Final answer:
Before a timed reading, Denise should warm up by reading the text she'll be timed on to enhance her familiarity with the content. There's no strict rule on how long the warm-up should be, but it should be enough to make her comfortable. Reading the text thoroughly at least three times is a good practice for preparation.
Step-by-step explanation:
Before doing a timed reading, Denise should warm up by reading the text for the timed reading to get familiar with the content and structure. Warming up before the actual reading can help Denise increase her reading speed and comprehension when it's time for the real challenge. There's no set minimum time for such a warm-up, but it should be sufficient enough to get comfortable with the material.
Additionally, reading the entire piece three times as a rough draft, including the introduction and conclusion, is a good practice for getting a deep understanding of the text. This process can help in identifying any challenges with the flow or understanding of the text before the timed session begins.
Ultimately, the key is for Denise to feel prepared and not rushed when she starts the timed reading. A warm-up can significantly aid in her overall performance.
