TEXT C The Virus Hunters The mouth of the Amazon River has long been a starting place for hunters going to the jungles of Brazil. In recent years it has been, too, the headquarters for a middle-aged American couple who hunt the smallest living things and perhaps the most deadly viruses. Dr Causey and his wife have discovered more new types and more old ones in new places than all of the other search teams. Dr. Causey insists that the couple’s success is due more to the number of viruses in the forests of the Amazon than to the skill he and his wife have developed during their eighteen years of work in Brazil. "We have found the loveliest diseases fight in our backyard," he told me one day as we walked through a light rain along a jungle trail. "Oh, these viruses are here all fight. There is in the jungle a great pool of disease which is carried in the blood of animals and birds. Some of the diseases can be caught by people. It may be that we shall find that the jungle is a great center of virus disease and that it overflows from here to other parts of the world. It may be that birds carry the viruses to far countries. It may be that some viruses which presently reproduce in man without making him ill, may change and become deadly to him. ’Viruses waiting for a disease,’ they are sometimes called. This is just an idea, you understand. We do not know, but it is important that we find out, and the first step in finding out is to learn what viruses there are in the jungles." There is a Brazilian story about the beginning of the world which goes: "When God was making the world he tried to keep everything in balance. When he made a desert, he provided it with some green places. When he made a land that was beautiful, he gave it storms and other terrible things caused by the weather, where the earth was rich below the surface, it was also made hard to live on, where the land could be farmed, the weather was made too hot or too cold or too dry. Where there was enough water, God made it so that there should sometimes be too much water. "But in one place God made a land that was rich, where everything grew easily, where it was not too hot and certainly not too cold, where animals were plentiful and fruit hung from the trees all the year round." "The angels looked at this loveliness and were jealous of man. They asked God if this was not too beautiful, too much like heaven, this valley of the Amazon." And God said, "True, this land looks like heaven, but wait until you see what happens to man when he tries to live in it." "Viruses waiting for a disease" refers to ______.

Russian-born Max Weber grew up in New York, studied art there, and then went back to Europe to familiarize himself with contemporary artistic developments, on returning to the United States, Weber worked in the new styles he had discovered in Paris and soon became recognized as a pioneer of American abstract painting. An example of his work at the National Gallery of Art in Washington D. C. is a 1915 painting entitled "Rush Hour, New York. " Using abstract, geometrical forms, Weber has expressed the movement, noise, and vibrancy of the great metropolis. The picture blends elements of two European styles: cub- ism, which shows subjects from a number of different angles of vision at the same time, and futurism, which portrays speed and objects in motion. Forceful lines and spiky forms throughout the composition convey the energy and vitality of the city, Weber expresses the city’s diversity by juxtaposing forms with rounded and angular shapes to suggest specific elements of the urban landscape: skyscrapers, flashing lights, and hurrying people. The mood of the painting "Rush Hour, New York" can be best described as（）

TEXT A1 MOSCOW, Russia (Reuters)-The personal fortunes of Russia’s 100 richest businessmen are as big as a quarter of the nation’s entire economy, business journal Forbes says.2 "Capital in Russia is not only concentrated in the hands of a small group of people, but also associated with just one city," Forbes said in a press release ahead of publishing a list of Russia’s 100 wealthiest.3 "No other city in the world can boast such a large number of billionaires as Moscow."4 Russia’s biggest billionaire Mikhail Khodorkovsky, the main shareholder in oil company YUKOS, will find it hard to enjoy his fiches, although he too is in the Russian capital.5 Khodorkovsky is worth $15.2 billion, but is languishing in a Moscow jail awaiting trial for fraud and tax evasion.6 The charges against Khodorkovsky are widely seen as part of a Kremlin campaign to destroy the politically ambitious magnate’s influence.7 His arrest has found wide support in Russia, the world’s second largest oil exporter, where the vast majority of people have gained little from the privatisations of the early 1990s.8 "By contrast, the combined net worth of all American billionaires is equivalent to just six percent of the gross domestic product of USA," said Forbes.9 In this year’s Forbes full list of the world’s billionaires published in February, Khodorkovsky was followed among Russians by Roman Abramovich, the owner of English premier league football club Chelsea. Abramovich’s wealth was valued at $10.6 billion.10 On the Forbes list published on February, the other names making up the Russian top 10 were Mikhail Fridman on $5.6 billion, Vladimir Potanin on $4.9 billion, Mikhail Prokhorov on $4.8 billion, Vladimir Lisin on $3/8 billion, Alexei Mordashov on $3.5 billion, Oleg Deripaska and Viktor Vekselberg, both on $3.3 billion, and Vagit Alekperov on $2.7 billion. What can be concluded from the third paragraph
If we view a science as a body of systematized knowledge, then chemistry is usually called a natural science because it (26) knowledge of the natural world. At times we may wonder (27) there is no complete system (28) all of chemistry fits perfectly. Gaps in the present system, however, show that chemistry is still a(n) (29) subject and that we (30) all of its facts, laws, and theories. (31) , chemistry as a science is very much (32) us today, and its future holds the bright promise (33) much more to come. Man’s knowledge about himself and nature has grown into (34) sciences. The growth of the separate sciences has been more developmental than intentional. The separation of the natural sciences into physical and biological sciences, and physical sciences into physics and chemistry, happily (35) a larger body of knowledge into more manageable parts. At the same time we should remember that the concepts, techniques, and applications of the various sciences are interdependent and not exclusively a part of one science or (36) . In this (37) , chemistry is a key science among the natural sciences because everyone, (38) the area of natural science he wishes to pursue, needs at least an introduction to the principles and simpler applications of chemistry as a foundation for his specialty. Chemistry deals with the (39) of matter, changes in matter, the laws and principles (40) these changes, and the concepts and theories that interpret them.
