The document discusses verb tenses in English. There are three simple tenses: present, past, and future. The present tense follows rules about adding "s" or "es" to verbs depending on their ending when the subject is singular. The past tense typically adds "ed" but has special rules for doubling consonants or dropping "e". The future tense uses the basic verb form with the helping verbs "will" or "shall".
