The document discusses different types of sentence fragments and provides examples. There are three main types of fragments discussed: 1) those without a subject, 2) those without a verb, and 3) dependent clauses that cannot stand alone as a complete sentence. For each type of fragment, examples are given along with a revision that fixes the fragment by adding either a subject, verb, or combining the dependent clause with an independent clause to form a complete sentence. The purpose is to explain what constitutes a sentence fragment and provide guidance on how to identify and correct different kinds of fragments.
