There are only two different words at the beginning and end of the poem Rain Lane. This paper analyzes the reasons why the author adopts this writing method and its expression effect.

Standard answer: 13. Only the fourth line of these two poems uses two different words. The first section is "Meeting", which shows that "I, the goal I hope and pursue, have not yet appeared. The goal is "a lilac-like/sad girl". The five poems in the middle describe the experience of "I" and "girl" meeting and parting, and the last sentence is changed to "wandering", indicating that the past has passed, but this experience is still remembered by me from time to time and reappeared in my memory. In addition, from the structural point of view, the intention of the first and second sections makes the whole poem look neat and complete, with a long aftertaste.
