Teaching Reflection 【教学反思】
In this period，the students should try to expand the topic and practice more in listening and speaking.They will improve their capacity of language organization to make inferences by using “could/might be doing”．Oral output is important.So we give them chance to say out more.When they are practicing the conversation，get them to make their own imagination and practice with their own words.
