初中英语七年级（上）教学案例皈大中学教师程振松通过本单元的学习，使学生掌握形容词性物主代词、数词、以及名词的复数形式的用法。本单元的日常交际项目是“确认所属”（Identifying possessions）。该项目与语法教学内容相一致。语音学习元音字母 Oo 在重读开、闭音节中的读音与相应的拼读规则。词汇学习掌握：excuse, me, but, come, come in, mum, friend, brother, nice, to, meet, child, children, welcome, our, these, they, good, those, boat, hill, tree, their, much, very much, all, right, all right,日常交际用语：Is this your/ my/ his/ her pencil-box? Yes, it is. / No, it isnt.Here you are. Where is my? Welcome to our home. Who am I? Do you know? What number is Jims bus? Come in, please. These are my friends. Kate and her brother Jim Theyre their books. Thats all right. Thank you very much. What are these/ those? Theyre etc. Its very good.Are these / those they English books? Yes, they are. / No, they arent语法项目1) 运用these, those和 they。2) 运用 my, your, his, her和 its（ 名词性物主代词 ）3）数词以及名词的复数形式。教学建议教学内容分析本单元教学的核心内容是"确认物主"，即物品归谁所有。本单元交际项目与语法项目自然遥结合起来。主要体现在"确认"与"物主"的结合，"数词"与"名词复数"这一语法项目的结合。关于“物主代词”和“数词”的学习，本单元是前面几个单元深化，教学时重点要放在操练上，尽量避免直接的、过多的从概念、语法上引入。授“名词的复数形式”，这一语法项目时，教师要大介绍一下名词的概况及其重要性。名词复数，单数间的转化也很重要。教学中，要尽可能通过大量的练习，让学生自己总结规则，通过练习，巩固成果。一句话精讲多练。与名词复数相呼应，本单元这出现了几个复数的代词these, those, they，及系动词are正式引入，由于刚刚接触到复数这一要领，再加上对英语词类理解较少，很多学生还不能区“名词复数”与“代词复数”这两个概念。往往在把代词变复数时，也按名词规则处理，常会出现的错误要及时加纠正。本单元还首次出现的听力训练这一新内容，听力材料与数字等所学内容有关，通听力训练可以激发学生学习英语的兴趣，教师要重视这一部分内容。德育分析1老师开始上课前询问："Who's on duty today?"培养学生关心集体，为班级服务的意识。2把新朋友介绍给已认识的亲人或朋友，体现人与人之间团结互助，积极友好的氛围。口语训练本单元涉及名词单、复数问题和与此相关的形式变化（如 are 的使用）。名词的复数形式并不难理解，但是要让中国学生的头脑中确立起这种变化意识，则需要一段时间的强化训练，需要对学生进行较多的机械性操练，以便在口头上巩固这些形式变化，为进一步的交际性操练做准备。在刚开始本单元的教学时，教师应有意识的用已学过的表示物品的名词，进行复数变化。并进行多样的替换练习，如：This is a car. These are cars. That is a desk. Those are desks.Is this a chair? Are these chairs? Is that a pen? Are those pens?听力训练从本单元开始，安排有语境的听力训练，教师应精心设计好听力活动，引导学生迈出掌握听力技能的第一步。1）教师应帮助学生克服思想顾虑，排除紧张情绪，增强听懂的信心。2） 学生应当先看一看图画或问题，把情景记在心里，使学生预先明确听的目标。3） 在听的过程中，学生的注意力要集中在内容上，不要集中在单词上；要集中在大意上，不要集中在细节上；要集中在正在听的内容上，不要集中在已听过的内容上。首次成功可能意味着接连不断的成功，因此，教师有责任使每个学生（包括学困生在内）都要有成功的体验。笔头训练笔头训练要特别注意纠正语言形式方面常见的错误 如：Are this her boats? （听写中易出此类错误）Those a my pens. （缺少句子结构意识）They are his banana.（忽略了复数形式）They are your boxes （忽略了-es 的形式变化）教师可以采用必要的措施逐步减少此类错误。如：让学生把自己完成的句子写在黑板上，由其他学生指出错误，教师用醒目的字体或符号予以纠正。目的是提高学生自觉使用语言的能力。本单元练习册第23课练习4是汉译英的练习。学生常犯的错误是易受母语的影响， 在翻译“我的鞋子在哪儿？”时，常会丢掉动词(are)。书中提供了图解对比英汉目的是提高学生自觉使用语言的能力。Here you are. 给你两人对话时，如果把某物给对方，一般说：Here you are.