Once many years ago, I pulled a family out of a burning car somewhere in Wyoming. Last week I received a telephone call from a woman who could not stop crying as she told me that one of my stories had saved her son from committing suicide. In closing she called me a hero.That got me thinking about what a hero really is. Was I a hero because I pulled a family from a burning ear If so, how could I be a hero just because I wrote a story that saved someone"s lifeToday I look up the word "hero" in the dictionary to see exactly what it meant. It read "a person who does something brave". And also "a person who is good and noble".That statement impressed me more than the part about being brave. So I thought about something very important. And I remembered what happened to me years ago.After my marriage of twenty years ended, I was in such a condition. I was within hours trying to get up enough courage to end the pain and misery. When I returned home, someone had sent me a card in the mail which told me how much they would appreciate me as a friend. That wonderful card probably saved my life. That person, without even knowing it, saved a life and became a hero.The many stories I kept writing in the following years saved the life of a teenage boy. In turn that makes the person who sent me the card a double hero. I suppose that is why I fight so hard to help the children now living in orphanages. Most children come out of these institutions with a very hard and bitter attitude against the world. The gifts we send them let them know that they have not been forgotten. Hopefully, most of them will never hurt anyone because of the kindness shown to them by those of us who cared. If it works, we will also become "heroes". What does the passage mainly discuss (No more than 10 words)

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 modem market economy, goods and services are bought or sold for money.An alternative for the market system is administrative control by some agency over all transactions. This agency will issue edicts or 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. A stagnant society may result. The author wrote this passage in order to （）.

Cats are often considered to be more aloof than dogs, but cats really can understand their owners" voices, a study has claimed. Japanese researchers have found that cats can distinguish their owners" voices from those of other people—implying that they do pay attention when spoken to. The study, from the University of Tokyo, examined felines in their home environment. It involved recordings of strangers, as well as of the cats" owners, but that cats could not see who was speaking to them. The researchers found that cats responded to voices by moving their heads and/or ears nearer the person who was speaking to them. Or, when the eats detected a familiar voice, they also had dilated pupils, which can signal emotions such as excitement, Discovery News reported. These reactions were more likely to occur when the cats heard their owners, voices or when they became increasingly familiar with strangers" voices.Study coauthor Atsuko Saito explained that dogs have evolved, and are bred "to follow their owners" orders" but eats have not been. So sometimes cats appear aloof, but they have special relationships with their owners. She added that eats have evolved not to show their emotions in order to survive. One example is illness, which they tend to hide because "in the wild, no one can rescue them and predators pay attention to such weak individual," she said.The researchers added that after 10,000 years of living with humans, domestic eats have the ability to communicate with us, and, generally speaking, we seem to understand them. The study, which will be published in the July issue of Animal Cognition, comes just weeks after an expert in animal behavior claimed we will one day be able to talk to animals using mobile phone-sized gadgets. Professor Con Slobodchikoff, of Northern Arizona University, is developing technology that interprets the calls of the prairie dog and says the technology could eventually be used to interpret other animals. He also believes the technology could one day be fine-tuned to enable humans to talk back to animals and engage in conversation. What would be the best title for the passage（）
