Important examples of fever in TOEIC

Vocabulary examples from the TOEIC test

In TOEIC vocabulary questions, fever is used to describe a high body temperature due to illness.

▪She took a day off because she had a fever.
▪She was sick because her body temperature was high.

Example of a confusing word: fervor (intense passion)

▪She took a day off because she had a fervor.
▪She was absent due to her intense passion.
"Fever" refers to an elevated body temperature often caused by illness, making "She had a fever" a correct and natural expression. "Fervor," on the other hand, means "intense passion" or "enthusiasm" and is not related to physical health. Using "fervor" in this context is grammatically incorrect and semantically inappropriate, as it suggests an emotional state rather than a medical condition. Thus, "fever" is the correct choice.

Grammar examples from the TOEIC test

Fever is a countable noun and is often used with 'a' or 'have'.

▪She has a fever today.
▪She has a high temperature today.
