with this problem.Having lived in China for about five years,I am totally used to daily life here.That shouldnt be something to complain about,right?Adapting to a different society and culture is something to be satisfied with,is it not?Usually it would be.However,it makes writing a column about my impressions of China a lot more difficult.,In the West,student life is a combination of study and socializing with a heavy emphasis placed on the socializing part!I was genuinely impressed by the dedication and motivation of Chinese students.When I was a student I would rarely give up my spare time to any activity connected with study.Unless exams were approaching,my weekends were devoted to having fun or perhaps a part-time job.My Chinese students,on the other hand,seemed to spend their entire waking hours studying.I understand that competition in Chinese universities is extremely intense.Nonetheless,their energy and drive put me to shame.,Ive heard a saying that went,17,It may be true that rote learning is over-emphasized in Chinese education.Nonetheless,I found that this does not reflect the natural character of Chinese students.Given the appropriate classroom atmosphere and
