m in Intemet-based instruction. In just a fewyears,34 percent ofAmerican universities have begun offering some form. ofdistance learning (DL), and among the larger schools,its closer to 90 percent.If you doubt the popularity of the trend, you probably havent heard of theUniversity ofPhoenix. It grants degrees entirely on the basis of onlineinstruction. It enrolls 90,000 students, a statistic used tosupport its claimto be the largest private university in the country. Whilethe kinds of instruction offered in these programs will differ, DL usuallysignifies a course in which theinstructors post syllabi(课程大纲), reading assignments, and schedules on Websites, and students sendin theirassignments by e-mail. Generally speaking, face-to-face communicationwith an instructor is minimized oreliminated altogether. Theattraction for students might at first seem obvious. Primarily, theres theconvenience promised by courseson the Net: you can do the work, as they say, inyour pajamas (睡衣). But figures indicate that the reducedeffortresults in a reduced commitment to the course. While dropout rates for allfreshmen at American universitiesis around 20 percent, the rate for onlinestudents is 35 percent. Students themselves seem to understand theweaknessesinherent in the setup. In a survey conducted for eComell, the DL division ofComell University, lessthan a third of the respondents expected the quality ofthe online course to be as good as the classroom course. Clearly,from the schools perspective, theres a lot of money to be saved. Althoughsome of the moreambitious programs require new investments in servers andnetworks to support collaborative software, most DLcourses can run on existingor minimally upgraded(升级)systems. The more students who enroll in acourse butdont come to campus, the more the school saves on keeping the lightson in the classrooms, paying doorkeepers,and maintaining parking lots. Andtheres evidence that instructors must work harder to run a DL course foravariety of reasons, they wont be paid any more, and might well be paid less. What is the most striking feature of theUniversity of Phoenix？

A.Allits courses are offered online.

B.Itsonline courses are of the best quality.

C.It boasts the largest number of studentson campus.

D.Anyone taking its online courses is sure to get a degree.

dont yet know about them, one thing they do agree on is that what kids use and expect from their world has changed rapidly. And its all because of technology. To the psychologists, sociologists, and generational and media experts who study them, their digital gear sets this new group apart, even from their tech-savvy (懂技术的) Millennial elders. They want to be constantly connected and available in a way even their older siblings dont quite get. These differences may appear slight, but they signal an all-encompassing sensibility that some say marks the dawning of a new generation. The contrast between Millennials and this younger group was so evident to psychologist Larry Rosen of California State University that he has declared the birth of a new generation in a new book, Rewired: Understanding the iGeneration and the Way They Learn, out next month. Rosen says the tech-dominated life experience of those born since the early 1990s is so different from the Millennials he wrote about in his 2007 book, Me, MySpace and I: Parenting the Net Generation, that they warrant the distinction of a new generation, which he has dubbed the "iGeneration". "The technology is the easiest way to see it, but its also a mind-set, and the mind-set goes with the little ‘i, which Im talking to stand for individualized," Rosen says. "Everything is defined and individualized to ‘me. My music choices are defined to me. What I watch on TV any instant is defined to ‘me. " He says the iGeneration includes todays teens and middle-schoolers, but its too soon to tell about elementary-school ages and younger. Rosen says the iGeneration believes anything is possible. "If they can think of it, somebody probably has or will invent it," he says. "They expect innovation." They have high expectations that whatever they want or can use "will be able to be tailored to their own needs and wishes and desires." Rosen says portability is key. They are inseparable from their wireless devices, which allow them to text as well as talk, so they can be constantly connected-even in class, where cellphones are supposedly banned. Many researchers are trying t6 determine whether technology somehow causes the brains of young people to be wired differently. "They should be distracted and should perform. more poorly than they do," Rosen says. "But findings show teens survive distractions much better than we would predict by their age and their brain development. " Because these kids are more immersed and at younger ages, Rosen says, the educational system has to change significantly. "The growth curve on the use of technology with children is exponential(指数的), and we run the risk of being out of step with this generation as far as how they learn and how they think," Rosen says. "We have to give them options because they want their world individualized. " Compared with their Millennial elders, the iGeneration kids

