False teeth have been found in Italy in human heads that are over 2,500 years old. They were made of bone and set in gold. However，for hundreds of years afterwards，the apparent dental skill of those early people was lost. Without false teeth people looked old before their time，since so many lost their teeth at an early age.
Toward the end of the 17th century，rich people could buy false teeth made from ivory. The teeth were tied together with silk thread，but it was difficult to keep them in the mouth. That was why rich people would rather buy teeth from the poor who would often sell their teeth to buy food and clothing.
Early in the 18th century a French doctor used steel springs to hold teeth in place. However，it was difficult to close one‘s mouth! Late in the same century porcelain (瓷)teeth set in gold were often used to make false teeth.
Although the use of artificial teeth increased，human teeth continued to be used also. In the 19th century，teeth from soldiers killed in battle were made into artificial teeth. For example，teeth from the dead in the American Civil War were sent to England.
By the middle of the 19th century，an American doctor，Claudius Ash，invented a better kind of porcelain tooth made of a special kind of hard rubber.

As an individual and societal resource, information has some interesting characteristics that separate it from the traditional notions of economic resources. Unlike other resources, information is expansive, with limits apparently imposed only by time and human cognitive capabilities. Its expansiveness is attributable to the following: (1) it is naturally diffusive; (2) it reproduces rather than being consumed through use; and (3) it can' be shared only, not exchanged in transactions. At the same time, information is compressible, both syntactically and semantically.
The second perception of information is that it is an economic commodity, which helps to stimulate the worldwide growth of a new segment of national economies-the information service sector. Taking advantage of the properties of information and building on the perception of its individual and societal utility and value, this sector provides a broad range of information products and services. By 1992 the market share of the U.S. information service sector had grown to about $ 25 billion. This was equivalent to about one-seventh of the country's computer market, which, in turn, represented roughly 40 percent of the global market in computers in that year. However, the probable convergence of computers and television (which constitutes a market share 100 times larger than computers) and its impact on information services, entertainment, and education are likely to restructure the respective market shares of the information industry before the onset of the 21st century.
The first paragraph is mainly about ______.
A．the remarkable rise in information-processing activities
B．a sharp increase in information-intensive activities
C．information as an economic resource
D．the birth of information society
How did language arise in the first place？ There are many theories about this, based on various types of indirect evidence, such as the language of children, the language of primitive societies, the kinds of changes
that have taken place in language in the course of recorded history, the behavior. of higher animals like chimpanzees, and the behavior. of people suffering from speech defects. These types of evidence may provide us with pointers, but they all suffer from limitations.
When we consider the language of children, we haw to remember that their situations are quite different from those of our earliest human ancestors because the child, growing up in an environment where there is al- ready a fully developed language, is surrounded by adults who use that language and are teaching it to him. For example, it has been shown that the earliest words used by children are mainly the names of things and people ("doll," "spoon," "Mummy"), but this fact does not prove that the earliest words of primitive man were also the names of things and people. When the child learns the name of an object, he may then use it to express his wishes or demands.
"Doll!" often means,. "Give me my doll!" or "I've dropped my doll. Pick it up for me!" The child is us- ing language to get things done, and it is almost an accident of adult teaching that the words used to formulate the child's demands are mainly nouns instead of words like "Bring!" "Pick Up!" and so on.
Theories of the origin of language include all of the following EXCEPT______.
A．communication among primitive men
B．the need to communicate
C．the language of children
D．the first man's extensive vocabulary
