Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources（来源）, as well as one of the oldest. Evidence shows that windmills（风车）began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

For many centuries, people used windmills to grind（磨碎）wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s, when electricity was available to people in almost all areas of the United States, windmills were rarely used.

During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

Although Paris is often considered the city of romance， close to a million adults who call it home are single. Many single people say that France’s capital is one of the most difficult places to meet people. The complaints（抱怨）of this lonely group have inspired a new phenomenon known as “supermarket dating.”At Galerie Lafayette Gourmet，singles can shop for more than just the items on their grocery list. They can look for someone who has blue eyes， brown hair，and is 1.8 meters tall，or whatever may be on their romantic shopping list.

At this paris location，single people of all ages can schedule their shopping for Thursday nights between 6:30 and 9:00 p.m. When they walk through the door，they pick up a purple basket to advise that they are looking for love. They try to arrive early because the baskets disappear quickly，and then they have to wait in line for their turn to wander the store aisles（过道）.

With purple baskets in hand， shoppers can consider their romantic options while they pick out their groceries. When they are ready to pay， they can go to the checkout line for singles who want to chat.

Most of the people who look for love in the supermarket are skeptical of Internet dating. They know that it is easy to embellish（美化）one’s appearance or to lie about one’s age over the Internet. The supermarket， on the other hand，is considered a safe and casual environment in which to meet a potential match. In addition， what one finds in another’s grocery basket can say a thing or two about that person’s character or intentions. Buying pet food can be a man’s way of showing a potential match that he has a sensitive side. Women who fill their baskets with low-fat food show their healthy style of living. These days it’s possible to find much more than food at a grocery store.

     Silence is unnatural to man. He begins life with a cry and ends it in stillness. In between be does all he can to make a noise in the world, and be fears silence more than anything else. Even his conversation is an attempt to prevent a fearful silence. If he is introduced to another person, and is number of pauses occur in the conversation, he regards him- self as a failure ,a worthless person, and is full of envy of the emptiest- headed chatterbox（喋喋不休的人）.He knows that ninety nine percent of human conversation means no more than the buzzing of a fly, but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure（蜡塑人像）.

The aim of conversation is not. For the most part, to communicate ideas; it is to keep up the buzzing sound. There are, it must be admitted, different qualities of buzz; there is even a buzz that is as annoying as the continuous noise made by a mosquito(蚊子).But at a dinner party one would rather be a mosquito than a quiet person. Most buzzing, fortunately, is pleasant to the ear, and some of it is pleasant even to the mind. He would be a foolish man if he waited until he had a wise thought to take part in the buzzing with his neighbors.

     Those who hate to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish to talk. Very few human beings join in a conversation in the hope of learning anything new. Some of them are content if they are merely allowed to go on making a noise into other people’s ears, though they have nothing to tell them except that they have seen two or three new plays or that they had food in a Swiss hotel. At the end of an evening, during which they have said nothing meaningful for a long time. They just prove themselves to be successful conservationists.
