The document provides instruction on forming the past simple tense in English. It discusses regular and irregular verbs. For regular verbs, the simple past tense is formed by adding "-ed" to the base verb. For irregular verbs, the form changes in a non-standard way, such as "speak" becoming "spoke". Examples are provided of using the past simple tense to describe completed actions and a sequence of past events. The formation of negative sentences and yes/no questions in the past simple tense is also explained.
