This document discusses the simple past tense in English. The simple past is used to talk about actions that are completed in the past. It can be used with time expressions like "last week" or "yesterday." Regular verbs are conjugated by adding "-ed" to the infinitive form. There are some exceptions for verbs ending in consonant-vowel-consonant or verbs ending in "y." Several examples are provided to demonstrate using the simple past tense with regular and irregular verbs.