A.communicate with others by high-tech methods continually

B.prefer to live a virtual life than a real one

C.are equipped with more modem digital techniques

D.know more on technology than their elders

round the world -- GM, Wal-Mart, IBM, etc. they all have one thing in common: loyal custom-ers. It can cost ten to twenty times as much to ac-quire a customer as to retain one, so its easy to understand why Customer Relationship Manage-ment is such a hot concept. But, while everyone understands CRM is a good thing, putting a CRM strategy together isnt easy. The place to start？ A customer -- driven business model. A．customer-driven business model is the most prudent method of ensuring customer loyalty because it fosters a better relationship with new and existing customers. Others such as market, price, cost or e-commerce-driven business models may generate profits, but fall short of sustaining a loyal customer base. At the heart of customer- driven business model is a clear understanding of the customer-not just customer trends (although this is useful information, too), but the buying habits and history of every one of your customers. This 360-degree view provides analytics from multiple channels (direct, web, fax, E-mail, call center, sales/marketing) and consolidates into a common repository. Monitoring buying habits and tracking market dynamics lets you more effectively market new and existing products and services. If you think this is a daunting task, you arent alone. Because most enterprises dont have a consolidated view of their customers, obtaining customer profit and cost information is often a herculean effort. Implementing a CRM solution is usually a huge project with a high probability of failure. Some analysts suggest most businesses underestimate the cost of a CRM implementation by 40-75 percent. In fact, a successful CRM will interface with ERP systems to provide integration with all customer interactions such as order processing, billing. Also, CRM strategies must include commitment and sponsorship from senior management, as it should be deemed a strategic investment that is implemented incrementally and evolutionarily. Understanding critical success factors, such as those listed in the " Key to CRM Success" sidebar, mitigates the risks. First, start with a cultural change that focuses on a customer-centric business strategy. Make sure your organization is well aware of the high cost of customer attrition and is focused on improving retention, increasing loyalty. Understanding and broadcasting the cost of acquiring new customers versus fostering existing relationships. Second, focus on an enterprise view of the customer that encompasses all customer data, such as communication history, purchasing behaviours, channel preferences, demographics, etc. Understand your customers preferred channels and determine if theres some way to optimize them. Adopt a flexible architecture that will expand with your business -- this is tree with any IT project. Never deploy a strategic, costly solution using the big-bang approach. Always take an increment, evolutionary, or iterative approach. The impact to your organization can be significant, thus, proceed slowly and ensure the returns on investment measures are in nlze. The first paragraph indicates that loyal customers

A.help reduce costs of the company．

B.are quite common around the world．

of debt. the conversation is almost always about student loan debt. But theres a growing body of evidence suggesting that todays young adults are also drowning in credit-card debt—and that many of them will take this debt to their graves. More than 20% overspent their income by more than $ 100 every single month. Since they havent built up their credit histories yet. its a safe bet that these young adults are paying relatively high interest rates on the resulting credit card debt. Although many young people blame "socializing" as a barrier to saving money, most of them arent knocking back $20 drinks in trendy(时尚的)lounges. Theyre struggling with much more daily financial demands. To a disturbingly large extent, the young and the broke are relying on credit cards to make it until their next payday. This obviously isnt sustainable in the long run. and its going to put a huge drag on their spending power even after they reach their peak earning years, because theyll still be paying interest on that bottle of orange juice or box of spaghetti(意式面条)they bought a decade earlier. A new study out of Ohio State University found that young adults are accumulating credit card debt at a more rapid rate than other age groups, and that theyre slower at paying it off. " If what we found continues to hold true, we may have more elderly people with substantial financial problems in the future." warns Lucia Dunn, professor of economics at Ohio State. "If our findings persist, we may be faced with a financial crisis among elderly people who cant pay off their credit cards. " Dunn says a lot of these young people are never going to get out from under their credit card debt. "Many people are borrowing on credit cards so heavily that payoff rates at these levels are not sufficient to recover their credit card debt by the end of their life, which could have loss implications for the credit card issuing banks."

What is the main idea of the first paragraph？

A．Many young Americans will never be able to pay off their debts.

B．Credit cards play an increasingly important role in college life.

C．Credit cards are doing more harm than student loans.

D．The American credit card system is under criticism.

A Mess on theLadder of Success

A) Throughout Americanhistory there has almost always been at least one central economic narrativethatgave the ambitious or unsatisfied reason to pack up and seek their fortuneelsewhere. For the first 300or so years of European settlement, the story wasabout moving outward: getting immigrants to thecontinent and then to thefrontier to clear the prairies (大草原), drain thewetlands and build new cities.

B) By the end of the 19thcentury, as the frontier vanished, the US had a mild panic attack. What wouldthisenergetic, enterprising country be without new lands to conquer？ Some people,such as Teddy Roosevelt, decided to keep on conquering (Cuba, the Philippines,etc.), but eventually, in industrialization, the US found a new narrative ofeconomic mobility at home. From the 1890s to the

1960s,people moved from farm to city, first in the North and then in the South. Infact, by the 1950s,there was enough prosperity and white-collar work that manybegan to move to the suburbs. As the population aged, there was also a shift from the cold Rust Belt to the comforts of the Sun Belt, Wethink of this as anold persons migration, but it created many jobs for the young in coustructionand health care, not to mention tourism, retail and restaurants.

