heres a summary of it http://www.shmoop.com/hollow-men/summary.html hope that helps, i don't understand rhapsody or preludes
Thanks! I can help a bit with rhapsody

Here are a couple of paragraphs I wrote in a practice essay:
ON MODERNITY: Through symbolism and metaphor, Eliot effectively explains to readers the impact of modernity upon their lives and relationships, as evident through the metaphor of “a broken spring in a factory yard, /Rust that clings to the form that the strength has left.” The spring symbolizes our world, with the rust of modernity promoting its decay. Thus, the reader is presented with an austere assessment of society for them to further their understanding of their own – in Eliot’s opinion, unfulfilling – role within it.
ON ISOLATION: Within Rhapsody, an isolated atmosphere is presented through the running motif of time, in order to convey to the reader, the narrator’s isolation, while he explores the streets alone at night. Eliot’s use of personification, such as the lamp who “sputtered” and “muttered,” represents humanity’s breakdown in communication, whereby ironically the inanimate objects are the most alive of figures within Rhapsody. Therefore, through Prufrock and Rhapsody Eliot effectively discusses the impact of isolation upon the relationship between an individual and society, through presenting it as a barrier inhibiting connection.
