It’s difficult to think about how to spend money, and deciding money value in the future is almost impossible to many people. That’s because it is hard for us to consider the opportunity costs of objects we purchase.

A study was conducted with people who wanted to purchase a car to determine their ability to assess the opportunity cost of that purchase. When asked “If you buy this car today, what will you not be able to do in the future as a result?”, the majority said, “If I buy this SUV today, I will not be able to buy a sports car tomorrow.” Nobody said that he would not be able to buy 300 lunches at a restaurant because they were, though unconsciously, restricted within the car field, not even attempting to think of an item from another field.

The nature of modern spending makes things even harder by making money less concrete. If I give you $1,000 in an envelope each week, you will see in the shop that what you’re buying comes at the expense of other things of the same price. After all, you have the real experience because you have to hand out the real money note if you want to get the object. But with credit cards and loans, financial mechanisms have become increasingly unclear, making it more difficult for people to compare the value of spending now with the value of money in the future as they are allowed to pay for the purchases later.

Irrelevant influences and considerations, such as a person’s present emotions or preferences, can influence how much worth someone places on an object too.

In a study, Professor Dan Ariely and his team asked participants to determine the value of objects like wine, chocolates and electronics.

“We first told them to consider whether they would pay the amount equivalent to the last two digits of their social security numbers,” he says. “We found a significant relation between the amount they were willing to pay and these digits.”

For instance, someone whose social security number (SSN) ends in 25 valued the objects much lower than someone with the last two digits of 78. For no logical reasons, the test subjects leaned toward the most recent number they had access to when valuing the items. Even with full information about the objects, some people had no logical point of reference for the value of the objects. Instead, they used their own irrelevant experiences as references.

1. According to the passage, the opportunity cost in consumption field refers to ______.
A.the cost to pay for various opportunities
B.what a person is willing to give up if he buys a specific item
C.the opportunities to invest in costly items
D.the comparison of prices of the same item from different sources
2. In the test, when buying cars, most people won’t think of the alternative 300 meals because ______.
A.they won’t have trouble in paying for meals
B.300 meals are not equal to the car in value
C.they can’t compare money values across categories
D.they personally prefer the car to food
3. Purchase through credit cards makes it harder for people to recognize money value because ______.
A.items paid by credit cards are cheaper than paid by cash
B.it’s easier for people to save money through credit cards
C.people have to pay an interest when buying through credit cards.
D.delay in payment may confuse people’s judgement of money value.
4. Why were many of Dan Ariely’s test participants willing to pay the same amount as the last two digits of their social security numbers?
A.Because they were not good at predicting values and counting numbers.
B.Because they made predictions with most convenient hints available.
C.Because they believed that their SSN digits were very valuable.
D.Because they tended to consult others and copy peers’ choices.

【推荐1】Crushing disappointment

“If you want to make money in Cuba, buy garlic,” says a farmer in Artemisa province, in western Cuba. Garlic, known as “white gold” for its value, is critical to the unique seasoning of Cuban food.     1    . A lack of fertilizer and pesticide makes it especially hard to grow. And it is harvested only once a year, in January.

Every year garlic-sellers on the streets of Havana peddle bulbs from backpacks, as if selling fake luxury handbags or electronics. The price of garlic tends to boom around November and December, before more comes onto the black market. A pensioner in one part of the capital complains that a bulb now costs 25 pesos ($1) and 450g (11b) costs 240 pesos, four times the price in September.

    2    . They pay garlic farmers $50,000-100,000 to buy their whole harvest and then resell it to a network of other resellers, who in turn sell to smaller resellers and so on. The dealers make so much cash from these transactions that banks, especially the small ones out in the provinces, sometimes have to close to the public while they process the sacks of money being deposited. “You can recognize the big resellers by their cars,” sighs the farmer in Artemisa.

    3    .In 1986 Fidel Castro, then Cuba’s dictator, discovered that a garlic farmer was making $50,000 a year—ten times a local surgeon’s wage at the time— by privately selling what he had left over after meeting his quota for the state agriculture system. Outraged to see that people were behaving like “capitalists in disguise”, he closed the private farmers’ markets where it was sold.

But the pandemic has worsened shortages of basic goods in Cuba, along with fertilizers, fungicide, seeds and supplies for animals. Thousands of rabbits died last summer in an outbreak of haemorrhagic disease. Pigs may be next.     4    . Last year the government mooted eating guinea pigs, a popular food in parts of South America, but the idea was largely ridiculed. Then again, Cubans cannot live by allium alone.

