初中定语从句教学设计李海鸥邵原二中一、概述本节课要讲授的是九年级英语中的定语从句。
在初中阶段,定语从句并不是教学重点内容。
对于初中生来说,这一语法现象比较复杂和概念化,不容易理解和准确运用,大纲只要求学生具有初步的定语从句知识。
所以教学难度较大. 鉴于以上情况,我在教学中尽量采用直观的方式演示不容易理解的概念,锻炼学生用英语直接思维,交际和解决问题的能力。
我运用“学中用,用中学”的教学理念,让学生在“谈论熟悉的同学,猜谜语”之类的真实语境中尽快融入课堂学习中,理解、归纳和应用有关定语从句的知识。
我还让学生在完成练习的过程中进一步巩固所学内容。
此内容需要一个课时来完成。
二、教学目标分析1. 知识与技能①了解定语从句的概念及基本用法;②区别并正确使用关系代词who, which, that.③了解关系代词与先行词之间的位置关系。
2.过程与方法①能在交际中正确,恰当地使用定语从句;②能灵活,恰当,适度地表达自己的观点。
3.情感态度与价值观①激发学生的学习兴趣,培养学生的探究精神;②增进师生了解,增强情感交流;③通过谈论自己的喜好,培养乐观向上的生活态度;④学习正确评论人与物,形成正确的审美观。
三、学习者特征分析经过两年多的学习,九年级的学生已具有一定的英语综合能力,也积累了一定的词汇.定语从句在七年级教材中就已经出现过,只不过当时没有要求学生能正式学习和掌握.所以对于九年级的学生来说,理解由关系代词that和who引导的定语从句不会太难,但由于我校学生大多数是农村来的,英语基础相对薄弱,我们在教学中不能过多、过深地展开。
本节课的授课对象是本校九年级某个班,学生的英语水平不详,课前没去接触和了解学生,因此,我在设计本节课时,尽最大可能面向全体,兼顾不同层次的学生,鼓励他们大胆实践,勇于探索。
四、教学策略选择与设计1. 师生互动策略:请一位学生去描述另一位学生,然后教师找出所描述的学生,并将其描述的句子书写在黑板上备用。
2. 猜谜语策略:教师呈现一些用定语从句写成的谜语让学生猜测,然后启发学生总结并说出which和who在定语从句中的用法区别。
3. 做调查报告策略:通过做调查让他们表达出完整的含有定语从句的句子来。
加强巩固,在表达过程中,学生的语句会有较多扩展,教师可以走到各组中间给予适当指导。
五、教学资源与工具设计1.本课教材;2.拓展资源:PEP教材三年级Unit 6 I like music that I can dance to3.教学环境:多媒体、VCD、幻灯片、Flash动画、录音机六、教学过程步骤1:师生互相了解(语言点:who, that在定语从句中的用法)(1)教师让学生用英语描述一位同学,教师则根据学生的描述寻找这位学生以这种方式主动与学生相识。
T: I’m very happy today to meet you here, I hope you’ll like my lesson.Actually, this is the first lesson I give you. So would you like to introduce someone in your class to me?Ss: ( a little excited ) Yes!T: Remember, when I call your name, please don’t move. Other students will describe you in English, and I’ll try to find you quickly. Now, let’s try the first one. Who is….?(2)教师边听不同的学生描述边寻找被描述的学生,同时,适当板书学生所说的描述人物的话语,如:Carmen is a girl.She is very tall.She is sitting in the back row.She has long hair.She wears a pair of glasses.(3)教师找到第一位被描述的学生之后,请学生注意黑板上的句子,启发他们将这些短句连成长句。
教师先示范用定语从句中的关系代词who, that连接这些句子,然后让学生总结规律并模仿将黑板上的句子用关系代词连起来;学生再用定语从句继续描述其他同学,以此帮助教师找到更多不认识的学生。
T: Look, there are so many short sentences on the blackboard, Can you join them together to make a longer sentence?S1:Carmen is a girl, and/ but she is very tall.T: Good, Any other ways?S2: Carmen is a tall girl.T: Yes, that’s a better way. what else?…S5/T: Carmen is a girl who is very tall.(教师擦掉第二句的主语she,替换为who) T: And we can also say “Carmen is a girl that is very tall”. (在who旁边加上that).We use “who/ that” clause to describe a girl. Now, can you join the first sentence with next three sentences. Just like I do?Ss:…….T: Let’s go on the game using “Someone is a girl/ boy who/ that…”设计意图:这一设计自然地将学生带入到了学习情境中,可以有效减轻学生们的学习焦虑感。
这种师生互动也容易快速消除师生之间的陌生感。
在导入定语从句时,我没有先将语法概念告诉学生,而是直接呈现定语从句的用法,不仅直观清楚,省时高效,也锻炼了学生直接用英语思维的能力和运用所学语言的能力。
步骤2:猜谜语(语言点:which, that 在定语从句中的用法)(1)教师呈现一些用定语从句写成的谜语让学生猜测,然后启发学生总结并说出which 和who在定语从句中的用法区别。
T: Just now, you introduced some of your classmates to me, thank you very much.Now, I have some riddles. Would you like to have a try?Ss:Yes, of course.T:(用小黑板逐一呈现句子)what is the day which/ that comes after Monday?Ss: Tuesday.T: Yes, Easy, huh? What is the vegetable which/ that can be made into French fries?Ss: PotatoT: What is the fruit which/ that we often eat in summer?Ss: Watermelon… Apple…T: It’s watermelon. Here comes the most difficult one. What is the animal which/ that can always be found in baseball games?Ss: …A dog?...T: No, it’s a bat. Baseball bat! It’s just a joke. But can you tell me why we use “which” or “that” instead of “who” or “that” in these sentences?Ss: Day, Vegetable, Fruit, Animal.(2)教师用小黑板或多媒体演示主句与定语从句修饰和被修饰的关系,并请学生仿照这些句子用which和that 创编一些新谜语,让全班共同猜测,教师给予必须的指导。
(学生资料见文后附件第1题)设计意图:学生通过对比大黑板上和小黑板上的两类句式,不仅能发现which和who 的用法和区别,达到快速理解和运用定语从句的目的,也进一步增加了探究所学语法的兴趣。
创编谜语活动还为学生提供了一定的发挥和想象空间,并由此开始了下面的连句活动。
步骤3:看图片谈论人与物(语言点:练习用who, which或that将短句连成定语从句,了解主从句的位置关系)(1)教师呈现一些标有文字注释的图片,引导学生将图片上的短句连成定语从句,并用动画效果来显示正确语句。
然后引导学生进行语法归纳。
T: Ok, follow me, Let’s have a look at some pictures. And please try to join two sentences into one sentence, using “who”, “which” or “that” (showing pictures)(1) The baby is Jack. (2) The baby is wearing red trousers. Ask: which baby is Jack?S1/T: The baby who is wearing red trousers is Jack.(1) The woman is a teacher.(2) The woman lives next door. Ask: Which woman is a teacher?S2: The woman who/ that lives next door is a teacher.(1)The dress is new.(2) She is wearing it. Ask: Which dress is new?S3: The dress which/ that she is wearing is new.(1) I like travelling to places.(2) The places are very beautiful. Ask: Which place do I like travelling to?S4: I like travelling to places which/ that are very beautiful.现在请同学们根据上面的例句归纳出定语从句的概念,以及用法。
