Introduction to Exercise 3 - Using parallel structures in sentences
Grammar Explanation

•  Use parallel structures (the same type of words) whenever you write a list or comparison.  
  • Incorrect (and confusing): The proposal will provide several benefits, including creating jobs, crimes will be prevented, and reducing taxes.
  • Corrected (all the items in the list start with nouns ending in -ing): The proposal will provide several benefits, including creating jobs, preventing crime, and reducing taxes.
•  To create parallel structures, use the same grammatical forms (e.g., adjectives, nouns with -ing endings, prepositional phrases, clauses) in a list or comparison.
  • Example (four adjectives): The proposed law is not only unfair and unpopular, but also unnecessary and dangerous.
  • Example (three phrases with a noun with an –ing ending): Eating fruits and vegetables, exercising daily and getting enough sleep are some of the things each of us can do to maintain a healthy lifestyle.
  • Example (two prepositional phrases that are followed by a clause): For students, flexible working hours are helpful; however, for parents, a steady job is more important.
