教材分析 本节课的主要内容为教材Language Practice 和Vocabulary板块，针对强调句型和本单元的重点词汇。学生通过一学期的学习对于英语基本时态和基本句型构成已经有所了解，本单元在以往学习基础上，学生了解强调句型的形式并在不同时态和语境中灵活运用。单元重点词汇来自本单元听力和阅读材料，教师可进一步讲解并组织学生练习、检测，夯实所学内容。
学情分析 学生经过初中阶段的英语学习，对一些英语语法现象虽然也有了一定的认识，但是不够深入，与此同时，这些碎片化语法知识并没有形成知识体系，也会影响到学生对语言的理解和运用。因此，怎样帮助学生搭建起知识的结构并理解它们内在的联系，从而能更准确地运用是教师在教学中要重点思考并努力去解决的问题。对于词汇学习，教师要注意情景创设，帮助学生掌握词汇的运用。

Step 1: Lead in Watch a video. The teacher plays a video about the Wandering Earth and presents this sentence: The Wandering Earth II creates a milestone for China’s science fiction film. Then change it into an emphasis: It is the Wandering Earth II that creates a milestone for China’s science fiction film. Watch the video and conclude the basic structure of emphasis. 通过视频导入的方式激起学生的学习兴趣。
Step 2: Presentation 基本结构. The teacher analyzes the sentence: It is the Wandering Earth II that creates a milestone for China’s science fiction film. 强调主语: It is the Wandering Earth II that creates a milestone for China’s science fiction film.. 强调宾语：It is a milestone that the Wandering Earth II creates for China’s science fiction film. 强调状语：It is for China’s science fiction film that the Wandering Earth II creates a milestone. 强调句VS状语从句. The teacher presents some sentences and ask students to fill in the proper conjunctions: It is in Beijing that she grows up. It is Beijing where she grows up. Attention: 把句子中的It is/was...that/who删掉，句子意思完整，则为强调句；反之则为状语从句。 do/does/did强调谓语 普通句：I called you last night. 强调句：I did call you last night. 普通句：We need you. 强调句：We do need you. 普通句：He loves the girls. 强调句：He does love the girl. Attention: 1.过去时用did，三单用does，动词原形用do。2.do/does/did后面的动词用原形。 强调句的一般疑问句。 It was Guo Fan who directed the Wandering Earth II. Was it Guo Fan who directed the Wandering Earth II 结构：Is/was it+被强调部分+that/who+其他 强调句的特殊疑问句。 It was in the theater that I watched the film. （对划线部分提问） Where was it that you watched the film 结构：特殊疑问词+is/was it+that/who+其他 （特殊疑问词：who, what, when, where） 强调句的其他句型。 It is/was not until+被强调部分+that “直到...才” eg: 强调句：It was not until I met you that I knew the truth. 倒装句。 eg: Only in this way can we solve the problem. 感叹句。 eg: What a beautiful girl!/How fast he runs! Get familiar with the basic structure: It is...that/who... Know the difference between emphasis and adverbial clause. Pay attention to the three situations where the predicate is emphasized. Master the structure of general question: Is/was it+被强调部分+that/who+其他 Master the structure of special question: 特殊疑问词+is/was it+that/who+其他 Know other forms of emphasis: It is not until...that.../倒装句/感叹句 利用学生感兴趣的电影作为导入，激发学生的学习欲望，让学生初步熟悉强调句的结构。 通过比较强调句和 状语从句，帮学生弄清楚易混淆点，更好的掌握强调句。 通过比较普通句和强调句，让学生更清清晰地认知do/does/did在强调谓语时的不同。 Be？ 还是实义动词？ 通过句式变换的方式，让学生掌握不同句型的强调句。
