Competitive Advantage - DefinitionA competitive advantage is an advantage over competitors gained by offering consumers greater value, either by means of lower prices or by providing greater benefits and service that justifies higher prices. Competitive StrategiesFollowing on from his work analysing the competitive forces in an industry, Michael Porter suggested four "generic" business strategies that could be adopted in order to gain competitive advantage. The four strategies relate to the extent to which the scope of a businesses' activities are narrow versus broad and the extent to which a business seeks to differentiate its products.The four strategies are summarised in the figure below:The differentiation and cost leadership strategies seek competitive advantage in a broad range of market or industry segments. By contrast, the differentiation focus and cost focus strategies are adopted in a narrow market or industry.Strategy - DifferentiationThis strategy involves selecting one or more criteria used by buyers in a market - and then positioning the business uniquely to meet those criteria. This strategy is usually associated with charging a premium price for the product - often to reflect the higher production costs and extra value-added features provided for the consumer. Differentiation is about charging a premium price that more than covers the additional production costs, and about giving customers clear reasons to prefer the product over other, less differentiated products.Examples of Differentiation Strategy: Mercedes cars; Bang & OlufsenStrategy - Cost LeadershipWith this strategy, the objective is to become the lowest-cost producer in the industry. Many (perhaps all) market segments in the industry are supplied with the emphasis placed minimising costs. If the achieved selling price can at least equal (or near)the average for the market, then the lowest-cost producer will (in theory) enjoy the best profits. This strategy is usually associated with large-scale businesses offering "standard" products with relatively little differentiation that are perfectly acceptable to the majority of customers. Occasionally, a low-cost leader will also discount its product to maximise sales, particularly if it has a significant cost advantage over the competition and, in doing so, it can further increase its market share.Strategy - Differentiation FocusIn the differentiation focus strategy, a business aims to differentiate within just one or a small number of target market segments. The special customer needs of the segment mean that there are opportunities to provide products that are clearly different from competitors who may be targeting a broader group of customers. The important issue for any business adopting this strategy is to ensure that customers really do have different needs and wants - in other words that there is a valid basis for differentiation - and that existing competitor products are not meeting those needs and wants.Examples of Differentiation Focus: any successful niche retailers; (e.g. The Perfume Shop); or specialist holiday operator (e.g. Carrier)Strategy - Cost FocusHere a business seeks a lower-cost advantage in just on or a small number of market segments. The product will be basic - perhaps a similar product to the higher-priced and featured market leader, but acceptable to sufficient consumers. Such products are often called "me-too's".Examples of Cost Focus: Many smaller retailers featuring own-label or discounted label products.Business Strategies - Business Strategy -Differentiation StrategyIn contrast to the cost leadership strategy, implementation of a differentiation strategy means that value is provided to customers through the unique features and characteristics of a company's products rather than by the lowest price. Because differentiated products satisfy customers' unique needs or preferences, companies can charge premium prices for differentiated products.For the company to be able to outperform its competitors and earn above-average returns, the price charged for the differentiated product must exceed the cost of differentiation. In other words, the price charged must exceed total product cost. Because of this, the differentiated product's premium prices generally exceed the low price of the standard product.Companies that follow a differentiation strategy concentrate or focus on product innovation and developing product features that customers value rather than on maintaining the lowest competitive price (as is the case for the cost leadership strategy).Figure: Drivers of Differentiation StrategyProducts can be differentiated in a number of ways so that they stand apart from standardised products: ▪superior quality▪unusual or unique features▪more responsive customer service▪rapid product innovation▪advanced technological featuresFIGURE: Value-Creating Activities Associated with the Differentiation Strategy▪Rivalry with Existing Competitors Achieving customer loyalty means differentiating products in ways that are meaningful to customers. Brand loyalty means that customers will be less sensitive to price increases. As long as the company satisfies the differentiated needs of loyal customers, it may be insulated from price-based competition.▪Bargaining Power of Buyers (Customers) Through meaningful differentiation, companies develop products that are considered unique. This uniqueness may insulate the company from competitive rivalry and reduce customer sensitivity to price increases (similar to the insulation from rivalry with existing competitors). By satisfying customer preferences in ways that no competitor can, companies also are able to charge higher prices (because there are no comparable product alternatives).