Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, way back in the eleventh century B.C. We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and authority. In the Far East in ancient times, the umbrella was allowed to be used only by royalty or by those in high office. In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans. During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered a symbol of power and authority. By 1680, The umbrella appeared in France, and later on in England. By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style. during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that women's umbrellas began to be made, in a whole variety of colors. The first use of umbrella was as ______. A．protection against rain B．a shade against the sun C．a symbol of power D．a symbol of honor

A．much of B．as of C．as much of D．such

The valley's business ecology depends on failure the same way the tree-covered hills around us depend on fire it wipes out the old growth and creates space for new life. The valley has always been in danger of drowning in the unwelcome waste products of success too many people, too expensive houses, too much traffic, too little office space and too much money chasing too few startups. Failure is the safety valve, the destructive renewing force that frees up people, ideas and capital and recombines them, creating new revolutions. Consider how the Internet revolution came to be. After half a decade of start-up struggles, for example, hundreds of millions of Hollywood dollars were going up in smoke. It all seemed like a terrible waste, but no one noticed that the collapse left one very important byproduct, a community of laid-off C++ programmers who were now expert in multimedia design, and out on the street looking for the next big thing. These media geeks were the pioneer of the dot-com revolution. They were the Web's business pioneers, applying their newfound media sensibilities to create one little company after another. Most of these start-ups failed, but even in failure they advanced the new medium of cyberspace. A few geeks, like Silicon Graphics founder Jim Clark, succeeded and utterly changed our lives. In 1994 Clark was unemployed after leaving the company be founded, doggedly trying to develop a new interactive-TV concept. He approached Marc Andreessen, the co developer of Mosaic, the first widely used Internet browser, in hope of persuading Andreessen to help him design his new system. Instead, Andreessen opened Clark's eyes to the Web's potential. Clark promptly tossed his TV plans in the trash, and the two co-founded Netscape, the cornerstone of the consumer-Web revolution. Like the interactive-TV refugees and generations of innovators before them, the dot-comers are already hatching new companies. Many are revisiting good ideas executed badly in the 1990s, while others are striking out into entirely new spaces. This happy chaos is certain to mature into a new order likely to upset an establishment, as it delivers life-changing wonders to the rest of us. But this is just the start, for revolutions give birth to revolutions. So let's hope for more of Silicon Valley's successful failures. What is implied in the first sentence？ A．The Silicon Valley blamed its failure on the success of Wall Street. B．The Silicon Valley is also noted for its complex ecological web. C．The Silicon Valley takes a vain pride in its overabundant successes. D．The Silicon Valley would benefit from the collapse in certain ways.

No clear-cut distinction can be drawn between professionals and amateurs in science: exceptions can be found to any rule. Nevertheless, the word "amateur" does carry a connotation that the person concerned is not fully integrated into the scientific community and, in particular, may not fully share its values. The growth of specialisation in the nineteenth century, with its consequent requirement of a longer, more complex training, implied greater problems for amateur participation in science. The trend was naturally most obvious in those areas of science based especially on a mathematical or laboratory training, and can be illustrated in terms of the development of geology in the United Kingdom. A comparison of British geological publications over the last century and a half reveals not simply an increasing emphasis on the primacy of research, but also a changing definition of what constitutes an acceptable research paper. Thus, in the nineteenth century, local geological studies represented worthwhile research in their own right; but, in the twentieth century, local studies have increasingly become acceptable to professionals only if they incorporate and reflect on the wider geo logical picture. Amateurs, on the other hand, have continued to pursue local studies in the old way. The overall result has been to make entrance to professional geological journals harder for amateurs, a result that has been reinforced by the wide spread introduction of refereeing, first by national journals in the nineteenth century and then by several local geological journals in the twentieth century. As a logical consequence of this development, separate journals have now appeared aimed mainly towards either professional or amateur readership. A rather similar process of differentiation has led to professional geologists coming together nationally within one or two specific societies, whereas the amateurs have tended either to remain in local societies or to come together nationally in a different way. Although the process of professionalisation and specialisation was already well under way in British geology during the nineteenth century, its full consequences were thus delayed until the twentieth century. In science generally, however, the nineteenth century must be reckoned as the crucial period for this change in the structure of science. The growth speeialisation in the 19th century might be more clearly seen in sciences such as ______. A．sociology and chemistry B．physics and psychology C．sociology and psychology D．physics and chemistry

A．respectful B．respective C．respecting D．respectable

Since 1945, the entire literary picture has changed. Fiction of ail kinds, but above all the short story, has become more and more uneconomic to publish. Many magazines have gone out of business. As a type, the "man of letters", puffing a pipe, has almost vanished, to be replaced by the university lecturer or the television scriptwriter. The public is not attracted by imaginary plots in books but prefers the actual, the real story of real people. For those who do not read at all, television provides an enticing alternative. Such a decline is in many ways a sad one because the old-time short story had a human quality about it which is now eroded. Yet, in an odd way, in our chaotic electronic age, the short story still has a prospect of living. It has been discovered by film scriptwriters that the form. of the short story provides a useful structure for television; it readily provides the basis for a one-hour programme. The best title for this passage is ______. A．The Short Story and Television B．The Short Story and the Public C．The Short Story: Past and Present D．The Short Story: Form. and Content

A．lonesome B．alone C．lone D．lonely
