Introduction to Exercise 1
Sentence with grammar mistakes

Roll your mouse over the sentence to see it fixed.
Grammar Explanation

•  Use the present or past tenses consistently, both within one sentence and from one sentence to the next.
  • Example: After deliberating for a whole day, the jury acquitted the defendant. That made the prosecuting attorney furious and he vowed to appeal the verdict.
•  If the situation you are writing about requires a change of tense, use a time expression to alert your reader.
  • Example: Whenever the economy is in bad shape, incumbent presidents have a hard time winning an election. In 1992, President George Bush lost the election because voters were nervous about the weak economy.
•  When writing about events or ideas presented by another writer in stories or articles, use the present tense.
  • Example: In an article published in a sociology journal two weeks ago, the author discusses several factors that contribute to the alarming rise in teenage pregnancy.
