This document discusses the use of the present continuous tense in English. It describes four main uses: 1) to express actions happening now, 2) actions in progress now that may extend over a longer period of time, 3) actions that will happen in the near future, and 4) to express irritation with repetitive actions when used with words like "always." It also notes certain verbs that cannot be used in the present continuous form and provides examples of adverb placement and active/passive voice constructions.
