月夜忆舍弟
                                                                                                 【唐】杜甫
                                                                                         戍鼓断人行^① ， 秋边一雁声。
                                                                                         露从今夜白，月是故乡明。
                                                                                         有弟皆分散，无家问生死。
                                                                                         寄书长不达，况乃未休兵。
     【注释】断人行：指宵禁，即鼓声响起后，晚上不允许百姓随意外出。