A.Profiting from garlic is nothing new.
B.Another way to get the bulbs is through garlic resellers.
C.The country is on high alert following an outbreak of African swine fever in the Dominican Republic.
D.Ministry of Agriculture of Cuba has been developed a program of plant breeding with the aim of obtaining adaptation to the country conditions.
E.That is why these pensioners refuse to pay the garlic sellers on the street.
F.As with so many things on the communist island, however, it is in short supply.

【推荐2】Britain’s meat industry on Friday warned that an upcoming shortage of carbon dioxide (CO2) could cause massive disruption (中断) to food supplies within two weeks.

The gas is used to stun animals before slaughter (屠宰) , in the vacuum packing of food products to extend their shelf life, and to put the fizz into beer, cider and soft drinks. It is also required for some medical procedures and used in the nuclear and semi-conductor industries.

Britain’s food supply chain, already creaking from a severe shortage of heavy goods vehicles (HGV) drivers and the impact of Brexit (脱欧) and COVID-19, is heavily reliant on fertiliser producers for CO2 which is a by-product of their production process. However, two of the largest fertiliser producers, Norway’s Yara YAR.OL and rival CF Industries Holdings CF.N, have restrained production due to a sudden increase in natural gas prices, which has in turn started to dry up CO2 supplies.

Nick Allen, chief executive of the British Meat Processors Association (BMPA), said that once current stocks of the gas run out, some meat companies will have to stop taking animals and close production lines, leading to a logjam of animals back to the farms. “We already have this situation in the pig industry which is now facing the disruption prospect of a humane killing on farms,” he said. The BMPA is persuading Business Minister Kwasi Kwarteng to help support UK CO2 production in the short-term.

“We are monitoring this situation closely and are in regular contact with the food and farming organizations and industry, to help them manage the current situation,” said a UK government spokesperson. “The UK benefits from having access to highly diverse sources of gas supply to ensure households, businesses and heavy industry get the energy they need at a fair price. Britain last suffered a major CO2 shortage in 2018, leading to some drinks wholesalers to ration (定量) sales.”

1. What’s the direct cause of the CO2 shortage this year?
A.A government policy.B.An infectious disease.
C.Transportation failure.D.Cost rise.
2. What does the underlined word “logjam” mean in paragraph 4?
A.Bottleneck.B.Promise.
C.Setback.D.Recovery.
3. What measure may the UK government take?
A.To close production lines.B.To stop marketing animals.
C.To limit the drinks wholesale.D.To explore more gas supplies.
4. What may be the suitable title for the passage?
A.Diverse Applications of CO2B.CO2 Shortage Hit Food Supplies
C.Efforts Taken to Produce CO2D.The Future of Britain’s Meat Industry

【推荐3】You might not regard England, which is famous for its almost year round rain, as a place with a water shortage problem. However, James Bevan, head of the UK Environment Agency, warned at a recent conference that England will lack water within 25 years.

A major reason for the shortage is climate change. As recently as 2017, Britain saw its driest 10-month period in over 100 years. In 2018, below-average rainfall caused many reservoirs (水库) to run dangerously low. It’s predicted that, by 2040, over half of UK summers will be hotter than the summer of 2003, and water supply from rivers could fall by between 50-80 percent, according to CNN. In 2003, the UK experienced one of the most significant heat waves in recorded history.

Another major reason is that the British waste too much water in daily life. On average each person uses about 140 liters of water per day through a combination of showers, washing machines and garden hoses, according to the BBC. Bevan said people should try to save water and that they could cut their daily water use from 140 to 100 liters. “There re simple steps we can take... Get a low flush toilet, Take short showers...” he said during the conference.

While England may not be the only place facing a water shortage, some other areas have taken measures to avoid one. Israel, for example, recycles waste water, which makes up 40% of the country’s agricultural water.

Wherever you’re in the world, water is precious. Our world is 70% covered by water, but only 2.5% of it is fresh, and only 1% is easily accessible. So let’s try to save the water we’re lucky enough to have and not be wasteful.

1. What can be the best main idea of the passage?
A.English people are wasting too much water.
B.England may run short of water in the near future.
C.Climate change causes water shortage in England.
D.English people should solve the problem with water shortage.
2. What’s the purpose of writing the passage?
A.To call on people to save water together.
B.To educate people about the importance of water.
C.To inform people of the water problem in England.
D.To introduce ways to solve the water shortage problem.
3. Where can you probably find the article?
A.In a textbook.B.In a research report.
C.In a travel journal.D.In a newspaper.
