8.27 -- Quick Revision: Sentence Improvement


Approach (5 Steps)

  1. Read the full sentence; focus on the bold/underlined part.
  2. Identify the problem (grammar, idiom, wordiness, modifier, parallelism).
  3. Predict the correction mentally.
  4. Match your prediction with the options.
  5. Verify by reading the full sentence with the replacement.

Most Common Improvement Types

TypeWhat to FixExample
TenseMatch tense to time markers; "since" = perfect"is working since" --> "has been working since"
PrepositionUse correct preposition for verb/adjective"discussed about" --> "discussed"
Subject-Verb AgreementVerb must match subject (not nearest noun)"The news are" --> "The news is"
WordinessReplace wordy phrases with concise equivalents"due to the fact that" --> "because"
ModifierOpening phrase must modify the following subject"Walking fast, the bus was caught" --> "Walking fast, he caught the bus"
ParallelismList items in same grammatical form"reading, to swim, painting" --> "reading, swimming, painting"
VoicePrefer active over unnecessary passive"was written by her" --> "she wrote"
