大学英语四级考试练习卷、阅读理解Passage 1Three Kinds of FatigueFatigue is one of the most common complaints brought to doctors, friends, and relatives.

But probably more people complain of fatigue today than in the days when hay was baled by hand and laundry scrubbed on a washboard.The causes of modern-day fatigue are diverse and only rarely related to excessive physical exertion. The relatively few people who do heavy labor all day long almost never complain about being tired, perhaps because they expect to be.

Usually other symptoms besides fatigue are present that suggest the true cause.Even after an illness has passed, you're likely to feel dragged out for a week or more. Take your fatigue as a signal to go slow while your body has a chance to recover fully even if all you had was a cold. Pushing yourself to resume full activity too soon could lead to a relapse （旧病复发）and almost certainly will prolong our period of fatigue.Even though illness is not frequent cause of prolonged fatigue, it's very important that it not be overlooked. Therefore, anyone who feels drained of energy for weeks on end should have a thorough physical check-up. But even if nothing shows up as a result of the various medical tests, that doesn't mean there's nothing wrong with you.Psychological. Emotional problems and conflicts, especially depression and anxiety, are by far the most common causes of prolonged fatigue. Fatigue may represent a defence mechanism that prevents you from having to face the true cause of your depression, such as the fact that you hate your job. It is also your body's safety mechanism for expressing repressed emotional conflicts, such as feeling trapped in an ungrateful role or an unhappy marriage. When such feelings are not expressed openly, they often come out as physical symptoms, with fatigue as one of the most common manifestations. "Many people who are extremely fatigued don't even know they're depressed, z/ Dr. Bulette says. “They' re so busy distracting themselves or just worrying about being tired that they don't recognize their depression. There is a great deal you can do on your own to deal with both severe prolonged fatigue and those periodic washed-out feelings. Vitamins and tranquilizers （镇 静剂） are almost never the right answer, sleeping pills and alcohol are counterproductive, and caffeine is at best a temporary solution that can backfire with abuse and cause life-disrupting symptoms of anxiety. Instead, you might try: DietIf you eat a small breakfast or none at all, you re likely to experience mid-morning fatigue, the result of a drop in blood sugar, which your body and brain depend on for energy. For peak energy in the morning, be sure to eat a proper breakfast, low in sugar and fairly high in protein, which will provide a steady supply of blood sugar throughout the morning. Coffee and a doughnut are almost worse than nothing, providing a brief boost and then letting you down with a thud. ExerciseContrary to what you may think, exercise enhances, rather than saps, energy. Regular conditioning exercises, such as jogging, cycling, or swimming, help you to resist fatigue by increasing your body's ability to handle more of a work load. You get tired less quickly because your capability is greater. Exercise also has a well-recognized tranquilizing effect, which helps you work in a more relaxed fashion and be less dragged down by the tensions of your day. At the end of a day exercise can relieve accumulated tensions, give you more energy in the evening, and help you sleep more restfully.SleepIf you know you're tired because you haven't been getting enough sleep, the solution is simple: Get to bed earlier. There's no right amount of sleep for everyone, and generally sleep requirements decline with age. Find the amount that suits you best, and aim for it. Insomnia（失眠）and other sleep disorders should not be treated with sleeping pills, alcohol, or tranquilizers, which can actually make the problem worse. Know yourselfTry to schedule your most difficult jobs for the time of day when you're at your peak. Some are "morning people" who tire by mid-afternoon; others do their best work in the evening. Don't overextend yourself, trying to climb the ladder of success at a record pace or to meet everyone's demands or expectations. Decide what you want to do and what you can handle comfortably, and learn to say no to additional requests. Recognize your energy cycles and plan accordingly. Many women have a low point premenstrually, during which time extra sleep may be needed and demanding activities are particularly exhausting. , Take breaks No matter how interesting or demanding you work, you 11 be able to do it with more vigor if now and again you stop, stretch, and change the scenery. Instead of coffee and a sweet roll on your break, try meditation, yoga, callisthenics （ft 美操） ,or a brisk walk. Even running up and down the staircase can provide refreshment from a sedentary （久坐的）job. If your job is physically demanding, relax in a quiet place for a while. The do-something-different rule also applies to vacation; "getting away from it all" for a week or two or longer can be highly revitalizing, helping you to put things in perspective and enabling you to take your job more in stride upon your return.1. According to the passage, it is hard for people to find causes of tiredness when they are leading a comfortable and convenient life.2.