▪Bargaining Power of Suppliers Because the differentiator charges premium prices, they are somewhat insulated from suppliers' price increases (as the differentiator can absorb a greater level of cost increases from powerful suppliers through its higher margins). Alternatively, because of lower price sensitivity by customers, differentiators may be able to raise prices to cover increased supplier-related costs. Because of the differentiator's focus on product quality and responsiveness to customer preferences, suppliers also may be forced to provide differentiators with higher quality materials, components, or services.▪Potential Entrants The principal barrier to entry is customers' loyalty to the uniquely differentiated brand. This means that a potential entrant must either overcome (or surpass) the uniqueness of existing products or provide similarly differentiated products at a lower price to increase customer value.▪Product Substitutes Brand loyalty may effectively insulate differentiated products from substitutes. Without brand loyalty, customers may switch to substitutes that offer similar features at a lower price or to products offering more attractive features at the same price.Like the cost leadership strategy, the differentiation strategy also carries risks.Customers may decide that the cost of uniqueness is too high. In other words, the price differential between the standardised and differentiated product is too high. Perhaps the company provides a greater level of uniqueness than customers are willing to pay for.The company's means of differentiation no longer provides value to customers. For instance, what is the value of prestige or exclusivity? And, how long will they last as customers become more sophisticated? Customer learning may reduce the customer's perception of the value of the company's differentiation. Through experience, customers may learn that the extra price paid for a differentiated product no longer has the value that it once did.This loss of value through customer learning or changes in customer perceptions can be illustrated by the experiences of IBM. Initially, the IBM name on a personal computer signalled value to customers; however, clones soon challenged IBM's pre-eminent position in the PC market. As customers learned that the clone machines offered similar features at lower prices, the value attached to the IBM brand name diminished and IBM's sales continue to suffer.A fourth risk is concerned with counterfeiting. Increasingly, counterfeit goods (products that attempt to convey differentiated features to customers at significantly reduced prices) are a concern for many companies using the differentiated strategy.In the event of any of the above, differentiators are challenged to increase value to customers. This may mean reducing prices, adding product features without raising prices, or developing new efficiencies in its value chain of primary and secondary activities.。
浅谈在线课程的优劣英语作文A Brief Discussion on the Advantages and Disadvantages of Online CoursesIn recent years, with the rapid development of the Internet and technology, online courses have become increasingly popular. Online courses offer a convenient and flexible way for people to learn, and they have many advantages over traditional classroom-based courses. However, like any other form of education, online courses also have some disadvantages. In this article, we will discuss the advantages and disadvantages of online courses.One of the main advantages of online courses is their convenience and flexibility. Online courses allow students to learn at their own pace and on their own schedule. This means that students can fit their studies around their other commitments, such as work or family. Online courses also allow students to access course materials and lectures from anywhere with an Internet connection, which makes it easier for them to learn on the go.Another advantage of online courses is that they offer a wider range of courses and programs than traditional classroom-based courses. Online courses can be offered by universities and colleges from all over the world, which means that students have access to a much wider range of courses and programs than they would if they were limited to attending courses at a local institution. This can be especially beneficial for students who are interested in specialized or niche fields of study.In addition, online courses often cost less than traditional classroom-based courses. This is because online courses do not require the same level of infrastructure and resources as traditional courses, such as classrooms, textbooks, and teaching assistants. Online courses also often have lower tuition fees, which can make them more accessible to a wider range of students.However, online courses also have some disadvantages. One of the main disadvantages is that they require a high level of self-discipline and motivation. Without the structure and accountability of a traditional classroom environment, it can be easy for students to procrastinate or fall behind in their studies. Online courses also require students to have good time management skills in order to balance their studies with their other commitments.Another disadvantage of online courses is that they can be less interactive than traditional classroom-based courses. While online courses often include discussion forums and other forms of communication, they do not offer the same level of face-to-face interaction as traditional courses. This can make it more difficult for students to build relationships with their classmates and instructors, and it can also make it more difficult for students to get immediate feedback on their work.In addition, online courses may not be suitable for all types of learners. Some students may prefer the structure and accountability of a traditional classroom environment, while others may find it difficult to learn independently. Online courses also require students to have a certain level of technical proficiency in order to access and navigate the course materials.Online courses offer a convenient and flexible way for people to learn, and they have many advantages over traditional classroom-based courses. However, like any other form of education, online courses also have some disadvantages. It is important for students to carefully consider their learning style and needs before deciding whether to take an online course or a traditional classroom-based course.。

