.who C.that D.whether
可是为什么呢?

_____ you don't like him is none of my business.A.what B.who C.that D.whether可是为什么呢?
首先,这是一个主语从句,而且从句内容完整,所以要用没有实义的连接助词来引导,而不能用A和B,
其次,whether后一般不接否定的从句,如果一定要用not,应说Whether or not you like him is none of my business.
所以排除whether.
这是老师教我们时用的分析方法.
我情愿理解成,用that 是一种语言习惯.因为我看此类题时,很少用结构分析.也能十拿九稳.语言就是这样,见得多了,用得多了,你就会养成一种语言习惯,就不用问那么多为什么了.
希望你学习时不要拘泥于中式的语法分析.而是养成一种语言习惯.

主语从句
一、概述：在句子中起名词作用的各种从句统称为名词性从句。根据它们在句中的语法作用，这类从句又可分为主语从句、同位语从句、表语从句和宾语从句。
二、 几个共性问题：
1．连接方式
（1） 在由连词that, whether, if引导的名词性从句中，引导词在句中不做成分，在宾语从句和表语从句中，that可以省略。
（2） 在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中，其连接代词在句中起名词性作用，担当一定成分。
（3）在由连接副词when, where, why, how引导的名词性从句中，其连接副词在句中作状语。
2．whether和if的区别
（1）whether在引导的主语从句中可以置于句首，而if则不能。
（2）whether可以与or not连用，or not可以紧跟在whether之后，也可以置于从句末尾；if一般不能和or not连用。
（3）表语从句、同位语从句和介词宾语从句（即在系词be和介词之后），只能用whether连接，而不用if。
（4）从句是否定式时，一般用if, whether很少用在否定式从句中。
例如：I don’t care if he doesn’t come . 如果他不来，我也不介意。
The problem is whether we can carry out the plan.
问题是我们是否能实施这项计划。
三、 主语从句
1．主语从句主要有三类：
（1） 由连词that引导的主语从句。
例如：That you will win the medal seems unlikely.
你想获得奖牌看起来是不可能的。
That you are so indifferent bothers me.
你如此冷淡使我很烦恼。
That she survived the accident is a miracle.
她在事故中幸免于难简直是奇迹。
（2） 用连接代词或连接副词if, whether 引导的主语从句。
例如： Which of them escaped from the prison is still a mystery.
他们哪一个是从监狱里逃跑的，仍然是个谜。
When they will come hasn’t been made pubic.
他们什么时候来还不知道。
Whether she is coming or not doesn’t matter too much.
她来不来都无关紧要。
（3） 用关系代词引导的主语从句。
例如：What you need is more practice.
你所需要的是更多的训练。
What I want to know is this. 我想知道的就是这事。
Whatever we do is to serve the people.
我们无论做什么都是为人民服务。
主语从句可以直接放在主语位置上，也可以用it作形式主语，
而将从句放在句末（尤其是当谓语较短时）。
例如：That light travels in straight lines is known to all.
光沿直线传播，这是众所周知的事。
=It is known to all that light travels in straight lines.
众所周知光沿直线传播。
When the plane is to take off has not been announced .
飞机何时起飞还没有宣布。
= It has not been announced when the plane is to take off.
还没有宣布飞机何时起飞。
当what引导的主语从句表示“…的东西”时，一般不用it作形式主语。
错:It is a book what he wants.
对:What he wants is a book. 他想要的是本书。
如果带主语从句的句子是疑问式，则必须用it作形式主语的结构。
例如：Has it been settled who will be sent to carry out the task ?
谁将被派去执行这项任务决定了吗 ？
