Teaching Reflection 【教学反思】
In this period，we should practice making inferences with must，might，could and can't in reading and the situation.Students must finish every activity by their own reading.The teacher should let the students feel how to use these modal verbs instead of teaching and explaining.We always get the students to learn grammar by summing up the sentences they have learned.Students can practice grammar by using.After they know how to use these modal verbs to make inferences，the students should practice in different activities.And we give them some written work after speaking and reading.
