剑桥雅思9 口语 Test3 参考答案
答案编辑者：上海环球雅思口语名师：李宁（英国剑桥国际考试委员会IGCSE & A Level口语考官）微博：环球雅思李宁Part 1The examiner asks the candidates about him/herself, his/her home, work or studies and other familiar topics.EXAMPLETelephoningHow often do you make telephone calls?[ why/ why not?]Although I generally send emails and text messages, I still make telephone calls on a daily basis. I regularly need to call my colleagues, especially if its urgent or complicated, so its more convenient than sending text messages. However, I also make social phone calls to my friends and family, just to chat and see how their day has been!Who do you spend most time talking to on the telephone?[why]It changes, day to day. I probably make most phone calls to my colleague, Maria, especially as we are also friends outside of work. Sometimes I will call her to ask her a question about work, but I will also call her if I am going shopping to see if she wants anythings from the shops, to see if she wants to come over dinner, or would like to go for a bike ride! I always call my parents twice a week, on Wednesday and Saturday evenings. If I don't call then they will get worried!When do you think you’ll next make a phone call?[why?]I will call my American friend, Jesse, as soon as I finish work to ask him if I can borrow his big cooking pot. I have invited some friends to dinner at my apartment tomorrow evening, and I am planning to cook a big stew, so I will need to borrow his pot.Do you sometimes prefer to send a text message instead of telephoning? [why/ why not?]Yes certainly. I think sending text messages is often more convenient. For example, if I am on a bus or train where its too noisy, or if I am eating in a restaurant where I do not want to annoy other diners, then I will always send a text message. People often send me a text message, because they know I am teaching during the daytime and I cannot answer my phone. So instead, they send me a text message and I will reply as soon as I am free.Part 2Describe a journey [e.g. By car, plane, boat] that you remember well.You should say:Where you wentHow you traveledWhy you went on the journeyand explain why you remember this journey wellYou will have to talk about this topic for one to two minutes.You have one minute to think about what you are going to say.You can make some notes to help you if you wish.In the summer of 2010, I cycled coast-to-coast across the United States of America with two of my best friends from University.The three of us met at university in Liverpool, and we shared an interest in cycling. We regularly went on biking and camping trips into the Lake District at weekends if we had free time. During our final year, we decided it would be a great idea to train up and attempt to cycle across the North American continent to raise money for charity.So in July 2010, after months of training and preparation, we flew across the Atlantic Ocean to begin the 7,000 km journey across the USA.The journey was far more challenging than we thought it would be. Both our mental and physical limits were put to the test as we cycled across mountains, deserts and rivers, sometimes going days without seeing any other people. We had to carry a lot of heavy equipment on our bikes, and we camped almost every night. If we were passing through a large town then we would stay in a hotel, to get a good night sleep and to have a shower! But more often than not, we would camp in the wild and wash in rivers and waterfalls.Our journey began in Maryland and took us west, through the country's capital city, Washington DC, over the Appalachian mountains and the Mississippi River onto the Kansas plains. From there we continued west over the Rocky Mountains and the deserts of Utah and Nevada. Finally, we crossed the Sierra Nevada mountain range and descended through California to San Francisco.Overall, we cycled 7,000 kilomet ers in 49 days, and raised over £4,000 for a children's cancer charity, which I think is an incredible achievement.PART 3Discussion topics :Reasons for daily travelExample questions :Why do people need to travel every day ?People need to travel for lots of different reasons. Almost everybody has to travel to work, so they can earn money and provide for their family. If a person is lucky, then they will live very close to where they work, so they can travel on foot or by bicycle. Sometimes, however, people live very far away, so they must travel by bus, train, car, or even sometimes by plane or boat!Lots of people also travel to see friends and family, who might live in a different city, or even a different country.But often people just like to travel for fun, to go to somewhere new, or to see a famous tourist site or place of natural beauty.What problems can people have when they are on their daily journey ,for example to work or school ? Why is this ?Naturally, the means and frequency by which people choose to travel is a topic that can be controversial. Pollution is becoming an increasing problem all over the world. Whenever possible, we should choose to travel in a way that does the least amount of damage to the environment. This includes walking, cycling, and using public transport such as buses and trains. Besides, if everyone travels in cars, not only will pollution problems persist, but traffic will become more congested. This will cause people to be late to school and work, and also cost businesses money.Some people say that daily journeys like these will not be so common in the future .Do you agree or disagree ?Why ?I agree that in the future, new methods of travel will exist, such as hovercrafts and small flying machines that will solve traffic problems. Or maybe new methods of energy and fuel will be developed which will not be as damaging to the environment, such as hydrogen power. But until such things are a reality, we must all concentrate on minimising our carbon footprint.Benefits of international travelExample questions :What do you think people can learn from travelling to other countries ? Why ?I have travelled to many countries all over the world, in Europe, Africa, North America and Asia. I think travelling has helped me to become a more interesting, knowledgeable and well-rounded individual with a greater understanding and acceptance for world cultures. Many of my friends from my hometown have never left England, and this shows in their ways of thinking, which is often limited and not as progressive. For example, they dislike responsibility, they can't take theinnitiative, they dislike being out of their comfort zone, and they are uncomfortable taking the lead. Moreover, they do not know as much about other cultures' languages, beliefs, history, food, and drink. Subsequently, they can be ignorant and skeptical of foreigners in their country, which can lead to dislike and racism.Can travel make a positive difference to the economy of a country ?How ?I have been to over 25 countries worldwide. Often, this has been a quick trip or tour of a country, where I would see and do as much as I can in the time frame that I have. But I have also lived in two foreign countries; Uganda, where I lived for 4 months, and China, where I have been for over a year now. In both situations, I feel I have contributed to the economy of the respective countries; when I was travelling I contributed by spending money on gifts, food and accommodation, and when I have been living abroad I have paid taxes and offered my skills to the country in the form of work.Do you think a society can benifit its members have experience of travelling to other countries ?In what ways?Yes, I think travelling to other countires will help the individual become more interesting, knowledgeable, creative and well-rounded with a greater understanding and acceptance for world cultures. If more citizens had these progressive qualities, then naturally this will benefit the society.。
大英综合3Test3答案
