Frost's poetry did not attract attention in the United States at first. After his family moved to England in 1912, he continued to write poetry and was supported and encouraged by some British poets and the American poet Ezra Pound. , published the poetry collections "The Will of Youth" (1913) and "North of Boston" (1914), which were well received and attracted the attention of the American poetry community. He returned to the United States in 1915 and ran a farm in New Hampshire. His poetry became more and more famous, and he won the Pulitzer Prize four times in 1924, 1931, 1937, and 1943. He served as a teacher, poet-in-residence, and poetry consultant in several famous universities. In his later years he was an unofficial poet laureate of the United States. On his 75th and 85th birthdays, the U.S. Senate passed resolutions to pay tribute to him. His poetry is similar in form to traditional poetry, but not as pretentious as romantic and aesthetic poets. He does not pursue external beauty. His poems often begin with descriptions of New England's natural scenery or customs, and gradually enter a philosophical realm. His poems are unpretentious, yet delicate, subtle, and thought-provoking. The famous poem "White Birch Tree" writes that ordinary people always want to escape reality, but they must eventually return to reality. "Mending the Wall" writes that there are many tangible and invisible walls in the world that have no value in existence. In addition to short lyric poems, he also has some dramatic long narrative poems, which depict the spiritual outlook of rural characters in New England. The tone is relatively low and quite distinctive. In terms of rhythm, Frost likes to use various variations of traditional blank verse and sonnets, which has his own characteristics in rhythm.
Frost is often called an "alternative poet", which means that he was in a period of alternation between traditional poetry and modern poetry. He is also considered to be the two major centers of modern American poetry with Eliot.
Frost's famous poetry collections include "In the Mountains" (1916), "New Hampshire" (1923), "The Stream Going West" (1928), "Another Pasture" (1936), etc. In 1949, "The Complete Collection of Poems" was published, and new works have been published since then.
