There are various ways in which individual economic units can interact with one another. Three basic ways may be described as the market system, the administered system, and the traditional system.
In a market system individual economic units are free to interact among each other in the marketplace. It is possible to buy commodities from other economic units or sell commodities to them. In a market, transactions may take place via barter or money exchange. In a barter economy, real goods such as automobiles, shoes, and pizzas are traded against each other. Obviously, finding somebody who wants to trade my old car in exchange for a sailboat may not always be an easy task. Hence, the introduction of money as a medium of exchange eases transactions considerably. In the modern market economy, goods and services are bought or sold for money.
An alternative to the market system is administrative control by some agency over all transactions. This agency will issue commands as to how much of each good and service should be produced, exchanged, and consumed by each economic unit. Central planning may be one way of administering such an economy. The central plan, drawn up by the government, shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. This is an example of complete planning of production, consumption, and exchange for the whole economy.
In a traditional society, production and consumption patterns are governed by tradition; every person’s place within the economic system is fixed by parentage, religion, and custom. Transactions take place on the basis of tradition, too. People belonging to a certain group or caste（阶级） may have an obligation to care for other persons, provide them with food and shelter, care for their health, and provide for their education. Clearly, in a system where every decision is made on the basis of tradition alone, progress may be difficult to achieve. An inactive society may result.What is the main purpose of the passage?
| A．To outline contrasting types of economic systems. |
| B．To explain the science of economics. |
| C．To argue for the superiority of one economic system. |
| D．To compare barter and money-exchange markets. |

It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is actually worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect" - holding in heat reflected from the earth and raising the world's average temperature. If this view is correct and the world's temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate (废气排往空中而形成的微粒、颗粒) matter in the atmosphere is blocking sunlight and lowering the earth's temperature ─ a result that would be equally disastrous. A drop of just a few degrees could create something close to new ice age and would make agriculture difficult or impossible in many of our top farming areas. At present we do not know for sure that either of these conditions will happen (though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we are very lucky, the two tendencies will offset each other and the world's temperature will stay about the same as it is now.As pointed out at the beginning of the passage, people used to think that air pollution ______.

When you are little, the whole world feels like a big playground. I was living in Conyers, Georgia the summer it all happened. I was a second grader, but my best friend Stephanie was only in the first grade. Both of our parents were at work and most of the time they let us go our own way.
It was a hot afternoon and we decided to have an adventure in Stephanie’s basement. As I opened the basement door, before us lay the biggest room, full of amazing things like guns, dolls, and old clothes. I ran downstairs, and spotted red steel can. It was paint. I looked beyond it and there lay even more paint in bright colors like purple, orange, blue and green.
“Stephanie, I just found us a project for the day. Get some paintbrushes. We are fixing to paint.” She screamed with excitement as I told her of my secret plans and immediately we got to work. We gathered all the brushes we could find and moved all of our materials to my yard. There on the road in front of my house, we painted bit stripes (条纹) of colors across the pavement (人行道). Stripe by stripe, our colors turned into a beautiful rainbow. It was fantastic!
The sun was starting to sink. I saw a car in the distance and jumped up as I recognized the car. It was my mother. I couldn’t wait to show her my masterpiece. The car pulled slowly into the driveway and from the look on my mother’s face, I could tell that I was in deep trouble.
My mother shut the car door and walked towards me. Her eyes glaring, she shouted, “What in the world were you thinking? I unde
rstood when you made castles out of leaves, and climbed the neighbors’ trees, but this! Come inside right now!” I stood there glaring hack at her for a minute, angry because she had insulted (侮辱) my art.
“Now go clean it up!” Mother and I began cleaning the road. Tears ran down my cheeks as I saw my beautiful rainbow turn into black cement.
Though years have now passed, I still wonder where my rainbow has gone. I wonder if, maybe when I get older, I can find my rainbow and never have to brush it away. I guess we all need sort of rainbow to brighten our lives from time to time and to keep our hopes and dreams colorful. What did the writer want to do when his mother came home?
| A．To introduce Stephanie to her. |

| C．To put the materials back in the yard. |
| D．To show his artwork to her. |

Most Chinese people these days
know what it is like to have an “English teacher”, since almost all pupils study English from their third year. Usually that first English teacher will be a young and lovely lady in primary school. But my first English teacher is no other than my father. Looking back, I can see that, when I was only a little girl, he created an English environment by providing me with flashcards（识字卡），fun English- language toys and even dolls which can sing English songs! My interest in English had certainly been awakened（唤起） when I began to learn English at school. Just imagine, he went a step further and a
sked me to learn New Concept English by myself! I was confused and even angry. I could not understand why a father could be so strict with his little girl. All the same, he never gave up and he gently insisted that I follow through with his idea. At first, I read stories with tears and I actually hated them because they were too difficult for me. In the end, I came to love the funny stories and, to be honest, my father was always there with a helping hand. I am sure that my English would never have got so far without his support. And that’s why my father is not only my first English teacher but also my lifelong teacher. He is the one who awoke my interest, who gave me confidence and who offered me much needed help.Most pupils in China begin to learn English________.
