UNIT 2 BRIDGING CULTURES 单元整体教学设计
人教版必修二Unit 2 Bridging Cultures 第三课时
Discover useful structures教学设计
I ．教学内容
Student Book : Learning About Language ( Discover useful structures ) Workbook : Using Structures
II ．课时目标
学生通过本课时的学习，能够：
1．识别名词性从句的类别，并通过分析例句归纳其结构特点。
2．在教师的引导下探究名词性从句的用法。
3．通过改写句子、中英文互译体会名词性从句的表达效果。
4．通过实践运用巩固名词性从句的用法，学会在口头和笔头表达中恰当运用名词性从句。
III ．教学思路
教师首先让学生使用本单元阅读板块学习的长难句分析策略分析教材活动1中的名词性从句，了解名词性从句的概念和类别。
接下来让学生阅读第105页语法附录中的例句，引导他们梳理三类名词性从句（主语从句、表语从句、宾语从句）的结构特点，并归纳名词性从句中引导词的类别和作用、连词 that 的省略情况、 it 作形式主语和形式宾语的句式特点等。
此后为名词性从句的巩固和运用阶段。教师首先通过教材活动2培养学生用名词性从句整合句子的能力，并增加双向互译的环节以巩固对名词性从句的语义理解与运用实践，引导学生对比中英文句子的不同特点，提升使用名词性从句的准确性。接下来，教师通过教材活动3引导学生在篇章语境中运用名词性从句，理解其语用功能以及在篇章中黏合信息的作用。然后通过教材活动4鼓励学生运用定向半开放句式来讲述 Xie Lei 的经历，学会使用较复杂的英语句子来表达。最后引导学生使用名词性从句修改作文，培养学生在书面表达中应用名词性从句的意识，从而提升语言表达效果。
IV ．教学过程

Possible revised version :
Dear Sir / Madam ,
I ' m Xie Lei , an exchange student from China . I ' m delighted to learn that volunteer students are wanted for a Chinese painting exhibition to be held in the local art gallery . So now I ' m writing to apply for the position .
The reasons for my application are as follows . Firstly , what makes me stand out is my good command of English , which I acquired from my exposure to English from an early age . What ' s more , it ' s worth mentioning that years of being a school monitor has made me a brilliant organiser , which will really help to keep the exhibition in order . The most important factor is perhaps that my related knowledge will undoubtedly help your visitors learn more about Chinese art .
In addition , I believe my sense of responsibility will make me a very reliable volunteer . I ' d appreciate it if you could take my application into consideration .

设计说明：基于以上各环节的练习，本活动引导学生完成一个更具挑战性的任务﹣﹣使用名词性从句修改和完善作文，该活动体现了本单元语法学习的真正意义。语句松散是学生习作中的常见问题，而名词性从句能使上下文意思更为紧凑，逻辑更为严密。该活动启发学生学以致用，使用名词性从句丰富写作句式、提升表达能力。同时教师也需要提醒学生，这里只是为了突出运用从句的可能性，实际写作中可能并不需要这样高密度地使用名词性从句。至此，本节课实现了该语法项目从形式梳理、结构操练到语篇应用、口头交际与书面应用层层推进的目标。
Assignment
Finish the three exercises on page 69 in the Workbook .
Write a short passage about Xie Lei ' s experience in London using the sentences you made in Activity 4. Pay attention to the logic between the sentences and add more sentences where required . Then improve your writing using what you have learnt in this class .
设计说明：第一项作业的目的是使用教材所给练习巩固本单元的语法学习效果。第二项作业让学生将活动4的语句以书面形式呈现，这既是对课堂效果的检验，也是对名词性从句语篇功能的巩固。教师应提示学生：名词性从句在书面语中更为常见，学生在尽量多地使用名词性从句的同时，也要考虑篇章的连贯与过渡，避免一味堆砌；此外，除名词性从句外，学生在平时写作中还应多使用其他句型，使表达丰富、自然。
