参考词汇：改革renovation Last Wednesday I gave a lecture about China’s culture and history to the 7th students from 9-11:30 in the morning. This is the first time I gave a lesson, so I felt very nervous and great pressure. I presented for one and a half hours, introducing from the dynasties in ancient times to the revolutionary in recent times, but I spent a lot more time on present China, the renovation, the open policy and the economic development. In the following hour we exchanged ideas and had a good discussion, but I was sorry to find that they knew little about China and raised a lot of strange questions. I think we need more cultural exchange of this kind, because we can get more practice and the foreign students can understand more about China.
