Teaching Reflection　【教学反思】 In this period，the students should have many chances to use the words and structures to talk about the environmental protection. They will learn new things by listening and speaking.In listening and speaking activities, they should use the grammar rules clearly. Then they must write down what they have talked about. In this way, their learning will be remembered better. So we can give them some written work to do after they do the listening practice and make conversations. 学科网（北京）股份有限公司 $ Section A 第 3 课时（3a〜4c) 自主学习方案 1.学生自学生词，并记住单词拼读和拼写。 2.预习课本，找出重点短语和句式。 3.读记后完成作业。 课堂导学方案 Step1 情景导入 Have you heard of the shark fins soup?
