职称英语考试《综合类》每日一练精选及答案0524-1391、Woman workThough some people have suggested that women should return to housework in order to leave more jobs for men, the idea has been rejected by both women and men in public opinion polls. Lately some union officials have suggested that too many women are employed in types of work more suitable for men and that women should step aside to make way for unemployed young men. They argue that women, especially women in their childbearing years,actually delay economic development and result in productivity, poor quality and inefficiency.To solve the problem, they suggested that working women stay at home while their husbands or brothers were given double wages. They argue that under these circumstances, families would remain their same level of income, and women could run the house and raise children much better,The suggestion, however , has been flatly rejected by 9 0ut of10 people polled .Some other people have suggested another way called "phased employment" theory. The theory suggests that a woman worker take leave from her job when she is seven months pregnant and stay off the job until her baby reaches the age of 3. It suggested that women on leave receive 75 percent of their normal salary and be allowed to return to work after the three-year period. This will ____ children, women, their families and the society and it definitely seems to be more acceptable than the suggestion that women return to their homes forever.【单选题】A.profitB.interestC.serveD.benefit正确答案:D答案解析:benefit:对……有好处；profit、interest是名词，不能用在这里。

3、LanguageWhen one looks back upon the fifteen hundred years that arethe life span of the English language, he should be able to notice a number of significant truths. The history of language is a history of constant change-at times a slow, almost imperceptible change, at other times a violent collision between two languages. Language a living growing organism, it has never been static. Another significant truth that emerges from such a study is that language at all times has been the possession not of one class or group but of many. At one extreme it has been the property of the common, ignorant folk, who have used it in the daily business of their living, much as they have used their animals or the kitchen pots and pans. At the other extreme it has been the treasure of those who have respected it as an instrument and a sign of civilization, and who have struggled by writing it down to give it some permanence, order, dignity, and if possible, a little beauty.As we consider our changing language, we should note here two developments that are of special and immediate importance to us. One is that since the time of the Anglo-Saxons there has been an almost complete reversal of the different relationship of words in a sentence. Anglo-Saxon(old English) was a language of many inflections. Modern English has few inflections. We must now depend largely on word order and function words to convey the。

职称英语考试《综合类》每日一练精选及答案0524-1511、RobotsThe most sophisticated (先进的) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接), spray-painting and assembling components.In Britain robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.It has been calculated that a robot uses on average about 100times more energy than a human to do an equivalent job.It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan.The reliability of robots is measured in their MTBF or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small .sample.The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. One programmed robots can work more accurately and consistently than humans, who can get tired and bored.Paragraph 5 ________.【单选题】A.Ongoing ResearchB.Extension of UseC.Robot HeroesD.Greater ReliabilityE.Falling DemandF.Hidden Danger正确答案:C答案解析:第五段共两句话，其中主题句是第一句：It is estimated that 20% of all comic book heroes in Japan are robots.（据估计，日本20%的漫画书的主人公是机器人。

职称英语考试《综合类》每日一练精选及答案0524-1001、An Early Form of Jazz MusicMusic comes in many forms; most countries have a style of their own. At the turn of the last century, when jazz was born, America had no prominent music 0f its own. No one knows exactly when was invented or by whom. But it began to be heard in the early 1890s. Jazz is America's contribution to popular music. In contrast to classical music, which ____ formal European traditions, jazz is spontaneous and free in form. It bubbles with energy, expressing the moods, interests, and emotions of the people. In the 1920s' jazz sounded like America. And so it does today. The origins 0f the music are as interesting as the music itself. American Negroes, or blacks, as they are called today, were the jazz pioneers. They were brought to the Southern states as slaves. They were sold to plantation owners and forced to work long hours. When a Negro died, his friends and relatives formed a procession to carry to body to the cemetery. In New Orleans, a band often accompanied the body . On the way to the cemetery the band played slow, solemnmusic, suited to the occasion. Furthermore 0n the way home the mood changed. Spirits lifted. Death had removed one of their numbers, but the living were glad to be alive . The band played happy music, improvising on both the harmony and the melody of the tunes played at the funeral. This music made everyone want to dance. It was an early form ofjazz.【单选题】A.introducesB.followsC.takesD.approaches正确答案:B答案解析:古典音乐发端于欧洲，所以它遵循的是欧洲传统。

