Lesson 1 Reading
一、教學內容分析
本課時為閱讀課，聚焦兩篇百科全書條目文本Leonardo da Vinci和Dinosaurs。前者以客觀簡潔的語言介紹達 芬奇的多重身份（畫家、發明家、音樂家等）、代表作品《蒙娜麗莎》及發明成就（如飛行機器設計），突出其 “天才” 特質；后者從生物分類、生存年代、體型差異及食性等方面介紹恐龍，穿插 “掃描閱讀” 技巧指導，要求學生通過快速瀏覽定位關鍵信息。文本結構清晰，采用 “主題 + 事實細節” 模式，配套 mini-quiz、填空等練習，強化信息提取與細節理解能力。
二、語篇分析
【 What】 本單元語篇包含兒童百科全書中關于達·芬奇（Leonardo da Vinci）和恐龍（Dinosaurs）的兩篇詞條內容。達·芬奇部分介紹了其出生年份（1452 - 1519）、國籍、職業、天賦才能及著名畫作《蒙娜麗莎》（Mona Lisa）等；恐龍部分闡述了恐龍是史前動物，與鱷魚、蛇、蜥蜴有親緣關系，是當今鳥類的祖先，還提及恐龍首次出現時間（約 2.45 億年前）、存活時長（超過 1.8 億年）、滅絕時間（約 6600 萬年前）、體型大小差異、食性以及科學家對其滅絕原因的探索等信息 。同時，圍繞這些語篇設置了閱讀前的小測驗、信息預測，閱讀中的掃讀（scanning）、精讀任務，以及閱讀后的詞匯練習等內容 。 【Why】 從知識維度，借百科場景拓展學生對歷史文化名人、史前生物的認知，搭建跨學科知識框架；能力維度，依托掃讀找時間、精讀填信息等任務，強化信息提取、文本分析及詞匯運用技能，適配課標 “獲取、梳理信息” 要求；素養維度，以 “查閱百科” 為依托，培養學生利用工具書探究知識的習慣，滲透科學探究思維與文化理解，讓學生體會百科全書在知識學習中的工具價值。 【How】 結構上，采用百科詞條典型范式，達 芬奇部分按 “生平 - 天賦與成就 - 影響” 線性展開，恐龍部分遵循 “定義 - 特征 - 演化 / 滅絕” 邏輯，層次清晰易讀；語言上，運用簡潔科普表述，以一般過去時等基礎語法為主，詞匯兼顧常見詞（如 “painter”“inventor” ）與學科詞（如 “prehistoric”“fossil” ），還融入詞匯后綴（-ist /-ian ）語法知識，既契合初中生語言水平，又助力語言知識積累與語法能力提升。
三、學情分析
學生已具備基礎的英語閱讀能力，對百科全書的功能有初步認知，了解常見人物及動物話題的基本詞匯。能夠通過上下文推測詞義，對趣味性較強的歷史人物和史前生物話題興趣濃厚，具備一定的信息提取和歸納能力。可能對百科全書條目嚴謹、專業的語言風格感到陌生，在理解長難句時存在障礙；對 “掃描閱讀” 技巧的實際運用不夠熟練，難以快速定位關鍵數據。渴望通過系統學習提升閱讀策略，深入理解百科類文本的結構特點，同時希望將閱讀內容與實際生活建立聯系。
四、教學目標
通過本課時的學習，學生能夠： 通過閱讀兩篇百科條目，提取達 芬奇的職業、代表作品及恐龍的生存時間、體型等關鍵信息，完成表格填寫與細節判斷。 學習“掃描閱讀” 技巧，快速定位文本中的信息，并在閱讀中實際運用該技巧。 掌握名詞的后綴-ist, -ia。 了解百科全書與字典的差異。
五、教學重難點
【重點】 通過閱讀兩篇百科條目，提取達 芬奇的職業、代表作品及恐龍的生存時間、體型等關鍵信息，完成表格填寫與細節判斷。 學習“掃描閱讀” 技巧，快速定位文本中的信息，并在閱讀中實際運用該技巧。 【難點】 通過閱讀兩篇百科條目，提取達 芬奇的職業、代表作品及恐龍的生存時間、體型等關鍵信息，完成表格填寫與細節判斷。 學習“掃描閱讀” 技巧，快速定位文本中的信息，并在閱讀中實際運用該技巧。

(1) When do you need to find information in an encyclopaedia
(2) What is the difference between a dictionary and an encyclopaedia
Discuss
When we need reliable, in-depth background knowledge on a topic quickly.
A dictionary mainly explains word meanings, pronunciations, and usages. An encyclopaedia provides in-depth knowledge on various topics like science, history, etc.
We use a dictionary to understand words. We use an encyclopaedia to learn about broad subjects and gain comprehensive information.
Reflect and share:
What new knowledge did you learn today How can it help you
Know more about Leonardo da Vinci and dinosaurs.
Know what an encyclopaedia is.
Example:
In the future, I will use encyclopaedias to find accurate information for my homework.
Summary
Base: Finish Exercise 3 on P7.
Practice: Find information about a celebrity and organize the information using the mind map on P11.
Expand: Interview your family members about “the encyclopedic subject they most want to look up” and record the reasons.