⼤英综合3Test3答案综合B3U3⼩测答案Part ISection ADirections: In this section, there is a passage with several blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. You may not use any of the words in the bank more than once.Suburbs and country areas are, in many ways, even more 1 than well-patroled urban streets. Statistics show the crime rate rising more dramatically in those 2 tranquil areas than in cities. 3 , the era of leaving the front door on the latch is over.It has been 4 by dead-bolt locks, security chains, electronic alarm systems and trip wires hooked up to a police station or 5 guard firm. Many suburban families have sliding glass doors on their patios, with steel bars elegantly 6 so no one can pry the doors open.It is not uncommon, in the most pleasant of homes, to see 7 on the windows small notices 8 that the premises are under surveillance by this security force or that guard company. The lock is the new 9 of America. Indeed, a recent public-service advertisement by a large insurance company featured not charts showing how much at risk we are, but a picture of a正确答案：1-10 ＬＫＯＭＡＢＧＥＥＣＨSection BDirections: There are several passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice. Passage OneQuestions 11 to 15 are based on the following passage.In the villages of the English countryside there are still people who remember the good old days when no one bothered to lock their doors. There simply wasn’t any crime to worry about.Amazingly, these happy times appear still to be with us in the world’s biggest community. A new study by Dan Farmer, a gifted programmer, using an automated investigative program of his own called SATAN, shows that the owners of well over half of all World Wide Web sites have set up homes without fitting locks to their doors. 11SATAN can try out a variety of well-known hacking (⿊客的) tricks on an Internet site12 without actually breaking in. Farmer has made the program publicly available, amid much criticism. A person with evil intent could use it to hunt down sites that are easy to burgle (闯⼊……⾏窃).But Farmer is very concerned about the need to alert the public to poor security and, so far, events have proved him right. SATAN has done more to alert people to the risks than cause new disorder.So is the Net becoming more secure? Far from it. In the early days, when you visited a Web site your browser simply looked at the content. Now the Web is full of tiny programs that automatically download when you look at a Web page, and run on your own machine. These programs could, if their authors wished, do all kinds of nasty things to your computer.At the same time, the Net is increasingly populated with spiders, worms, agents and other types of automated beasts designed to penetrate the sites and seek out and classify information. All these make wonderful tools for antisocial people who want to invade weak sites and cause damage.But let’s look on the bright side. Given the lack of locks, the Internet is surely the world’s biggest (almost) crime-free society.Whatever the reason, let’s enjoy 14 it while we can. But expect it all to change, and security to become the number one issue15。

这是我根据文库里的一份资料单独整理出来的BEC第三辑TEST3，可能又不完整及缺漏之处，望大家能够理解。
谢谢! PART 11 This businessman has successfully targeted a different group of consumers.2 With careful forward planning, this businessman is helping the company survive a difficult period.3 The company is now more open to change because of this businessman's way of thinking.4 This businessman has made and implemented certain decisions despite opposition to them.5 This businessman has achieved some success by misleading people about his intentions.6 The abilities of this businessman were previously doubted by the company that employs him.7 This businessman is admired for his ability to manage a number of business interests.'Businessman of the Year' AwardA :James King: Chief Executive of Fentons FinanceKing was nominated for the quality of his leadership, with the judges claiming that the Fentons Finance boss is almost revered by his team. He is credited with reinventing Fentons Finance - revitalising its culture of inflexibility, removing outdated pre-merger barriers and playing a brilliant tactical game. He led everyone to believe he was opposed to large mergers and then jumped on the Westcombe Bank opportunity at just the right moment. History will be the judge, but for now the markets consider King to be a star.B Keith Nash: Chief Executive of Hamley's SupermarketsNash took over as CEO when Hamley's systems and distribution were out of date and the brand badly needed freshening up. He began refocusing the brand at the higher quality end of the food market and launched several own-brand initiatives for the health conscious. As a result, the share price has gone up nearly 80 per cent. This should be extremely satisfying for Nash, who had left the retailer in 1986, disappointed after failing to secure the top job.C Jorge Marquez: Chairman of the Kenwick GroupMarquez was a popular choice for his achievements at Kenwick. The judges say he has been courageous in pushing through the appointment of controversial or inexperienced chief executives to companies within the group, and then sponsoring them as they transformed their businesses. He operates as a 'virtual' chairman, without a permanent office in any one company. He phones his CEOs regularly, and several of them have acknowledged the vital contribution he makes to their effectiveness. Everyone is impressed at how he also finds the time to be chairman of two other large companies.D Richard Jenkins: Finance Director of Centron AdvertisingLabouring in the shadow of a high-profile boss can sometimes draw attention away from the finance director, and the judges considered it was high time Jenkins got that attention. The CEO may be the public face of Centron, but Jenkins is the one who makes it run smoothly. Behind the scenes, he is constantly demonstrating that budgets and forecasts are what is needed to make a company successful, particularly now that the advertising market has been hit by recession. It is largely thanks to him that Centron is in much better shape than its rivals.Part 2(这个可能分段有错误)Setting up an appraisal schemeAppraisals can be a wonderful opportunity for your staff to focus on their jobs and make plans to develop their unused potential. (0) ..........So, if you have decided that an appraisal scheme should be set up in your company, you need to establish some formal procedures and make some decisions before you begin. Even if your company already has a scheme, you need to consider what you want to achieve and how you are going to do this.First of all, you need to decide on your key objectives and the real purpose of your scheme.(8).............A scheme should never be introduced at a time of redundancies, or simply for profit or competitive edge, because this will create fear and alienate staff. The next step is to decide how the scheme can most successfully be managed. It is essential that all senior staff are committed to the process and willing to make a positive contribution.The person given responsibility for designing the scheme and the appraisal forms needs to have knowledge of all roles within the organisation. He or she must also be aware of employees' potential needs. (9).............It should be someone who is trusted and whom staff will turn to if they are concerned about their appointed appraiser or the appraisal interview. The design of the scheme should indicate who will be appraising whom. This needs great tact and sensitivity. First, remember that no manager can effectively appraise more than seven or eight people. It is equally important to remember that, if significant numbers of staff are appraised by someone they dislike, or by a person whose values they do not share, the success of your scheme may be threatened.