The document discusses the simple past tense in English. It notes that regular verbs are formed by adding "-ed" to the base verb, while irregular verbs change form from the present to past tense. It also covers forming negative sentences using "didn't" plus the base verb and interrogative sentences using "did" plus the base verb. Examples are provided to illustrate conjugating regular and irregular verbs in the simple past tense, as well as forming negatives and interrogatives.
