三、教学过程
学习活动 效果评价
◆Step 1　Lead-in 1.Play a 2-minute video clip containing diverse scenes (a thrilling sports game,a beautiful natural landscape,a funny comedy scene).Pause the video at key moments and ask students to express their feelings immediately. 2.Divide students into groups for a “Quick Exclamation” competition.Ask them to use any exclamatory sentences (they can recall from prior knowledge)to describe the scenes in the video.Invite representatives to share their sentences,like “Wow,how exciting the game is!” or “What a beautiful view!” Write some sentences on the blackboard. 3.After the sharing,guide students to observe the sentence structures they used,naturally introducing the topic:“Today,we'll systematically learn how to use what and how to make exclamatory sentences.” 通过观察学生的分享,能判断其对感叹句的初步理解与运用能力,针对表达不准确或不熟练之处给予及时纠正和指导。
设计意图:借助多样化的情境激发学生兴趣,自然引入感叹句的运用场景,让学生在真实感受中初步体会感叹句表达情感的功能。
◆Step 2　Presentation Work on 3a 1.Present the sentences in 3a,guide students to observe and discuss,and summarize the guiding words and structure of exclamatory sentences. 2.Provide more examples and ask students to determine whether the exclamatory sentences are guided by “what” or “how.” 3.Explain the grammar rules of exclamatory sentences and how to rewrite a sentence into an exclamatory sentence. 教师通过观察学生的讨论和回答,了解他们对感叹句的理解程度,并根据学生的表现给予针对性指导,确保他们能够正确区分和使用what和how引导的感叹句。
设计意图:通过引导学生观察、讨论和总结感叹句的结构,结合例句判断和改写练习,帮助学生掌握感叹句的语法规则,并能够在口语和写作中正确使用感叹句表达强烈的情感。
◆Step 3　Practice 1.Work on 3b Students work independently on 3b,transforming declarative sentences into exclamatory sentences,with the teacher circulating to provide guidance.Groups then compare answers and discuss any sentences that are contentious,with the teacher addressing common issues collectively. 2.Work on 3c Complete 3c by selecting the appropriate exclamatory sentences based on context.Students work on this alone first and then exchange ideas within their groups,inviting group members to read aloud in character roles. 通过观察学生独立完成练习的情况,可了解其对感叹句结构的掌握程度;根据小组交流时的讨论,能反映出学生对知识点的疑惑点和争议点;分角色朗读则能检验学生对感叹句在语境中运用的熟练度,教师据此给予针对性反馈与指导。
设计意图:学生先独立完成练习,强化对感叹句知识的运用,培养自主思考能力;小组核对答案和讨论,促进学生之间的交流与合作,加深对知识的理解;分角色朗读,帮助学生更好地体会感叹句在实际语境中的情感表达,提升口语表达能力。
板书设计 Unit 5　What a Delicious Meal! 第3课时　Grammar Focus(3a-3c) 陈述句转换成感叹句的方法 四步搞定感叹句 一断:在谓语动词后断开　　　　　　　　　　　It is/a successful mission. They are/hard-working. 二换:斜线前后调换位置 a successful mission/it is. hard-working/they are. 三加:斜线前只要有名词,句首加what What a successful mission it is! 斜线前如果是形容词/副词,句首加how How hard-working they are! 四变:改变大小写,句末用感叹号,同时去掉原句中的一些像very/quite之类的修饰词
课堂评价
作业布置
必做: Create 4 exclamatory sentences—2 with what (one for countable noun singular,one for plural/uncountable nouns)and 2 with how—describing school life,hobbies,or family. 选做: Write a short passage (at least 80 words)describing a sports meeting,using exclamatory sentences.
教学反思
　　本节课通过视频导入和例句分析,成功激发了学生对感叹句的兴趣,并帮助他们初步掌握了感叹句的基本结构和用法。学生在观察、讨论和总结过程中表现积极,能够较好地理解what和how引导的感叹句的区别。然而,在独立练习和小组讨论中,部分学生对感叹句的改写和应用仍存在一定的困难,尤其是在区分what和how的使用场景时容易混淆。今后教学中,可以增加更多的例句和情境练习,帮助学生更好地内化语法规则。
