This document discusses the uses of auxiliary verbs in Spanish. It explains that auxiliary verbs are used to avoid repetition, indicate if something is the same or different, and show interest or surprise in response questions. Auxiliary verbs are also used for emphasis in positive sentences, both in the present and past tense. The document also covers question tags, noting that they are formed with a positive auxiliary and negative verb or vice versa. Question tags are used to check information or ask another person to agree.
