A scientific study in recent years has shown that it is a close relative of sadness and attention disorder; that procrastinators tend to be the result of low self-confidence and are likely to experience anxiety. The research has shown, what is more, that the illness has become quite common. Susan Robert, a behavioral psychologist who has written a book called Living With Procrastination, says that about a quarter of the adult population of the United States and Canada is reported to have serious problems with procrastination. “when we say ‘serious’we mean people for whom procrastination causes great discomfort and suffering. We’ve found that such people are more troubled by daily life than others, that possibility of anxiety is much higher among them than in the rest of the population.”In a society driven by achievement, it is little wonder that not being able to work at full steam will bring people sadness. Surely, in the land of opportunity, this anxiety has produced an industry of experts offering solutions. Many books and specialist solutions have appeared. In exchange for $ 19.95, Dr. Jerome Murray will send out an audio-cassette called “Protect yourfuture from the thief of procrastination.” Dr. Murray promises that if you follow his step-by-step rules you will be empowered to “turn self-defeat into self-realization”. “Since the start of the 1990s, procrastination has been taken more and more seriously,” said Dr. Roberts, who has been treating patients troubled by the condition for more than 20 years.” It is now recognized as a true mental health problem and is being seen more as a psychological problem and less as a moral issue.41．What is the main topic of this passage?A．Don’t hesitate to give up smoking.B．Don’t regard depression as not important.C．Delay can be a sign of illness.D．Don’t work too hard to stay healthy.正确答案：C42．Which statement is NOT true according to the passage?A．Procrastination is a disease of the mind.B．Procrastination is likely to cause a great discomfort and suffering.C．Procrastination is not considered as a psychological problem but moral issue.D．Dr. Jerome Murray provides some ways to get rid of procrastination.正确答案：C43．How does the author look at procrastination?A．It is something like running.B．It is a disease of mind.C．It is not a permitted act.D．It is not full of stress.正确答案：B44．These are the signs of procrastination except ( ).A．discomfortB．sufferingC．pleasureD．sadness正确答案：C45．What’s the main idea of Dr. Murray’s cassette “Protect your future from the thief of procrastination” ?A．Turn defeat to self-realization.B．Turn depression into enthusiasm.C．Procrastination has been taken more and more seriously.D．Turn self-defeat into self-realization.正确答案：DParrots are becoming one of the most popular pets in America for good reasons. The parrot is an extraordinary bird that can be taught to talk, can be easily cared for, and can create a lively atmosphere anywhere. With the help of an energetic parrot owner, a parrot can develop an enormous vocabulary. In addition, a parrot can be trained to say “Pretty boy” or “Polly wants a cracker, “and it also can learn to whistle or sing. No matter what an owner decides to teach a bird, training a parrot takes much patience, but the reward is a stream of chatter. Another reason for the parrot’s popularity is that this pet does not require much care. For example, even a spoiled parrot does not need a house-sitter for the purpose of daily walks and daily feeding. In fact, a parrot will overeat. Still another advantage of owning a parrot is its inexpensive food, including seeds, nuts, corn, and grain-along with an apple, banana, or carrot. Perhaps the most likely reason the parrot is becoming such a well-liked pet is that it is a combination of tameness and wildness. Because the parrot can live in almost any environment, it makes a fine, tame companion for many people. In addition, because it can be easily trained, it is a delightful performer. At the same time, its colorful feathers give it an air of the mystery of the parrot’s native home, the jungle. Thus, the parrot, once a highly valued gift presented to kings and noble families, is now appreciated by a growing number of people.46．A parrot can be trained to do all the following but ( ).A．talkB．help its ownerC．singD．create a lively atmosphere正确答案：B47．Which of the following is NOT a reason for the easy raising of the parrot?A．It eats very little.B．Its food is inexpensive.C．It does not need a house-sitter.D．It does not require daily walks as dogs do正确答案：A48．The word “tameness” in the passage means ( ).A．the quality of being brave or unafraidB．