Unit 1 Friendship
Lesson 4 Grammar
一、教學內容分析
本課時重點為“形容詞比較級和最高級”，核心內容包括：①規則變化（如 “tall-taller-tallest”“helpful-more helpful-most helpful”）；②不規則變化（如 “good-better-best”）；③運用場景（對比朋友身高、性格等）。通過 “朋友特點對比” 情境中的觀察、歸納、練習，讓學生理解語法規則并能在真實交流中運用。
二、學情分析
八年級學生已掌握 “tall, kind, helpful” 等基礎形容詞，對 “比較” 有生活認知（如 “我的朋友比我高”），但存在以下難點：①單音節與多音節詞變化規則混淆（如誤寫 “helpfuler”）；②不規則變化（如 good→better）記憶不牢固；③“the + 最高級 + 范圍” 結構易漏用 “the” 或范圍狀語。適合通過 “朋友對比” 的熟悉情境，在運用中突破難點。
三、教學目標
通過本課時的學習，學生能夠： 通過 “例句觀察與小組討論” 活動，學生能歸納形容詞比較級和最高級的規則變化（單音節 / 多音節）及3組核心不規則變化（good→better→best；bad→worse→worst；many→more→most）； 通過“朋友特點對比練習”活動，學生能正確使用 “比較級 + than”“the + 最高級 + in/of” 結構完成 5 組以上朋友外貌、性格的對比表達； 通過“小組分享”活動，學生能結合自身經歷用所學語法談論朋友，感受語法在真實交流中的作用。
四、教學重難點
【重點】掌握形容詞比較級和最高級的構成規則；正確使用“比較級 + than”“the + 最高級 + 范圍”結構描述朋友。 【難點】多音節形容詞（如 outgoing）的比較級（more outgoing）和最高級（most outgoing）使用；不規則變化的靈活運用。
五、教學活動設計
環節一：導入（5mins) 教師展示視頻，自然引出 “比較級最高級” 主題。
教學活動 活動層次 效果評價
Students watch a video and answer: What’s song about 學習理解 — 感知與注意 觀察學生能否準確說出視頻主題，判斷其對視頻內容的理解和抓取關鍵信息的能力。
環節設計意圖：通過視頻直觀呈現與“比較”相關的場景（如不同發明的功能對比），激發學生興趣，自然引出 “比較級、最高級” 主題，為后續學習做好鋪墊。
環節二：規則探究（15mins） 教師出示朋友主題的例句，引導學生結對歸納單音節 / 多音節詞變化規則并填表；通過對比發現不規則變化，強化記憶。
教學活動 活動層次 效果評價
Read and observe Read the sentences and pay attention to the use of comparative and superlative adjectives. Read and conclude Conclude what comparative and superlative adjectives are used for. Summarize the rules of comparatives and superlatives. 學習理解 — 概括與整合 學生能準確填寫規則表格，說出 “short adjectives + er/est; long adjectives + more/most”，掌握 3 組不規則變化。
環節設計意圖:通過 “觀察 — 討論 — 歸納” 的活動，讓學生自主構建規則，避免機械記憶，培養語法思維。
環節三：情境運用（15mins） 教師先設計控制性練習鞏固規則，再讓學生結合 “朋友身高、性格” 等提示結對對話，在交流中運用語法。
教學活動 活動層次 效果評價
Complete the table with the correct comparative and superlative adjectives. Daniel has made some notes about his plete his notes. Describe your friends, including their looks and what they are good at, using comparative and superlative adjectives. 應用實踐 — 描述與闡釋 學生能正確完成 80% 控制性練習，對話中能使用 “比較級 + than”“最高級 + 范圍” 結構，話題圍繞朋友。
環節設計意圖:通過從“機械練習”到“真實交流”，讓語法運用回歸“描述朋友”的主題，體現 “用中學”的英語學習活動觀。
環節四：總結與練習（5mins） 教師用思維導圖總結規則（附朋友主題例句）；通過 “詞匯 — 圖片匹配” 游戲，強化語法與意義的關聯。
教學活動 活動層次 效果評價
Grammar consolidation exercise: The teacher presents exercise related to the this class. Summarize the key grammar tips. 學習理解 — 鞏固與應用 學生能快速回應游戲指令，準確關聯語法形式與朋友行為場景。
環節設計意圖:通過用思維導圖梳理規則，搭配互動游戲，讓總結環節生動高效，強化 “語法服務意義” 的認知。
作業與拓展 Basic：Copy the rules and 5 example sentences (e.g., “My friend is more outgoing than me”). Complete 3 sentences about your friend’s looks with comparatives or superlatives. Practice：Interview your deskmate: “Who is taller, you or your best friend Who is the most friendly in your group ” Write down 2 answers with correct forms. Expand：Make a “Friend Card”with a photo of your friend. Write 2 comparative sentences and 1 superlative sentence to describe him/her (e.g., “Lily runs faster than me. She is the most creative friend in my life”)