职称英语考试《综合类》每日一练精选及答案0524-471、Gun Rights in the USImmediately after the shooting at Virginia Tech University, Americans gathered to mourn (致哀) the dead. The president and the state governer both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons.Strictly speaking, the US is not the only country here gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the few countries that seem unwilling and politically incapable of doing anything serious to stop it.In countries like Britain and Canada, the government adopted strict gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby (院外活动集团) and the electoral (选举) system.The powerful National Rifle Association, the major supporter of gun ____ in the US, is too strong for any party to take on. MostRepublicans oppose gun control anyway. Over the years, the Democrats have found that they can either campaign for gun control or win power, not both, they prefer power.According to the US Bureau of Justice Statistics, firearm (火器) incidents accounted for nine percent of the 4.7 million violent crimes in 2005. So although opinion polls show most Americans want stricter gun laws, many people don't want to give up their arms they keep to protect themselves.Dave Hancock, a Virginia gun lover, is one example. In an interview he said, "If one professor in the Virginia incident had been carrying a legal weapon, they might have been able to stop all this. "In his opinion, the massacre (大屠杀) is an argument for more people to carry weapons, not fewer. Americans' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government, commented UK's Guardian newspaper.One Virginia resident, who had a permit to carry a concealed (隐藏的) firearm, told the Guardian that it was every American's responsibility to have a gun."Each person," he said, "should not rely solely on the government for protection."【单选题】A.fireB.attacksC.violenceD.rights正确答案:D答案解析:本题有一定难度，根据文章句意，此处是指“持枪权利”，gun rights，所以最佳答案是D。

职称英语考试《综合类》每日一练精选及答案0524-1291、A Country's Standard of LivingThe "standard of living" of any country means the average person's share of the goods and services the country produces.A country's standard of living, therefore, depends first on its capacity to produce wealth. "Wealth" in this sense is not money, for we do not live on money but on things that money can buy: "goods such as food and clothing", and "services" such as transport and entertainment.A country's capacity to produce wealth depends upon many factors most of which have an effect on one another. Wealth depends to a great extent upon a country's natural resources. Some region of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate, other regions possess none of them.Next to natural resources comes the ability to turn them to use, China is perhaps as rich as the USA in natural resources, but suffered for many years from civil and external wars, For thisand other reasons it was unable to develop her resources. Sound and stable political conditions, and freedom from foreign invasions, enable a country to develop its natural resources peacefully and steadily, to produce more wealth than other country.A country's standard of living does not only depend upon the wealth that is produced and consumed within its own borders, but also upon what is directly produced through international trade. For example, Britain's wealth in foodstuffs and other agricultural products would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus (剩余的) manufactured goods to be traded abroad for the agricultural products ____ would otherwise be lacking. A country's wealth is, therefore, much influenced by its manufacturing capacity, providing that other countries can be found ready to accept its manufactures.【单选题】A.whoB.whichC.whereD.when正确答案:B答案解析:本题有一定难度，干扰项干扰较大，本题考查引导非限制性定语从句的关系词，先行词是products，所以正确答案是B。

