If you Google“the 71st Anniversary of the Nanjing Massacre”(in Chinese)on the Internet，you will be impressed by the video show of a girl’s special commemoration．After watching the video．I Was wondering where college students were．Taking into consideration their indifference to other historic events such as the May 4 Movement，we can conclude that college students lack the due social responsibilities．
    However，we should not simply criticize their indifference，and analysis should be made to reckon with underlying reasons．Firstly，college students are imposed excessive pressure by the job market．They have to pay more attention to their studies．Secondly，many students believe that the history has already been borne in mind，and it is unnecessary to commemorate historic anniversaries each year．For them，it is better to internalize the humiliated history and work hard than to hold ceremonies without concrete contents．
    To my way of thinking，college students should not keep silent on those occasions．It is our responsibilities to voice Our aspirations and let the society know that we have not forgotten the history．
