Is Your Life Worth 30 Minutes a Day Don’’t be afraid of the E word ― it could mean your survival. People who aren’’t engaging in regular exercise can reap significant health benefits if they accumulate 30 minutes of moderate-intensity physical activity most days of the week. What can help prevent stroke (中风), heart disease and some cancer What can lift depression, ease arthritis (关节炎) pain and increase both the length and quality of life ― to name just a few of its benefits "If packed into a pill," sums up Dr. Robert Butler, former director of the National Institute on Aging, "it would be the single most widely prescribed (写处方) and beneficial medicine in the nation. "Best of all, it is free and available to everyone." Exercise Can Help People Stay Healthy Give up The answer is the E word: exercise. But you don’’t have to change into gym shorts or, heaven forbid, sweat for an hour. Instead, the U.S. Surgeon General’’s report Physical Activity and Health offers this simple exercise prescription: people who aren’’t engaging in regular exercise can reap significant health benefits if they accumulate 30 minutes of moderate-intensity physical activity most days of the week. Americans Expend Much Less Energy and Time on Exercise Americans today expend much less energy than did previous generations, perhaps as much as a few hundred calories per day less. All the "advances" that make our lives easier ― like e-commerce (电子商务) , and automatic doors ― contribute to the current epidemic (流行病) of obesity (肥胖) and related disease. Experts say that if you expend just ten extra calories a day by being more active, over a year you can lose a pound ― mostly fat. And if you burn 150 extra calories a day ― the equivalent of a 30-minutes’’ walk ― in a year that’’s ten pounds. (If you also eat 150 calories less ― that’’s about half a candy bar ― you could lose an additional ten pounds.)The sad fact is that only about 15 percent of American adults engage regularly in vigorous physical activity for at least 20 minutes three times a week. More than 60 percent are not regularly physically active, and 25 percent are totally sedentary (久坐的). The Benefit of Moderate Exercise Yet the benefits of moderate exercise are amazing. Consider how exercise helps the following: diabetes (糖尿病) . The number of Americans diagnosed with diabetes has increased six fold since 1958, to a record high of ten million. This alarming rise is linked to our expanding waistlines, junk food diet and inactivity. Some experts feel that the most common form of diabetes is preventable with a proper diet ― and regular activity. In diabetics, the hormone insulin (荷尔蒙胰岛素) does not properly regulate glucose (葡萄糖) levels in the blood. When people exercise, the body fuels the activity by taking glucose out of their blood to use for energy. Exercise Can Help Patients Suffering from the Following Diseases Heart Attacks and Stroke. One of the simplest, safest, least expensive and most effective strategies for improving heart health is frequently neglected: exercise. It reduces blood pressure and can help raise the level of "good" cholesterol (胆固醇) , while lowering "bad" cholesterol when combined with dietary changes. Remember: for every one percent reduction in blood cholesterol, the occurrence of coronary (冠状动脉的) heart disease is reduced by two percent. Moreover, people who exercise one hour per day cut their risk for stroke nearly in half, according to a study of 11,130 Harvard University alumni (男女校友). Mental Health. When asked why she started swimming during her freshman year at Boston University, world-class endurance swimmer Julie Ridge replied, "It was a mental thing." While sedentary people may assume that working out is about looking good, habitual exercisers like Ridge know that it is largely about feeling good. A growing body of research shows that physical activity does, indeed, exert a "feel good" effect that can work as a powerful treatment for depression. Arthritis. Many people ― including some physicians ― still haven’’t heard the new message that exercise can help people with arthritis now affecting nearly 43 million Americans. "We’’ve come from thinking that physical fitness was impossible for people with arthritis to know that exercise is one of the best ways to manage their disease and minimize their disability," says Marian Minor, an associate professor of Physical therapy at the University of Missouri, Columbia. Exercise can reduce pain by keeping joints (关节) flexible and the muscles around the joints strong. A person with arthritis who has other medical conditions or a lot of pain should get a physician’’s referral (建议) to a physical therapist who can design an individualized exercise program. Cancer. Each year over a million Americans learn they have cancer ― the second leading cause of death in the Unites States after heart disease. In 1996 the American Cancer Society added regular physical activity to the list of preventive measures it advocates. According to one large study of people at various levels of fitness, the least fit men died from cancer at a rate more than three times higher than that of the most fit men. And, notes Informed Decisions, the American Cancer Society’’s guide to the disease, an earlier study found "the least fit women had fully 16 times the cancer death rate of the most fit women." Scientists still don’’t know the precise mechanisms by which exercise appears to exert an "anticancer" effect, but current thinking points to physical activity’’s effect on the immune and endocrine (内分泌的) system. So Choose to Move. Stop viewing exercise as a "workout" and start thinking of it as play ― a welcome daily recess (暂歇) that frees your body from the confines of its workaday routines. And if you have any health concerns, you should, of course, consult a physician first.In a way, some modern conveniences result in people’’s obesity and related diseases. A．YB．NC．NG

题目解答
答案
A
解析
考查要点：本题主要考查学生对文章细节的理解能力，需要判断文中是否明确提到现代便利设施与肥胖及疾病之间的因果关系。
解题核心思路：
- 定位关键段落：文章中明确提到现代便利设施（如电子商务、自动门等）对健康的影响。
- 提取关键信息：文中直接指出“现代便利设施使生活更轻松，但导致肥胖及相关疾病的流行”。
- 判断逻辑关系：题目中的因果关系（现代便利→肥胖）与原文表述完全一致。
破题关键点：
- 锁定原文原句：需找到“现代便利设施导致肥胖”这一表述，确认其是否为文章明确观点。
关键句定位：
文章第3段明确指出：
“All the 'advances' that make our lives easier — like e-commerce and automatic doors — contribute to the current epidemic of obesity and related disease.”
（所有使生活更轻松的“进步”——如电子商务和自动门——都助长了肥胖及相关疾病的流行。）
逻辑分析：
- 因果关系：文中用“contribute to”直接说明现代便利设施是肥胖和疾病流行的原因。
- 题目表述：“一些现代便利设施导致肥胖和相关疾病”与原文完全一致，因此答案为Y（正确）。
