Unit4 Friends forever Presenting ideas—the Use of “not only…but also…” in Partial Inversion教案 高中英语外研社必修第一册 I. 教学内容 “not only…but also…”在部分倒装句中的运用 II. 教学目标 1.介绍“not only…but also…”用于倒装句的规则； 2.介绍助动词的相关用法。 III. 教学重难点 掌握助动词的分类并能正确用于“not only…but also…”的倒装句结构。 IV. 教学过程 一、引入“not only…but also…”在写作中的常见错误形式。 1、呈现学生的微写作范文，指出“not only…but also…” 在此写作中的语法错误。 写作任务： 假设你是晨光中学的李津,下周你校将与英国友好校举办一场在线辩论赛, 辩题为网络学习英语利大于弊。 作为正方，请你谈谈网络学习英语的优势。 学生作品： Good evening, my dear teachers and classmates. I am extremely privileged to talk about the advantages of learning English online. Without doubt, the advantages of learning English online outweigh the disadvantages. Not only we can communicate with natives in real-time, but also we can have access to masses of resources online related to English. Therefore, our side believes that the advantages of learning English online outweigh its disadvantages. 错误分析： “Not only we can communicate with natives in real-time,…”未使用部分倒装。 二、观察以not only开头的倒装句，并总结部分倒装在not only句型结构中的规律。 观察例句： 1. Not only did he learn a lot from the activity but also he widened his social circle. 2. Not only shall we form a good habit of learning but also we should take positive attitude towards study. 总结规律： ① 当”not only”位于句首，且”not only…but also…” 用于连接两个句子时，助动词会前置于主语，即：not only后面的句子要部分倒装。 ②“but also” 后语序不变。 ③“but also” 后重复部分(主+助动词）可省略。 三、讲解助动词的用法和分类，突破倒装句难点。 助动词的分类： 1.情态动词 如：can/could; will/would; may/might, etc 2.基本助动词 1）构成时态 如：has done；have done 2）构成语态： 如：be done 3）构成否定/疑问 如：do not like 4）加强语气 如：I do trust you. 四、巩固练习 practice 1：Find out the auxiliaries in the sentences. 1. He is cheated by his friend. 2. He has gotten married. 3. Do you like college life? 4. He did know that. 5. She will come here. Practice2: Correct the mistakes in the sentences and simplify them. 1.