讲义与教案有什么不同吗英文作文Title: The Differences between Lecture Notes and Lesson PlansIntroduction:In the field of education, both lecture notes and lesson plans play crucial roles in facilitating effective teaching and learning. While they share similarities in terms of content coverage, their structures, formats, and purposes differ significantly. This article aims to explore the distinctions between lecture notes and lesson plans.I. Definition and Purpose- Lecture Notes:- Definition: Lecture notes are written or typed records of key points, explanations, and examples used by teachers during a lecture or presentation.- Purpose: Lecture notes serve as a reference for the instructor to deliver information, explanations, and observations to students. They can also be used as a revision resource for students after the lecture.- Lesson Plans:- Definition: Lesson plans are comprehensive documents outlining the objectives, teaching strategies, learning activities, resources, and assessments for a specific lesson or unit.- Purpose: Lesson plans provide a systematic framework for teachers to organize and deliver effective instruction. They ensure that learningobjectives are addressed and guide teachers in selecting relevant teaching strategies, activities, and assessments.II. Structure and Components- Lecture Notes:- Structure: Lecture notes are usually presented in a linear format, following the sequence of the lecture.- Components: They often consist of headings, subheadings, bullet points, and illustrations. They may also include references to additional materials or resources.- Lesson Plans:- Structure: Lesson plans typically have a standardized structure, including sections such as objectives, introduction, instructional strategies, assessment methods, and closure.- Components: They encompass detailed descriptions of activities, timing, resources, assessment criteria, and differentiation strategies to address diverse student needs.III. Focus and Detail- Lecture Notes:- Focus: Lecture notes focus primarily on the instructor's delivery of content and explanations, often reflecting the instructor's expertise and preferred teaching style.- Detail: They tend to provide condensed information, main ideas, and key examples without extensive elaboration or step-by-step instructions.- Lesson Plans:- Focus: Lesson plans place equal emphasis on the instructor's facilitation and the students' active engagement in learning.- Detail: They entail step-by-step procedures, including instructions for each activity, prompts, questions, and possible student responses. They also incorporate differentiation strategies to accommodate various learning needs.Conclusion:In summary, lecture notes and lesson plans are distinct but complementary instructional tools. Lecture notes primarily support the delivery of information, while lesson plans encompass a wider range of elements essential for planning and executing effective lessons. Both resources contribute to fostering meaningful learning experiences, and educators should ensure coherence between the two when preparing for instruction.。

(40 points)2001年英语试题第3页(共14页)Text 1Specialization can be seen as a response to the problem of an increasing accumulation of scientific knowledge. By splitting up the subject matter into smaller units, one man could continue to handle the information and use it as the basis for further research. But specialization was only one of a series of related developments in science affecting the process of communication. Another was the growing professionalisation of scientific activity.No clear-cut distinction can be drawn between professionals and amateurs in science: exceptions can be found to any rule. Nevertheless, the word “amateur” does carry a connotation that the person concerned is not fully integrated into the scientific community and, in particular, may not fully share its values. The growth of specialization in the nineteenth century, with its consequent requirement of a longer, more complex training, implied greater problems for amateur participation in science. The trend was naturally most obvious in those areas of science based especially on a mathematical or laboratory training, and can be illustrated in terms of the development of geology in the United Kingdom.A comparison of British geological publications over the last century and a half reveals not simply an increasing emphasis on the primacy of research, but also a changing definition of what constitutes an acceptable research paper. Thus, in the nineteenth century, local geological studies represented worthwhile research in their own right; but, in the twentieth century, local studies have increasingly become acceptable to professionals only if they incorporate, and reflect on, the wider geological picture. Amateurs, on the other hand, have continued to pursue local studies in the old way. The overall result has been to make entrance to professional