For the past 3, 000 years, when pcople thought of money they thought of cash. From buying food to settling bar tabs, day-to-day dealings involved creased paper or clinking bits of metal.Over the past decade，however ，digital payments have taken off-- tapping your plastic on a terminal or swiping a smartphone has become normal. Now this revolution is about to turn eash into an endangered specics in some rich cconomics. That will make the cconomy more efieicnt - -but it also poscs new problems that could hold the transition hostage.Countries are eliminating ceash at varying speeds. But the direction of travel is clear, and in some cases the joumey is nearly complete. In Sweden the number of retail cash transactions per person has fallen by 80% in the past ten years. Cash accounts for just 6% of purchases by value in Norway. Britain is probably four or six years behind the Nordic countries. America is perhaps a deeade behind. Outside the rich world, cash is still king. But even there its dominance is being croded. In China digital payments rose from 4% of all payments in 2012 to 34% in 2017.Cash is dying out beause of two forees. One is demand- younger consumers want payment systems that plug scamlessly into their digital lives. But equally important is that supplirs such as banks and tech firms (in developed markets) and telccoms companics (in emerging oncs) are developing fast, easy-to-use payment technologics from which they can pull data and pocket fees.There is a high cost to running the infrastructure behind the cash economy-- ATMs， vans carrying notes, tellers who acept coins. Most financial firms are keen to abandonit, or deter old-fashioned customers with hefly fees.In the main，the prospect of a cashless economy is excellent news. Cash is inefficient. In rich countries, minting， sorting， storing and distributing it is cstimated to cost about 0.5% of GDP. But that does not begin to capture the gains. When payments dematerialize, people and shops are less vulnerable to theft. Govermments can keep closer tabs on fraud or tax evasion.Digitalisation vastly expands the playground of small businesses and sole traders by enabling them to sell beyond their borders. It also creates a credit history, helping consumers borrow.Yet set against these benefts are a bundle of worries. Eleotronic payment systems may be vulnerable to technical failures power blackouts and cyber- atacks- this weck Capital One，an American bank, became the latest fim to be hacked. In a cashless economy the poor, the elderly and country folk may be left behind. And eradicating cash, an anonymous payment method, for a digital system could let govemments snoop on people's shopping habits and private titans exploit their personal data.These problems have three remedies. First, govermments need to ensure that central banks' monopoly over coins and notes is not replaced by private monopolies over digital money. Rather than ltting a few credil-card firms have a stranglehold on the eleetronic pipes for digital payments, as America may yet allow; gov emments must ensure the payments plumbing is open to a range of digital firms which can build services on top of it. They should urge banks to offer cheap,instant，bank-to-bank digital transfers between deposit accounts ，as in Sweden and the Netherlands. Competition should keep priccs low so that the poor can afford most services, and it should also mean that if one firm stumbles others can step in,. making the system resilient. Sccond, govemments should maintain banks' obligation to keep customcr information private, so that the plumbing remains anonymous. Digital firms that use this plumbing to offer services should be free to monetise transaction data, through, for example, advertising， so long as their business model is made explicit to uscrs. Some customers will favour free services that track their purchases; others will want to pay to be left alonc.Last, the phasc-out of cash should be gradual. For a period of ten years," banks should be obliged to accept and distribute cash in populated areas. This will buy govermments time to help the poor open bank accounts, educate the elderly and beef up internet access in rural areas. The rush towards digital money is the result of spontaneous demand and innovation. To pocket all the rewards, govemments need to prepare for the day when erumpled bank noles change hands for the last time.According to the article, which of the following is NOT supporting the point that“the phase-out of cash should be gradual?"A. In rural areas the intemet access still need time to be enhanced.B. The rush towards digital money should be targeting at the most beneficial results of goverment.C. It could buy govemment time for helping those impoverished people open bank accounts, and to teach elderly people Io prepare for the eleetronice payments systems.D. Banks' are obliged to offer assistance in the long process towards the final eliminating of cash.

问答题Practice 4 If ambition is to be well regarded, the rewards of ambition—wealth, distinction, control over one’s destiny—must be deemed worthy of the sacrifices made on ambition’s behalf. If the tradition of ambition is to have vitality, it must be widely shared, and it especially must be highly regarded by people who are themselves admired, the educated not least among them. In an odd way, however, it is the educated who have claimed to have given up on ambition as an ideal. What is odd is that they have perhaps most benefited from ambition, if not always their own then that of their parents and grandparents.
