Certain instances of parallel structure are easy to understand. Compound subjects or objects, for example, are often the first types students put into use. A beginner can say, “Soup and pasta are my favorite foods.” or “I like TV and books.” Lists, either within a sentence or in bulleted form, tend to pose more challenges. I’ve often seen an incorrect mix of gerunds and base forms of verbs in a list of skills on resumes, for instance. Then come the correlative conjunctions, such as either…or. These structures are put into use at the intermediate level and above, and key to using them is understanding parallel structure.
Recognizing the need for exposure to and practice with parallel structure, I’ve created my How To_handout. It’s a writing activity that is designed for classroom use, but could easily be adapted for private lessons. I hope your upper level students will find it enjoyable to use.
