中文摘要：

岳麓书院所藏秦简《占梦书》简2-3的“必顺四时而豫其类”的“豫”理解为“顺”于传世文献有征，或许不需要破读为它字；简5的“口山”当释做“分山”，其义可能指“开山”；简44背面残文当为“梦书”二字，与此篇篇题关系密切。

英文摘要：

It is more proper to explain the character 豫 of 必顺四时而豫其类 as 顺, recorded on the 2nd and 3rd strip of Chapter Zhan Meng Shu of the Yuelu Qin Bamboo Strip Manuscripts, rather than other characters, according to an analysis with historical documents. The word 口山 should be read as 分山, which means to split a mountain. The two characters wrote on the back of the 44th strip are 梦书, has close relationshio with the theme of the chapter.
