【自主学习，明确目标】

1. 教学目标：1）了解名词性从句的定义、种类，及其位置。

2）掌握名词性从句的语序，引导词的选择及其技巧。

2．教学重点: 熟记that, whether, if, what, which等引导词的特殊用法。

3. 易混淆点：1）whether, if的区别；2）that, what的区别；

3) what, which 的区别4) 主语从句中的主谓一致问题。

【自主学习，问题生成】

一、感受名词性从句:猜猜下列谚语的汉语意思，并判断各句中的名词性从句分别是什么从句。

1. What's lost is lost. (句意：______________________________________________ ________从句)

2. It is known to all that the earth turns around the sun. (句意：________从句)

4. Children are what the mothers are. (句意：________从句)

5. We hold this truth that all men are created equal. (句意：________从句)

二、基础知识回顾：

1. 名词性从句的定义、句法功能和分类

由连接词引导，在复合句中起____词作用的从句叫名词性从句(Noun Clauses)。名词性从句在复合句中的功能相当于名词词组, 它在复合句中能担任________语、_______语、________语和_______语等，因此根据它在句中不同的句法功能，名词性从句又可分别分为________从句、__________从句、___________从句，和_________从句。

2. 引导名词性从句的连接词，及其在句中的作用。

3. 解题方法：

1). 找出主句的谓语，确定是什么从句。

2). 分析从句的句子成分，缺什么，补什么；不缺句子成分，不缺意思，就选_______; 不缺句子成分，只缺“是否”，就选__________或if；缺主语/宾语/表语，就补连接______词，选what, who, whom, which等；缺状语，就补连接_________词，选when, where, why, how等。

3). 确定词性后，再根据句子的意思选择适当的引导词。

我的问题：（你在预习中有哪些未能解决的问题和有疑问的地方？写在下面做个备忘吧！等待课堂上与老师和同学他就讨论解决。）

【合作探究，解决问题】

探究一：观察句子，找出主句谓语，划出从句，判断从句类型。

2. 在复合句中作宾语的从句叫作_______从句。它常位于_______词或介词之后(如例4, 5)。当宾语后面还有宾补时，常用______作形式宾语，而把作真正宾语的宾语从句放到__________(如例7)

3. 在复合句中用作表语的从句叫作_______从句。它一般位于_______ 动词之后。（如例3）。

4.同位语从句一般位于fact, news, promise, truth, belief, thought, idea, information, doubt, hope, opinion, plan, suggestion等抽象____词之后，进一步解释和说明前面名词的具体内容或含义。(如例8)

4. 由what引导从句作主语时，主句的谓语动词的数一般与后面的______语的数保持一致。(如例4、5) 探究四：连接词的选用：
