Grammar Explanation

•  When expressing similar (or contrasting) ideas within a sentence or in longer passages, it is a good idea to repeat the same grammatical structure. The repetition of grammatical forms is called parallelism. Parallel structures help the reader recognize similarities and help produce cohesion within a text. 
  • Example: Previously, students were required to take two years of a foreign language; now, they are permitted to take only one year.
•  When listing two or more ideas in a series, use parallel structures.
  • Example: It is important for students to learn how to organize their time, to study effectively and to ask for help.
  • Example: 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.
•  When making a comparison, use the same grammatical structures for the elements being compared. 
  • Example: It is easier to recognize the problem than to solve it.
  • Example: Truth is stranger than fiction.
