keendow's notebook entry: Sep 26, 2010 glad to know so much freign friends here,I wish we can become good study partner and make progress together!

First notebook entry: Introducing myself I am a Chinese university student whose major is western medicine,and I am getting ready for the entrance exam of post graduate during my internship,so I am very busy these days and also feels pretty substantial. The reason why I work hard on my English is simple,because English is one of the most important course which works as a necessary language tool for deep study from western books or go abroad of a medicine majored student. Lastly,I hope some appropreate frends who had the same great goals as me will be met here,and I also expect we can study and make progress together!
