The document discusses the simple past tense of regular verbs in English. It explains that the simple past is used to talk about finished past events and is formed by adding "-ed" to the base form of the verb. For verbs ending in a consonant plus "y", the "y" is changed to "i" before adding "-ed". For verbs with a vowel followed by two consonants, the last consonant is doubled. Examples of affirmative, negative, and interrogative sentences in the simple past are provided. A table is included to show the simple past form of sample regular verbs. Exercises are given to practice using verbs in the simple past correctly in sentences.
