The openness of the Internet makes all kinds of information received into the vision of an equal chance and web sites in order to improve the hit rate which causes the traffic of commercial purposes such as tabloidization tend to be more negative news spread. To strengthen the research of network language management strategy, it has very important theoretical significance and practical meaning analyzed. Our proposed methodology will help researchers to understand the approaches to use the pragrnatics of politeness.展开更多