职称英语考试《综合类》每日一练精选及答案0524-351、Migrant (移民的) WorkersIn the past twenty years, there has been an increasing tendency for workers to move from one country to another. While some countries have restricted most jobs to local people, others have attracted and welcomed migrant workers. This is particularly the case in the Middle East, where increased oil incomes have enabled many countries to call in outsiders to improve local facilities. Thus the Middle East has attracted oil workers from the USA and Europe. It has brought in workers from many countries, ______ South Korea and Japan.In view of the difficult living and working conditions in the Middle East, it is not surprising that the pay is high to attract suitable workers. Many engineers and technicians can earn at least twice as much money in the Middle East as they can in their own country, and this is a major attraction .Sometimes a disadvantage has a compensating (补偿的) advantage. For example, the difficult living conditions oftenlead to increased friendship when workers have to depend on each other for safety and comfort. In a similar way, many migrant workers can save large sums of money partly because of the lack of entertainment facilities. The work is often complex and full of problems but this merely presents challenge to engineers who prefer to find solutions to problems rather than do routine work in their home country.One major problem which affects migrant workers in the Middle East is that their jobs are temporary ones. They are nearly always on contract, so it is not easy for them to plan ahead with great confidence. This is to be expected since no country welcomes a large number of foreign workers as permanent residents. In any case, migrant workers accept this disadvantage, along with others, because of the considerable financial benefits which they receive.【单选题】A.opposingB.limitingC.includingD.asking正确答案:C答案解析:很显然，整个句子的意思是：中东引进了包括韩国和日本在内的许多国家的工人。

职称英语考试《综合类》每日一练精选及答案0524-1301、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃which _____ in Antarctica in 1983.We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃to -120℃. The temperature depends upon whether you are in direct sunlight or shade, Obviously, -120℃is colder than our body can safely endure. Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowestestimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.Why is the two scientists' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein's calculations helped him theorize would behave as Bose thought but only at very cold temperatures. Scientists have also discovered that ultra-cold atoms can help them make the world's atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】A.openedB.occurredC.opposed'D.operated正确答案:B答案解析:本段叙述地球上记录到的最低温度是-91℃，本段最后一句的后半句显然是交代这一最低温度是在南极洲出现的，所以occurred（发生、出现）是正确的选择。

职称英语考试《综合类》每日一练精选及答案0524-1361、Continuing Education1 People around the world agree that education is not an end, but a means to an end. In other words, we do not educate students only for the aim of educating them. Our purpose is to fit them for life. Life is varied; so is education.2 Ideas about education are more specified in the United States. Education today is not just a high school diploma or a college degree. Many adults are not interested in going to college. They are interested in other kinds of learning. For them, learning does not end with a diploma.3 Continuing education gives these adults the opportunity to increase their knowledge about their own field or to learn about a new field. It also gives them a chance to improve their old skills or to learn new ones. Scientists, mechanics, secretaries, barbers and cooks can take classes to improve their work skills. If they know more or learn more, they can get a better job or earn more money.4 Continuing education classes give more adults the chance to learn new skills. There is usually a large variety of classes to choose from: typing, foreign cooking, photography, auto repair, furniture repair, or swimming. There are only some of the classes available.5 Some adults take classes for fun or because the class will be useful for them. Other adults take continuing education classes to improve their own lives because they want to feel better about themselves.6 Almost any community college or public school system has a continuing education program. There are classes in schools, community buildings or churches. Most classes are in the evenings, so working people can attend. The classes are usually small, and they are inexpensive.The best title for the passage would be ____【单选题】A.adults should go on learning after graduating from schoolB.to enlarge their knowledge and learn new skillsC.by community colleges and public schoolsD.only for working peopleE.Continuing Education ClassesF.The Importance of a College Degree正确答案:E答案解析:文章先提了全世界人民对教育的看法，接下来讲了美国人对教育的理解。

