Subject: Marsha's Error Correction of Verbs in the Past Time Frame
Title: My Daughter's
Dance Class
1. Original: My daughter dances every Sunday, but two Sundays ago,
since she feeling sick, I haven't taken her to her dance class.
Revision: My daughter dances every Sunday, but two Sundays ago, since
she [was feeling] sick, I [didn't take] her to her dance class.
Explanation: 1. The clause "she was feeling sick" should
use the past continuous because the sick feeling started before the decision
not to take her to class and it was continuing (it was in progress); the past
continuous requires two parts: WAS or WERE + VERB-ing. 2. The clause "I
didn't take her..." needs to use the simple past because it is a completed
past action; it is not related to the present