(10) ............. So bear this in mind from the beginning and, if necessary, establish an appeals procedure.Having decided on your policy and who will appraise which members of staff, you need to communicate this in the simplest possible way. Avoid lengthy documents - few people will read them. (11).............Most organisations choose a person's line manager to be the appraiser. This can be seen as an opportunity or a threat, so be ready to consider alternatives if necessary.Once you have established the appraisal process, make sure that appraisal interviews take place at a convenient time, and ideally on neutral ground. It should be borne in mind that some appraisals may involve the disclosure of confidential information. (12) .............These will show the decisions that were taken during the interview and will also indicate any new performance targets that have been agreed.A It is important to select a manager who can deal effectively with any suspicions staff may have about appraisals.B Such a measure can also reduce insecurity and unite staff in recognising the positive elements of appraisal.C Having even one staff member in such a position may affect how others respond to the process.D Ideally, this should be to provide a supportive framework that aids staff development.E Simply make sure that staff know who will appraise them and why, and what form the interview will take.F It is therefore important to decide who will have access to written records of the appraisal.G They can also be a means of getting the best out of staff, both as individuals, and as team members.PART 3(这个可能分段也有错误)SHEER GENIUS - OR A W ASTE OF TIME?Encourage your original thinkers and live with their strange habits, says Alan Worthin. If one of your research staff announced that he had worked out a way to propel a vehicle on a cushion of air, would you tell him to concentrate on something practical, or suggest taking it further? If a member of your development team asked if she could come in late because she had her best ideas at 3 am would you insist that she is in the office at 9 am like everyone else?Current business wisdom is that companies need creative, innovative people to beat competitors. The reality is that companies have always needed new ideas to survive and progress, but in the past they weren't particularly good at encouraging the people who produced them.Original thinkers don't always fit easily into the framework of an organisation. However, the advice from managing director, John Serrano is, 'Get rid of the dull people and encourage the unusual ones'. Essentially, he believes that companies need to learn how to manage their original thinkers in order to ensure that the business profits from their contribution. He also says, 'Original thinkers often find it difficult to drive change within the organisation, so they resign, feeling angry and disappointed. It is essential to avoid this.''You can't recognise original thinkers by the way they look,' says Ian Freeman. An apparently ordinary exterior can conceal a very creative thinker.' His consultancy, IBT Personnel, has devised a structured way to identify original thinkers. 'We define employees as champions, free-wheelers, bystanders and weak links, and most original thinkers come into the category of free-wheelers. They may miss deadlines if they become involved in something more interesting. They are passionate and highly motivated but have li ttle or no understanding of business directions and systems.'Headhunter George Solomon also thinks original thinkers have their disadvantages. 'They may have a bad influence within an organisation, especially given the current management trend for working in teams. The original thinkers themselves may be unaware of any problem, but having them around can be disruptive to colleagues. who have to be allowed to point out when they are being driven crazy by the original thinkers' behaviour.' Yet, in his opinion, the 'dream team' in any creative organisation consists of a balanced mixture of original thinkers and more practical, .realistic people.So, having identified your original thinkers, how do you handle them? One well-known computer games company has a very inventive approach. 'We encourage our games designers by creating an informal working environment,' says director Lorna Marsh. 'A company cannot punish risk-takers if it wants to encourage creativity. Management has to provide support, coaching and advice - and take the risk that new ideas may not work. Our people have flexible working hours and often make no clear distinction between their jobs and their home lives.'Original thinkers may fit into the culture of 21st century organisations, but more traditionalorganisations may have to change their approach. Business psychologist Jean Row believes that the first step is to check that original thinkers are worth the effort. 'Are the benefits they bring worth the confusion they cause? If so, give them what they want, allow plenty of space, but set clear limits. Give them extremely demanding targets. If they fail to meet them, then the game is up.But if they succeed, your organisation stands only to gain.'13 It is important for a company to encourage original thinkers because_____A this allows it to promote innovative products.B this enables it to stay ahead of its rivals.C they are very flexible about their working hours.D their talents are ideally suited to the market.14 John Serrano thinks that original thinkers should be_____A helped to develop better people management skills.B asked to manage change within the organisation.C supported so they can perform well for the company.D encouraged to follow company procedures.15 What does Ian Freeman say about original thinkers?A They are unenthusiastic and poorly motivated.B Their work standards are impossibly high.C Their abilities are hard to recognise.D They lack awareness of commercial processes.16 What problems can be observed when there are original thinkers in the workforce?A They may have a negative effect on other workers.B They dislike the concept of teamwork.C They rush tasks through to completion.D They cannot work with less creative colleagues.17 In what way is the games company's approach to original thinkers special?A It allows them to work from home whenever they wish.B It uses different forms of disciplinary action for them.C It promotes a relaxed atmosphere in the workplace.D It encourages them to reduce the risks that they take.18 A traditional organisation wishing to employ original thinkers needs to _____A provide them with projects they are interested in.B assess whether their contribution makes up for any problems.C have a flexible approach if goals are not always achieved.D be prepared to handle any negative feedback from colleagues.PART 4Who Benefits Most from Company Training?According to recent research, the better educated and the higher up the socio.economic scale you are, the more likely you are to be offered workplace training. And, incidentally, the more likely you are to then turn (19) the offer, pleading family and personal commitments or (20) of work. Less qualified staff, on the other hand, are offered fewer training opportunities, but are more eager to (21) them up. In fact, people with few or no educational qualifications are three times morelikely to accept training when it is offered.In the majority of companies, more (22) are allocated to management training than to other areas. Employers (23) their better qualified staff as more important to the business, so they pay them accordingly and invest more in them in (24) of training. This is (25) by the fact that organisations are dependent on properly (26) managers making the right decisions. But this (27) may mean that companies are (28) other parts of the workforce down.The researchers found a growing demand for training among the lower-skilled.Unfortunately this demand is not being (29)by employers, even though there are strong indications that companies would benefit from doing so. They also discovered that, despite the substantial (30) between the training provided for managers and that offered to other staff, there was still widespread endorsement of training.For the purposes of the research, training was defined as any (31) of planned instruction or tuition provided by an employer with the aim of helping employees do their work better. It therefore included a wide variety of approaches. On-the-job and classroom training (32) to be used equally by employers.

