This document provides pronunciation tips for the "-ed" endings in regular past tense verbs in English. It explains that there are three main pronunciations: /t/, /d/, and /id/. The /t/ pronunciation is used after voiceless sounds like p, t, k, f, s, ch, and sh. The /d/ pronunciation is used after voiced sounds like b, g, v, z, j, m, n, ng, l, r, and vowels. Verbs ending in d or t take the /id/ pronunciation. Examples are provided to illustrate the different rules. Mastering these pronunciation patterns can help ESL students with producing the past tense correctly in English.