职称英语考试《综合类》每日一练精选及答案0524-1371、A Strong Greenhouse Gas1 Methane is a colorless, odorless gas; it is also a potent greenhouse gas, and once released into the atmospheres, it absorbs beat radiating from Earth's surface. That's why methane is a major contributor to the planet's increasing temperature rise or global warming. Molecule for molecule, methane's heat-trapping power in the atmosphere is 21 times stronger than carbon dioxide, the most abundant greenhouse gas.2 With 13 billion cows belching almost constantly around the world (100 million in the U. S. alone), it's no surprise that menace released by livestock is one of the chief sources of the gas. Other prime methane sources: petroleum, drilling, coal mining, solid-waste landfills and wetlands.3 Greenhouse gases like methane and carbon dioxide make up only a small part of Earth's atmosphere, which is 78 percent nitrogen and nearly 21 percent oxygen. And without greenhouse gases to trap the sun's heat and warm the planet,life as we know it couldn't exist. But in the last200 years, human activity that requires burning oil, natural gas, and coal for energy has magnified the greenhouse effect.4 Atmospheric concentrations of methane have more than doubled in the last two centuries. Blame for this often focuses on big industries and gas-guzzling vehicles. But agriculture plays a major role, too. In the past 40 years alone, the global cattle population has doubled.5 Cows munch mostly grasses and hay yet they grow big and hefty. Why? Because of the rumen. The rumen holds 160 liters of food and billions of microbes. These microscopic bacteria and protozoa break down cellulose and Fiber into digestible nutrients. A cow couldn't live without its microbes. As the microbes digest cellulose, trey release methane. The process occurs in all animals with a rumen (cows, sheep, and goats, for example), and it makes them very gassy. It's part of their normal digestion process. When they drew their cud, they regurgitate some food to rechew it, and all this gas comes out. The average cow expels 600 liters of methane a day.That's why we say livestock gas is also a major factor of causing the global warming.Paragraph l ____【单选题】A.Life of Macroscopic Bacteria in Livestock's RumenB.Ways to Reduce Methane's Heat-trapping PowerC.Agriculture Also Contributes to Increased Concentrations of Methane in the AtmosphereD.Why Livestock Releases MethaneE.Methane as a Strong Greenhouse GasF.Livestock as a Prime Factor of the Greenhouse Effect正确答案:E答案解析:本段的第3句点出了“methane's heat-trapping power in the atmosphere is 21 times stronger than carbondioxide. ”2、The State of Marriage TodayIs there something seriously wrong with marriage today? During the past 50 years, the rate of divorce in the United States has exploded: almost 50% of marriages end in divorce now, and the evidence suggests it is going to get worse. If this trend continues, it will lead to the breakup of the family, according to a spokesperson for the National Family Association. Some futurists predict that in 100 years, the average American will marry at least four times and extramarital affairs will be even more common than they are now.But what are the reasons for this, and is the picture really so gloomy? The answer to the first question is really quite simple: marriage is no longer the necessity it once was. The institution of marriage has been based for years partly on economic need. Women used to be economically dependent on their husbands as they usually didn't have jobs outside the home. But with the rising number of women in well-paying jobs, this is no longer the case, so they don't feel that they need to stay in a failing marriage.In answer to the second question, the outlook may not be aspessimistic as it seems. While the rate of divorce has risen, the rate of couples marrying has never actually fallen very much, so marriage is still quite popular. In addition to this, many couples now cohabit and don't bother to marry. These couples are effectively married, but they do not appear in either the marriage or divorce statistics. In fact, more than 50% of first marriages survive. The statistics are deceptive because there is a higher number of divorces in second and third marriages than in first marriages.So is marriage really an outdated institution? The fact that most people still get married indicates that it isn't. And it is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences, such as heart problems, and married men generally consider themselves more contented than their single counterparts. Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!Which is true about the problem of marriage in the United States today?【单选题】A.Divorce leads to the breakup of the family.B.Half of the married couples get divorced.C.American people marry more than four times.D.More and more people are getting divorced.正确答案:D答案解析:从第1段里可以了解到选项A与C都是预计将来会发生的，而不是如今的情况。

2、Human Space ExplorationWhile scientists are searching the cause of the Columbia disaster, NASA is moving ahead with plans to develop a new craft that would replace shuttles(航天飞机) on space station missions by2012 and respond quickly to space station emergencies.The space agency released the first set of mission needs and requirements several days ago for me orbital space plane (轨道航天飞机), which would be designed to transport a crew of four to and from the International Space Station.Although it includes few specifics, the plan states the orbiter(轨道航天飞机) will be safer cheaper and require less preparation time than the shuttle. It would be able to transport four crew members by 2012 though it would be available for rescue missions by 2010. NASA says the craft should be able to transport injured or ill space station crew members to"definitive(决定性的) medical care" within 24 hours.The release of the requirements showed NASA remains focused on the long-term priorities of space exploration, even as questions exist concerning the loss of Columbia and its seven member crew on February l, 2003.Expels at Marshall Space Flight Center in Huntsville, Alabama, have been working for years on a successor to the shuttle. The project, known as the Space Launch Initiative (倡议), was divided last year into two parts----one focusing on a future launch vehicle, the other on a space station orbiter. The orbiter is expected to be ready sooner.The program's managers say NASA officials have told them not to alter Space Launch Initiative in light of the Columbia disaster. U. S. President George W. Bush asked Congress for about US$1 billion for Space Launch Initiative in 2004, funds that would be almost equally split between the Orbital Space Plane and Next Generation Launch Technology.When did NASA start working on a successor to the shuttle?【单选题】。