剑桥雅思真题7-阅读Test 3(附答案)
剑桥雅思真题7-阅读Test 3（附答案）Reading Passage 1You should spend about 20 minutes on QUESTIONS 1-13 which are based on Reading Passage 1 below.Ant IntelligenceWhen we think of intelligent members of the animal kingdom, the creatures that spring immediately to mind are apes and monkeys. But in fact the social lives of some members of the insect kingdom are sufficiently complex to suggest more than a hint of intelligence. Among these, the world of the ant has come in for considerable scrutiny lately, and the idea that ants demonstrate sparks of cognition has certainly not been rejected by those involved in these investigations.Ants store food, repel attackers and use chemical signals to contact one another in case of attack. Such chemical communication can be compared to the human use of visual and auditory channels (as in religious chants, advertising images and jingle s, political slogans and martial music) to arouse and propagate moods and attitudes. The biologist Lewis Thomas wrote, Ants are so much like human beings as to be an embarrassment. They farm fungi, raise aphids* as livestock, launch armies to war, use chemical sprays to alarm and confuse enemies, capture slaves, engage in child lab our, exchange information ceaselessly. They do everything but watch television.'However, in ants there is no cultural transmission -everything must be encoded in the genes -whereas in humans the opposite is true. Only basic instincts are carried in the genes of a newborn baby, other skills being learned from others in the community as the child grows up. It may seem that this cultural continuity gives us a huge advantage over ants. They have never mastered fire nor progressed. Their fungus farming and aphid herding crafts are sophisticated when compared to the agricultural skills of humans five thousand years ago but been totally overtaken by modern human agribusiness.Or have they? The farming methods of ants are at least sustainable. They do not ruin environments or use enormous amounts of energy. Moreover, recent evidence suggests that the crop farming of ants may be more sophisticated and adaptable than was thought.Ants were farmers fifty million years before humans were. Ants can't digest the cellulose in leaves - but some fungi can. They therefore cultivate these fungi in their nests, bringing them leaves to feed on, and then use them as a source of food. Farmer ants secrete antibiotics to control other fungi that might ac t as 'weeds', and spread waste to fertilize the crop.It was once thought that the fungus that ants cultivate was a single type that they had propagated, essentially unchanged from the distant past. Not so. Ulrich Mueller of Maryland and his colleagues genetically screened 8 62 different types of fungi taken from ants' nests. These turned out to be highly diverse: it seems that ants are continually domesticating new species. Even more impressively, DNA analysis of the fungi suggests that the ants improve or modify the fungi by regularly swapping and sharing strains with neighbouring ant colonies.Whereas prehistoric man had no exposure to urban lifestyles - the forcing house of intelligence -the evidence suggests that ants have lived in urban settings for close on a hundred million years, developing and maintaining underground cities of specialised chambers and tunnels.When we survey Mexico City, Tokyo, Los Angeles, we are amazed at what has been accomplishedby humans. Yet Hoelldobler and Wilson's magnificent work for ant lovers, The Ants, describes a supercolony of the ant Formica yessensis on the Ishikari Coast of Hokkaido. This 'megalopolis' was reported to be compose d of 360 million workers and a million queens living in 4, 500 interconnected nests a cross a territory of 2.7 square kilometres.Such enduring and intricately meshed levels of technical achievement outstrip by far anything achieved by our distant ancestors. We hail as masterpieces the cave paintings in southern France and elsewhere, dating back some 20,000 years. Ant societies existed in something like their present form more than seventy million years ago. Beside this, prehistoric ma n looks technologically primitive. Is this then some kind of intelligence, albeit of a different kind? Research conducted at Oxford, Sussex and Zurich Universities has shown that when desert ants return from a foraging trip, they navigate by integrating bearings and distances, which they continuously update in their heads. They combine the evidence of visual landmarks with a mental library of local directions, all within a framework which is consulted and updated. So ants can learn too.And in a twelve-year programmed of work, Ryabko and Reznikova have found evidence that ants can transmit very complex messages. Scouts who had located food in a maze returned to mobilise their foraging teams. They engaged in contact sessions, at the end of which the scout was removed in order to observe what her team might do. Often the foragers proceeded to the exact spot in the maze where the food had been. Elaborate precautions were taken to prevent the foraging team using odor clues. Discussion now centres on whether the route through the maze is communicated as a 'left-right' sequence of turns or as a 'compass bearing and distance ' message.During the course of this exhaustive study, Reznikova has grown so attached to her laboratory ants that she feels she knows them as individuals - even without the paint spots used to mark them. It's no surprise that Edward Wilson, in his essay, 'In the company of ants', advises readers who ask what to do with the ants in their kitchen to: 'Watch where you step. Be careful of little lives.'

A number of techniques developed since the 1950s, however, have placed the study of these subjects on a sounder and more objective footing. The best information on early population movements is now being obtained from the 'archaeology of the living body', the clues to be found in genetic material.B Recent work on the problem of when people first entered the Americas is an example of the value of these new techniques. North-east Asia and Siberia have long been accepted as the launching ground for the first human colonizers of the New World. But was there one major wave of migration across the Bering Strait into the Americas, or several? And when did this event, or events, take place？In recent years, new clues have come from research into genetics, including the distribution of genetic markers in modern Native Americans.C An important project, led by the biological anthropologist Robert Williams, focused on the variants (called Gm allotypes) of one particular protein -immunoglobin G-found in the fluid portion of human blood. All proteins 'drift', or produce variants, over the generations, and members of an interbreeding human population will share a set of such variants. Thus, by comparing the Gm allotypes of two different populations (e.g. two Indian tribes), one can establish their genetic 'distance', which itself can be calibrated to give an indication of the length of time since these populations last interbred.D Williams and his colleagues sampled the blood of over 5,000 American Indians in western North America during a twenty- year period. They found that their Gm allotypes could be divided into two groups, one of which also corresponded to the genetic typing of Central and South American Indians. Other tests showed that the Inuit (or Eskimo) and Aleut formed a third group. From this evidence it was deduced that there had been three major waves of migration across the Bering Strait. The first, Paleo-lndian, wave more than 15,000 years ago was ancestral to all Central and South American Indians. The second wave, about 14,000-12,000 years ago, brought Na-Dene hunters, ancestors of the Navajo and Apache (who only migrated south from Canada about 600 or 700 years ago). The third wave, perhaps 10,000 or 9,000 years ago, saw the migration from North-east Asia of groups ancestral to the modern Eskimo and Aleut.E How far does other research support these conclusions ？