use to communicate with each other. Karl von Frisch, a professor from Austria, devoted many years of his life
to researching the ways honey-bees communicate in their hives (蜂房). Karl von Frisch built special hives, a
glass wall and painted some honey-bees with different colors.
A marked bee which returned to the hive from the feeding table performed a dance on the surface of the
honeycomb (蜂巢). First it made a circle to the right, then to the left. It repeated these circles again and again.
The surrounding bees copied its dances and then they left for the feeding place.
Karl von Frisch set up two feeding places. One was close to the hive the other was farther away. The bees
that had been at the nearby feeding place were doing the circling dance. The bees at the distant feeding place
were dancing differently. The dancer ran in a straight line, wagging (摇摆) from side to side. Then it turned in
a semicircle (半圆), ran straight again, and turned in another semicircle to the opposite side. It repeated the
dance over and over. The dances convey messages about the far-away feeding place. Karl von Frisch and his
assistants slowly moved a feeding place close to the hive farther and farther away and they counted how many
times the bees repeated the dance in one minute. Finally they found out the number of wagging dances per
minute told the exact distance to the feeding place.

| Advertising is a form of communication that uses all kinds of media, and is visible everywhere these days. Typical customers of advertising companies are other companies, or businessmen, who want to persuade potential customers to buy more of what they make or sell. But there are other kinds of customers. Some organizations spend large sums of money on advertising a political party or other group that sells what is not, strictly speaking, a product or service. Such non - profit organizations are not typical advertising customers, and they prefer ways of spreading knowledge, changing attitudes, and improving society. Many advertisements are designed to increase sales of products and services by either improving brand image or, in the case of non - profit organizations, expressing ideas. In order to achieve th~s, advertisements will often pass on truthful information while delivering their messages. Every major medium is a means of delivering these messages, including television, radio, cinema, magazines, newspapers, video games, the Internet and billboards (大幅广告牌). Advertising will usually be created and. placed by an advertising agency on behalf of company or other organization. Spending on advertising has increased greatly in recent years. In 2006, spending was estimated at $155 billion in the United States and $385 billion worldwide; the latter is expected to reach more than $500 billion by 2010. While advertising can be seen as a necessity for economic growth and social development, it is not without social costs. Advertisement emails and other forms of junk mail have become so popular that ~they have become a major burden to users of I nternet email services, as well as a financial burden on Internet email service providers.
