The document discusses the simple present tense in English. It explains that the simple present tense is used to describe habits, routines, and general truths. There are only two verb forms in the simple present - one ending in -s for third person singular subjects like he/she/it, and one without -s for other subjects. Forming questions in the simple present puts the subject after do/does plus the base verb form. Examples are provided to illustrate affirmative, negative, and interrogative simple present sentences.
