Explain the intention of some teaching links (this refers to the preset teaching intention before class) or summarize the teaching effect (this refers to the feedback on the classroom situation when the follow-up introductory lecture is given to the class that has been attended). For example, in this link, students combine vivid pictures with boring sentences in the text, which brings students into the scene well, and the classroom atmosphere suddenly becomes active, which has achieved the expected results. )
