一. 教材內容分析
本單元的話題是“保護環境”。3a-3c是閱讀任務。本部分閱讀文章為一篇倡議書,介紹了人類捕捉鯊魚獲取魚翅,破壞生態平衡的情況。文章內容緊扣本單元話題,呼吁人們保護鯊魚,引導學生關愛、保護野生動物,保護環境,滲透了對學生的情感教育。
本節課是人教版初中英語九年級Unit 13 Section A (3a-3c).在前一節課有關環境污染的基礎上,談論保護野生動物,維護生態平衡,保護大自然這一話題。3a閱讀文章為一篇倡議書,介紹了人類捕捉鯊魚獲取魚翅,破壞生態平衡的情況,同時介紹了環境保護組織所做的努力,呼吁保護鯊魚。文章內容緊扣本單元話題,注意引導學生關愛、保護野生動物,保護環境,滲透了對學生的情感教育,可以幫助學生提升綜合人文素養,幫助他們形成良好品格和正確的價值觀。
二.學 情 分 析
本單元的話題學生較為熟悉,為環保問題。但是對于本課有關鯊魚的了解較少,為本課的學習增加了閱讀障礙。因此,我在備課時精心選擇相關背景知識,幫助學生順利理解文本所傳達的信息。例如在第二段給學生提供為什么漁民只割掉魚鰭而把鯊魚扔回海里,為什么說目前人類大肆捕捉鯊魚會對生態系統產生危害,以及魚翅的營養真相等等,幫助學生真正理解文本和作者想要表達的意圖。

Unit 13 Section A (3a-3c)
Save the sharks!
Shark fin soup be endangered against “finning”
Southern China a bowl\a whole cut off WildAid WWF Throw…black into die
教學反思:
通過閱讀文章,了解鯊魚種群面臨的危險及原因,理解拯救鯊
魚的緊迫性,了解環境保護組織所做的努力。學生學習了閱讀的相關技巧,提高了閱讀水平。并且學習了文章的架構“提出觀點-分析問題-解決問題”,并嘗試通過寫倡議書進行應用,提高了學生的寫作能力。
不足之處:
本節課鯊魚的習性和現狀離學生生活實際較遠,應該在課前提前指導學生進行相關背景的學習。比如給學生一些有關鯊魚的問題,讓他們上網或去圖書館查閱資料。另外,還可以課前讓學生了解有關Wild Aid和WWF的相關資料。
