运用后缀 -y 和动词不定式 to do 谈论旅行计划、描述人或事物特征并分享经历与感受
授课教师
语篇研读
【What】
语法知识维度包含两类核心内容:一是后缀 -y 的用法,可接在名词、形容词或动词后构成形容词(如 sun→sunny)或名词(如 soldier→soldiery),核心功能为描述人或事物的特征;二是动词不定式 to do,形式为 “to + 动词原形”(否定式 “not+to + 动词原形”),可作主语、宾语、宾语补足语、目的状语等,通过旅行计划相关对话(如 “I plan to go to Mount Huangshan.”)展示应用场景。所有语法示例均紧扣 “奇妙之地(Amazing Places)” 主题,围绕旅行规划、地标描述等展开。
【Why】
知识习得层面,掌握后缀 -y 能拓展词汇构建能力,助力自主推导同类生词含义;熟练运用不定式 to do 可完善句式表达,满足计划陈述、目的说明等交际需求。语言应用层面,依托 “旅行” 主题语境,学生可运用 -y 形容词描述天气、物品等特征(如 “rainy day”“woody bowl”),用不定式 to do 表达旅行计划与目的(如 “want to visit the Leaning Tower of Pisa”),实现语法知识向交际能力的转化,同时激发对世界地标与旅行的兴趣。
【How】
对于后缀 -y,借助 Activity 1 图片与句子归纳构词规则及语义;通过 Activity 2 情景造句、Activity 3 语篇补全,从词到篇逐步强化应用。
对于不定式 to do,以 Activity 1 双人对话引出核心用法,Activity 2 用表格梳理不同句法功能的肯定式与否定式,Activity 3 通过书信补全、句型练习巩固应用,遵循 “感知 — 梳理 — 应用” 的认知路径。
学情分析
学生已具备基础词汇储备和简单句式运用能力,但对词缀构词法和非谓语动词的系统掌握不足。在后缀 -y 学习上,虽接触过少量相关词汇(如 sunny),但缺乏对其构词规则、适用词类及词性转化的系统认知,易出现拼写错误(如误写 “rainy” 为 “rainny”)或词性误用。对于不定式 to do,学生熟悉简单搭配(如 “want to do”),但对其多种句法功能(如目的状语、宾语补足语)区分不清,常出现结构错误(如 “expect sb. do sth.”)。在主题应用中,学生难以将两类语法知识融合,清晰表达旅行计划与感受,需通过情境化练习、专项辨析强化认知。
课标要求
·语言知识:能识别并归纳后缀 -y 的构词规则及语义功能,掌握其形容词转化核心用法;精准区分动词不定式 to do 的基本形式(肯定、否定)及主要句法功能(宾语、宾补、目的状语等),能规范运用相关句型。

设计意图
Step 1 后缀 -y 学习(Suffix -y)(15min)
Activity 1: Observe and Summarize
1. Show pictures and sentences in Activity 1 (e.g. “The traffic is heavy because it is rainy.”), guide students to circle words with suffix -y, discuss the word formation rules and meanings in groups.
2. Present a classification table, summarize the semantic functions (forming adjectives/nouns) and word formation rules (adding to nouns/adjectives/verbs).
Activity 2: Sentence Making Practice
1. Distribute word boxes (smoky, windy, salty, etc.), ask students to work in pairs to talk about pictures and make sentences.
2. Invite groups to show their sentences and explain the reasons for word choice.
Activity 3: Text Completion
1. Show the short text in Activity 3 about the Leaning Tower of Pisa, guide students to fill in the blanks with the correct form of given words.
2. Read the text aloud as a class to strengthen the application of suffix -y in discourse.
1. Circle words with suffix -y, discuss and summarize their meanings and word formation rules in groups, and record confusing points.
2. Work in pairs to make sentences with given words, check each other's answers and explain the reasons.
3. Complete the text independently, check and correct with deskmates after reading aloud.
Help students understand the semantic functions and word formation rules of suffix -y through progressive learning of “pictures — words — discourse”, and strengthen application ability.
效果评价:自评 + 互评。Check the correctness of sentence making and text completion, and evaluate the completeness and accuracy of suffix induction among groups.
Step 2 不定式 to do 学习(The infinitive to do)(22min)
Activity 1: Dialogue Observation
1. Present the pair dialogue in Activity 1 (e.g. “Where do you plan to spend your holiday?” “I'll go to the beach to spend my holiday with my grandparents.”), guide students to circle the “to do” structure and discuss its usages.

Activity 2: Table Carding
1. Distribute table templates, ask students to complete Activity 2: fill in the positive and negative forms and examples of the infinitive to do for different usages.
2. Organize a group competition: the group that completes accurately the fastest wins the “Grammar Star”.
Activity 3: Sentence Pattern Practice & Text Completion

教学反思
·本节课通过旅行计划情境导入和 “旅行计划讨论” 活动,将语法学习与主题表达深度结合,学生参与积极性高,基本掌握了后缀 -y 和动词不定式 to do 的核心用法。亮点在于旅行主题相关练习设计,有效促进了语法知识的融合应用,同时激发了学生对旅行的兴趣。
·但存在不足:部分学生仍混淆后缀 -y 的构词规则,且在不定式 to do 的句法功能区分上不够熟练(如误用目的状语为宾语)。
·未来教学中,需增加 “后缀 -y 构词专项训练”(如词汇变形竞赛),设计 “不定式句法功能辨析题” 强化用法区分;通过更多真实旅行对话实例,让学生在具体语境中灵活运用两类语法知识,提升语言表达的准确性与自然度。
