Psychosomatic illness is the occurrence of bodily symptoms(症状) which are psychological or emotional in origin.Mind and body are not separate; one affects and is affected by the other. Who has not experienced some physical manifestation of emotional stress? Such experiences as a headache after a quarrel and urinary frequency or diarrhea before an examination are not uncommon, and for most people they are of a temporary nature. The symptoms disappear and are forgotten after the crisis has passed. No treatment may beneeded, or the patient may use simple remedies to relieve the discomfort. One person may find that a leisurely walk is the best cure for a headache; another may take aspirin.Certain conditions have been considered classic examples of psychosomatic illness: pepticulcer, eczema, colitis, and asthma. Personality profiles have been developed to describe the typical characteristics of persons who develop such illness. Another point of view is that human beings are more complex and varied in their responses than such profiles would indicate, and that the type of illness a patient develops in relation to stress varies with many additional factors, such as heredity and environment. Much remains to be learned about the relationship between stress and physical illness.Physical symptoms, such as palpitation, sweating, or disturbance of sleep, which reflect anxiety, may occur over a prolonged period. The symptoms may seem mysterious and threatening, because the patient is unaware of their cause. The patient whose heart beats more rapidly and forcefully as a manifestation of anxiety may report this symptom to his doctor, believing that something is wrong with his heart. Often the patient is not aware that he is anxious. He knows only that his heart keeps pounding for no apparent reason.Almost any symptom can have its origin in emotional stress. Some patients almost invariably have the same stress when they become anxious. One may have diarrhea, another asthma, and a third may develop hives or eczema. Some people develop two or several different symptoms; often the symptoms are experienced in an alternating fashion.The development of bodily symptoms is only one manifestation of anxiety. It may show up also symptoms that areprimarily mental, such as the inability to concentrate or to remember. Such symptom too, vary in degree. Many people occasionally experience symptoms like moodiness or depression. When such symptoms are severe or long- lasting, they interfere with the functioning of individual in daily life and with his relationship with others.Sometimes a person subconsciously develops an illness as a way of handling a desperate need, such as the need for affection. The only real cure is to satisfy the primary desire. An example is a woman who has pain in her heart, not because of organic heart disease, but because the symptom is a way of gaining, if only temporarily, the love and attention for which she longs. Her husband cannot leave her when she is so sick; her children are concerned. Her pain is just as severe as if it had a physical cause.The reality of psychosomatic illnessIs the patient with psychosomatic illness really sick, or does he merely imagine he is sick? Many people, including the families of patients and members of the health professions, believe that physical illness which is influenced by emotional stress is less real, or wholly imaginary. Acknowledging the reality of the patients' illness is important; it is the first step in helping him.Patients with psychosomatic illness are likely to be neglected. The same staff who give excellent care to other patients, not uncommonly ignore them. Some possible reasons may include the use of the term psycho as a prefix. Perhaps this conveys the idea that such patients are mentally iii, and therefore have no physical illness. Perhaps they are considered weaklings. One hears comments like, "He could snap out(克服) of it if he wanted to." Prejudice against these patients may be due to a belief that they are pretending illness in an attempt to get attention orfavors.A patient with psychosomatic illness may be confused with a malingerer, one who deliberately pretends illness in order to achieve secondary gain, such as financial compensation or excuse from work. Pretending illness is considered an unhealthy and unsatisfactory solution to the problems of life. Often it adds to the patient's difficulties, as he makes elaborate attempts to avoid detection. A malingerer can be helped sometimes to find ways of coping with difficulties. The essential difference between psychosomatic illness and malingering is that the malingerer pretends symptoms. It is a conscious process and he is aware that he is pretending to be sick. The patient with psychosomatic illness develops symptoms as manifestation of largely unconscious psychic conflicts. The symptoms are real.Condemnation(责难) of the patient with psychosomatic illness can persist despite intellectual understanding of theories about its cause. The patient can sense immediately whether those who care for him are trying to help him or not. It is important to understand that:·The patient with psychosomatic illness is really sick. He is not pretending or imagining his symptoms.