Step-by-step explanation:
Henry David Thoreau's account of living in the woods, as presented in the query, is told primarily in the past; first-person point of view. This narration style is evidenced through the use of first-person pronouns and past tense verbs in the descriptions of his experiences. Thoreau's writings reflect his personal actions and observations, like building his own cabin at Walden Pond and formulating ideas about living a simple and unencumbered life, which are characteristic of a first-person narrative. Additionally, his reflections on life are presented as events that have already occurred, which is indicative of a past tense narrative.
