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.
