亲爱的小朋友:在杭州四中,有一群14岁的哥哥姐姐正在集体过生日,他们将告别儿童少年,步入青年。此刻他们的心中涌动着三个字:责任感。很小的时候,老师、爸爸妈妈就告诉我们:每个人都要有责任感,它是我们人类推动社会进步的驱动力。究竟应先对自己负责还是先对社会负责?听一听哥哥姐姐怎么说吧! Dear Children: In Hangzhou No. 4, a group of 14-year-old brother and sister are celebrating their birthday together. They will bid farewell to children and adolescents and enter the youth. Now they surged three words: a sense of responsibility. At a very young age, teachers, parents and mums told us that everyone must have a sense of responsibility and it is the driving force for our humankind to promote social progress. Should you be responsible for yourself or the society first? Listen to your brother and sister, how to say it!