·The idea that he can "snap out of it" at will is no more true than it is of those with diseases like pneumonia, whose need for care is readily acknowledged.1. The symptoms of some people with psychosomatic illness are experienced in an alternating fashion.2. Moodiness and depression are symptoms that don't last long.3. Psychosomatic sick people will stop cheating when they sense that those who care for them are belittling them.4. People with psychosomatic illness tend to be given less care than they deserve.5. Malingerers are those who pretend to be iii for some other purposes.6. The symptoms of people with psychosomatic illness are primarily mental.7. Today more and more people are suffering from psychosomatic illness.8. Such conditions as ___________ have been considered classic examples of psychosomatic illness.9. Psychosomatic symptoms may be primarily mental, such as the inability ______.10. The first and the most important step in helping the psychosomatic patients is to ______.试题详解1.Y 由题干中的关键词alternating fashion定位到第一个小标题下面第五段末句: Some people develop two or several different symptoms;often the symptoms are experienced in an alternating fashion,题目是原文的同义替换,由此得出题目说法正确。

英语四级CET4阅读练习题及答案

英语四级CET4阅读练习题及答案英语四级CET4精选阅读练习题及答案在当今这个学习英语风潮盛行的社会,英语似乎已经成为了我们生活中不可或缺的一部分,下面是小编为大家搜索整理的英语四级辅导练习,希望能给大家带来帮助!Henry III didn't know much about biology. He went through six wives back in the 1500s, looking for one whocould bear him a son. Scientists now know that it's the father's sperm, not the mother's egg, which determines whether a baby is a boy or a girl. And last week researchers at the Genetics and IVF Institute, a private fertility(生育能力)center in Virginia, announced a new technique that will allow parents to choose the sex of their baby-to-be, before it has even been conceived. The scientist used a tiny laser detector to measure the DNA in millions of sperm cells as they pass single file through a narrow tube, like cattle being herded through a corral(牲口栏). In a study published last week, "girl sperm," which has more DNA—the genetic material—in each cell, was collected, while "boy sperm" was discarded. And when purified girl sperm was used to impregnate(使受孕)a group of mothers, 15 of 17 resulting babies turned out to be girls.The researchers say that "sex selection" can also double a mother's chance of having a son and can be usedto avoid genetic diseases that affect only one gender, such as hemophilia(血友病). But some experts, like New York University fertility specialist Dr. Jamie Grifo, worry that sex selection could lead to a kind ofin uteri(子宫)discrimination, especially in cultures where sons are considered superior to daughters. "It's valuing one gender' over another," Grifo says. "I don't think that's something we should be doing." So far, patients at the institute have been asking for bothboys and girls, in order to "balance" their families. And some ethics experts say that's fine, as long as parents are just looking for a little gender variety. "If you have three boys, and you want a girl," says University of Texas reproductive-law professor John Robertson, "that's not gender bias at all."练习题:Choose correct answers to the question:1.The DNA in the sperm cells can be measured ______.A.in the same way how the cattle are herdedB.when they pass through a tube one behind the otherC.after they pass through a laser tubeD.when they are scanned by a laser detector all at a time2.The gender of the baby is decided by ______.A.the father's DNAB.the mother's DNAC.the father's spermD.the mother's egg3.According to this passage, the practice of "sex selection" ______.A.can help to prevent all genetic problemsB.is totally unacceptable to ethics expertsC.was already realized five hundred years agoD.will benefit families with certain inheritable diseases4.Girl sperm was preferred to boy sperm in the research most probably because____A.girl sperm contains more genetic materialB.more mother want to have girl babiesC.girl sperm is healthier and more activeD.girl sperm is more easily purified5.It can be concluded from the passage that author’stoward”sex selection”is____A.negativeB.positiveC.neutralD.favorable参考答案1.[B] 推理判断题。

They have opened the eyes of students in underdeveloped regions to the outside world by bringing them new knowledge and thoughts. As a result, they are extremely well—received by the children there. On the other hand, college students have received a rigorous training by adapting to the harsh living conditions. They are enjoying the appreciation and no—distance friendship from the children.