the quality of being kind or warm-heartedC．the quality of being uncontrolled or fierceD．the quality of being gentle or trained正确答案：D49．The word “jungle” probably means ( ).A．boundless desert with very little plant lifeB．large apartment building with pleasing surroundingsC．wild land overgrown with thick bushes and treesD．snow-covered mountain top in very cold areas正确答案：C50．The writer ( ).A．likes the parrotB．dislikes the parrotC．doesn’t care about the parrotD．values the parrot highly正确答案：AIn my long life I have seen many changes in our habits and customs and conditions in general. I think that you might be interested if I told you some of them. The world I entered at the age of eighteen when I became a medical student was a world that knew nothing of such advanced things as planes, films, radios or telephones. It was a very cheap world. Prices were stable. When I entered St. Thomas’hospital I rent a set of rooms in Vincent Square for which I paid 18 shillings a week. My landlady provided me with a very good breakfast before I went to the hospital and a dinner when T came back at half past six. I only had to pay for the breakfasts and dinners twelve shillings a week. For four-pence I lunched at St. Thomas’ on bread and butter and a glass of milk. I could be able to live very well, pay my fees, buy my necessary instruments, clothe myself, and have a lot of fun on fourteen pounds a month. And I could always pawn (当掉) my microscope for three pounds. I spent five years at St. Thomas’hospital. I was a bad student, for my heart, as you might have guessed, was not in it. I wanted, I had always wanted to be a writer, and in the evenings, after my dinner, I wrote and read. Before long, I wrote a novel called “Liza of Lambeth”, which I sent to a publisher and was accepted. It came out during my last year at the hospital and it was successful. It was of course an accident, but I didn’t know that. I felt I could afford to give up medicine and make writing my profession; so, three days after I graduated from the school of medicine, I left for Spain to write another book. I did not realize, at that time, that I was taking a great risk.51．The text is a talk given by the author when ( ) .A．he was 18B．his first novel was publishedC．he graduated from the school of medicineD．he was at an advanced age正确答案：D52．The author graduated from the school of medicine when he was ( ).A．18B．28C．23D．30正确答案：C53．“And I could always pawn my microscope for three pounds”means the author could always ( ) .A．exchange his microscope for three poundsB．borrow his microscope and pays three poundsC．have his microscope repaired with three poundsD．lend his microscope for three pounds正确答案：A54．In the sentence “I could be able to live very well, pay my fees, buy my necessary instruments, clothe myself...” , the word “clothe” means ( ).A．wear clothesB．make clothes forC．wash clothes forD．buy clothes for正确答案：D55．The author wanted to be a writer because ( ).A．he liked to take risksB．he found it easier to make a living by writingC．he was interested in writingD．he could not study medicine well正确答案：CHow often one hears children wishing they were grown-up, and old people wishing they were young again. Each age has its pleasures and its pains, and thehappiest person is the one who enjoys what each age gives him without wasting his time in useless regrets. Youth is a time when there are few tasks to make life difficult. If a child has good parents, he is fed, looked after and loved whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. In addition, life is always presenting new things to the children-things that have lost their interest for older people because they are too well-known. But a child has his pains: he is not so free to do what he wishes to do; he is continually being told not to do things, or being punished for what he has done wrong. When the young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way that he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he works hard, keeps out of trouble and has good health, he can have the great happiness of building up for himself his own position in society.56．People can experience happiness if they ( ).A．always think of the past and regret itB．value the presentC．are no longer youngD．become old and have much experience正确答案：B57．When people were young, they used to ( ).A．be in charge of many businessesB．have few things to think about and take onC．look after their younger sisters and brothersD．face a lot of difficulties正确答案：B58．The pains of children lie in the fact that ( ).A．no one helps them make right decisionsB．they are often beaten by their parentsC．