19、the Chinese Alligators are in our hands 揚子鱷未來的命運掌握在人的手里 The fate of the Chinese Alliga Giant Panda Giant Panda詩歌是一種憂郁的媒體，而詩人的使命是孤獨的。垂下的頭顱只是為了讓思想揚起，你若有一個不屈的靈魂，腳下就會有一片堅實的土地。 只要春天還在我就不會悲哀縱使黑夜吞噬了一切太陽還可以重新回來只要生命還在我就不會悲哀縱使陷身茫茫沙漠還有希望的綠洲存在只要明天還在我就不會悲哀冬雪終會悄悄融化春雷定將滾滾而來 我和這個世界不熟。 這并非是我安靜的原因。 我依舊有很多問題， 問南方，問故里，

20、問希望，問距離。我和這個世界不熟。 這并非是我絕望的原因。 我依舊有很多熱情， 給分開，給死亡，給昨天，給安寂。 我和這個世界不熟。 這并非是我虛假的原因。 我依舊有很多真誠， 離不開，放不下，活下去，愛得起。 我和這個世界不熟。 這并非是我孤寂的原因。 我依舊有很多訴求， 需慰藉，待分享，惹心煩，告訴你。 我和這個世界不熟。 這并非是我冷漠的原因。 我依舊有很多動情， 為時間，為白為天黑，畏天命。那時我們有夢，一切都是命運，一切都是煙云一切都是沒有結(jié)局的開始，一切都是稍縱即逝的追尋，一切歡樂都沒有微笑，一切苦難都沒有淚痕，一切語言都是重復(fù)，一切交往都是初逢，一切愛情都在心里，一切往事都在夢中

21、，一切希望都帶著注釋，一切信仰都帶著呻吟，一切爆發(fā)都有片刻的寧靜，一切死亡都有冗長的回聲。 走吧，落葉吹進深谷，歌聲卻沒有歸宿。走吧，冰上的月光，已從河面上溢出。走吧，眼睛望著同一片天空，心敲擊著暮色的鼓。走吧，我們沒有失去記憶，我們?nèi)ふ疑暮Ｗ甙?，路呵路，飄滿了紅罌粟。 我不相信，生活是沼澤，我不相信，生命旅途不能一路高歌；我不相信，成長是懦弱，我不相信，雙手握不住執(zhí)著的繩索。人生一世，草木一秋，我們就跟大樹上的葉子一樣，早晚會枯黃隕落。樹葉雖小但見證了春秋，既目睹了繁花似錦，也目睹了大樹凋零。我們都是很相似的樹葉，因為人生就是這樣，生老病死是誰都要經(jīng)過的。 如果你是條船，漂泊就是你的

22、命運，可別靠岸。誰校對時間 誰就會突然老去 雖生猶死的寂寞讓生命都凋零了人總要慢慢成熟，將這個浮華的世界看得更清楚，看穿偽裝的真實，看清隱匿的虛假，很多原本相信的事便不再相信。但是，要相信，這個世界里美好總要多過陰暗，歡樂總要多過苦難，還有很多事，值得你一如既往的相信。人生不能像做菜，把所有的料都準備好了才下鍋 卑鄙是卑鄙者的通行證高尚是高尚者的墓志銘 早上，燦亮的陽光撲進來，他還睡著。我打開窗簾，看窗外那一片平凡而現(xiàn)實的風景。心想，在平凡和現(xiàn)實里，也必有巨大的美的可能吧。那時我們還年輕。穿過殘垣斷壁蒼松古柏，我們來到山崖上。沐浴著夕陽，心靜如水，我們向云霧飄蕩的遠方眺望。其實啥也看不到，生活的悲歡離合遠在地平線以外，而眺望是一種青春的姿態(tài)。 才子當然心里冰雪般的透徹：有些事，只能一個人做。有些關(guān)，只能一個人過。有些路啊，只能一個人走。 不必向我訴說春天我的心里并沒有秋寒不必向我解釋色彩我的眼里自有一片湛我嘆世事多變幻世事望我卻依然
