This paper uses the data from one semester to state how to carry out the program and the good results. At the same time disadvantages are also the points that should be taken into consideration. From the teaching and learning practice, students have benefited from the online videos, complementary materials and discussions;they need to be guided as well, especially the guidance offline to make up. Furthermore, the balance of time online and offline is a great challenge.展开更多

In the performances of the opening ceremony, how is the traditional Chinese culture blended with the modern civilization through the programming? What kinds of cultural elements should be selected so as to present the spirit and the essence of the Chinese culture to the world? This paper, through grasping the overall form and scrutinizing meticulously the typical elements in the performances,aims to explore the cultural mechanism included in the large-scale modern cultural activities on the one hand. On the other, it intends to reveal that China tries to demonstrate the achievements of its modernization drive through successfully hosting the Games which is taken as a vital part of modern project. More importantly, China which is in the period of social transformation uses the opening ceremony to demonstrate its cultural awareness, cultural strategies and cultural consultation in a globalized world.展开更多
