Unit 3 To be a good learner
Word power
一、教学内容分析
本课时围绕名词后缀-er, -or, -ist的构词法展开,核心内容包括:通过动词(如teach, act, invent)和名词(如art, science, piano)加后缀构成表示“从事特定职业或活动的人”的名词(如teacher, actor, inventor, artist);结合具体语境(如职业介绍、人物描述、日常对话)呈现词汇运用场景;设计梯度练习(从词形转换到句子创作)帮助学生掌握构词规律。教学内容注重在真实语境中渗透构词逻辑,为学生拓展词汇量、提升语言运用能力奠定基础。
二、语篇分析
What:语篇由三部分构成——构词规则说明(明确-er, -or, -ist的基本用法)、人物身份描述(如“a great inventor and scientist”)、情境对话(讨论“people with multiple jobs”,运用目标词汇)。 Why:引导学生理解后缀构词的表意功能,掌握通过词形变化拓展词汇的方法,同时培养“关注职业多样性”的跨文化意识,提升语言学习的实用性。 How:采用“规则讲解—语境示例—实践运用”的递进结构,先以典型例子说明后缀用法,再通过人物描述和对话提供真实语言情境,最后通过练习实现知识内化。
三、学情分析
八年级学生已掌握部分含后缀的词汇(如worker, doctor),对“词形变化表身份”有模糊认知,但对-er, -or, -ist的适用范围(如-er多用于普通动词,-or多用于以“t”结尾的动词,-ist多用于与学科、艺术相关的名词)缺乏系统梳理,且对不规则变化(如piano→pianist, biology→biologist)易混淆。学生乐于参与互动游戏和合作任务,需借助丰富语境和多样化练习突破难点。
四、教学目标
通过本课时的学习,学生能够: 1.通过规则梳理与语境感知,理解后缀-er, -or, -ist构成表示人的名词的基本规律及适用场景。 2.通过多样化练习活动,能运用所学后缀完成词形转换,并在句子和对话中正确使用目标词汇。 3.通过合作探究与语言实践,培养构词思维和跨文化交际意识,提升自主拓展词汇的能力。
五、教学重难点
【重点】掌握-er, -or, -ist的构词规则(动词/名词+后缀→表人的名词),熟练转换常见词汇。 【难点】辨析后缀的适用差异,掌握不规则变化,并在语境中正确使用这些单词。
六、教学活动设计
环节一:导入(3 mins) 展示熟悉人物图片引导学生说出职业并讨论词汇共同点,以激活已知词汇并初步感知后缀特征。

Teacher displays pictures of familiar people (e.g.,a teacher, a singer, a doctor, a author, a artist, a scientist) and asks students to name their jobs. Students look at the pictures, say the job names, and discuss:“What do these words have in common ”(Guide to find suffixes-er,-or,-ist). 学习理解之感知与注意 学生能准确说出图片中人物的职业名称,并对“后缀表身份”产生初步联想和探究欲。
环节设计意图:以直观图片为语境,自然衔接学生已有知识,激发对构词规律的兴趣,符合新课标“从学生经验出发”的理念。
环节二:规则呈现与辨析Rule Analysis(10mins) 呈现词根与目标词讲解后缀规则,学生分组分类词汇,同时强调不规则变化,以呈现并辨析后缀规则及适用场景。
教学活动 活动层次 效果评价
Teacher presents a chart with roots and target words and explains:“-er, -or, -ist are added to verbs or nouns to mean‘a person who does...’”. Teacher highlights rules:“-er is often used with common verbs; -or with verbs like invent, direct; -ist with nouns about arts or sciences”. Students work in groups to sort given words (e.g., visit→visitor, paint→painter, biology→biologist) into three columns by suffix, and then share reasons. Teacher points out irregular changes: “Notice: dance→ dancer (drop ‘e’ before -er); photograph→ photographer (add ‘er’ after ‘graph’)”, and students repeat with examples. 学习理解之获取与梳理 学生能准确分类词汇,清晰说明不同后缀的适用特点,并能识别不规则变化的词形。
环节设计意图:通过“讲解—分类—辨析”的活动链,引导学生主动建构知识,在合作中突破“后缀差异”难点,体现“学思结合”的活动观。
环节三::基础练习Basic exercises——词形转换与匹配(7mins) 学生完成词形转换表和词汇与释义匹配任务,教师讲解难点,以巩固词形转换规则。
教学活动 活动层次 效果评价