geological journals harder for amateurs, a result that has been reinforced by the widespread introduction of refereeing, first by national journals in the nineteenth century and then by several local geological journals in the twentieth century. As a logical consequence of this development, separate journals have now appeared aimed mainly towards either professional or amateur readership. A rather similar process of differentiation has led to professional geologists coming together nationally within one or two specific societies, whereas the amateurs have tended either to remain in local societies or to come together nationally in a different way.2001年英语试题第4页(共14页)Although the process of professionalisation and specialization was already well under way in British geology during the nineteenth century, its full consequences were thus delayed until the twentieth century. In science generally, however, the nineteenth century must be reckoned as the crucial period for this change in the structure of science.51. The growth of specialization in the 19th century might be more clearly seen in sciencessuch as ________.[A] sociology and chemistry [B] physics and psychology[C] sociology and psychology [D] physics and chemistry52. We can infer from the passage that ________.[A] there is little distinction between specialization and professionalisation[B] amateurs can compete with professionals in some areas of science[C] professionals tend to welcome amateurs into the scientific community[D] amateurs have national academic societies but no local ones53. The author writes of the development of geology to demonstrate ________.[A] the process of specialization and professionalisation[B] the hardship of amateurs in scientific study[C] the change of policies in scientific publications[D] the discrimination of professionals against amateurs54. The direct reason for specialization is ________.[A] the development in communication[B] the growth of professionalisation[C] the expansion of scientific knowledge[D] the splitting up of academic societiesText 2A great deal of attention is being paid today to the so-called digital divide -- the division of the world into the info (information) rich and the info poor. And that divide does exist today. My wife and I lectured about this looming danger twenty years ago. What was less visible then,2001年英语试题第5页(共14页)however, were the new, positive forces that work against the digital divide. There are reasons to be optimistic.There are technological reasons to hope the digital divide will narrow. As the Internet becomes more and more commercialized, it is in the interest of business to universalize access — after all, the more people online, the more potential customers there are. More and more governments, afraid their countries will be left behind, want to spread Internet access. Within the next decade or two, one to two billion people on the planet will be netted together. As a result, I now believe the digital divide will narrow rather than widen in the years ahead. And that is very good news because the Internet may well be the most powerful tool for combating world poverty that we’ve ever had.Of course, the use of the Internet isn’t the only way to defeat poverty. And the Internet is not the only tool we have. But it has enormous potential.To take advantage of this tool, some impoverished countries will have to get over their outdated anti-colonial prejudices with respect to foreign investment. Countries that still think foreign investment is an invasion of their sovereignty might well study the history of infrastructure (the basic structural foundations of a society) in the United States. When the United States built its industrial infrastructure, it didn’t have the capital to do so. And that is why America’s Second Wave infrastructure -- including roads, harbors, highways, ports and so on — were built with foreign investment. The English, the Germans, the Dutch and the French were investing in Britain’s former colony. They financed them. Immigrant Americans built them. Guess who owns them now? The Americans. I believe the same thing would be true in places like Brazil or anywhere else for that matter. The more foreign capital you have helping you build your Third Wave infrastructure, which today is an electronic infrastructure, the better off you’re going to be. That doesn’t mean lying down and becoming fooled, or letting foreign corporations run uncontrolled. But it does mean recognizing how important they can be in building the energy and telecom infrastructures needed to take full advantage of the Internet.55. Digital divide is something ________.[A] getting worse because of the Internet2001年英语试题第6页(共14页)[B] the rich countries are responsible for[C] the world must guard against[D] considered positive today56. Governments attach importance to the Internet because it ________.[A] offers economic potentials[B] can bring foreign funds[C] can soon wipe out world poverty[D] connects people all over the world57. The writer mentioned the case of the United States to justify the policy of ________.[A] providing financial support overseas[B] preventing foreign capital’s control[C] building industrial infrastructure[D] accepting foreign investment58. It seems that now a country’s economy depends much on ________.