V. UNDERSTANDING GRAMMAR: NARRATIVE PRESENT
A.
Read about the narrative present
Although all of the events in this time line occurred in the past, you will notice
that the verbs are in the present tense. When writers
tell a story in the present
tense, it’s called the narrative present. It’s used to make events sound more
immediate—as if they are happening now—and can make a story sound more
interesting. People often use the narrative present in speaking, and it’s often
used in journalistic writing.
Look at the charts to review the form of present tense statements.
