Imagism请帮忙给出正确答案和分析 谢谢！

正确答案：Imagism is a literary movement which came into being in Britain and U. S. around 1910 as a reaction to the traditional English p6etry to express the sense of fragmentation and dislocation. The imagists with Ezra Pound leading the way hold that the most effective means to express these momentary impressions is through the use of one dominant image. Imagism is characterized by the following three poetic principles; i) direct treatment of subject matter; ii) economy of expression; iii) as regards rhythm to compose in the sequence of the musical phrase not in the sequence of metronome. Ezra Pound' s ' In a Station of the Metro' is a well-known imagist poem.
