自行车挂着的音箱里传来《答案在风中飘》的歌声:“How many years must a mountain exist?Before it is washed to the see。How many years can some people exist?Before they‘re allowed to be free.How many times can a man turn his head?And pretend that he just doesn‘t see。The answer, my friend, is blowing in the wind”(一座山要伫立多少年,才能被冲刷入海?一个人要生存多少年,才能获得自由?一个人要转多少次头,才能假装什么都没看见?答案啊,我的朋友,它在风中飘。)
