Unit 5 Languages Around the World Discovering Useful Structures 教案-2026-2027学年高中英语人教版必修第一册

该高中英语教案聚焦定语从句中关系副词（when, where, why）及“介词+which”结构，以“书写系统的历史与多样性”为主题。课堂导入通过课本句子填空活动，引导学生讨论并猜测缺失的关系词，观察时间、地点、原因相关词汇，搭建从已知关系代词到未知关系副词的学习支架，梳理语法知识脉络。 本资料亮点在于采用归纳发现法，通过小组分析句子卡片（圈划先行词、分析从句成分）自主归纳语法规则，培养学生思维品质中的分析与归纳能力。结合主题设计“我的语言记忆”写作任务，要求运用三种关系副词及“介词+which”结构，在语言输出中提升语言能力，同时融入汉字、甲骨文等文化元素，增强文化意识。提供差异化支持（如弱生句子框架、优生拓展非限制性定语从句），助力教师实施分层教学，有效提升学生语法运用与文化理解能力。

人教版英语必修一unit 5定语从句教案 I.Basic Lesson Information Subject: Senior High English Grammar Topic: Relative adverbs & the structure“preposition + which” Theme: History & diversity of writing systems Teaching Materials: Textbook sentences, sentence cards, writing worksheets II.Learning Objectives Identify relative adverbs when, where, why in restrictive attributive clauses and analyze their grammatical functions. Tell relative adverbs apart from relative pronouns by judging the antecedent’s role in subordinate clauses. Rewrite sentences with the equivalent “preposition + which/whom” structure and choose proper prepositions correctly. Write a short paragraph about language history with at least three attributive clauses using relative adverbs. III.Teaching Ideas Grammar is a practical language tool instead of rigid rules. This lesson uses an inductive discovery method. Students summarize grammar rules from context sentences about language evolution, then apply rules to personal writing. IV.Teaching Procedures Stage 1: Lead-in (6 mins) Activity: Fill in blanks with relative words Show four sentences from the textbook with blanks for pair discussion: 1.It was a time ______ people lived in separated regions. 2.Qin unified China into a country ______ the writing system developed in one direction. 3.There are many reasons ______ people learn foreign languages. 4.Ancient people carved symbols on animal bones and shells ______ we call oracle bones. Students guess missing words and explain their reasons. Teacher guides students to notice words for time, place and reason. Stage 2: Discover Grammar Rules (10 mins) Group work: Analyze sentence cards following three steps. 1.Circle the antecedent (the modified noun). 2.Underline the attributive clause. 3.Check if the antecedent acts as subject, object or adverbial in the clause. Group sharing & key rules concluded together: Rule 1: Use when / where / why if the antecedent serves as time, place or reason adverbial in the clause. Rule 2: Use relative pronouns (which, that, who) if the antecedent acts as subject or object. Rule 3: Every relative adverb can be replaced by “preposition + which”. The preposition matches the collocation of the antecedent. Stage 3: Grammar Explanation & Key Reminders (8 mins) Equivalent Structure Chart Relative Adverb Equal Structure Preposition Rule when prep. + which Matches time nouns: in the year, on the day, at the moment where prep. + which Matches place nouns: in the country, at the station why for which Fixed collocation for the word “reason” Common Mistake Warnings 1.Do not judge by the noun’s meaning; judge by its grammatical role in the clause. I miss the days when we worked together. (days = time adverbial → when) I miss the days which we spent together. (days = object of spent → which) 2.Do not repeat prepositions after where. Wrong: the factory where he works in Right: the factory where he works / the factory in which he works 3.Do not use “because” after “the reason why”. Wrong: The reason why he left was because he was busy. Right: The reason why he left was that he was busy. Stage 4: Practice & Error Correction (10 mins) Task 1 Individual Gap-filling Fill in blanks with when, where, why, which, that, who or “prep.+which”. Mark the antecedent of each sentence. 1.Kanji ______ came from Japan originates from ancient Chinese characters. 2.1953 was the year ______ Xinhua Zidian was published. 3.Oracle bones ______ ancient symbols were carved are important cultural relics. 4.There are many reasons ______ English spreads worldwide. 5.Sign language helps people ______ have hearing problems. Task 2 Pair Error Correction Fix grammar mistakes and explain errors in pairs. 1.This is the library where I read books in. 2.The reason why she cried was because she lost her textbook. 3.I still remember the summer when I enjoyed last year. Stage 5: Output Writing (9 mins) Writing Task: My Language Memory (80–100 words) Write about a special time, place or reason connected with language learning. Requirements: 1.One clause with when / prep.+which 2.One clause with where / prep.+which 3.One clause with why / for which Writing prompts: Time: The moment ______ I fell in love with words was… Place: There is a small study ______ I practice handwriting… Reason: The main reason ______ I keep learning English is… Peer review checklist: 1.The antecedent is clear. 2.Relative words match the antecedent’s function. 3.“Preposition + which” structures are correct. Stage 6: Summary & Homework (2 mins) Exit Ticket: Write one sentence with a relative adverb to show your biggest takeaway today. Homework: Read the UN multilingual passage handed out. Underline all attributive clauses, label the antecedent, relative word and its “preposition + which” alternative. V. Assessment Methods 1.Formative recognition: Group sentence analysis. 2.Grammar analysis: Individual gap-filling exercise. 3.Error evaluation: Pair error correction activity. 4.Language production: Paragraph writing & peer review. 5.Self-reflection: Exit ticket sentence. VI. Differentiated Teaching For weak students: Provide sentence frames and preposition matching cards for writing. For advanced students: Add non-restrictive attributive clauses with relative adverbs and explain punctuation rules. Cultural expansion: Encourage writing about Chinese writing systems or local language traditions. VII. Blackboard Layout Unit 5 Relative Adverbs: when / where / why 1.Judgment Rule Antecedent (time/place/reason) → Subject / Object → which / that / who → Adverbial → when / where / why 2.Preposition Replacement when = in/on/at + which where = in/at/on + which why = for + which 3.Typical Mistakes ❌ where ... in ❌ the reason why ... because ❌ when used for object antecedents 答案 Stage 1 Lead-in 填空答案 when where why which/that Stage 4 Task1 Individual Gap-filling which/that when / in which where / on which why / for which who/that Stage 4 Task 2 Pair Error Correction Wrong: This is the library where I read books in. Right: This is the library where I read books. / This is the library in which I read books. Mistake: Where equals "preposition + which", so don’t repeat the preposition "in". Wrong: The reason why she cried was because she lost her textbook. Right: The reason why she cried was that she lost her textbook. Mistake: "The reason why…" cannot be followed by "because", use "that‑clause" as predicative clause. Wrong: I still remember the summer when I enjoyed last year. Right: I still remember the summer which/that I enjoyed last year. Mistake: The antecedent "the summer" acts as the object of "enjoyed", not time adverbial, so we cannot use when. Stage 5 Output Writing 参考范文 (My Language Memory 92 words) The moment when I first touched ancient Chinese characters was unforgettable. There is a small study where I practice Chinese handwriting every weekend. The main reason why I keep learning languages is that they carry rich history and culture. I often copy characters on paper, which helps me understand how our writing system developed. I believe language is a treasure that connects us to the past. Stage 6 Exit Ticket 参考例句 I will never forget the day when I learnt the history of Chinese writing system. This is the classroom where we study grammar of attributive clauses. 学科网（北京）股份有限公司 $
