《Unit3 The Earth》廣東省蘭燕玲
共1學時
1教學目標
To enable students to talk about the environmental problems in Shenzhen and the ways to protect our city
To let students know how to make an outlining and write accordingly
To cultivate students' awareness of environmental protection
2學情分析
對于保護環境這一題材，非常貼近學生的實際生活。生活中環境污染的事例隨處可見，學生對于生活中人們如何破壞環境以及如何有針對性地減少環境破壞和污染有話可說，這將有利于學生真情實感的表達和學習活動的開展。
在語言知識方面，學生通過語法學習能較為熟練地使用There be句型來描述我們身邊的環境問題，并且用情態動詞must和mustn’t等討論為了保護家園，我們應該做什么和不應該做什么。
在學習能力方面，初一年級學生在小學英語的基礎上，已具備一定的書面表達能力。但由于學生的語言基礎不扎實，寫作經驗和技巧的欠缺，限時寫作還是有一定的困難。
