桃花庵歌

(明)唐寅

桃花坞里桃花庵,桃花庵下桃花仙。  桃花仙人种桃树,又摘桃花卖酒钱。

酒醒只在花前坐,酒醉还来花下眠。  半醒半醉日复日,花落花开年复年。

但愿老死花酒间,不愿鞠躬车马前。  车尘马足富者趣,酒盏花枝贫者缘。

若将富贵比贫贱,一在平地一在天。  若将贫贱比车马,他得驱驰我得闲。

世人笑我太疯癫,我笑他人看不穿。  不见五陵豪杰墓,无花无酒锄作田。


晚钟

洛兵

晚钟敲响从城市那边  飞来宁静的翅膀
有家的人请回你们的家  没家的人请走进那夕阳

晚钟敲响从夕阳的眼中  流出宁静的凄凉
爱我的人请过来一起唱  恨我的人请躲开那月光

晚钟敲响从新月的梦里  落下宁静的忧伤
生者依旧习惯地擦去泪水  逝者已矣请返回你们的天堂

晚钟敲响从天堂上面  传来星空的回荡
醒来的人请守好你们的梦想  沉睡的人请把一切遗忘


当蜘蛛网无情地查封了我的炉台 当灰烬的余烟叹息着贫困的悲哀
我依然固执地铺平失望的灰烬 用美丽的雪花写下:相信未来

当我的紫葡萄化为深秋的露水 当我的鲜花依偎在别人的情怀
我依然固执地用凝霜的枯藤 在凄凉的大地上写下:相信未来

我要用手指那涌向天边的排浪 我要用手掌那托住太阳的大海
摇曳着曙光那枝温暖漂亮的笔杆 用孩子的笔体写下:相信未来

我之所以坚定地相信未来 是我相信未来人们的眼睛
她有拨开历史风尘的睫毛 她有看透岁月篇章的瞳孔

不管人们对于我们腐烂的皮肉 那些迷途的惆怅、失败的苦痛
是寄予感动的热泪、深切的同情 还是给以轻蔑的微笑、辛辣的嘲讽

我坚信人们对于我们的脊骨 那无数次的探索、迷途、失败和成功
一定会给予热情、客观、公正的评定 是的,我焦急地等待着他们的评定

朋友,坚定地相信未来吧 相信不屈不挠的努力
相信战胜死亡的年轻 相信未来、热爱生命!