[A] how well-developed it is electronically[B] whether it is prejudiced against immigrants[C] whether it adopts America’s industrial pattern[D] how much control it has over foreign corporationsText 3Why do so many Americans distrust what they read in their newspapers? The American Society of Newspaper Editors is trying to answer this painful question. The organization is deep into a long self-analysis known as the journalism credibility project.Sad to say, this project has turned out to be mostly low-level findings about factual errors and spelling and grammar mistakes, combined with lots of head-scratching puzzlement about what in the world those readers really want.But the sources of distrust go way deeper. Most journalists learn to see the world through a set of standard templates (patterns) into which they plug each day’s events. In other words, there is a conventional story line in the newsroom culture that provides a backbone and a ready-made2001年英语试题第7页(共14页)narrative structure for otherwise confusing news.There exists a social and cultural disconnect between journalists and their readers, which helps explain why the “standard templates” of the newsroom seem alien to many readers. In a recent survey, questionnaires were sent to reporters in five middle-size cities around the country, plus one large metropolitan area. Then residents in these communities were phoned at random and asked the same questions.Replies show that compared with other Americans, journalists are more likely to live in upscale neighborhoods, have maids, own Mercedeses, and trade stocks, and they’re less likely to go to church, do volunteer work, or put down roots in a community.Reporters tend to be part of a broadly defined social and cultural elite, so their work tends to reflect the conventional values of this elite. The astonishing distrust of the news media isn’t rooted in inaccuracy or poor reportorial skills but in the daily clash of world views between reporters and their readers.This is an explosive situation for any industry, particularly a declining one. Here is a troubled business that keeps hiring employees whose attitudes vastly annoy the customers. Then it sponsors lots of symposiums and a credibility project dedicated to wondering why customers are annoyed and fleeing in large numbers. But it never seems to get around to noticing the cultural and class biases that so many former buyers are complaining about. If it did, it would open up its diversity program, now focused narrowly on race and gender, and look for reporters who differ broadly by outlook, values, education, and class.59. What is the passage mainly about?[A] needs of the readers all over the world[B] causes of the public disappointment about newspapers[C] origins of the declining newspaper industry[D] aims of a journalism credibility project60. The results of the journalism credibility project turned out to be ________.[A] quite trustworthy [B] somewhat contradictory[C] very illuminating [D] rather superficial2001年英语试题第8页(共14页)61. The basic problem of journalists as pointed out by the writer lies in their ________.[A] working attitude [B] conventional lifestyle[D] educational background[C] world outlook62. Despite its efforts, the newspaper industry still cannot satisfy the readers owing to its________.[A] failure to realize its real problem[B] tendency to hire annoying reporters[C] likeliness to do inaccurate reporting[D] prejudice in matters of race and genderText 4The world is going through the biggest wave of mergers and acquisitions ever witnessed. The process sweeps from hyperactive America to Europe and reaches the emerging countries with unsurpassed might. Many in these countries are looking at this process and worrying: “Won’t the wave of business concentration turn into an uncontrollable anti-competitive force?”There’s no question that the big are getting bigger and more powerful. Multinational corporations accounted for less than 20% of international trade in 1982. Today the figure is more than 25% and growing rapidly. International affiliates account for a fast-growing segment of production in economies that open up and welcome foreign investment. In Argentina, for instance, after the reforms of the early 1990s, multinationals went from 43% to almost 70% of the industrial production of the 200 largest firms. This phenomenon has created serious concerns over the role of smaller economic firms, of national businessmen and over the ultimate stability of the world economy.I believe that the most important forces behind the massive M&A wave are the same that underlie the globalization process: falling transportation and communication costs, lower trade and investment barriers and enlarged markets that require enlarged operations capable of meeting customer’s demands. All these are beneficial, not detrimental, to consumers. As productivity grows, the world’s wealth increases.2001年英语试题第9页(共14页)Examples of benefits or costs of the current concentration wave are scanty. Yet it is hard to imagine that the merger of a few oil firms today could re-create the same threats to competition that were feared nearly a century ago in the U.S., when the Standard Oil Trust was broken up. The mergers of telecom companies, such as WorldCom, hardly seem to bring higher prices for consumers or a reduction in the pace of technical progress. On the contrary, the price of communications is coming down fast. In cars, too, concentration is increasing — witness Daimler and Chrysler, Renault and Nissan — but it does not appear that consumers are being hurt.Yet the fact remains that the merger movement must be watched. A few weeks ago, Alan Greenspan warned against the megamergers in the banking industry. Who is going to supervise, regulate and operate as lender of last resort with the gigantic banks that are being created? Won’t multinationals shift production from one place to another when a nation gets too strict about infringements to fair competition? And should one country take upon itself the role of “defending competition” on issues that affect many other nations, as in the U.S. vs. Microsoft case?63.

