Editors’ Note: The New Year approaches as we greet the first anniversary of China International Studies. Availing ourselves of this opportunity, we sincerely wish our readers a happy and prosperous New Year! China International Studies began its publication last December. Since its inception, various think-tanks and institutions of higher learning both at home and abroad as well as Chinese embassies in foreign countries and foreign embassies in Beijing have offered it great support. Many readers wrote to us giving their encouragement on this new-born publication. We are carrying some of the messages in this issue to express our deep appreciation. Articles in this issue are mainly on the Middle East situation, the Iran nuclear issue, China-EU relations, China-India relations and China’s peaceful diplomacy. We are also publishing a paper by a foreign scholar for the first time. 展开更多

The current paper presents the linguistic analysis of a Chinese greeting “nihao” in both literature and reality, and compares the practical use of “nihao” by both native and non-native Chinese speakers, which leads to a discussion of some existing problems observed in foreign language teaching and learning. The problems include overuse and overgeneralization of certain words and expressions, and lack of use of some others. These problems are caused by the deficient exposure to authentic (non-)linguistic setting. The study may provide a further understanding of the communicative method of teaching and learning a different language. 展开更多
