初中优秀英语说课稿《宾语从句》

初中优秀英语说课稿《宾语从句》初三英语《宾语从句讲解》说课教案本人这节课主要是带领学生复习了前面学习的一个重要语法项目--宾语从句。
宾语从句是中考的重点语法项目,通过前面的学习,学生对宾语从句有了一定的了解,但是有些同学在运用时总会出现这样那样的错误,因此,很有必要对之进行全面的复习巩固。
首先,我用多媒体投影放出了“了解宾语从句”,这样做了目的是让学生了解宾语从句是主从复合句的一种。
主从复合句是由一个主句和一个或一个以上的从句构成的。
主句是复合句的主体,从句仅仅是主句的一个成分,它从属于主句,不能独立。
从句在全句中充当什么成分,就叫什么从句。
宾语从句在全句中作宾语。
接着,我又向学生展示了本节课的学习目标及重、难点,让学生做到心中数。
然后围绕重点、难点,从三个方面进行了复习:1、由不同引导词引导的宾语从句2、直接引语和间接引语3、宾语从句中时态的变化在复习由不同引导词引导的宾语从句时,又分了三种情况:由从属连词that引导的宾语从句、由连接代词who,whom,whose,whichwhat和连接副词where,how,why,when引导的宾语从句、由从属连词whether,if引导的宾语从句。
并且又针对每一种情况进行了练习,从而使学生对宾语从句有了一个更加深刻的印象。
由于宾语从句与直接引语变间接引语联系非常密切,所以我又在复习宾语从句后添加了直接引语变间接引语这一内容,使学生对所学内容进一步得到了巩固。
最后,由学生自己归纳总结出宾语从句中时态的变化,也就是本节课的第三个重点内容。
在此基础上,又进行了综合方面的练习,使绝大数学生更好地学习领会了宾语从句,达到了本节课的教学目的。

英语从句讲解教案初中

英语从句讲解教案初中Objective: The objective of this lesson is to help students understand and differentiate between different types of clauses in English, including dependent and independent clauses, and how to use them effectively in sentences.Materials:- Whiteboard or blackboard- Markers or chalk- Handout with examples of different types of clauses- Sentence diagramming tools (optional)Procedure:1. Introduction (5 minutes)Begin the lesson by asking students what they know about clauses in English. Ask them to provide examples of sentences with clauses. Write some of their examples on the board. 2. Definition and Types of Clauses (10 minutes)Explain to students that a clause is a group of words containing a subject and a verb, and it is used to express a complete thought. There are two main types of clauses: dependent and independent.- Dependent clause: A dependent clause cannot stand alone as a complete sentence because it relies on another clause for meaning. It usually begins with a relative pronoun (who, which, that) or a conjunction (because, although, if). Provide examples and have students identify the dependent clauses in them.- Independent clause: An independent clause can stand alone as a complete sentence because it expresses a complete thought. It does not rely on another clause for meaning. Provide examples and have students identify the independent clauses in them.3. Identifying and Using Clauses in Sentences (15 minutes)Distribute the handout with examples of different types of clauses and have students work in pairs to identify the type of clause in each example. Encourage students to provide their own examples and discuss how to use them in sentences.4. Sentence Diagramming (10 minutes)If you have access to sentence diagramming tools, demonstrate how to diagram a sentence with dependent and independent clauses. Ask students to try diagramming some of the examples they have identified earlier in the lesson.5. Practice and Application (10 minutes)Provide students with a list of sentences and ask them to identify the type of clause in each one. Encourage them to provide their own examples and use them in sentences. You can also ask students to write their own sentences using dependent and independent clauses and share them with the class.6. Conclusion (5 minutes)Summarize the main points of the lesson by reviewing the types of clauses and their uses in sentences. Encourage students to practice identifying and using clauses in their writing to improve the flow and coherence of their sentences.Assessment:- Exit Ticket: Ask students to write a sentence using both a dependent and independent clause and provide a brief explanation of how they used them in the sentence.- Peer Review: Have students write a short paragraph using dependent and independent clauses and have them exchange paragraphs with a partner for review and feedback.- Homework: Assign a paragraph writing task where students must use a variety of dependent and independent clauses to create a coherent and cohesive paragraph.By the end of the lesson, students should have a clear understanding of the different types of clauses in English and how to use them effectively in sentences.。

初中定语从句语法讲解教案

教学重点:1. 定语从句的概念和作用;2. 关系词的用法及选择。

教学准备:1. PPT课件;2. 相关练习题。
教学过程:一、导入(5分钟)1. 引导学生回顾复合句的概念,让学生意识到定语从句是复合句的一部分;2. 提问:什么是定语从句?它的作用是什么?二、讲解定语从句的概念和作用(10分钟)1. 解释定语从句的概念:在复合句中,修饰某一名词或代词的从句叫定语从句;2. 强调定语从句的作用:定语从句的作用是修饰先行词,起到形容词的作用;3. 举例说明:如“The book that you gave me is very interesting.”中,“that you gave me”是定语从句,修饰先行词“the book”。
三、讲解关系词及其用法(10分钟)1. 介绍关系代词:that,which,who(宾格whom,所有格whose);2. 介绍关系副词:where,when,why;3. 讲解关系词的用法:关系词在定语从句中作主语、宾语、表语等成分;4. 举例说明:如“The book that you gave me is very interesting.”中,“that”作主语;“The place where we met is near the school.”中,“where”作地点状语。

