In　order　to　optimize　the　integration　of　English　multimedia　resources　and　achieve　the　goal　of　sharing　English　teaching　resources　in　education,　this　article　reconstructs　the　traditional　college　English　curriculum　system.　It　divides　professional　English　into　learning　modules　according　to　different　majors　integrating　public　health　teaching　resources.　How　optimize　the　integration　of　English　multimedia　resources　and　achieving　the　goal　of　sharing　English　teaching　resources　(ETR)　is　the　main　direction　of　English　teaching　reform　during　the　current　COVID-19　pandemic.　An　English　multimedia　teaching　resource-sharing　platform　is　designed　to　extract　feature　items　from　multimedia　teaching　resources　using　the　ID3　information　gain　method　and　construct　a　decision　tree　for　resource　push.　In　resource　sharing,　a　structured　peer-to-peer　network　is　used　to　manage　nodes,　query　location　and　share　multimedia　teaching　resources.　The　optimal　gateway　node　is　selected　by　calculating　the　distance　between　each　gateway　node　and　the　fixed　node.　Finally,　a　collaborative　filtering　(CF)　algorithm　recommends　Multimedia　ETR　to　different　users.　The　simulation　results　show　that　the　platform　can　improve　the　sharing　speed　and　utilization　rate　of　teaching　resources,　with　maximum　throughput　reaching　12　Mb/s　and　achieve　accurate　recommendations　of　ETR.　©　2023　Jiang　and　Ma
