The document discusses how to form questions in English. It explains that for most verbs, questions are formed with a question word, auxiliary verb, subject, main verb, and the rest of the question. For "be" verbs, the question word is followed by the verb and then the subject. "Who" questions are also formed differently, with "who" followed by the verb and then the rest of the question. The document provides examples to illustrate these three patterns for forming questions in English.