they can not be accepted and praised by othersD．they are not allowed to do what they like to do正确答案：D59．Children are usually happy because ( ).A．old people lose interest in themB．they are free to do wrongC．they are familiar with everything going on around themD．things are new to them正确答案：D60．Which of the following is NOT needed for a young man to be happy?A．Hard workB．Being free from troubleC．WealthD．Health正确答案：CClozeMore than forty thousand readers told us what they looked for in close friendships, what they expected【C1】______friends, what they were willing to give in 【C2】______, and how satisfied they were【C3】______the quality of their friendships, the【C4】______give little comfort to social critics.

大学英语四级仔细阅读专项强化真题试卷8(题后含答案及解析)
大学英语四级仔细阅读专项强化真题试卷8(题后含答案及解析) 题型有：1.Aging happens to all of us, and is generally thought of as a natural part of life. It would seem silly to call such a thing a “disease.”On the other hand, scientists are increasingly learning that aging and biological age are two different things, and that the former is a key risk factor for conditions such as heart disease, cancer and many more. In that light, aging itself might be seen as something treatable, the way you would treat high blood pressure or a vitamin deficiency. Biophysicist Alex Zhavoronkov believes that aging should be considered a disease. He said that describing aging as a disease creates incentives to develop treatments. “It unties the hands of the pharmaceutical (制药的) industry so that they can begin treating the disease and not just the side effects,” he said. “Right now, people think of aging as natural and something you can’t control,” he said. “In academic circles, people take aging research as just an interest area where they can try to develop interventions. The medical community also takes aging for granted, and can do nothing about it except keep people within a certain health range. “But if aging were recognized as a disease, he said, “It would attract funding and change the way we do health care. What matters is understanding that aging is curable. ““It was always known that the body accumulates damage,” he added. “The only way to cure aging is to find ways to repair that damage. I think of it as preventive medicine for age-related conditions.”Leonard Hayflick, a professor at the University of California, San Francisco, said the idea that aging can be cured implies the human lifespan can be increased, which some researchers suggest is possible. Hayflick is not among them. “There’re many people who recover from cancer, stroke, or heart disease. But they continue to age, because aging is separate from their disease,” Hayflick said. “Even if those causes of death were eliminated, life expectancy would still not go much beyond 92 years.”1．What do people generally believe about aging?A．It should cause no alarm whatsoever.B．They just cannot do anything about it.C．It should be regarded as a kind of disease.D．They can delay it with advances in science.正确答案：B解析：推理判断题。

三、单项选择题（每小题1分，共20分）
1、简述人体代谢的供能系统。
答：人体运动中的能量供应可在两种供能形式下进行，即无氧代谢及有氧代谢，分别在这两种供能形式下工作的有三个供能系统。
（2分）
无氧代谢即指人体在供氧不足的状态下运动时，能量供应靠物质的无氧分解提供，主要由ATP—CP系统及糖酵解系统供能。
（2分）
人体在供氧充足的条件下运动时，能量供应由能源物质的彻底氧化供给，此时工作的供能系统为有氧氧化系统。
（2分）
2、肌纤维类型的分类？这种分类对体育运动实践有何意义。
答：肌纤维分为红肌（慢肌）和白肌（快肌），（1分）在快肌中可分为三个亚型：快红肌、快白肌和中间型。
（1分）由于不同的肌纤维类型在收缩性上的生理差异对不同的运动项目有直接的影响，（2分）红肌纤维比例较高者有利从事长时间运动的耐力项目，（1分）而白肌纤维比例较高者在短距离，高强度或爆发性力量的项目具有优势。
（1分）
3、运动性免疫抑制具有什么生理意义？
答：运动性免疫抑制现象从身体健康及维护机体安全角度而言，它具有非常重要的生理意义。
（1分）①运动过程中，免疫抑制现象作为对运动应激活动的反作用，使机体不能将全部能量和机能能力动员出来从事运动，以免反应程度过高过强，影响机体安全。
（1分）②运动过程中，免疫功能降低实质上是作为机体无法再继续工作的“信号”，提示机体应该适时“中止”运动。
（1分）③运动性免疫抑制程度与机体所完成的训练负荷直接相关。
训练负荷越大，运动后免疫抑制程度越深，抑制解除所需时间越长。
（1分）④若机体尚未恢复情况下继续坚持训练，机体利用免疫降低容易患病等提示机体已无法再坚持训练，强制性地要求机体休息、恢复，至少要求强制性地减量、减强度，以此保护机体安全。
（1分）⑤在运动后恢复期，免疫功能调控作用占优势，它可利用免疫降低强令机体休息促进恢复。
（1分）
4、根据儿童少年的神经系统特点，如何进行体育教学与训练？
答：儿童少年神经活动过程灵活性高但不稳定，活泼好动，注意力不易集中，（1分）动作不协调，易出现多余动作，分析和综合能力较低，条件反射建立得快，恢复也快。
（1分）儿童时期偏重第一信号系统，少年时期第二信号系统活动进一步发展，分析与综合能力逐渐提高。
（1分）
大脑皮质的神经细胞工作能力低，易疲劳，据此特点在教学中应注意：（1）多采用直观教学，形象、示范动作，精讲多练以及简单易懂的形象化语言、顺口溜、口诀等形式的教学方法。
（1分）（2）课的内容要生动活泼、多样，如游戏、小型比赛，并应多安排时间进行短暂休息。
（1分）（3）采用启发式教学，培养学生进行独立思考能力和分析综合能力，充分利用两个信号系统活动的能力和有目的地加强第二信号系统活动。
（1分）
六.论述题（共11分）
1、试述最大吸氧量的主要生理机制及其影响因素。
答：影响最大摄氧量的因素包括心脏的泵血功能和肌肉利用氧的能力。
（1分）心脏的泵血功能是影响最大摄氧量的中央机制，它取决于心脏容积和心肌收缩力。
（1分）在最大心率、每搏输出量不变的条件下，动静脉氧差是影响最大吸氧量的另一个重要因素。
（1分）它由肌肉利用氧的能力决定，是影响最大摄氧量的外周机制。
（1分）肌纤维类型也影响肌肉的摄氧能力，慢肌纤维由丰富的毛细血管分布，线粒体数目多、体积大，其酶的活性高，对氧的摄取能力也高；（1分）慢肌纤维肌红蛋白含量也比较高，有利于增加肌纤维的摄氧能力。
（1分）
此外，遗传也是影响最大摄氧量的因素之一。
年龄、种族、性别等因素与最大摄氧量有关。
（2分）
训练可以提高最大摄氧量，这是因为训练可增大心容积和心肌收缩力量。
（1分）训练可导致慢肌纤维线粒体增大、增多，线粒体氧化酶的活性增加，提高对氧的
摄取量。
（1分）同时，耐力训练在一定范围内可以导致快肌纤维的生理、生化代谢特征向慢肌纤维方向变化，提高摄氧和利用氧的能力。
（1分）。
