《名词性从句作主语》语法课教学设计

《名词性从句作主语》语法课教学设计广州市花都区邝维煜纪念中学骆仕威一、教学内容简析：《人教版》教科书中语法项目主要是在一定情景中出现的。

学生在ModuleⅢ, Unit 3中学习过the Object clause 和the Predictive clause，明确了一个复合句中有多种从句存在，也对从句划分有了初步的认识。

学生学习完Module Ⅲ中Unit4 ，How Life Began on the Earth 中课文及句子，特别对含有主语从句的4个句子的中、英文理解较为透彻。

关键是要对主语从句的引导词的归纳、形式主语的使用作进一步探讨，这也是本节语法课中的重点和难点。

二、教学对象分析：该班学生已学习过the Object clause 和the Predictive clause，明确一个复合句中有多种从句存在，也对从句划分有了初步的掌握。

他们适应老师的全英教学，适应且乐于进行Pair work、group discussion等多种方式的小组合作活动，大多数学生能够借助教师的语言提示及例子提示发现、归纳新的语法现象。

中等偏下及以上水平的学生有一定的自学能力并有良好的预习习惯，他们会结合学生用书的Discovering useful structures 和附录中的Grammar 部分对语法点进行预习。

三、教学设计的基本思路：中学英语课教学语法是必要的，符合中国学生认知规律的循序渐进的语法教学能够迅速有效地帮助学生准确地理解和掌握英语。

但是语法教学本身并非目的，而是为了学生掌握和运用语言服务的。

因此教师不要把语法课搞成“满堂灌”，决不能做过多的讲解，学习语法的最好方法是在“用”中学。

所以本节课以学生为课堂学习的主体，根据“使学生理解学习过程”的原则，运用讲解、讨论、发现、阅读、练习等多种教学方法，设计本节教学。

整个过程紧扣教材，反复利用课文例句，以方便学生在熟悉基础上更好理解语言现象，在篇章理解及语言运用中发现、熟悉、掌握、应用语法现象，遵循先意义后形式、先理解后研究的原则展开本节课的教学。

四、教学目标(Purposes)：1．To help students master the use of the subject clauses;2. To enable students to conclude the introductory words of the subject clause;3. To aid students to identify and understand the subject clause in sentences and passages.五、教学难重点(Importance & difficulty)：1.主语从句的划分；2.主语从句的引导词归纳及使用；3.形式主语的使用。

六、教学媒体、教具（Teaching Aids）：Powerpoint sliding cards.七、教学过程(Procedures):StepⅠ. Leading-in1. Greeting;2. Revision:--Yesterday we learned 3 sentences with clauses in the lesson on P25—26.●What it was to become was a mystery .●What scientists think is that the earth was different .●Whether life will continue on the earth will depend on whether this problem can be solved--What are the underlined clauses?StepⅡ. Presenting1. Present the Topic of the lesson:A Lesson on the Subject Clause.2. Present 7sentences with the subject clause:●What it was to become was a mystery .●What scientists think is that the earth was different .●Whether life will continue on the earth will depend on whether this problem can be solved.●What the mice like is the rice.●How well we can learn English can be waited and seen.●Why they were late surprised everyone.●That you like English makes me very happy.3. Task 1:Group work: --What can be used to introduce the subject clause?4. Present the introductory words.主语从句可用That或WH-words (what, who, which, whoever, whatever, when, where, why , whether) 来引导,但绝不可用If 来引导.Whether life will continue on the earth will depend on whether this problem can be solved.(True)If life will continue on the earth will depend on whether this problem can be solved. (False)5. --Can we only put the subject clause at the very beginning of the sentence:Present the use of the formal subject “it”:当主语从句过长,而句子谓语及宾语或表语较短时,往往用It 作为形式主语放于句首而把真正的主语从句移到句末.6. Present the special structures and some examples of “it”:When the subject clause is introduced by what, whatever, whoever, whichever, “it” can’t be used as the formal subject.StepⅢ. Practising:1. Blank-filling exercises;1). the country should build a nuclear power station is something we must discuss.2). much water is flowing can be measured easily.3). will go to the meeting is not important.4). we need is more time.5). they are going to lay the pipes matters a great deal.6). the power station will be ready is uncertain.7). we need to control the flow of water is something I will explain.8). we must do is reduce the use of energy and use natural energy.9). It is certain fuels like coal and oil cause a lot of pollution.10). It is not yet decided and the test will be given.2. Translation:1)、是谁去机场接(meet)他还不清楚。

is still not clear.2)、他不辞而别(leave without saying goodbye)的原因仍然是个谜。

is still a mystery/ is still unknown.3)、生命在地球上能否延续取决于这个问题能否解决。

will depend on whether this problem can be solved.3. Lead students to conclude the rule from the sentences they have learned.--How do you know these are the subject clauses?Conclude the rule:Generally speaking, the clause before the real verb (句子的真正谓语) is the subject clause.4. --Now you can you recognize the subject clause in the passage?Task3: Group work: To find out the sentences with the subject clauses in the given reading material.(文章见附页)5.Task4Pair work: To make a dialogue in which there is at least one sentence with a subject clause. StepⅣ. Focusing & solidifyingSome special structures of the subject clauses:1. A subject clause can be introduced by a conjunctive pronoun that and WH-words but without if.2. When the subject clause is too long while the real verb and the object or the predictive is very short, we should put “it” as the formal subject at the very beginning of the sentence and the real subject clause at the end to keep the balance of the sentence.3. When the subject clause is introduced by what, whatever, whoever, whichever, “it” can’t be used as the subject.StepⅤ. Assignment1. More blank-filling exercises（见附页）2. Best choice exercises; （见附页）3. Find out the object clauses and predictive clauses in the given reading material.2005年3月27日。