Task 1:Students complete a word transformation table individually, and then check answers with a partner. Task 2:Teacher gives a list of definitions (e.g.,“A person who plays the piano”) and asks students to match them with the correct words in pairs. Teacher reviews difficult items and explains the logic behind the changes. 应用实践之内化与运用 学生能独立完成转换练习,匹配任务中能快速关联词汇与含义,对易错词有明确认知。
环节设计意图:通过梯度基础练习,帮助学生夯实知识,为后续语境运用奠定基础,体现“循序渐进”的教学原则。
环节四:语境运用Contextual application——对话补全与角色扮演(10 mins) 展示关于梦想职业的对话,学生补全对话并结合个人想法角色扮演,以在语境中运用目标词汇。
教学活动 活动层次 效果评价
1.Teacher presents a dialogue between two students talking about their dream jobs:“I want to be a ______ (science)because I love doing experiments. What about you ”“I want to be a______(sing)and a______(write)!” 2.Students fill in the blanks with correct words,then practice the dialogue in pairs,adding their own dream jobs (e.g.,“I want to be a painter and a dancer”). 3.Teacher invites 2-3 pairs to perform their dialogues, and the class gives feedback on word usage and fluency. 应用实践之内化与运用 学生能准确补全对话中的词汇,角色扮演时语言流畅,能灵活运用所学词汇描述个人想法。
环节设计意图:将词汇运用融入贴近学生生活的“梦想职业”话题,让语言学习与真实表达结合,践行“用英语做事情”的新课标理念。
环节五:综合练习Comprehensive exercise——句子创作与图片描述(8 mins) 学生创作关于家人的句子、小组描述图片人物活动,以综合运用所学词汇提升表达能力。
教学活动 活动层次 效果评价
Task 1:Students write 3 sentences about their family members’ jobs or hobbies using target words(e.g.,“My dad is a great gardener—he loves planting flowers”). Task 2:Teacher shows pictures of people doing different activities (e.g.,a person painting,a person inventing) and asks Students to describe them in groups:“He is a______; he likes to______”. Groups share their descriptions,and Teacher comments on word choice and sentence structure. 应用实践之内化与运用 学生写出的句子语法正确、词汇运用恰当,图片描述能准确关联人物行为与职业名称,体现对构词法的灵活掌握。
环节设计意图:通过“写—说—合作”的多元任务,全面检验学生的语言运用能力,培养“思维品质”和“合作意识”。
环节六:总结(2 mins) 教师带领学生回顾所学后缀及其构词作用,总结构词法价值,以梳理核心知识并激发持续学习动力。
教学活动 活动层次 效果评价
1.Teacher leads a review:“What suffixes have we learned How do they help us build new words ”Students answer and list examples. 2.Teacher concludes:“These suffixes are like‘word builders’—they help us know more words.Keep practicing,and you’ll be a good word learner!” 学习理解之概括与整合 学生能清晰回顾后缀规则及典型例子,对“构词法拓展词汇”的意义有明确认识。
环节设计意图:通过师生互动回顾本课核心的后缀构词规则及典型示例,帮助学生系统梳理所学知识,强化对“-er, -or, -ist”构词规律的整体认知,巩固教学重难点。
作业与拓展 Base: Add more words to form a “suffix vocabulary list” (at least 20 words, such as driver, editor, chemist). Practice: Interview three classmates about their interests and describe their potential careers in five sentences. Expand: Research other suffixes that mean people in English, and add them to your notes.
