Passage Three

As a medium of exchange, money permits the separation of exchange into the two distinct acts of buying and selling. Hence producers who know they will be paid in money, can concentrate on finding the most suitable outlet for their goods, while buyers who will pay in money, can concentrate on finding the cheapest market for the wings they wish to purchase. (83) Specialization is encouraged, because people whose output is not a complete product but only a part of one can be paid an amount equivalent to their share of the product.

Another advantage of money is that it is a measure of value. In a barter economy it would be necessary to determine how many plates were worth one hundred weight of cotton, or how many pens should be exchanged for a ton of coal. (84) The process of establishing relative values would have to be undertaken for every act of exchange, according to what products were being offered against one another, and according to the two parties ’ desires and preferences.

Thirdly, money acts as store of wealth. It is difficult to imagine saving under a barter system. No one engaged on only one stage in the manufacture of a product could save part of his output, since he would be producing nothing complete. Most products deteriorate fairly rapidly, either physically or in value, as a result of long storage; even if storage were possible, the practice of storing products for years on end would involve 20 obvious disadvantages. If wealth could not be saved, or only with great difficulty, future needs could not be provided.A barter economy is one in which _______.

6.We all love a hero, and rescue dogs are some of the biggest heroes of all. You will often find themgoing above and beyond duty to save someone, risking--and at times losing--their lives in theprocess.Rescue dogs are generally found in the Sporting and Hunting Groups, or from the traditionalHerding Group. These types include the Bloodhound, Labrador Retriever, Newfoundland, GermanShepherd, Golden Retriever, and Belgian Malinois--all of which are chosen for search-and-rescueduty because of their amazing physical strength, loyalty, and their tendency for mental stability.These types also have a keen sense of hearing and smell--to better locate lost individuals—and areoften able to access hard-to-reach areas. As highly trained animals, they serve in many differentfields, including specialist search, snow slide rescue, dead body location, and tracking.To overcome obstacles and succeed when performing the demanding duties of a search-and-rescue worker, a dog must display certain qualities. In addition to intelligence and strength, thedog must be swift, confident, easily trainable, adaptable, and have a high level of stamina (耐力)and endurance.A strong sense of group cooperation and an ability to engage in friendly play during "down" timeis also required of search-and-rescue dogs.A rescue dog goes through many, many hours of intensive training to be fit for duty. Training is notfor the faint-hearted. Certification training can take from two to three years, working three to fourhours a day, three to six days a week, often in group,team-oriented sessions.Each search-and-rescue field requires different types of training. Rescue training, for instance,includes "air scenting"--where dogs are trained to smell the air for the victim' s scent (气味) andthen follow the scent to the person. This ability is crucial to finding victims trapped under collapsedbuildings and snow slide.Which ability is most important for dogs to rescue people trapped in snow?

8.The strange close understanding between twins is a familiar enough phenomenon. Often they seem to understand each other and share each other’s emotions to such an extent that one suspects some kind of thought communication.　　What is not so widely known is that this special relationship often acts as brake on twins’ intellectual development. As they are partly isolated in their own private world, twins communicate less with adults than do other children. The verbal ability of a four-year old twin is typically six months behind that of a non-twin. The problem can be particularly severe in an underprivileged family, a one parent family for example, where there is little stimulation for children anyway.　　Such children, while capable of mutual comprehension in a private language, often remain incomprehensible to outsiders and thus at a severe educational disadvantage. The only solution to the problem, cruel though it may seem, is to separate the twins thus forcing them to acquire ordinary speech helped and guided by sympathetic parents and teachers..Many people don’t know that .

9.California families are facing a rapidly mounting uphill battle to make enough money to provide basic household essentials, according to a new study conducted by the California Budget Project. 　　The research compiled by the Sacramento-based non-profit organization concluded an average two-parent family with one employed adult in California needs to make $51,177 a year, or $24.60 cents an hour, to pay for housing, transportation, food, utilities, child care, health coverage, taxes and other basic expenses. 　　The number grows significantly higher in the Bay Area, the state's most expensive region．A Bay Area family of four with two working adults living in rental housing needs a combined income of $79,946 to cover essential needs．That number is more than four times greater than the $19,157 income level recognized by the federal government as impoverished. 　　The study is the fourth semi-annual survey conducted by the California Budget Project since 1999． California Budget Project executive director Jean Ross said helping state officials and residents understand the numbers found in the report is crucial to moving families toward self-sufficiency. "How should we be targeting some of our programs and policies? How much do young people need to earn and what kind of a job should they be looking to train for if they want to have that salary that can support a family?" 　　CBP said the project was based on actual costs or generally accepted fair standard prices based on weighted averages found in ten California regions.What are some basic expenses for Bay Area families?

10.Passage ThreeAs recently as three decades ago,many Americans believed that using credit was an unwise anddangerous way to pay for what they bought.Some even thought that owing money to a store or acredit company was something to be ashamed of.Good citizens,they believed,always bought what they wanted with real money and they paid the full price immediately.Today,however,all that has changed.Credit,as some observers have noted,has become away of life in the United States.More and more Americans now are depending on those small piecesof plastic,credit cards,to pay for large purchases such as televisions,record players or furniture.Many people today would consider it unusual not to use a credit card to pay for a costly restaurant dinner,a hotel room or an airline trip.And there are some situations in which Americans must have credit cards.If they want the temporary use of a car,for example,they first must give the car rental company the number of their credit card.That number is considered a guarantee that they will returnthe car and pay for using it.Credit cards offer two major services to Americans.First of all,they are easier and safer tocarry than large amounts of money.Second,they permit people to borrow,to have the immediate pleasure of owning something,even if they do not have enough money to pay for it at the time.With credit cards people pay for goods or services at the end of each month instead of when they buy them.And when the time does come to pay,most credit cards offer people a choice.They can pay all of what they owe for the month or they can just pay usually between 5 and 10 percent of what they owe.47.What is the best title for the passage?

11.Passage FourClimate, more than any other single factor, determines the distribution of life on earth. Climatic boundaries establish the limits which organisms can survive. Plants, even more than animals, must be well adapted to climate in order to survive. They cannot move about or take shelter but must be equipped to endure whatever weather conditions are likely to occur. In the harsh conditions of the tundra, for example, low growing mosses, lichens, and a few flowering plants all hug the ground for shelter from icy winds.Animals, despite their ability to move about and find shelter, are just as much influenced by climate as plants are. Creatures such as the camel and the penguin are so highly specialized that they have an extremely limited distribution Others, such as bears are flexible enough to adapt to a broad range of climates. Oceandwelling organisms are just as sensitive to climatic changes--in this case temperature and salinity--as land animals. Reef corals can survive only in clear warm seawater. Certain foraminifers are so sensitive to changes in their environment that their presence can be taken as an index of sea temperature. Human beings are among theleast specialized of all animals and can live almost anywhere. Their clothes and their homes act as a sort of "miniature climate" that can be taken with them everywhere.According to the passage, which of the following can be found in areas with quite different climatic conditions on Earth?
