Ask students to use the Internet to search for more information about the grammar learned in this unit. Cultural Corner introduces the history and use of abacus. After the article, ask the students to answer the questions and consolidate the knowledge they have learned. At the end of the lesson, the teacher will summarize, guide the students to refine and summarize the fragmentary knowledge, establish the connection between the new knowledge and the existing knowledge, and form a systematic knowledge system in the students' minds to facilitate their memory. Guiding students to learn should be extended from class to extracurricular. On the basis of understanding the content of the text, consolidate the new knowledge and carry out "one against three" simultaneously. 教师在课堂上复习提问、讲解新课，安排学生自行消化和练习，都是为了当堂巩固知识和为以后复习、作业和运用打好基础,有利于培养学生的目标意识，根据自身情况及时解难纠错。总结有承上启下的作用，还能调动学生的积极性，使学生重温所学的知识，进一步明确学习目标。