C) For the last 20 years-from the end of the coldwar through two burst bubbles in a single decade--theUS has been casting aboutfor its next economic narrative. And now it is experienc.ing another periodofpanic, which is bad news for much of the workforce but particularly for itsyoungest members.

D) The US has always been a remarkably mobilecountry, but new data from the Census Bureau indicatethat mobility has reachedits lowest level in recorded history. Sure, some people are stuck in homesvaluedat less than their mortgages (抵押贷款), but many youngpeople,-who dont own homes anddont yet have famihes--are staying put, too.This suggests, among other things, that people arentpacking up for neweconomic opportmtities the way they used to. Rather than dividing the countryintothe 1 percenters versus (与……相对) everyone else, the split in our economy is really between twootherclasses: the mobile and immobile.

E) Part of the problem is that the countryslargest industries are in decline. In the past, it was perfectlyclear whereyoung people should go for work (Chicago in the 1870s, Detroit in the 1910s,Houston inthe 1970s) and, more or less, what theyd be doing when they gotthere (killing cattle, building cars,~selling oil). And these industries werelarge enough to offer jobs to each class of worker, fromunskilled laborer tomanager or engineer. Today, the few bright spots in our economy are relativelysmall (though some promise future growth) and decentralized. There are greatjobs in Silicon Valley, in the biotech research capitals of Boston andRaleigh-Durham and in advanced manufacturing plantsalong the southern 1-85corridor. These companies recruit all over the country and the globe forworkerswith specific abilities.(You dont need to be the next Mark Zuckerberg, founderofFacebook, to get a job in one of the microhubs (微中心), by the way. But youwill almost certainlyneed at least a B, A. in computer science or a year or twoat a technical school.) This newer, select job market is national, and itoffers members of the mobile class competitive salaries and higherbargainingpower.

F) Many members of the immobile class, on theother hand, live in the America of the gloomy headlines.If you have nospecialized skills, theres little reason to uproot to another state and be thelast in linefor a low-paying job at a new auto plant or a green-energy startup.The surprise in the census (普查)data, however, is that the immobile workforce is not limited tounskilled workers. In fact, many have a college degree.

G) Until now, a B.A. in any subject was a near-guarantee of at least middle-class wages.But today, aquarter of college graduates make less than the typical workerwithout a bachelors degree. David Autor, a prominent labor economist at M. I.T., recently told me that a college degree alone is nolonger a guarantor of agood job. While graduates from top universities are still likely to get a goodjobno matter what their major is, he said, graduates from less-famous schoolsare going to be judged onwhat they know. To compete for jobs on a nationallevel, they should be armed with the skills thatemerging industries need,whether technical or not.

H) Thosewithout such specialized skills--like poetry, or even history, majors--arealready competing with their neighbors for the same sorts of second-rate,poorer-paying local jobs like low-levelmanagement or big-box retail sales. Andwith the low-skilled labor market atomized into thousands ofmicroeconomies,immobile workers are less able to demand better wages or conditious or toacquire valuable skills.

I) Sowhat, exactly, should the ambitious young worker of today be learning？Unfortunately, its hard tosay, since the US doesnt have one clear nationalproject. There are plenty of emerging, smaller industries, but which ones arethe most promising？ (Nanotechnologys (纳米技术) moment of remarkable growth seems to havebeen 5 years into the future for something like 20 years now.) Itsnot clearexactly what skills are most needed or if they will even be valuable in adecade.

J) Whatis clear is that all sorts of government issueseducation, health-insuranceportability, worker retraining--are no longer just bonuses to alreadyprosperous lives but existential requirements. Its inall of our interests tomake sure that as many people as possible are able to move toward opportunity,and, Americas ability to invest people and money in exciting new ideas isstill greater than that of most other wealthy countries. (As recently as fiveyears ago, US migration was twice the rate of EuropeanUnion states.) That, atleast, is some comfort at a time when our national economy seems to besearchingfor its next story line.

Unlike in the past, a college degree alone does not guarantee a good job for its holder.

The census data is surprising in that college graduates are also among the immobile workforce.

New figures released by the government show that Americans today are less mobile than ever before.

The migration of old people from cold to warm places made many jobs available to the young.

America is better at innovation than most other rich nations.

Early American history is one of moving outward.

Young people dont know what to learn because it is hard to predict what skills are most needed orvalued ten years from now.

Computer or other technical skills are needed to get a well-paying job in high-tech, or advancedmanufacturing.

When the frontier vanished about a century ago, America found new economic mobility inindustrialization.

