试题内容
    Basically, there are three types of fatigue: Physical, pathological (由疾病引起的), 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 acid (乳酸) 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 (木工活) to "defatigue" 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.

  • A.The consequences of fatigue.

  • C.The dangers of fatigue.
  • D.Types of fatigue.
  • 解题思路:文章第1句即全文的主题句:从根本上来说,疲劳分为三种:身体上的、由疾病引起的以及  心理上的。由此可见,本文主要谈论了这三种疲劳。A.“疲劳的结果”,即疲劳的表现,与第1段意思不  符,故排除;文章第2段提到,身体感到疲劳时,休息是最好的解决办法,B.与之意思相符,但并非整篇  文章论述的中心,故排除C.文中未提及。
2.[单选题]How does the author see pathological fatigue?
  • A.Some pathological fatigue is good for people.
  • B.Everyone is vulnerable to pathological fatigue.
  • C.Pathological fatigue needs no medical attention.
  • D.Pathological fatigue harms people psychologically only.
  • 解题思路:第3段倒数第3、4句提到,在某种程度上,疾病引起的疲劳能救人一命。它让你注意到你的  身体出了问题,需要休息。也就是说,疾病引起的疲劳感实际上有预警作用,在一定程度上对人有好处,A.与原文相符。B.过于绝对,是针对第4段第2句设的干扰项;C.与该段倒数第五句意思相反;D.与  该段最后一句意思相反。

  • A.you have to be in two places at once
  • B.the cells are subject to an excessive burden
  • C.the body is free from diseases
  • D.you are involved in too many activities
  • 解题思路:第3段第3和第4句提到,细胞负担过重,……结果就会出现疲劳。B.与原文意思相符.A.和D.是针对第3段第l句设的干扰项;文中第二种疲劳正是由疾病引起的,故C.与原文意思相反。
4.[单选题]Physical fatigue is usually caused by _________.
  • A.transmittable diseases
  • B.too many viruses
  • C.lack of physical exercise
  • D.excess wastes in the bloodstream
  • 解题思路:第2段提到,锻炼时体内会产生废料,而当血液中的废料达到一定量时,活动强度会下降,肌肉会疲劳并产生酸痛感,D.“血液中过量的废料”与原文意思相符。第3段第5句提到,一些传染病  会严重消耗人的能量,第6句提到,另一些非传染病也会如此,但这里所说的是由疾病引起的疲劳,与  题干的“身体疲劳”不符,故不选A.;B.未在文中提及;C.是针对第4段第4句设的干扰项。

  • B.Rest is the only solution for psychological fatigue.