A lateral move that hurt my pride and blocked my professional progress prompted me to abandon my relatively high profile career although, in the manner of a disgraced government minister, I covered my exit by claiming “I wanted to spend more time with my family”.Curiously, some two-and-a-half years and two novels later, my experiment in what the Americans term “downshifting” has turned my tired excuse into an absolute reality. I have been transformed from a passionate advocate of the philosophy of “having it all,” preached by Linda Kelsey for the past seven years in the page of She magazine, into a woman who is happy to settle for a bit of everything.I have discovered, as perhaps Kelsey will after her much-publicized resignation from the editorship of She after a build-up of stress, that abandoning the doctrine of “juggling your life,” and making the alternative move into “downshifting” brings with it far greater rewards than financial success and social status. Nothing could persuade me to return to the kind of life Kelsey used to advocate and I once enjoyed: 12-hour working days, pressured deadlines, the fearful strain of office politics and the limitations of being a parent on “quality time”.In America, the move away from juggling to a simpler, less materialistic lifestyle is a well-established trend. Downshifting — also known in America as “voluntary simplicity” — has, ironically, even bred a new area of what might be termed anti-consumerism. There are a number of best-selling downshifting self-help books for people who want to simplify their lives; there are newsletters, such as The Tightwad Gazette, that give hundreds of thousands of Americans useful tips on anything from recycling their cling-film to making their own soap; there are even support groups for those who want to achieve the mid-’90s equivalent of dropping out.While in America the trend started as a reaction to the economic decline — after the mass redundancies caused by downsizing in the late ’80s — and is still linked to the politics of thrift, in Britain, at least among the middle-class downshifters of my acquaintance, we have different reasons for seeking to simplify our lives.2001年英语试题第11页(共14页)For the women of my generation who were urged to keep juggling through the ’80s, downshifting in the mid-’90s is not so much a search for the mythical good life — growing your own organic vegetables, and risking turning into one — as a personal recognition of your limitations.67. Which of the following is true according to Paragraph 1?[A] Full-time employment is a new international trend.[B] The writer was compelled by circumstances to leave her job.[C] “A lateral move” means stepping out of full-time employment.[D] The writer was only too eager to spend more time with her family.68. The writer’s experiment shows that downshifting ________.[A] enables her to realize her dream[B] helps her mold a new philosophy of life[C] prompts her to abandon her high social status[D] leads her to accept the doctrine of She magazine69. “Juggling one’s life” probably means living a life characterized by ________.[A] non-materialistic lifestyle[B] a bit of everything[C] extreme stress[D] anti-consumerism70. According to the passage, downshifting emerged in the U.S. as a result of ________.[A] the quick pace of modern life[B] man’s adventurous spirit[C] man’s search for mythical experiences[D] the economic situation2001年英语试题第12页(共14页)Section IV English-Chinese TranslationDirections:Read the following passage carefully and then translate the underlined sentences into Chinese. Your translation must be written neatly on ANSWER SHEET 2. (15 points) In less than 30 years’ time the Star Trek holodeck will be a reality. Direct links between the brain’s nervous system and a computer will also create full sensory virtual environments, allowing virtual vacations like those in the film Total Recall.71) There will be television chat shows hosted by robots, and cars with pollution monitors that will disable them when they offend. 72) Children will play with dolls equipped with personality chips, computers with in-built personalities will be regarded as workmates rather than tools, relaxation will be in front of smell-television, and digital age will have arrived.According to BT’s futurologist, Ian Pearson, these are among the developments scheduled for the first few decades of the new millennium (a period of 1,000 years), when supercomputers will dramatically accelerate progress in all areas of life.73) Pearson has pieced together the work of hundreds of researchers around the world to produce a unique millennium technology calendar that gives the latest dates when we can expect hundreds of key breakthroughs and discoveries to take place. Some of the biggest developments will be in medicine, including an extended life expectancy and dozens of artificial organs coming into use between now and 2040.Pearson also predicts a breakthrough in computer-human links. “By linking directly to our nervous system, computers could pick up what we feel and, hopefully, simulate feeling too so that we can start to develop full sensory environments, rather like the holidays in Total Recall or the Star Trek holodeck,” he says. 74) But that, Pearson points out, is only the start of man-machine integration: “It will be the beginning of the long process of integration that will ultimately lead to a fully electronic human before the end of the next century.”2001年英语试题第13页(共14页)Through his research, Pearson is able to put dates to most of the breakthroughs that can be predicted. However, there are still no forecasts for when faster-than-light travel will be available, or when human cloning will be perfected, or when time travel will be possible. But he does expect social problems as a result of technological advances. A boom in neighborhood surveillance cameras will, for example, cause problems in 2010, while the arrival of synthetic lifelike robots will mean people may not be able to distinguish between their human friends and the droids. 75) And home appliances will also become so smart that controlling and operating them will result in the breakout of a new psychological disorder — kitchen rage.Section V Writing76.Directions:Among all the worthy feelings of mankind, love is probably the noblest, but everyone has his/her own understanding of it.There has been a discussion recently on the issue in a newspaper.