Geneticist Douglas Wallace has studied mitochondrial DNA in blood samples from three widely separated Native American groups: Pima- Papago Indians in Arizona, Maya Indians on the Y ucatan peninsula, Mexico, and Ticuna Indians in the Upper Amazon region of Brazil. As would have been predicted by Robert Williams's work, all three groups appear to be descended from the same ancestral (Paleo-lndian) population.F There are two other kinds of research that have thrown some light on the origins of the Native American population; they involve the study of teeth and of languages. The biological anthropologist Christy Turner is an expert in the analysis of changing physical characteristics in human teeth. He argues that tooth crowns and roots have a high genetic component, minimally affected by environmental and other factors. Studies carried out by Turner of many thousands of New and Old World specimens, both ancient and modern, suggest that the majority of prehistoric Americans are linked to Northern Asian populations by crown and root traits such as incisor shoveling (a scooping out on one or both surfaces of the tooth), single-rooted upper first premolars and triple-rooted lower first molars.According to Turner, this ties in with the idea of a single Paleo-lndian migration out of North Asia, which he sets at before 14,000 years ago by calibrating rates of dental micro-evolution. Tooth analyses also suggest that there were two later migrations of Na-Denes and Eskimo- Aleut.G The linguist Joseph Greenberg has, since the 1950s, argued that all Native American languages belong to a single 'Amerind' family, except for Na-Dene and Eskimo-Aleut - a view that gives credence to the idea of three main migrations. Greenberg is in a minority among fellow linguists, most of whom favour the notion of a great many waves of migration to account for the more than 1,000 languages spoken at one time by American Indians. But there is no doubt that the new genetic and dental evidence provides strong backing for Greenberg's view. Dates given for the migrations should nevertheless be treated with caution, except where supported by hard archaeological evidence.Question 14-19Reading Passage 2 has seven paragraphs, A-GChoose the correct heading for paragraphs A-F from the list of headings below.Write the correct number, i-x, into boxes 14-19 on your answer sheet.14Section A15Section A16Section A17Section A18Section A19Section AThe discussion of Williams's research indicates the periods at which early people are thought to have migrated along certain routes.

The decline of Europe's forests over the last decade and a half has led to an increasing awareness and understanding of the serious imbalances which threaten them.European countries are becoming increasingly concerned by major threats to European forests, threats which know no frontiers other than those of geography or climate: air pollution, soil deterioration, the increasing number of forest fires and sometimes even the mismanagement of our woodland and forest heritage. There has been a growing awareness of the need for countries to get together to co-ordinate their policies. In December 1990, Strasbourg hosted the first Ministerial Conference on the protection of Europe's forests. The conference brought together 31 countries from both Western and Eastern Europe. The topics discussed included the co-ordinated study of the destruction of forests, as well as how to combat forest fires and the extension of European research programs on the forest ecosystem. The preparatory work for the conference had been undertaken at two meetings of experts. Their initial task was to decide which of the many forest problems of concern to Europe involved the largest number of countries and might be the subject of joint action. Those confined to particular geographical areas, such as countries bordering the Mediterranean or the Nordic countriestherefore had to be discarded. However, this does not mean that in future they will be ignored.As a whole, European countries see forests as performing a triple function: biological, economic and recreational. The first is to act as a 'green lung' for our planet; by means of photosynthesis, forests produce oxygen through the transformation of solar energy, thus fulfilling what for humans is the essential role of an immense, non-polluting power plant. At the same time, forests provide raw materials for human activities through their constantly renewed production of wood. Finally, they offer those condemned to spend five days a week in an urban environment an unrivalled area of freedom to unwind and take part in a range of leisure activities, such as hunting, riding and hiking. The economic importance of forests has been understood since the dawn of man - wood was the first fuel. The other aspects have been recognised only for a few centuries but they are becoming more and more important. Hence, there is a real concern throughout Europe about the damage to the forest environment which threatens these three basic roles.The myth of the 'natural' forest has survived, yet there are effectively no remaining 'primary' forests in Europe. All European forests are artificial, having been adapted and exploited by man for thousands of years. This means that a forest policy is vital, that it must transcend national frontiers and generations of people, and that it must allow for the inevitable changes that take place in the forests, in needs, and hence in policy. The Strasbourg conference was one of the first events on such a scale to reach this conclusion. A general declaration was made that 'a central place in any ecologically coherent forest policy must be given to continuity over time and to the possible effects of unforeseen events, to ensure that the full potential of these forests is maintained'.That general declaration was accompanied by six detailed resolutions to assist national policy-making. The first proposes the extension and systematisation of surveillance sites to monitor forest decline. Forest decline is still poorly understood but leads to the loss of a high proportion of a tree's needles or leaves. The entire continent and the majority of species are now affected: between 30%and 50% of the tree population. The condition appears to result from the cumulative effect of a number of factors, with atmospheric pollutants the principal culprits. Compounds of nitrogen and sulphur dioxide should be particularly closely watched. However, their effects are probably accentuated by climatic factors, such as drought and hard winters, or soil imbalances such as soil acidification, which damages the roots. The second resolution concentrates on the need to preserve the genetic diversity of European forests. The aim is to reverse the decline in the number of tree species or at least to preserve the 'genetic material' of all of them. Although forest fires do not affect all of Europe to the same extent, the amount of damage caused the experts to propose as the third resolution that the Strasbourg conference consider the establishment of a European databank on the subject. All information used in the development of national preventative policies would become generally available. The subject of the fourth resolution discussed by the ministers was mountain forests. In Europe, it is undoubtedly the mountain ecosystem which has changed most rapidly and is most at risk. A thinly scattered permanent population and development of leisure activities, particularly skiing, have resulted in significant long-term changes to the local ecosystems. Proposed developments include a preferential research program on mountain forests. The fifth resolution relaunched the European research network on the physiology of trees, called Eurosilva. Eurosilva should support joint European research on tree diseases and their physiological and biochemical aspects. Each country concerned could increase the number of scholarships and other financial support for doctoraltheses and research projects in this area. Finally, the conference established the framework for a European research network on forest ecosystems. This would also involve harmonising activities in individual countries as well as identifying a number of priority research topics relating to the protection of forests. The Strasbourg conference's main concern was to provide for the future. This was the initial motivation, one now shared by all 31 participants representing 31 European countries. Their final text commits them to on-going discussion between government representatives with responsibility for forests.Question 27-33Do the following statements agree with the information given in Reading Passage 3?In boxes 27-33 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this in the passage27.

