TopicTalkPeriod1Unit3Conservation文本分析WhatHowWhy作為本單元的單元導入，為本單元的內(nèi)容做了充分的主題和詞匯的鋪墊。學生通過學習大自然受人類活動的影響、大自然被破壞的方式及人類保護自然的積極行動相關表達，感知保護大自然的重要性。本課屬于“人與自然”主題，倡導學生改變生活方式、激發(fā)學生保護自然的意識。本課以兩段聽力對話為主要內(nèi)容：第一段對話圍繞地球面臨最大的環(huán)境問題展開，說話者列舉了破壞環(huán)境的因素并倡議使用清潔能源和回收利用廢棄物；第二段對話以犀牛被非法獵取為例激發(fā)學生保護動物的意識。第一段對話描述人類使用不可循環(huán)和不可回收資源對自然環(huán)境造成了巨大威脅，由humanactivities,thingstobeprotected,wayswedestroynature和positiveactions幾部分構成。第二段對話提出了保護瀕危動物的倡議，常用表達包括workonprotecting…,beillegallyhuntedfor…,makeeveryoneknow…,anincrediblyurgentmatter等。1.Obtainthedetailedinformationabouttheconservationfromdifferentaspects.（語言能力，學習能力）TeachingObjectives學習理解應用實踐遷移創(chuàng)新2.
