问题     Basically, there are three types of fatigue: physical, pathological (病例的), and psychological. As you might suspect, each differs significantly from the others.
    When you exercise your body, you produce waste products. Muscles, for example, discard lactic add (|Lg£) into the blood; cells dump in carbon dioxide. When these wastes reach a certain level in the blood, the brain is notified and your activity level drops. Excess wastes in the muscles may produce soreness. If the blood of a physically fatigued animal is injected into a rested animal, it will produce fatigue. The solution to this type of fatigue is simple—rest. That should revive you; if it doesn’t, another cause should be sought.
    Have you ever become involved in so many activities that you had to be in two places at once? This is what happens when your body has a disease. The cells are overtaxed and cannot keep up with both fighting the disease and keeping you active. The result is fatigue. Some communicable diseases like the flu and colds are notorious for draining your energy. Other non-communicable diseases, like anemia (贫血), drain you because you are lacking an important body ingredient. Being overweight can cause pathological fatigue. It should be obvious that this type of fatigue is not going to go away without treatment. In a way, pathological fatigue is a lifesaver. It lets you know something is wrong and that you need rest. Even a poor diet can produce pathological fatigue. Frequently, people who go on crash diets develop pathological fatigue, and if the diet is not improved, they may do physical harm to their bodies.
    Here is the most common type of fatigue. Almost everybody experiences it now and then. Often, the cause is an emotional war you are waging with yourself or those around you. Some of these familiar factors can bring on psychological fatigue: worries, stress, lack of exercise, boredom, depression. If you know someone with psychological fatigue, would you advise him to rest? No way! That might be fine for our other types of fatigue, but for this one, it’s deadly. If you are ever going to be able to cope with stress, depression, or worry, you need oxygen in your cells and a more optimistic attitude. Get out of the chair and do something! Believe it or not, many people throw themselves into physical labor like cleaning or carpentry to "de-fatigue" themselves. If you find yourself in a particularly stressful situation that you can’t physically escape, escape mentally. When fatigue continues, maybe you need to get to the root of the problem.
Which of the following statements is TRUE about psychological fatigue?

选项 A、Medical attention is necessary for doing away with it.
B、It is more serious than the other two kinds of fatigue.
C、It can be eased by doing physical exercises.
D、It is caused by lack of oxygen in blood cells.

答案C

解析 根据题干关键词psychological fatigue定位到末段。原文这两句表示physical labor有助于消除心理疲劳,选项C中的physical exercises也是physical labor的一种,因此选项C是正确的推断。末段在介绍心理疲劳的时候并没有提及与选项A中的Medical attention (医疗护理)有关的信息;作者只是将心理疲劳的治疗方法与其他两种疲劳分别做了介绍,并没有比较它们的严重性,因此选项B不正确;引起心理疲劳的原因在本段第4句提到,选项D并不是原因之一,另外,原文提到治疗心理疲劳需要给细胞供氧,由此可见,细胞缺氧只是症状。不是原因。
