[不定项选择题]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, what is the crrt method for banks and digtal firms to deal with customers' privacies? ( )
A.Banks, under the govemment's supervisions, need to fulfill the obligations of keeping customer information private.
B.Banks should cooperate with advertisement companies to sell customers' privacies for better profits.
C.Digital firms do not have to protect users' privacies as long as their business model is made explicit to users.
D.Banks should assume that all the customers are glad to enjoy firee services even their privacies are being tracked.

When Our Eyes Serve Our Stomach
Our senses aren't just delivering a strict view of what's going on in the world;they're af-fected by what's going on in our heads. A new study finds that hungry people see food-related words more clearly than people who'ye just eaten.
Psychologists have known for decades that what's going on,inside our head affects our senses. For example,poorer children think coins are larger than they are,and hungry people think pictures of food are brighter. Remi Radel of University of Nice Sophia-Antipolis,France,wanted to investi-gate how this happens. Does it happen right away as the brain receives signals from the eyes or a lit-tle later as the brain's high-level thinking processes get involved.
Radel recruited 42 students with a normal body mass index. On the day of his or her test,each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10 minutes;others were given an hour to get lunch first. So half the students were hungry when they did the ex-periment and the other half had just eaten.
For the experiment,the participant looked at a computer screen. One by one,80 words flashed on the screen for about 1/300th of a second each. They flashed at so small a size that
the students could only consciously perceive. A quarter of the words were food-related. After each word,each person was asked how bright the word was and asked to choose which of two words they'd seen一a food-related word like cake or a neutral word like boat. Each word ap-peared too briefly for the participant to really read it.
Hungry people saw the food-related words as brighter and were better at identifying food-related words. Because the word appeared too quickly for them to be reliably seen,this means that the difference is in perception,not in thinking processes,Radel says.
“This is something great to me. Humans can really perceive what they need or what they strive for. From the experiment,I know that our brain can really be at the disposal of our mo-tives and needs,”Radel says.
It can be learnt from what Radel says that______.
A.humans'thinking processes are independent of their senses
B.an experiment with hungry and non-hungry participants is not reliable
C.humans can perceive what they need without deep thinking processes
D.42 participants are too small a number for a serious investigation
