An important factor in a market-oriented economy is the mechanism by which consumer demands can be expressed and responded to by producers. In the American economy, this mechanism is provided by a price system, a process in which prices rise and fall in response to relative demands of consumers and supplies offered by seller-producers. If the product is in short supply relative to the demand, the price will be a bit up and some consumers will be eliminated from the market. If, on the other hand, producing more of a commodity results in reducing its cost, this will tend to increase the supply offered by seller-producers, which in turn will lower the price and permit more consumers to buy the product. Thus, price is the regulating mechanism in the American economic system.
The important factor in a private-oriented economy is that individuals are allowed to own productive resources (private property), and they are permitted to hire labor, gain control over natural resources, and produce goods and services for sale at a profit. In the American economy, the concept of private property embraces not only the ownership of productive resources but also certain rights, including the right to determine the price of a product or to make a free contract with another private individual.

What is the 'biggest city in the world? That is, (21) city has the largest population? This seems like (22) question to answer, but actually it isn't.
It's actually rather difficult to say which cities (23) the largest. There are two reasons for this difficulty. First of all, it isn't easy to determine a city's boundaries, that is, where a city ends. Nowadays, nearly all cities have a large (24) area around them. So when we talk about the population of a city, we often mean the population of the whole metropolitan area around the city. That means that it's difficult to determine what the population of a city is because it's difficult to define what a city is.
The second reason that it is difficult to 25 the population of different cities is this: it is almost impossible to get (26) about the population of all cities for the same year. For example, we might get an estimate of New York's population in 1979 and an (27) of Mexico City's population in 1981. So we real ly can't compare the numbers because the information is for (28) different years. And the population of cities changes rather quickly, especially in some cases. For example, the population of Jakarta, Indonesia, may increase by 5% each year, so the population figure will change rather quickly.
So we can say that these are our two (29) for comparing the populations of cities: one, it's difficult to determine the (30) of a city, and two, it is difficult to get accurate information.

B. which
C. where

The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster (收养) homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's IQ was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.
This selection can be titled ______.
A.Measuring Your Intelligence
B.Intelligence and Environment
C.The Case of Peter and Mark
D.how the Brain Influences Intelligence
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.
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 obvious disadvantages. If wealth could not be saved, or only with great difficulty, future needs could not be provided.
Using money as a medium of exchange means that_____.
A.you have to sell something in order to buy something
B.you have to buy something in order to sell something
C.you don’t have to buy something in order to sell something
D.the seller and the purchaser are the same person
Specialization is encouraged because_______.A.people can use their money to buy whatever they want
B.people get paid according to their share of the product.
C.people pay great attention to the manufacture of a product
D.people cannot use their money to buy whatever they want
A barter economy is one in which _______.A.value is decided by weight
B.value is decided by number
C.money is used and goods are not exchanged
D.goods are exchanged and money is not used
If one had to save products instead of money, __________.A.this would need years of practice
B.coal, for example, would lose its value
C.they could not be stored for years on end
D.many products would lose their value
How many advantages of money are mentioned in this passage?A.Two
B.Three

At picnics, ants are pests. But they have their uses. In industries such as mining, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.
It has been recognized for decades that ants—which are highly sensitive to ecological change—can provide a near-percent barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. (41) And still others will move in and take up residence.
By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. (42) Ants are used simply because they are so common and comprise so many species.
Where mine sites are being restored, for example, some ant species will recolonize the stripped land more quickly than others. (43) Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.
Ant surveys also have been used with mine-site recovery projects in Africa and Brazil, where warm climates encourage dense and diverse ant populations. "We found it worked extremely well there," says Jonathan Majer, a professor of environmental biology. Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region. As Majer puts it: "That's the great thing about ants."
Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. (44)
Why not? Because many companies can't afford the expense or the laboratory time needed to sift results for a comprehensive survey. The cost stems, also, from the scarcity of ant specialists. (45)
[A] This allowed scientists to gauge the pace and progress of the ecological recovery.
[B] Yet in other businesses, such as farming and property development, ant surveys aren't used widely.
[C] Employing those people are expensive.
[D] They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.
[E] The evolution of ant species may have a strong impact on our ecosystem.
[F] Others will die out for lack of food.
[G] Gretaceous ants shared a couple of wasp-like traits together with modern ant-like characteristics.