职称英语考试《综合类》每日一练精选及答案0524-1321、Ceasing to Wear TiesIt's useless. It's dirty. It spreads disease. That's why the British Medical Association in the UK recently called for hospital doctors to stop wearing ties.That leads to another question. Why does anyone wear a tie? Ties serve no purpose. They do not cover any part of your body and keep you warm. They always seem to get covered in food stains. Perhaps that is the purpose of the tie. It lets everyone know what you just ate.Ties have an odd history. Soldiers from Croatia, in Eastern Europe, served as mercenaries (雇佣军) in various conflicts in the 17th century. They were identified by brightly colored pieces of silk worn around the neck. Known as cravats(围巾), these became a popular fashion item in France and eventually evolved into the tie.It's an interesting story, but it doesn't tell us why men want to put useless pieces of cloth or silk around their necks. Theanswer seems to be about identification(身份证明). In the 19th-century Britain, ties were used by universities, military regiments (团), sports clubs, schools and gentleman's clubs. Each tie was in a particular set of colors which identified the wearer as a member of that organization. Wearing ties was also the mark of Britain's most powerful classes. That made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger class-the business class.You cannot wear a tie if you work with machinery, so wearing a tie became a sign that you were a man who used his brain to make a living, rather than his hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who did not wear a piece of colored silk around his neck. This is how millions of people came to wear ties across the world.Is there a future for ties? The signs are not promising. Many political leaders, including British Prime Minister Tony Blair, now go without ties.Paragraph 3 ________.【单选题】A.Origin of the tieB.British tieselessness of the tieD.Old-fashioned tiesE.Role of the tieF.Signs of a tieless era正确答案:A答案解析:第三段的主题句是第一句Ties have an odd history （领带的历史比较奇怪）。

职称英语考试《综合类》每日一练精选及答案0524-1551、Status of Teachers in AmericaAt present, in many American cities especially, many teachers in the public schools say they are underpaid. They point to jobs such as secretary or truck driver, which often pay more to start than that of the teacher. In many other fields, such as law, medicine, computer science, a beginning worker may make more than a teacher who has taught for several year. Teaching has never been a profession that attracted people interested in high salaries. It is by history a profession that has provided rewards in addition to money, the satisfaction of sharing knowledge, of influencing others, of guiding young people. But in the past several years, there are more difficulties in teaching, for many, than there are rewards.Unruly students, who would have chosen teaching as their life career in the past, are going into other fields.Another reason for this change in teacher candidates is the changing status of women in the United States. Until the late1960s and 1970s, one of the most popular choices for women was teaching. But as other professions, such as law and medicine opened up to women, women stopped pouring into teacher training programs. Thus, a major pool of excellent candidates for the teaching profession dwindled(减少).Bit by bit government officials and others realized that the status of the teacher had suffered. They talked about change. But change in a vast society like the United States is not easy. People's attitudes have formed over many years, and sometimes change takes many years.The writer points out the present situation of teaching, that is_____.【单选题】A.teaching is a profession that can always attract best students to work in.B.teaching can provide rewards as well as high salaries.C.teachers work hard and make a small income compared to workers in many other jobs.D.teachers are no longer underpaid.正确答案:C答案解析:A选项的说法和第2段第1句矛盾；B选项和第2段最后一句矛盾；D选项和第1段第1句矛盾，因此C是正确的。
