The document discusses how to form the past tense of regular and irregular verbs in English. For regular verbs, the past tense is generally formed by adding "-ed" to the base verb. Some regular verbs have spelling changes in the past form. Irregular verbs have unique past tense forms that do not follow a set pattern, such as "go" becoming "went" and "see" becoming "saw". Examples are provided of commonly used regular and irregular verbs in their base and past tense forms.
