穷居寡人用，时忘四运周。
门庭多落叶，慨然知已秋。
新葵郁北牖，嘉穟养南畴。
今我不为乐，知有来岁不？
命室携童弱，良日登远游。
《酬刘柴桑》前两句“穷居寡人用，时忘四运周”说没有什么人与他来往，所以他有时竟然忘了HRef=https://www.xuegushici.com/list/siji/ target=_blank class=infotextkey>四季的节序HRef=https://www.xuegushici.com/list/bianhua/ target=_blank class=infotextkey>变化。然事实并非如此，诗人正是在知与不知中感受HRef=https://www.xuegushici.com/list/shengming/ target=_blank class=infotextkey>生命的意趣。之后吟道：“空庭多落叶，慨然知已秋。新葵郁北墉，嘉穗养南畴。今我不为乐，知有来岁不？命室携童弱，良日登HRef=https://www.xuegushici.com/list/yuanyou/ target=_blank class=infotextkey>远游。”此八句所写与前两句恰好相对，时忘四运与叶落知秋，多落叶与葵穗繁茂，甘心穷居与择日HRef=https://www.xuegushici.com/list/yuanyou/ target=_blank class=infotextkey>远游，此数者意象HRef=https://www.xuegushici.com/list/maodun/ target=_blank class=infotextkey>矛盾，却展现了HRef=https://www.xuegushici.com/list/shijian/ target=_blank class=infotextkey>时间的永恒性与HRef=https://www.xuegushici.com/list/shengming/ target=_blank class=infotextkey>生命的暂时性。由忘时乃知穷居HRef=https://www.xuegushici.com/list/guji/ target=_blank class=infotextkey>孤寂HRef=https://www.xuegushici.com/list/luomo/ target=_blank class=infotextkey>落寞；而枝头飘然而至的落叶，乃知HRef=https://www.xuegushici.com/list/qiutian/ target=_blank class=infotextkey>秋天的到来，HRef=https://www.xuegushici.com/list/shengming/ target=_blank class=infotextkey>生命的HRef=https://www.xuegushici.com/list/qiutian/ target=_blank class=infotextkey>秋天亦在浑然不觉中悄悄来临；墙角的新葵、南畴的嘉穗，虽暂时茂盛繁荣却犹似HRef=https://www.xuegushici.com/list/shengming/ target=_blank class=infotextkey>生命的晚钟难得长久，从而暗示HRef=https://www.xuegushici.com/list/shengming/ target=_blank class=infotextkey>生命的荣盛行将不再。因此诗人在穷居忘时之际又察其HRef=https://www.xuegushici.com/list/shengming/ target=_blank class=infotextkey>生命飞逝，择良日作此HRef=https://www.xuegushici.com/list/yuanyou/ target=_blank class=infotextkey>远游折射出HRef=https://www.xuegushici.com/list/shengming/ target=_blank class=infotextkey>生命的亮色。“今我不为乐，知有来岁不？”一句没有对来岁未知的恐怖，但有尽享今朝的HRef=https://www.xuegushici.com/list/xiongjin/ target=_blank class=infotextkey>胸襟。诗HRef=https://www.xuegushici.com/list/renqing/ target=_blank class=infotextkey>人情绪的宛转之变与物的荣悴之态，不能忘世的HRef=https://www.xuegushici.com/list/gankai/ target=_blank class=infotextkey>感慨之忧与对HRef=https://www.xuegushici.com/list/shengming/ target=_blank class=infotextkey>生命的达观之乐，交织成多层次的意义。
诗中以HRef=https://www.xuegushici.com/list/yinju/ target=_blank class=infotextkey>隐居躬耕的HRef=https://www.xuegushici.com/list/ziran/ target=_blank class=infotextkey>自然乐趣和HRef=https://www.xuegushici.com/list/rensheng/ target=_blank class=infotextkey>人生无常的HRef=https://www.xuegushici.com/list/daoli/ target=_blank class=infotextkey>道理来HRef=https://www.xuegushici.com/list/chouda/ target=_blank class=infotextkey>酬答刘柴桑，在淳朴祥和之中，诗篇流露着HRef=https://www.xuegushici.com/list/tianyuan/ target=_blank class=infotextkey>田园HRef=https://www.xuegushici.com/list/shenghuo/ target=_blank class=infotextkey>生活的乐趣。这首小诗共十句，虽然比较HRef=https://www.xuegushici.com/list/jianduan/ target=_blank class=infotextkey>简短，然而它内容醇厚。在写法上也比较独特，撇开与对方问答一类的应酬话，只写自己的感受、HRef=https://www.xuegushici.com/list/baofu/ target=_blank class=infotextkey>抱负与游兴，显得十分洒脱别样。在遣词造句上，粗线条的勾勒，并着墨点染，使全诗呈现出古朴淡雅的HRef=https://www.xuegushici.com/list/feng/ target=_blank class=infotextkey>风格，又洋溢着轻快明朗的HRef=https://www.xuegushici.com/list/ganqing/ target=_blank class=infotextkey>感情。
