两章的内容都是回应首段中的“皈依在路上”——强调“付诸行动”。“三路车”同“北门梯”构成点与面的关系。此文还需要升格:只就其中一章展开写,独自成文。 The contents of both chapters are in response to the paragraph in the first paragraph “convert to the road” - emphasize “into action ”. “Three-car ” with the “North Gate ladder ” constitute the relationship between the point and the surface. This article also needs to be upgraded: only one of the chapters started writing, alone.
