You must use Consistent Verb Tenses in paragraphs and when speaking
Consider how to correctly use verb tenses in paragraphs/stories, when we are writing AND speaking. One important idea is that we choose what the time/tense of our story/paragraph is from our Topic Sentence. Then ALL of the sentences must match that time/tense, unless there is a clear reason why we need to change the tense. For example, if I said, “Today I am Zooming with my ESL class, but yesterday I Zoomed with my Speech class.” That sentence talks about 2 different days/times, and so my verbs must reflect/match that.
The Present Perfect = an action that happened in the past, but when it happened is not important, for 3 possible reasons: 1. maybe I don’t remember when it happened; 2. maybe it repeated in the past; 3. maybe it didn’t stop, so it started in the past but MAYBE continues in the present.