America today can be divided into two classes., those who move and those who dont.

ity fraud are terms used to refer to all types of crime in which someone wrongfullyobtains and uses another persons personal data in some way that involves fraud or deception, typically foreconomic gain. B）The numbers associated with identity theft are beginning to add up fast these days. A recent GeneralAccounting Office report estimates that as many as 750,000 Americans are victims of identity theft every year.And that number may be low, as many people choose not to report the crime even if they know they have beenvictimized: C）Identity theft is "an absolute epidemic", states Robert Ellis Smith, a respected author and advocate of privacy,"Its certainly picked up in the last four or five years. Its worldwide. It affects everybody, and theres very littleyou can do to prevent it and, worst of all, you cant detect it until its probably too late." D）Unlike your fingerprints, which are unique to you and cannot be given to someone else for their use, yourpersonal data, especially your social security number, your bank account or credit card number, your telephonecalling card number, and other valuable identifying data, can be used, if they fall into the wrong hands, topersonally profit at your expense. In the United States and Canada, for example, many people have reportedthat unauthorized persons have taken funds out of their bank or financial accounts, or, in the worst cases, taken over their identities altogether, rtmning up vast debts and committing crimes while using the victims names. Inmany cases, a victims losses may include not only out-of-pocket financial losses, but substantial additionalfinancial costs associated with trying to restore his reputation in the community and correcting erroneousinformation for which the criminal is responsible. E） According to the FBI, identity theft is the number one fraud committed on the Internet. So how do job seekersprotect themselves while continuing to circulate their resumes online？ The key to a successful online jobsearch is learning to manage the risks. Here are some tips for staying safe while conducting a job search on theInternet. F）Check for a privacy policy. If you are considering posting your resume online, make sure the job search siteyou are considering has a privacy policy, like CareerBuilder.com. The policy should spell out how yourinformation will be used, stored and whether or not it will be shared. You may want to think twice aboutposting your resume on a site that automatically shares your information with others. You could be openingyourself up to unwanted calls from solicitors (推销员). When reviewing the sites privacy policy, youll be ableto delete your resume just as easily as you posted it. You wont necessarily want your resume to remain outthere on the Internet once you land a job. Remember, the longer your resume remains posted on a job board,the more exposure, both positive and not-so-positive, it will receive. G）Take advantages of site features. Lawful job search sites offer levels of privacy protection. Before posting yourresume, carefully consider your job search objectives and the level of risk you are willing to assume.CareerBuilder.com, for example, offers three levels of privacy from which job seekers can choose. The first isstandard posting. This option gives job seekers who post their resumes the most visibility to the broadestemployer audience possible. The second is anonymous(匿名的) posting. This allows job seekers the samevisibility as those in the standard posting category without any of their contact information being displayed.Job seekers who wish to remain anonymous but want to share some other information may choose whichpieces of contact information to display. The third is private posting. This option allows a job seeker to post aresume without having it searched by employers. Private posting allows job seekers to quickly and easily applyfor jobs that appear on CareerBuilder.com without retyping their information. H）Safeguard your identity. Career experts say that one of the ways job seekers can stay safe while using theIntemet to search out jobs is to conceal their identities. Replace your name on your resume with a generic (泛指的) identifier, such as "Intranet Developer Candidate", or "Experienced Marketing Representative". Youshould also consider eliminating the name and location of your current employer. Depending on your title, itmay not be all that difficult to determine who you are once the name of your company is provided. Use ageneral description of the company such as "Major auto manufacturer," or "international packaged goodssupplier." If your job title is unique, consider using the generic equivalent instead of the exact title assigned byyour employer. I）Establish an email address for your search. Another way to protect your privacy while seeking employmentonline is to open up an email account specifically for your online job search. This will safeguard your existingemail box in the event someone you dont know gets hold of your email address and shares it with others.Using an email address specifically for your job search also eliminates the possibility that you will receiveunwelcome emails in your primary mailbox. When naming your new email address, be sure that it doesntcontain references to your name or other information that will give away your identity. The best solution is anemail address that is relevant to the job you are seeking such as salesmgr2004@provider.com. J）Protect your references. If your resume contains a section with the names and contact information of yourreferences, take it out. Theres no sense in safeguarding your information while sharing private contactinformation of your references. K）Keep confidential (机密的) information confidential. Do not, under any circumstances, share your social security, drivers license, and bank account numbers or other personal information, such as race or eye color.Honest employers do not need this information with an initial application. Dont provide this even if they saythey need it in order to conduct a background check. This is one of the oldest tricks in the book--dont fallfor it. Those who post their resumes online for a long time will run an increased risk of becoming victims of identity theft.