或 Here it is. 意为“给你”。如果给对方的是一件东西时说 Here you are. 也可以说 Here it is. 如果给对方的东西为复数时只能说：Here you are.另外，Here it is. 强调所给的东西。It 往往代替上文中提到的东西，也就是说，表示所给的东西是原物。- Where is my ruler? - Oh, it's here. Here it is.Here you are. 强调所给的人。因此，在使用 Here you are. 时，所给的东西可以是原物也可以是原物的代替物。如：- Can I borrow your bike? - Certainly, Here you are.-My pen is lost. - Here you are. Use mine.在不同的情景或不同的上下文中，Here it is和Here you are有着不同的理解。（1）购物时，售货员说“Here you are.”表示“给你”。（2）乘车到站时，司机说“Here it is.”表示“到站了”。（3）寻物，自己发现时常用"Here it is."。寻物，别人发现时给你常说“Here you are.”（4）乘车到站，自己可以说“Here we are.”（5）当别人向你借书或其他东西时，你可以说“Here you are.”All right, That's all right和That's rightright是一个形容词，它的基本含义是“正确的，对的”。与其构成三个常用短语：All right. That's all right. 和That's right. 虽然在形式上相似，但其具体的含义和用法却大相径庭。1） All right的用法主要有三种。（1）表示同意对方的建议或邀请，意为“行，好吧；可以，不错”等。例如：-Let's go to the zoo. 让我们去动物园吧。-All right (=OK). 好吧/行。（2）用在系动词be(am, is, are)之后，表示健康状况，意思是“健康状况良好”，相当于“fine”或“well”。 例：-How is your mother? 你*的身体好吗？-She's all right, thank you. 她很好，谢谢你。（3）表示“一切顺利，令人满意”。例如：I hope everything is all right. 我希望一切顺利。2）That's all right主要也有三种用法。（1）对别人致谢的回答，意思是“不用谢；别客气”，其含义相当于That's OK. / Not at all. / You're welcome等.例如：-Thank you very much, Lily. 谢谢你，莉莉。-That's all right(OK). 不客气。（2）对别人致歉时的回答，意思是“没关系；不介意”，其含义相当于It doesn't matter.或Never mind. 例如：-I'm sorry I'm late for school.对不起，我上学迟到了。-That's all right. 没关系（不要紧）。（3）在海关、哨卡等场所，检验人员对出入人员的证件和包裹检查后，发现无可疑情况，常说That's all right, 其含义是“可以；没有问题”。例如：-Can I see your ID, please?可以看看你的身份证吗？-OK. Here you are. 行，给你。-That's all right. Thanks. 没问题，谢谢。3) That's right的用法只有一种。这里的right意思是"正确的；对的"，它主要用于表示对某一事物的肯定，即同意对方的观点或意见。在口语中，可直接用right作答。例如：-I think she's a teacher. 我想她是一名教师。-That's right. 对。单数句变复数句子六要素：1主格人称代词要变成相应的复数主格人称代词，即I-we/ you-you /she, he, it - they. 如：She is a girl. - They are girls.2 am, is要变为are. 如： I'm a student. -We are students.3不定冠词a, an要去掉。如：He is a boy. - They are boys.4普通单数名词要变为复数形式。如：It is a cat. - They are cats.5指示代词this, that要变为these, those。如：This is a book. - These are books.6man, woman名词作定语修饰可数名词时，要在"数"上与被修饰名词保持一致。但其他名词修饰名词表示"性质"时，不作变化。如：He is a man doctor. - They are men doctors.This is an apple tree. - They are apple trees.教学设计方案Lesson 21, 22 教学设计方案( 一课时或两课时 )教学目标：1）让学生学会运用：my, your, his, her and its。2) 数词的学习以及名词的复数形式。教具：录音机，媒体，数字图片，投影仪。教学步骤：Step 1 Revision1) Revise Is everyone here today?
