It provides examples of verbs in the -ing form in the present progressive, discusses time expressions that can be used with the tense, provides questions and negative forms, and discusses some verbs that cannot be used in the present progressive because they describe a state of being rather than an action. It also notes some verbs that can be used either statively or actively.