从句从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。
(参见以下各条)3、各从句在句子中的位置以及用法:(1) 表语从句:在句子中作连系动词的表语的从句,它位于主句中的系动词之后。
例如:That is why he did not come to school yesterday. / It is because you are so clever.(2) 宾语从句:在句子中作及物动词或介词的宾语。
①基本形式:(主句+)连词+从句主语+从句谓语+...②关于宾语从句连词的选择:若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;若从句来源于一个一般疑问句,连词则用if 或whether;若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)例如:They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。
) (从句本来就是陈述句)/ I wonder whether I should saysomething for him to the headmaster. (我不知道是不是该为他在校长跟前说点什么。
) (从句来源于一般问句Shall I say something for him to the headmaster?)/ He asked mewhere he could get such medicine. (他问我在哪儿能搞到那样的药。
) (从句来源于特殊问句Where can he get such medicine? )③宾语从句的时态问题:如果主句是现在时,从句则用现在某一时态,甚至可以用过去时;如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。
如:I think Iwill do better in English this term. (我想本学期我的英语会学得好点。
) / The teacher askedthe boy if the earth is round. (老师问那个男孩地球是不是圆的。
)④下列结构后面的从句一般也作为宾语从句看待:be sorry / afraid / sure / glad +that从句,如:I’m sorry I’m late. (对不起,我迟到了。

)(3) 状语从句:在复合句中作状语,其位置可以在主句前或主句后。
状语从句可以分为时间、地点、原因、目的、结果、比较、让步、条件等几种。
状语从句由从属连接词引导。
时间状语从句通常由when ,as ,while, after, before, since, as soon as ,since, till (until), while, whenever等引导。
时间状语从句一般放在句首或句尾,特别注意,时间状语从句不允许使用将来时,而应该用现在时替代。

)地点状语从句通常由where, wherever等引导。

)原因状语从句通常由because, since, as等引导,一般放在句首或句尾。
如:He went abroad because his father had found a good university for him. (他出国了,因为他父亲给他找了一所好大学。
)目的状语从句通常由so that..., so...hat..., in order that...等引导,往往放在句尾,从句中通常含有can / could / may / might等情态动词。
如:He got up earlier so that he could catch the first train. (他起身更早为的是赶上第一班车。
)结果状语从句通常由so that..., so...that... 等引导,放在句尾。
结果状语从句一般表示已经发生的事情,故多为过去时态。

(4) 定语从句:在复合句中作定语用修饰句子中某一名词或代词的从句叫定语从句。
①定语从句的位置:放在名词或代词的后面。
如:The man who has an umbrella in his hand ismy uncle. (手上抓了一把雨伞的人是我的叔叔。
)②语法术语的改变:被修饰的名词或代词称为先行词;引导定语从句的连接词称为关系词,其中that、which、who称为关系代词,where、when、how称为关系副词。
③关系代词或关系副词的作用:关系代词who、whom和whose指人,分别在从句中作主语、宾语和定语。
which指物that多指物, 有时也指人,它们在从句中可以作主语或宾语。
定语从句中关系代词作从句宾语时可以省略。
This is the thief (that/who/whom) we have been looking for these days. (这个就是我们近日一直在找的小偷。

)④限制性定语从句和非限制性定语从句。
限制性定语从句在句中不能省略,否则主句意思就不完整。
非限制性定语从句和主句之间往往用逗号分开,这种从句是一种附加说明,如果从句子中省去,也不致于影响主句的意思。
如:She spent the whole evening talking about her latest book, which none of us had heard of. (她一个晚上都在谈论她最近的书,我们一个人都没有听说过那本书。
)[注解]1、关系代词只能用that的情况:当先行词是指事物的不定代词(all, anything等),或先行词部分含有最高级,或含有序数词时,不能用其他的关系代词,只能用that. 如:All that Lily told me seems untrue. (Lily告诉我的话似乎不真实。
) / Can you give me anything that has no sugar inside?(能不能给我点里面没有糖的东西?)/ This is the first two-story bus that runs in our city. (这是第一辆运行于我市的双层公交车。
)2、关系代词在从句中作主语时一般用who(指人)、that(指物),而不用that指人或用which指物。
如:Do you know the woman who is weeping in the corner? (你认识那个在角落里哭泣的女人吗?) / Do not tell me any words that have nothing to do with me. (跟我无关的话,请一个字也不要说。
)3、关系代词作从句的宾语时,常用which或whom,较少使用that或who,而且,关系代词常常省略。
