"How far is it to the next village" the American asks a man sitting by the side of the road. In some countries, because the man realizes that the traveler is tired and eager to get to his destination (目的地) ,he will politely say "Just down the road." He thinks this is more encouraging, gentler, and therefore the wanted answer. So the American drives through the night, getting more and more angry, feeling "tricked". He thinks the man purposely cheated him, for obviously he must have known the distance quite well.
Had conditions been turned over, the American would have felt he was "cheating" the driver if he had said the next town was close when he knew it was really 15 miles further on. Though, he, too, would be sympathetic (同情的) to the weary driver, he would say "You have a good way to go yet; it is at least 15 miles. "The driver might be disappointed, but he would know what to expect.
Whether to be correct or poli
A. he is playing a trick on him
B. the American expects the answer
C. he doesn’t know the exact distance at all
D. he wants to encourage him to go further

The market is a concept. If you are growing vegetables in your backyard for sale you are producing for the market. You might sell some to your neighbor and some to the manager of the local supermarket. But in either case, you are producing for the market.
Your efforts are being directed by the market. If people stop buying vegetables, you will stop producing them.
If you take care of a baby to earn money, you are producing for the market. If your father is a steelworker or a truck driver or a doctor or a grocer, he is producing goods or service for the market.
When you spend your income, you are buying things from the market. You may spend money in supermarkets, department stores, and restaurants. Still you are buying from the market. When the local grocer hires you to drive the delivery truck, he is buying your labor in the labor market.

A. Selling and Buying.
B. What Is the Market
