Unit 8 Detective stories Grammar 教学设计 I. Teaching Objectives 1. Knowledge Objectives Students will master defining relative clauses, understanding the use of relative pronouns who, which, that to describe people or things. Students will learn to identify and construct defining relative clauses in sentences related to detective stories. 2. Ability Objectives Improve sentence - building skills by creating and analyzing defining relative clauses about crime cases and detective elements. Enhance writing skills by applying relative clauses to describe suspects, clues, and crime details. 3. Affective Objectives Strengthen logical expression in English through proper use of relative clauses. Connect grammar learning to detective story themes, making language use relevant and engaging. II. Language Knowledge 1. Key Words & Phrases Relative pronouns: who, which, that Detective - related expressions: suspect, clue, crime, murderer, witness 2. Key Sentences “A detective is someone who looks for clues to something important.” “We are asking anyone who saw anything unusual near Corn Street last night to contact us.” 3. Key and Challenging Points Key Points: Correct use of who (for people), which (for things), that (for people/things) in defining relative clauses; recognizing essential information in such clauses. Challenging Points: Distinguishing between defining and non - defining relative clauses (implicitly, by understanding essential info); using relative clauses fluently in writing. III. Teaching Procedures (Total Duration: 45 Minutes) Step 1 Lead - in (6 Minutes) Show a picture of a detective with clues and ask: “How can we describe the detective and clues more vividly? Can we use sentences to give more info?” Introduce: “Today, we’ll learn grammar to add details—defining relative clauses—perfect for detective stories!” Step 2 Defining Relative Clauses Explanation (12 Minutes) Structure & Pronouns (6 Minutes) Explain: Defining relative clauses add essential info to nouns, using who (people), which (things), that (people/things). E.g., “The suspect who was seen running is important.” Highlight: Can’t remove the clause without changing meaning. Detective - Themed Practice (6 Minutes) Use Part A examples: Identify relative clauses in sentences about the murder case, discussing pronouns and essential info. Step 3 Practice with Relative Pronouns (15 Minutes) Part B1 & B2 (8 Minutes) Students complete B1 (detective story sentences with who, which, that) and B2 (crime - related relative clauses). Guide: Match pronouns to people/things (e.g., “writers who...”, “stories which...”). Error Analysis (7 Minutes) Discuss answers, analyzing common errors (e.g., wrong pronoun choice). Step 4 Integration & Application (8 Minutes) Create Your Own Clauses (5 Minutes) Students write 3 sentences about a detective case, using defining relative clauses (e.g., “The clue which was found is important.”). Peer Sharing (3 Minutes) Pairs share sentences, checking for correct structure and relevance to detective themes. Step 5 Summary & Homework (4 Minutes) Summary (2 Minutes): Recap relative pronouns, defining relative clauses, and their use in detective stories. Homework (2 Minutes): Write a short paragraph about a detective’s investigation, using at least 3 defining relative clauses. IV. Assessment of Teaching Effectiveness Check B1, B2 for accurate relative clause construction. Evaluate student - created sentences for proper pronoun use and essential info inclusion. Assess homework paragraphs for integrated relative clause use. V. Design Purpose Lead - in: Connect to detective themes to introduce grammar’s role in adding details. Explanation: Clear structure breakdown with detective examples. Practice: Apply to crime - related tasks for relevance. Homework: Reinforce with personal detective - themed writing. VI. Blackboard Design Unit 8 Grammar — Defining Relative Clauses Relative Pronouns: - who → people (e.g., *“suspect who...”*) - which → things (e.g., *“clue which...”*) - that → people/things (e.g., *“info that...”*) Key: Clause gives essential info—can’t remove! Homework: Write detective paragraph with 3 clauses! VII. Teaching Reflection Strengths: Detective theme makes grammar practice engaging. Weaknesses: Some students may confuse pronoun usage in complex sentences. Improvements: Add a “Clause Sort” activity: Sort sentences by pronoun to reinforce correct usage. 学科网（北京）股份有限公司 $$
