本文通過比較三版《古代漢語》教材,認為選文《左傳·鄭伯克段于鄢》的“完聚”一詞中間應句讀,作“完、聚”;“完”“聚”的解釋應採納王力版和郭錫良版《古代漢語》教材的觀點,即“完,修葺,指修城。聚,指聚集百姓。”關鍵詞:《左傳》;《古代漢語》;《春秋左傳注》;完聚 By comparing the three versions of “Ancient Chinese” teaching materials, we think that the sentence “Zuo Zheng Cheng Bok Duan Yu Yan” should be read in the middle of the sentence, “End, Poly”, “End” “Poly ” explanation should adopt Wang Li version and Guo Xiliang version of “Ancient Chinese” teaching material point of view, that is, “finish, repair, refers to the repair city. Poly refers to the aggregation of people.” Keywords: “Zuo Zhuan”; “Ancient Chinese”; “Spring and Autumn Annals Note”;
