One of Britain's few distinctive contributions to world culture may come to an end, according to a survey that suggests holiday postcards are more and more given up because of emails and instant messages in mobile phones.
More than half of the 1000 holiday-makers interviewed said they had decided to send fewer cards, turning instead to their electronic rivals. A quarter of the respondents (受调查者) regard postcards as old-fashioned and slow to arrive. A further 14% admitted that thinking of something to fill the space was too challenging, compared with a call home.
Although officially invented by a Hungarian, Emanuel Herrmann, in 1869, the idea of illustrated cards was taken up with most enthusiasm in Victorian Britain, joining Gothic architecture and landscape gardening as fields for which the country was famous.
"If the British postcard did disappear, we would lose forever something of great importance to the nation, "said Chris Mottershead of Thomson Holidays, which did the survey. He was backed by Marie Angelou of Sussex University, who has investigated the importance of sending and receiving postcards. "Postcards are nothing like phone calls, instant messages and direct photo shots via the mobile, "she said. "All these are useful, practical devices, but postcards offer something else, something additional that is not simply functional, but imaginative and personal. They can create the real atmosphere of your holiday in a way that nothing else can do. They are also for more than a moment—with some people adding them to collections built up over years and years.
Who first got the idea of illustrated cards？
A．Emanuel Herrmann.
B．Victorian Britain.
C．Chris Mottershead.
D．Marie Angelou.

A patent is an exclusive right given to an inventor for his or her invention. In other words, a patent is a monopoly right given to the inventor for the invention. A patent confers on the inventor the right to price and to sell the invention in any way he or she desires, in the United States, patents are granted by the Patent Office for 17 years. Although economists generally condemn monopoly as a form. of market organization since monopoly imposes costs on the economy, patents present a more subtle case for monopoly theory. Specifically, can patent monopolies be justified？
In general, economists complain about the costs of monopoly because they believe that the same industry could be organized competitively. A patent monopoly grant for 17 years presents a different problem. That is, the purpose of the patent system is to encourage invention. The issue is not monopoly versus competition but, more fundamentally, invention versus no invention. Is the world better off with the invention, even though it is monopolized for 17 years？ In other words, what are the costs and benefits of a patent？
Consider the simple case of a new consumer product with a positive demand, such as a camera utilizing a new exposure process. The costs of the patent monopoly are simply the deadweight costs of monopoly measured by the lost consumers' surplus from the 17-year patent monopoly. This cost must be assessed carefully in the context of an invention, however. What are the benefits of the patent system？ First, there is the increase in consumer well-being brought about immediately by a desirable invention. In 17 years, the patent monopoly ends, and a second source of benefits arises: The price of cameras will fall to a competitive level, and consumers will reap the benefits of the camera at a lower price. In sum, theory of monopoly helps us to assess the costs and benefits of the patent. One can quibble about patent monopolies, arguing, for example, that they are granted for too long a time.
In the end, the patent system creates goods and services and technologies that did not previously exist. In this respect it is a valuable System for the economy. The patent system also underscores the importance of property rights to ideas as a source of economic growth and progress.
The first paragraph mainly______.
A．focuses on business monopoly
B．tells us about the patent system in America
C．discusses a special form. of market organization
D．defines what a patent is and its function
