Unit 2 Bridging CulturesLearning About Language Period 2教材分析本套教材选择性必修一第五单元学习了主语从句，本册第一单元学习了表语从句，本单元在此基础上复习这几种名词性从句。
在句子中起名词作用的句子称为名词性从句（noun clauses)。
名词性从句在复合句中能充当主语、宾语、表语、同位语等成分，根据上述不同的语法功能，名词性从句又分为主语从句、宾语从句、表语从句和同位语从句。
宾语从句是初中阶段要求掌握的内容，此外，同位语从句在选择性必修阶段不要求掌握，因此暂未涉及。
教学目标在本课学习结束时，学生能够：1. 理解名词性从句在句子中的功能，并认识到这一语法范畴包括之前学过的主语从句、表语从句、宾语从句，以及没有学过的同位语从句；2.根据句子的意义作出选择，确定名词性从句的引导词；3.创造性地运用名词性从句结构进行表达。
教学重难点【教学重点】系统掌握名词性从句的用法。
【教学难点】指导学生尝试通过拓展语法规则，书面练习和半开放口语输出来学习语法。
教学过程Step 1 Lead in1. Read and group the sentences.2. Underline the noun clauses. What is the function of each noun clause in the sentences?设计意图：给句子分类，分析课文中的句子，完成活动1，引出名词性从句的概念。
Step 2 Exploring the rules1. Some key points.2. Summary.3. Tips on choosing the linking words.设计意图：引导学生思考如何确定名词性从句的引导词，师生一起通过讨论得出结论。
Step 3 Applying the rules1. Complete the sentences with the correct linking words.2. Combine each pair of sentences using the words in brackets.3. Complete the passage with A-D from the box. What other things do you think might attract international students to China?设计意图：让学生系统学习名词性从句的用法并巩固，进一步体会名词性从句的表达效果。