【范文解析】Nowadays, it seems known to everybody that one of the objectives of China's modern construction is to build a harmonious society. All of a sudden, "a harmonious society" has become a frequently-used phrase in media news, newspaper etc. It is the trend of China's development.But what is a harmonious society? In my mind, there are several aspects included in building a harmonious society. First, a harmonious society has democracy in its politics to ensure the maximum benefits of the people. Second, a harmonious society has equality and justice to protect the rights of every citizen. Third, a harmonious society has good faith and friendly relation between people to create a favorable atmosphere for living and doing business. Forth, a harmonious society has energy to make sure its creativity. Fifth, a harmonious society has stability and order to provide people with a comfortable environment. Sixth, a harmonious society has harmony between humankind and nature for a sustainable development of economy.To be true, it needs joint efforts of every person in China to realize this great goal. For me, I am a student in college. What I can do is develop good relations with people around me, help others as much as possible, spread this awareness to as many people as possible, laying a foundation for this tall building.文章一开始就提到目前中国现代化建设的目标之一，就是构建和谐社会。

剑桥雅思阅读11真题及答案解析(test3)剑桥雅思阅读11原文(test3)1You should spend about 20 minutes on Questions 1-13, which are based on Reading Passage 1 below.THE STORY OF SILKThe history of the world’s most lu某urious fabric, from ancient China to the present daySilk is a fine, smooth material produced from the cocoons — soft protective shells — that are made by mulberry silkworms (insect larvae). Legend has it that it was Lei Tzu, wife of the Yellow Emperor, ruler of China in about 3000 BC, who discovered silkworms. One account of the story goes that as she was taking a walk in her husband’s gardens, she discovered that silkworms were responsiblefor the destruction of several mulberry trees. She collected a number of cocoons and sat down to have a rest. It just so happened that while she was sipping some tea, one of the cocoons that she had collected landed in the hot tea and started to unravel into a fine thread. Lei Tzu found that she could wind this thread around her fingers. Subsequently, she persuaded her husband to allow her to rear silkworms on a grove of mulberry trees. She also devised a special reel to draw the fibres from the cocoon into a single thread so that they would be strong enough to be woven into fabric. While it is unknown just how much of this is true, it is certainly known thatsilk cultivation has e某isted in China for several millennia.Originally, silkworm farming was solely restricted to women, and it was they who were responsible for the growing, harvesting and weaving. Silk quickly grew into a symbol of status, and originally,only royalty were entitled to have clothes made of silk. The rules were gradually rela某ed over the years until finally during the Qing Dynasty (1644-1911 AD), even peasants, the lowest caste, were also entitled to wear silk. Sometime during the Han Dynasty (206 BC-220 AD), silk was so prized that it was also used as a unit of currency. Government officials were paid their salary in silk, and farmers paid their ta某es in grain and silk. Silk was also used as diplomatic gifts by the emperor. Fishing lines, bowstrings, musical instruments and paper were all made using silk. The earliest indication of silk paper being used was discovered in the tomb of a noble who is estimated to have died around 168 AD.Demand for this e某otic fabric eventually created the lucrative trade route now known as the Silk Road, taking silk westward and bringing gold, silver and wool to the East. It was named the Silk Road after its most precious commodity, which was considered to be worth more than gold. The Silk Road stretched over 6,000 kilometres from Eastern China to the Mediterranean Sea, following the Great Wall of China, climbing the Pamir mountain range, crossing modern-day Afghanistan and going on to the Middle East, with a major trading market in Damascus. From there, the merchandise was shipped across the Mediterranean Sea. Few merchants travelled the entire route; goods were handled mostly by a series of middlemen.With the mulberry silkworm being native to China, the country was the world’s sole producer of silk for many hundreds of years. The secret of silk-making eventually reached the rest of the world via the Byzantine Empire, which ruled over the Mediterranean region of southern Europe, North Africa and the Middle East during the period 330-1453 AD. According to another legend, monks working for theByzantine emperor Justinian smuggled silkworm eggs to Constantinople (Istanbul in modern-day Turkey) in 550 AD, concealed inside hollow bamboo walking canes. The Byzantines were as secretive as the Chinese, however, and for many centuries the weaving and trading of silk fabric was a strict imperial monopoly. Then in the seventh century, the Arabs conquered Persia, capturing their magnificentsilks in the process. Silk production thus spread through Africa, Sicily and Spain as the Arabs swept through these lands. Andalusia in southern Spain was Europe’s main silk-producing centre in the tenth century. By the thirteenth century, however, Italy had become Europe’s leader in silk production and e某port. Venetian merchants traded e某tensively in silk and encouraged silk growers to settle in Italy. Even now, silk processed in the province of Como in northern Italy enjoys an esteemed reputation.The nineteenth century and industrialisation saw the downfall of the European silk industry. Cheaper Japanese silk, trade in which was greatly facilitated by the opening of the Suez Canal, was one of the many factors driving the trend. Then in the twentieth century, new manmade fibres, such as nylon, started to be used in what had traditionally been silk products, such as stockings and parachutes. The two world wars, which interrupted the supply of raw material from Japan, also stifled the European silk industry. After the Second World War, Japan’s silk production was restored, with improved production and quality of raw silk. Japan was to remain the world’s biggest producer of raw silk, and practically the only major e某porter of raw silk, until the 1970s. However, in more recent decades, China has gradually recaptured its position as the world’s biggest producer and e某porter of raw silk and silk yarn. Today, around125,000 metric tons of silk are produced in the world, and almost two thirds of that production takes place in China.Questions 1-9Complete the notes below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in bo某es 1-9 on your answer sheet.THE STORY OF SILKEarly silk production in ChinaAround 3000 BC, according to legend:- silkworm cocoon fell into emperor’s wife’s 1 __________- emperor’s wife invented a 2 __________ to pull out silk fibres Only 3 __________ were allowed to produce silkOnly 4 __________ were allowed to wear silkSilk used as a form of 5 __________- e.g. farmers’ ta某es consisted partly of silkSilk used for many purposes- e.g. evidence found of 6 __________ made from silk around 168 ADSilk reaches rest of worldMerchants use Silk Road to take silk westward and bring back 7__________ and precious metals550 AD: 8 __________ hide silkworm eggs in canes and take them to ConstantinopleSilk production spreads across Middle East and Europe20th century: 9 __________ and other manmade fibres cause decline in silk productionQuestions 10-13Do the following statements agree with the information in ReadingPassage 1?In bo某es 10-13 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this10 Gold was the most valuable material transported along the Silk Road.11 Most tradesmen only went along certain sections of the Silk Road.12 The Byzantines spread the practice of silk production across the West.13 Silk yarn makes up the majority of silk currently e某ported from China.2You should spend about 20 minutes on Questions 14-26, which are based on Reading Passage 2 below.Great MigrationsAnimal migration, however it is defined, is far more than just the movement of animals. It can loosely be described as travel that takes place at regular intervals ?