Because it is conventional to write about literature in the present tense and because literary works often use other tenses, you need to exercise some care when weaving quotations into your own text. A first-draft attempt may result in an awkward shift, as it did for one student who was writing about Nadine Gordimer’s short story “Friday’s Footprint.”
TENSE SHIFT
When Rita sees Johnny’s relaxed attitude, “she blushed, like a wave of illness” (159).
To avoid the distracting shift from present to past tense, the writer had two choices:
to paraphrase the reference to Rita’s blushing and reduce the length of the quotation
to change the verb in the quotation to the present tense, using brackets to indicate the change.
REVISED
When Rita sees Johnny’s relaxed attitude, she is overcome with embarrassment, “like a wave of illness” (159).
REVISED
When Rita sees Johnny’s relaxed attitude, “she blushe[s], like a wave of illness” (159).
Using brackets around just one letter of a word can seem pedantic, so the writer chose the first revision.