Why does this craze appear?There are mainly two reasons behind this phenomenon. First, it is the employment pressure that forces college students to get more certificates. With the admission expansion of colleges, a lot more graduates have to face the fierce competition in the job market. How can one makehimself more competitive? More certificates at hand, maybe. Second, diploma and certificates are still important standards by which many employers measure a person’s ability. In order to increase the qualifications for a job, the students compel themselves to run from one exam to another。

Passage OneQuestions 21 to 25 are based on the following passage:The view over a valley of a tiny village with thatched(草盖的)roof cottages around a church; a drive through a narrow village street lines with thatched cottages painted pink or white; the sight in parts of England. Most people will agree that the thatched roof is an essential part of the attraction of the English countryside.Thatching is in fact the oldest of all the building crafts practiced in the British Isles(英论诸岛). Although thatch has always been used for cottage and farm buildings, it was once used for castles and churches, too.Thatching is a solitary(独自的)craft, which often runs in families. The craft of thatching as it is practiced toady has changed very little since the Middle Ages. Over 800 full-time thatchers are employed in England and Wales today, maintaining and renewing the old roofs as well as thatching newer houses. Many property owners choose thatch not only for its beauty but because they know it will keep them cool in summer and warm in winter.In fact, if we look at developing countries, over half the world lives under thatch, but they all do it in different ways. People in developing countries are often reluctant to go back to traditional materials and would prefer modern buildings. However, they may lack the money to allow them to import the necessary materials. Their temporary mud huts with thatched roofs of wild grasses often only last six months. Thatch which has been done the British way lasts from twenty to sixty years, and is an effective defiance against the heat.C21.Which of the following remains a unique feature of the English countryside?A) Narrow streets lined with pink or white houses.B) Rolling hills with pretty farm buildings.C) Cottages with thatched roofs.D) churches with cottages around them.D22.What do we know about thatching as a craft?A) It is a collective activity.B) It is practised on farms all over England.C) It is quite different from what it used to be.D) It is in most cases handed down among family members.A23.Thatched houses are still preferred because of _________.A) their style and comfortB) their durabilityC) their easy maintenanceD) their cheap and ready-made materialsB24.People in developing countries also live under thatch because ________.A) thatched cottages are a big tourist attractionB) thatched roof houses are the cheapestC) thatch is an effective defense against the heatD) they like thatched houses better than other buildingsA25.We can learn from the passage that _________.A) thatched cottages in England have been passed down from ancient timesB) thatching is a building craft first created by the English peopleC) the English people have a special liking for thatched housesD) most thatched cottages in England are located on hillsides答案:CDABAPassage TwoQuestions 26 to 30 are based on the following passage:President Coolidge’s statement, “The business of America is business,”still points to an important truth today-that business institutions have more prestige(威望)in American society than any other kind of organization, including the government. Why do business institutions posses this great prestige?One reason is that Americans view business as being more firmly based on the ideal of competition than other institutions in society. Since competition is seen as the major source of progress and prosperity by most Americans, competitive business institutions are respected. Competition is not only good in itself, it is the means by which other basic American values such as individual freedom, equality of opportunity, and hard work are protected.Competition protects the freedom of the individual by ensuring that there is no monopoly(垄断)of power. In contrast to one, all-powerful government, many businesses compete against each other for profits. Theoretically, if one business tries to take unfair advantage of its customers, it will lose to competing business which treats its customers more fairly. Where many business es compete for the customers’ dollar, they cannot afford to treat them like inferiors or slaves.A contrast is often made between business, which is competitive, and government, which is a monopoly. Because business is competitive, many Americans believe that it is more supportive of freedom than government, even though government leaders are elected by the people and business leaders are not. Many Americans believe, then, that competition is as important, or even more important, that democracy in preserving freedom.Competition in business is also believed to strengthen the ideal of equality of opportunity. Competition