The young couple had another quarrel. They were sitting silently when the landlady came in and asked, “You don’t   31   the house any more?” He kept silent and she   32   shook her head.

The landlady began   33   the house. After looking around, the landlady screamed, “See how you have   34   my house? The walls are full of nails! How could I rent it to others?”

She began looking around her   35  room. Four years ago on the wedding night, he felt deeply   36   to her, saying, “I feel so sorry to you for   37   you live in this small room. In the future I will buy our own big house.”

This tiny room has two nails on the wall next to the door, one for her bag and the other   38  . At that time, she threw all her stuff such as her bag and umbrella on the   39   once she entered the room, staring at the whole   40   and feeling terribly upset. Then he began   41   more nails into the wall. There were three nails on the left, on which   42   his clothes yesterday and four on the right used to   43   their wedding photo frame.

 The landlady started to pull the nails out with a tool. After the nails were   44  , the walls were left with countless holes. Suddenly, she felt heartbroken as if she were   45   nonstop through these holes.

　　She   46   to her feet and exclaimed, “Stop removing the nails! We will rent the house   47   we buy our own!” He gazed at her surprised, and then turned round, tears over his cheek.

She   48  realized that marriage was like a wall and that all   49   and “cold wars” were like the nails on the wall.  50  , when they were removed, only a wall with holes would remain. But if all the nails were still in their own places, the wall was still complete and reliable.

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.

It's a small gas station that has snacks, drinks, cigarettes, and candies. The young man behind the counter knows his   __36__   by name and what they normally want to buy. He treats children and adults with equal   __37__. He reads science fiction behind the counter when business is   __38__.

One day, three people rushed in and grabbed（抓住） food off the shelves as fast as they could,   __39__   not intending to pay for it. He hit the “panic button” , then went over the counter（柜台） and   __40__   the front door. It was obvious that they were homeless, and  equally obvious that they weren't going   __41__   with their ill­gotten（非法获得的） gains. They    __42__   the food and simply crowded together in panic（惊慌地）—knowing the police were   __43__   the way.

Imagine what they must have felt like when they were told they didn't have to steal if they were that    __44__. “We have food in the back, expired (到期)but still   __45__   to eat. If you need food, you   __46__   have some.” 

They were told to   __47__   what they had dropped and put it back, and then asked to straighten out（清理） the mess. They were doing just that    __48__    the police arrived. The officers were told the situation was under control and the police were no longer   __49__.

This wasn't what they had    __50__. They were being treated as human beings who could right the wrong they'd done. Shocked, they quickly followed orders to take turns and use the restroom to clean up.

Soon three   __51__   people walked out with all the    __52__   their arms could hold. They were   __53__   that，if they needed to come back again, they were to ask and not just grab.

And then the young man went back to read until the next customer came in. He would be the    __54__ person in the world to claim he was a hero. But he gave three people something they were in desperate need of—a   __55__amount of self­respect and a little bit of hope.
