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)3. Don’t put off till tomorrow what should be done today. (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。