is seen as an open and fair race where success goes to the swiftest person regardless of his or her social class background. Competitive success is commonly seen as the American alternative to social rank based on family background. Business is therefore viewed as an expression of the idea of equality of opportunity rather than the aristocratic(贵族的)idea of inherited privilege.26.The stat ement “The business of America is business” probably means “________”.A) The business institutions in America are concerned with commerceB) Business problems are of great importance to the American governmentC) Business is of primary concern to AmericansD) America is a great power in world business27.Americans believe that they can realize their personal values only ________.A) when given equality of opportunityB) through doing businessC) by protecting their individual freedomD) by way of competition28.Who can benefit from business competition?A) Honest businessmen.B) Both businessmen and their customers.C) People with ideals of equality and freedom.D) Both business institutions and government.ernment is believed to differ strikingly from business in that government is characterized by ________.A) its absolute control of powerB) its function in preserving personal freedomC) its role in protecting basic American valuesD) its democratic way of exercising leadership30.It can be inferred from the passage that the author believes _________.A) Americans are more ambitious than people in other countriesB) in many countries success often depends on one’s social statusC) American businesses are more democratic than those in other countriesD) businesses in other countries are not as competitive as those in America翻译:柯立芝总统说,“美国的事业就是工商业”,今天这句话仍然指出了一个很重要的真理:工商业机构在美国社会比任何其他组织,包括美国政府,威望更高。

Unit 4 补充题1 补充题1
(Para 1) There are hidden factors which scientists call “feedback mechanisms”. No one knows quite how they will interact with the changing climate. Here's one example: plants and animals adapt to climate change over centuries. At the current estimate of half a degree centigrade of warming per decade, vegetation(植物) may not keep vegetation(植物 植物) up.
Climatologist James Hansen predicts climate zones will shift toward the poles by 50 to 75kilometres a year- faster than trees yearcan naturally migrate. Species that find themselves in an unfamiliar environment will die. The 1000 kilometre-wide strip of forest kilometrerunning through Canada, the USSR and Scandinavia could be cut by half. Millions of dying trees would soon lead to massive forest fires, releasing ions of CO2 and further boosting global warming.
4. It can be inferred from the passage that ________. A. the developing world has decided to increase its energy consumption B. a third-world citizen adds less than a ton thirdof CO2 yearly to the atmosphere C. the world climate would soon gain its balance if we stopped greenhouse gas emissions D. future prosperity of the world is dependent on cheap fossil fuels
3. We can learn from the passage that ________. A. some feedback mechanisms may slow down global warming B. the basic facts of global warming are unknown C. developing countries benefit from cheap fossil fuels D. developed countries have decided to reduce their energy consumption
(Para 2) There are dozens of other possible “feedback mechanisms”. Higher temperatures will fuel condensation and increase cloudiness, which may actually damp down global warming.
1. “Feedback mechanisms” in paragraph 1 most probably refer to ________. A. how plants and animals adapt to hidden factors B. how plants and animals interact with the changing climate C. how climate changes D. how climate zones shift
(Para 4) Material progress has been linked to energy consumption. Today 75 per cent of all the world's energy is consumed by a quarter of the world's population. The average rich world resident adds about 3.2 tons of CO2 yearly to the atmosphere, more than four times the level added by each Third World citizen. The US, with just seven per cent of the global population, is responsible for 22 per cent of global warming.
4. It can be inferred from the passage that ________. A. the developing world has decided to increase its energy consumption B. a third-world citizen adds less than a ton thirdof CO2 yearly to the atmosphere C. the world climate would soon gain its balance if we stopped greenhouse gas emissions D. future prosperity of the world is dependent on cheap fossil fuels
3. We can learn from the passage that ________. A. some feedback mechanisms may slow down global warming B. the basic facts of global warming are unknown C. developing countries benefit from cheap fossil fuels D. developed countries have decided to reduce their energy consumption
5. Which of the following is the main topic of the passage? A. Material progress and energy consumption. B. Prosperity and cheap fossil fuels. C. Impact of global warming on climate. D. Plants and animals in the changing climate.
2. James Hansen predicts that the shift of climate zones will be accompanied by ________. A. the cutting of many trees. B. desirable environmental changes. C. successful migration of species. D. unsuccessful migration of trees.
