阅读理解 We've all heard exercise helps you live longer. But a new study goes one step further, finding that a sedentary(久坐不动的) lifestyle is worse for your health than smoking and heart disease. Dr. Wael Jaber, a doctor at the Cleveland Clinic and senior author of the study, called the results "extremely surprising." "Being unfit in an exercise stress test has a worse prognosis(预后), as far as death, than being a smoker," Jaber told CNN. "We've never seen something as noticeable as this and as objective as this." "It should be treated almost as a disease that has a prescription, which is called exercise," he said. Researchers studied 122,007 patients who took exercise stress tests at Cleveland Clinic between January 1, 1991 and December 31, 2020 to measure death rate relating to the benefits of exercise and fitness. Comparing those with a sedentary lifestyle to the top exercise performers, he said, the risk associated with death is "500% higher." What made the study so unique, beyond the number of people studied, he said was that researchers weren't relying on patients self-reporting their exercise. "This is not the patients telling us what they do," Jaber said. "This is our testing them and figuring out objectively the real measure of what they do." Researchers have always been concerned that "ultra(高强度的)" exercisers might be at a higher risk of death, but the study found that not to be the case. The benefits of exercise were seen across all ages and in both men and women, "probably a little more noticeable in females," Jaber said. "Whether you're in your 40s or your 80s, you will benefit in the same way." （1） Which statement is true according to the study? A . High levels of exercise can cause higher death rate. B .
