But there was a time when Les Angeles was nothing more than a tiny Indian village. The Spanish expedition searching for Monterey Bay camped there the night of August 1,1769. Twelve years later, other Spaniards started a settlement at the village, which remained unchanged for decades. Yankee sea traders used the settlement as a port, and the California gold rush brought some new economic life to the village, but the town remained quite small. It was not until the completion of the transcontinental railroads in 1869, and the discovery of oil in the 1890s, that the population began to grow. Later, during the two world wars, Los Angeles experienced move growth, in part because of the new airplane industry. At about the same time, the arrival of two New York motion picture producers in search of sunny weather marked the beginning of an entertainment industry that has become a multibillion-dollar industry today. In just the past 100 years, this tiny sea village has grown into the sprawling metropolis that we know today. (27) A．European expeditions in the 1700s. B．Famous sites in Los Angeles.

An American explorer John Charles Fremont travelled through the area in the early 1800's. He found the land shaped like a bowl. So he named it the Great Basin. It is a land of unusual beauty and sharp differences. For example, you can climb a mountain covered with green forests, then cool yourself in a field of snow as you arrive at the top. Here and there, sharp rocks push out through the snow. Among the rocks you might see homes of the golden hawk (鹰), a bird that was once in danger of dying out. You can camp in a campground on the edge of Lehman Caves. These caves are a group of large underground rooms made of limestone (石灰石). You can walk through them for about a kilometre. Before the park opened, the caves were the centre of interests for anyone travelling through this area. The state of Nevada has wanted a national park for more than 60 years. There have always been the opposite ideas from people who believes that a park would harm(损害) mining and agriculture. The bill that set up the park, however, promises that mines will remain open, and that sheep and cows will continue to feed on the mountainsides. Lehman Caves are______.

The area deforested in the past year was up 6% in 2003, far worse than the Brazilian government's predictions that it would rise by no more than about 2%. It was the second worst year for the destruction of the rainforest since satellite surveys began. It is reckoned that almost a fifth of the Brazilian part of the forest has now been wiped outs if it were to continue at this rate, it would all be flattened within the next two centuries. Things are hardly any better in those portions of Amazonia that lie in neighboring countries: Ecuador has lost about half of its forest, mainly due to illegal logging, in the past 30 years. Worse still, tropical forests have been disappearing at an even faster rate elsewhere in the world, such as in Africa. The world's greatest stores of biodiversity—and some of its main suppliers of the oxygen we breathe—are still being chewed up at an alarming rate, despite decades of talk among world leaders and environmentalists about the need to preserve them. As has been seen before in Brazil, the surge in the rate of deforestation is a sign that the country's economy is booming—recently it bas been growing at an annual rate of around 5%. Most of the timber felled illegally in Amazonia is sold to domestic buyers, in particular to the construction industry in Brazil's richer southern states. But the forest is also threatened by the rapid expansion of farming and ranching. In the past year, almost half of the total deforestation was in the state of Mato Grosso on the forest's southern part, where huge areas have been flattened to grow soybeans. Last year Brazil earned about $10 billion from exporting soy products, exceeding its income from coffee' and sugar, the country's traditional export crops. Mato Grosso's governor, Blairo Maggi, is also its soybean king—his family's farms are' the world's largest single producer of the crop. The rate at which the forest is being flattened could easily rise further. To boost the region's economic development and make attack on poverty, the government plans to asphalt(铺设沥青) and widen the BR-163 highway that slices the forest roughly in half, running from north to south. Though the government has been working with environmental groups and others to try to limit the scheme's impact, past experience has shown that improved road access invariably means more intrusion of the forest by loggers, ranchers, farmers, mineral prospectors and others. For much of Brazil's recent history, in particular during the country's 1964-85 military dictatorship, successive governments were obsessed(困扰) with populating and "developing" Amazonia, convinced that otherwise a foreign power might seize it. Large sums were spent building highways to open up the forest and a lot of subsidies were offered to get people to resettle there. However, the huge area of abandoned former forest land alongside previous road schemes show that, in fact, much of the region lacks suitable soil and climate for agriculture. More recent governments have taken the axe to the worse schemes that encouraged people to destroy the rainforest. Besides Brazil's tough conservation laws, there are now countl A．Y B．N C．NG
