如何选择主语从句的引导词？
Tips: 根据句子意思，分析引导词和主语从句的 结构和关系
如果从句缺主语，指人用who，指物用what； 如缺宾语，指人用whom，指物用what； 如缺时间状语用when；地点状语用where； 原因状语用why；方式状语用how；定语 用what或which；
什么都不缺考虑 that 或whether。

令人惊奇的是…
It is a fact that……
事实是……
It + 不及物动词 ＋ that从句
It seems that… It happens that ….
好像… 碰巧…

3.培养学生寻找细微区别，揭示事物本质的能力。
学法指导：1.必须明确掌握名词性从句引导词的种类、功能、例词。
名词性从句的概念2.进一步掌握名词性从句中的：语序：在名词性从句中一律使用陈述语序。

主句
名词性从句
名词在句子中可以充当主语、宾语、表 语、同位语，但如果名词充当的成分 （主语、宾语、表语、同位语）是一个 个句子，那么我们就把它称为名词性从 句。
因此根据名词在句中所担当的成分，名 词性从句又可分为主语从句、宾语从句、 表语从句和同位语从句。（如下图所示）
名词性从句 noun clause
3.We Chinese are peace-loving.
apposition predicative

【本讲教育信息】一. 教学内容：名词性从句——主语从句与同位语从句二. 知识精讲：（一）主语从句1. 概念与引导词在复合句中充当主语的从句就叫做主语从句。
引导主语从句的连接词有that, whether, who, whom, whose, what, which, whoever, whatever, whichever, where , when , why , how Where we shall have the meeting makes no difference.我们在哪开会都无所谓。
That we were invited to a concert this evening is good news to us.我们被邀请去参加今晚的音乐会，这对于我们来说是个好消息。
2. 主语从句需要注意的问题（1）从属连词that在主语从句中不作任何成分，只起连接作用，但不能省略，并且可以用形式主语it代替，把that从句置于句末。
That he will come to the conference has excited every one of us.他要来参加会议使我们每一个人都很激动。
It is decided that the meeting will be put off till next Monday.已决定将会议推迟到下周一。
（2）主语从句常用it作形式主语，常用于以下固定句式中：①It +be +形容词（obvious, natural, surprising, wonderful, possible, likely, certain, necessary, important, strange…）+ that从句，在这类主语从句中，谓语部分常用虚拟语气，即should+动词原形。
It is necessary that one (should) master the skills of operating computers.掌握电脑操作技术是很有必要的。

高一年级班组姓名：主语从句序列号：012【自主定位】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。
【合作解疑】二.主语从句主要有三类：（1）由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省。
例如：That she survived the accident is a miracle.她在事故中幸免于难简直是奇迹。
（2）用连词whether 引导的主语从句:whether有含义(是否),在句中不做成分,不可以省。
例如：Whether she is coming or not doesn’t matter too much.她来不来都无关紧要。
（3）用连接代词引导的主语从句(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).例如：What you need is more practice.你所需要的是更多的训练。
Whatever we do is to serve the people.我们无论做什么都是为人民服务。
（4）用连接副词when, where, why, how引导的名词性从句(其连接副词有含义,在句中作状语。
)eg:Where we should leave it is a problem.When they will come hasn’t been made pubic.他们什么时候来还不知道。
三.注意点:1.it 做形式主语,而将主语从句放在句末（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。

2. That Jay Zhou will come to my city
excites everybody. 该句中主语从句是 _T_h_a_t_J_a_y__Z_h_o_u__w_i_ll_ _c_o_m_e__to__m_y__c_it_y_，引导词为__th_a_t_。 3. Whether we will travel abroad or not
What it was to become was uncertain until between 4.5 and 3.8 billion years ago… …it was not clear whether the shape would last or not. 通过观察，我们发现两句当中划线部分 的句子都在复合句中起名词的作用，因 此称之为主语从句。
2. whether与if引导主语从句 如果主语从句置于句首，不能用if
引导，此时，需用whether。但如果用 it作形式主语，而把主语从句放在句末 时，也可以用if引导。
【巩固练习】 用whether或if填空。 (1) It doesn’t matter _w_h_e_t_h_e_r_/_i_f_ he will come or not. (2) _W__h_e_th__er_ we’ll go camping tomorrow depends on the weather. (3) It was doubtful _w_h_e_t_h_e_r_/_i_f_ Tom really saw Sharon. (4) _W__h_e_th__er_ Tom really saw Sharon was doubtful.

*what 在从句中作主语
4)When we will begin the meeting is under discussion.
*When 在从句中作状语
Exercise 1:
同位语从句
名词性从句的作用相当于名词，因此主语从句、 表语从句 、宾语从句和同位语从句分别作主句 的主语、表语、宾语和同位语。
Who will win the match is still unknown.
主语从句
I want to know what he has told you.
宾语从句
The fact is that we have lost the game.

人教新课标必修三 Unit 4语法学案 语法知识----名词性从句III
学习目标：语法知识----名词性从句III学习重点：主语从句主语从句是在复合句中充当主语的从句，引导主语从句的词有连词that, whether；连接代词who, what, which；连接副词when, where, how, why等。
主语从句做主语谓语动词一般用单数。
That he will succeed is certain. Whether he will go there is not known.What he said is not true. When the meeting will be held has not been decided yet.为了避免主语显得过长，可以用it作为句子的主语，把主语从句移到句子的末尾。
It is said that President Jiang will visit our school next week.It hasn't been decided when the new restaurant will open.It is hard to understand why he failed in this examination.It is not clear how gold was found there.主语从句中需注意的问题：1. It 作形式主语和it引导强调句的比较It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。
而it 引导的强调句则是对句子某一部分进行强调，无论强调的是什么成分，都可用连词that。
被强调部分指人时也可用who/whom。
It was in the morning _____ the murder took place.It was at 7 ______ I got home. It is John ____ broke the windowIt is a pity ______ you didn’t go to see the film.It is the house _____ I live. It is the house _____ I visited ten years ago.2. 用it 作形式主语的常用结构(1) It is ＋名词＋从句It is an honor that...