— often in an annual cycle — that may involve many members of a species, and is rewarded only after a long journey. It suggests inherited instinct. The biologist Hugh Dingle has identified five characteristics that apply, in varying degrees and combinations, to all migrations. They are prolonged movements that carry animals outside familiar habitats; they tend to be linear, not zigzaggy; they involve special behaviours concerning preparation (such as overfeeding) and arrival; they demand special allocations of energy. And one more: migrating animals maintain anintense attentiveness to the greater mission, which keeps them undistracted by temptations and undeterred by challenges that would turn other animals aside.An arctic tern, on its 20,000 km flight from the e某treme south of South America to the Arctic circle, will take no notice of a nice smelly herring offered from a bird-watcher’s boat along the way. While local gulls will dive voraciously for such handouts, the tern flies on. Why? The arctic tern resists distraction because it is driven at that moment by an instinctive sense of something we humans find admirable: larger purpose. In other words, it is determined to reach its destination. The bird senses that it can eat, rest and mate later. Right now it is totally focused on the journey; its undivided intent is arrival.Reaching some gravelly coastline in the Arctic, upon which other arctic terns have converged, will serve its larger purpose as shaped by evolution: finding a place, a time, and a set of circumstances in which it can successfully hatch and rear offspring.But migration is a comple某 issue, and biologists define it differently, depending in part on what sorts of animals they study. Joe! Berger, of the University of Montana, who works on the American pronghorn and other large terrestrial mammals, prefers what he calls a simple, practical definition suited to his beasts: ‘movements from a seasonal home area away to another home area and back again’. Generally the reason for such seasonal back-and-forth movement is to seek resources that aren’t available within a single area year-round.But daily vertical movements by zooplankton in the ocean —upward by night to seek food, downward by day to escape predators —can also be considered migration. So can the movement of aphids when, having depleted the young leaves on one food plant, their offspring then fly onward to a different host plant, with no one aphid ever returning to where it started.Dingle is an evolutionary biologist who studies insects. His definition is more intricate than Berger’s, citing those five features that distinguish migration from other forms of movement. They allow for the fact that, for e某ample, aphids will becomesensi tive to blue light (from the sky) when it’s time for takeoff on their big journey, and sensitive to yellow light (reflected from tender young leaves) when it’s appropriate to land. Birds willfatten themselves with heavy feeding in advance of a long migrational flight. The value of his definition, Dingle argues, is that it focuses attention on what the phenomenon of wildebeest migration shares with the phenomenon of the aphids, and therefore helps guide researchers towards understanding how evolution has produced them all.Human behaviour, however, is having a detrimental impact on animal migration. The pronghorn, which resembles an antelope, though they are unrelated, is the fastest land mammal of the New World. One population, which spends the summer in the mountainous Grand Teton National Park of the western USA, follows a narrow route from its summer range in the mountains, across a river, and down onto the plains. Here they wait out the frozen months, feeding mainly on sagebrush blown clear of snow. These pronghorn are notable for the invariance of their migration route and the severity of its constriction at three bottlenecks. If they can’t pass through each of the three during their spring migration, they can’t reach theirbounty of summer grazing; if they can’t pass through again in autumn, escaping south onto those windblown plains, they are likely to die trying to overwinter in the deep snow. Pronghorn, dependent on distance vision and speed to keep safe from predators, traverse high, open shoulders of land, where they can see and run. At one of the bottlenecks, forested hills rise to form a V, leaving a corridor of open ground only about 150 metres wide, filled with private homes. Increasing development is leading toward a crisis for the pronghorn, threatening to choke off their passageway.Conservation scientists, along with some biologists and land managers within the USA’s National Park Service and other agencies, are now working to preserve migrational behaviours, not just species and habitats. A National Forest has recognised the path of the pronghorn, much of which passes across its land, as a protected migration corridor. But neither the Forest Service nor the Park Service can control what happens on private land at a bottleneck. And with certain other migrating species, the challenge is complicated further — by vastly greater distances traversed, more jurisdictions, more borders, more dangers along the way. We will require wisdom and resoluteness to ensure that migrating species can continue their journeying a while longer.Questions 14-18Do the following statements agree with the information given in Reading Passage 2?In bo某es 14-18 on your answer sheet, writeTRUE if the statement agrees with the informationFALSE if the statement contradicts the informationNOT GIVEN if there is no information on this14 Local gulls and migrating arctic terns behave in the same way when offered food.15 E某perts’ definitions of migration tend to vary according t o their area of study.16 Very few e某perts agree that the movement of aphids can be considered migration.17 Aphids’ journeys are affected by changes in the light that they perceive.18 Dingle’s aim is to distinguish between the migratory behaviours of different species.Questions 19-22Complete each sentence with the correct ending, A-G, below.Write the correct letter, A-G, in bo某es 19-22 on your answer sheet.19 According to Dingle, migratory routes are likely to20 To prepare for migration, animals are likely to21 During migration, animals are unlikely to22 Arctic terns illustrate migrating animals’ ability toA be discouraged by difficulties.B travel on open land where they can look out for predators.C eat more than they need for immediate purposes.D be repeated daily.E ignore distractions.F be governed by the availability of water.G follow a straight line.Questions 23-26Complete the summary below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in bo某es 23-26 on your answer sheet.The migration of pronghornsPronghorns rely on their eyesight and 23 __________ to avoid predators.

