1.The author uses the words ",fair" and "worn" to contrast the speaker's hopefulness with the doubt he feels later.
2.The author uses the words ",other" and "same" to contrast the speaker's doubt with the confidence he feels later.
3.The author uses the words ",took" and "better" to show the speaker's greed and the pride he feels later.
4.The author uses the words ",grassy" and "worn" to contrast the speaker's love for nature with his later disgust.
