《Unit3 The Earth》广东省兰燕玲
共1学时
1教学目标
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学情分析
对于保护环境这一题材，非常贴近学生的实际生活。生活中环境污染的事例随处可见，学生对于生活中人们如何破坏环境以及如何有针对性地减少环境破坏和污染有话可说，这将有利于学生真情实感的表达和学习活动的开展。
在语言知识方面，学生通过语法学习能较为熟练地使用There be句型来描述我们身边的环境问题，并且用情态动词must和mustn’t等讨论为了保护家园，我们应该做什么和不应该做什么。
在学习能力方面，初一年级学生在小学英语的基础上，已具备一定的书面表达能力。但由于学生的语言基础不扎实，写作经验和技巧的欠缺，限时写作还是有一定的困难。