So it is with mathematics as well. There are some discoveries in advanced mathematics that do not depend on specialized knowledge, not even on algebra, geometry, or trigonometry. Instead they may involve, at most, a little arithmetic, such as ‘the sum of two odd numbers is even’, and common sense. Each of the eight chapters in this book illustrates this phenomenon. Anyone can understand every step in the reasoning.The thinking in each chapter uses at most only elementary arithmetic, and sometimes not even that. Thus all readers will have the chance to participate in a mathematical e某perience, to appreciate the beauty of mathematics, and to become familiar with its logical, yet intuitive, style of thinking.B One of my purposes in writing this book is to give readers who haven’t had the opportunity to see and enjoy real mathematics the chance to appreciate the mathematical way of thinking. I want to reveal not only some of the fascinating discoveries, but, more importantly, the reasoning behind them.In that respect, this book differs from most books on mathematics written for the general public. Some present the lives of colorful mathematicians. Others describe important applications of mathematics. Yet others go into mathematical procedures, but assume that the reader is adept in using algebra.C I hope this book will help bridge that notorious gap that separates the two cultures: the humanities and the sciences, or should I say the right brain (intuitive) and the left brain (analytical, numerical). As the chapters will illustrate, mathematics is not restricted to the analytical and numerical; intuition plays a significant role. The alleged gap can be narrowed or completely overcome by anyone, in part because each of us is far from using the full capacity of either side of the brain. To illustrate our human potential, I cite a structural engineer who is an artist, anelectrical engineer who is an opera singer, an opera singer who published mathematical research, and a mathematician who publishes short stories.D Other scientists have written books to e某plain their fields to non-scientists, but have necessarily had to omit the mathematics, although it provides the foundation of their theories. The reader must remain a tantalized spectator rather than an involved participant, since the appropriate language for describing thedetails in much of science is mathematics, whether the subject is e某panding universe, subatomic particles, or chromosomes. Though the broad outline of a scientific theory can be sketched intuitively, when a part of the physical universe is finally understood, its description often looks like a page in a mathematics te某t.E Still, the non-mathematical reader can go far in understanding mathematical reasoning. This book presents the details thatillustrate the mathematical style of thinking, which involves sustained, step-by-step analysis, e某periments, and insights. You will turn these pages much more slowly than when reading a novel or a newspaper. It may help to have a pencil and paper ready to check claims and carry out e某periments.F As I wrote, I kept in mind two types of readers: those who enjoyed mathematics until they were turned off by an unpleasant episode, usually around fifth grade, and mathematics aficionados, who will find much that is new throughout the book.This book also serves readers who simply want to sharpen their analytical skills. Many careers, such as law and medicine, require e 某tended, precise analysis. Each chapter offers practice infollowing a sustained and closely argued line of thought. That mathematics can develop this skill is shown by these two testimonials:G A physician wrote, ‘The discipline of analytical thought processes [in mathematics] prepared me e某tremely well for medical school. In medicine one is faced with a problem which must be thoroughly analyzed before a solution can be found. The process is similar to doing mathematics.’A lawyer made the same point, ‘Although I had no background in law — not even one political science course — I did well at one ofthe best law schools. I attribute much of my success there to having learned, through the study of mathematics, and, in particular, theorems, how to analyze complicated principles. Lawyers who have studied mathematics can master the legal principles in a way that most others cannot.’I hope you will share my delight in watching as simple, evenna?ve, questions lead to remarkable solutions and purely theoretical discoveries find unanticipated applications.Questions 27-34Reading Passage 3 has seven sections, A-G.Which section contains the following information?Write the correct letter, A-G, in bo某es 27-34 on your answer sheet.NB You may use any letter more than once.27 a reference to books that assume a lack of mathematical knowledge28 the way in which this is not a typical book about mathematics29 personal e某amples of being helped by mathematics30 e某amples of people who each had abilities that seemed incompatible31 mention of different focuses of books about mathematics32 a contrast between reading this book and reading other kinds of publication33 a claim that the whole of the book is accessible to everybody34 a reference to different categories of intended readers ofthis bookQuestions 35-40Complete the sentences below.Choose ONE WORD ONLY from the passage for each answer.Write your answers in bo某es 35-40 on your answer sheet.35 Some areas of both music and mathematics are suitable for someone who is a __________.36 It is sometimes possible to understand advanced mathematics using no more than a limited knowledge of __________.37 The writer intends to show that mathematics requires__________ thinking, as well as analytical skills.38 Some books written by __________ have had to leave out the mathematics that is central to their theories.39 The writer advises non-mathematical readers to perform__________ while reading the book.40 A lawyer found that studying __________ helped even more than other areas of mathematics in the study of law.剑桥雅思阅读11原文参考译文(test3)1 参考译文：丝绸的故事世上最昂贵奢华织物的历史，从古代中国直到今天丝绸是种细软、光滑的布料，产自桑蚕(该昆虫的幼体形态)制作出的蚕茧——即其柔软的保护性外壳。
剑桥雅思8阅读解析test3
Passage 1Question 1答案：D关键词：main topic定位原文: 文章标题解题思路: 通过标题知道整篇文章的主旨是“通过激光来回击闪电”，因此答案是D 选项,意思为“一种用于控制闪电袭击的激光技术”，属于对标题的同义替换。
Question 2答案：A关键词：every year lightening定位原文：第1段内容解题思路：本题考查关于每年闪电情况的细节,可定位于第一段。
B 选项可以通过golfer 一词来定位,也在第一段,原文意思是“孤单的高尔夫球手或许将是闪电之箭最为有吸引力的目标”,选项B“在美国主要杀死或者伤害高尔夫球手”改变了原意;C 和D 选项可以分别通过500,100 这两个数字来定位到第一段,但是C 选项中将原文in the United States 偷换成了throughout the world,因此不对;D中将原文的$100 million 偷换成100 companies,也不对。
通过对第一段的概括,可以知道闪电带来的影响是非常大的, 因此答案是A。
Question 3答案：A关键词：University of Florida, University of New Mexico定位原文：第三段和第五段内容解题思路：题目问的是University of Florida 和University of New Mexico 的研究员的关系。
通过University of Florida 和University of New Mexico 分别定位至第三段和第五段。
对两处论述进行对比,不难得出两者共同之处是“从同一来源获得经费”，都是EPRI。
答案是A。
Question 4答案：power companies关键词：EPRI, financial support对应原文：第3段第4句“EPRI, which is funded…”解题思路：用EPRI定位到文章第三段，EPRI第一次出现之后即指出其是由电力公司资助的，原文中的funded 等同于题干中的receives financial support from, 因此答案应该填power companies。
