Grammar——

Appositive Clause 授课教师：王

虹

一、教学目标：（Teaching aims and demands）: 1) To review the knowledge of the Noun Clause that they’ve learned

2) To master the usage of The Appositive Clause 二、

教学重点（Teaching important points ）: 1) To understand the concept of The Appositive Clause 2) To master the usage of the Appositive Clause 三、教学难点（Teaching difficult points ）: 1) How to help students to recognize the Appositive Clause correctly 2)How to choose the conjunctions in the Appositive Clauses

四、教学方法（Teaching methods ）: 1) Task – based teaching(任务型教学) 2) Discovering , discussing and summarizing（发现法、讨论法与归纳法）

五、教学步骤（

Teaching steps ）

Step 1. Revision(复习) We have learned 3 kinds of Noun Clauses, Can you tell me what they are？Now here we have 3 sentences for you.

1

1.

That smoking is harmful to our health is a fact.（主语从句）

2.

I can't understand why you are late again.（宾语从句）

3.

My suggestion is that we should go there by train.（表语从句）

Step 2 .Discovering useful structures. （判断划线部分成分）

请同学们观察下面的句子中划线的部分，思考它们在句子中的作用以及所作的成分。

1

Liu XinYang, our monitor, is a handsome boy. 2.

Miss.Fan, our headteacher, is very kind to us. 3

The TV play, San Sheng San Shi, has become a hot topic. 通过师生的观察、分析，和总结，我们理解了什么是同位语以及同位语的作用是对它之前的名词起解释说明的作用。

Step3.

Discovering useful structures.（读句子，注意划线句子前的名词）

1. The news that we won the game is exciting. 2. I have no

idea when he will come back home. 3. We all know the truth that nothing is more important than health. 讨论、分析、总结出什么是同位语从句，以及它的作用。同位语从句是做名词的同位语，并对名词起进一步解释、说明的从句。

被同位语从句所解释说明的名词一般是有一定内涵的抽象名词，如：fact、idea、reason、thought、doubt、news、decision、information……等抽象名词

Step4. The conjunctions

2

1.The news that our team won the first prize excited all of us. 2 .The fact that many girls are on a diet worries their parents . 3.have no idea when he will come back. 4.The question who should go abroad required consideration. 5. He must answer the question whether he agrees to it or not. 6.I have no impression how he went home , perhaps by bike. 分析以上句子中引导词所充当的成分，总结出：

1. 如果同位语从句意义完整应用that引导同位语从句，

that 在从句中不充当任何成分，无任何具体意思，一般不省略。

2. 除

that外，

其余连词在从句中都具有各自的意义或成分，另外if 不可以引导同位语从句。

引导同位语从句的连接词：1. 从属连词

that（无实际意义，但不能省略）；whether

2. 连接代词

who、

what、

whose、

which （在句中充当主语、宾语、表语和定语）

3. 连接副词

when、

where、

why、

how(在句中作状语).

Step5 注意事项：

1.同位语从句有时可以不紧跟在它所要说明的名词后面，而是被别的词隔开，这种从句叫分隔式同位语从句。例如：

Word came that their team had won. News came from the school office that

Bai JingYi had been admitted to Beijing University. 2.表示“建议、命令、要求”等的名词（如suggestion,、advice、order、

3

request等）后接同位语从句时，从句用虚拟语气，从句的谓语动词常用“should+动词原形” 结构，should 可以省略。例如：

1. My suggestion is that we should go(go) there by train.

2.Our teacher gave advice that we should make use of

(make use of) every chance to speak English. 3. 当doubt 作名词用于肯定句中，其后的同位语从句引导词用whether; 如果是否定句/疑问句，则用that.例如：

1.There is some doubt whether our team will win the football match. 2.There is no/little doubt that they will agree with you on this matter. 若同位语从句的意义不完整，需要有“是否”的含义时，应用whether；如果同位语从句意义不完整，需要有“谁”，“什么时候”，“在哪里”，“为什么”等含义时，分别可以用who 、when 、where、why等连词引导。

Step6 Summary 1.同位语从句跟在名词后面，进一步说明该名词的具体内容。同位语从句常跟在名词

idea、fact、news、hope、thought、

suggestion等抽象名词之后；

2.连接词that不能省略,无意义无成分；

3.用whether而不用if引导同位语从句；

4.连接代词who、which、

what在从句中作主语、宾语、表语或定语;

连接副词where、

when、

why、

how在从句作状语。

Step 7. Practice (练习）

名词性从句是高中阶段一个非常重要的语法项目，本节课我们使用多媒体教学，首先复习了主语从句、宾语从句以及表语从句，然后师生结合图片以及大量的例句一起探讨学习了名词性从句中的同位语从句，了解了同位语从句的概念、作用、注意事项以及做题过程中对于连接词的选择。对于本节课的讲解，教者尽量使课堂有趣、详细、通俗易懂，通过举例、图片等方式，调动学生积极性，让学生对比分析、练习归纳，最后形成summary，使每一位同学都熟练的掌握了同位语从句的用法，以及做题技巧，达到了预期的授课效果。
