单选题The Old Gate In the Middle Ages the vast majority of European cities had walls around them. This was partly for defensive (51) but another factor was the need to keep out anyone regarded as undesirable, like people with contagious (52) . The Old City of London gates were all (53) by the end o the 18th century. The last of London's gates was removed a century ago, but by a (54) of luck, it was never destroyed. This gate is, in (55) fact, not called a gate at all; its name is Temple Bar, and it marked the (56) between the Old City of London and Westminster. In 1878 the Council of London took the Bar down, numbered the stones and put the gate in (57) because its design was (58) it was expensive to (59) and it was blocking the traffic.

单选题Eiffel Is an Eyefull Some 2,300 meters up, near the Eiffel Tower's wind-whipped summit the world comes to scribble. Japanese, Brazilians, Americans--they graffiti their names, loves and politics on the cold iron--transforming the most French of monuments into symbol of a world on the move. With Paris laid out in miniature below, it seems strange that visitors would rather waste time marking their presence than admire the view. But the graffiti also raises a question: Why, nearly 114 years after it was completed, and decades after it ceased to be the world's tallest structure, is la Tour Eiffel still so popular? The reasons are as complex as the iron work that graces a structure some 90 stories high. But part of the answer is, no doubt, its agelessness. Regularly maintained, it should never rust away. Graffiti is regularly painted over, but the tower lives on. "Eiffel represents Paris and Paris is France. It is very symbolic, " says Hugues Richard, a 31-year-old Frenchman who holds the record for cycling up to the tower's second floor--747 steps in 19 minutes and 4 seconds, without touching the floor with his feet. "It's iron lady, it inspires us," he says. But to what? After all, the tower doesn't have a purpose. It ceased to be the world's tallest in 1930 when the Chrysler Building went up in New York. Yes, television and radio signals are beamed from the top, and Gustave Eiffel, a frenetic builder who died on December 27, aged 91, used its height for conducting research into weather, aerodynamics and radio communication. But in essence the tower inspires simply by being there--a blank canvas for visitors to make of it what they will. To the technically minded, it's an engineering triumph. For lovers, it's romantic. "The tower will outlast all of us, and by a long way," says Isabelle Esnous, whose company manages Eiffel Tower.

单选题Smoking Since 1939, numerous studies have been conducted to determine whether smoking is a health hazard. The trend of the evidence has been consistent and indicates that there is a serious health risk. Research teams have conducted studies that show beyond all reasonable doubt that tobacco smoking is associated with a shortened life expectancy. Cigarette smoking is believed by most research workers in this field to be an important factor in the development of cancer of the lungs and cancer of the throat and is believed to be related to cancer of some other organs of the body. Male cigarette smokers have a higher death rate from heart disease than non-smoking males. Female smokers are thought to be less affected because they do not breathe in the smoke so deeply. Apart from statistics, it might be helpful to look at what tobacco does to the human body. Smoke is a mixture of gases, vaporized chemicals, minute particles of ash and other solids. There is also nicotine, which is powerful poison, and black tar. As smoke is breathed in, all those components will be from deposits on the membranes of the lungs. One point of concentration is where the air tube and bronchus divides. Most lung cancer begins at this point. Filters and low tar tobacco are claimed to make smoking to some extent safer, but they can only slightly reduce, not eliminate the hazards.

单选题Vodafone Enters UK iPhone Market Vodafone has reached an agreement to sell Apple's popular iPhone in the UK. The announcement follows news that network operator Orange had secured a similar agreement with Apple. The deals mark an end to the exclusive UK arrangement between O2 and the US technology firm, which has been in place since 2007. Vodafone says users can register an interest online, with the handsets becoming available to customers from early 2010. Orange said its customers would be able to buy the phone" later this year" but did not specify a date or pricing. Vodafone is one of the biggest mobile operators in the world with an estimated 300 million customers world wide, making it the second largest carrier after China Mobile. The agreement sees both Orange and Vodafone selling both the iPhone 3G and iPhone 3GS. A spokesperson for Vodafone said the firm was" delighted" at securing an agreement with Apple and that the phone was going to be primarily for existing Vodafone customers. This is a different model from that adopted by O2, which used the iPhone as an incentive to attract new customers. O2 has offered the handset in the UK since its launch in 2007. In February, it said it had sold more than one million of the handsets. The launch of the latest iPhone 3GS in June significantly boosted sales, with many stores running out of stock. The phone has also allowed the firm to win subscribers from other networks, according to analysts. Dave McQueen, principal analyst at Informa Telecoms and Media told BBC News said that the smartphones-which have the ability to surf the web and send e-mail-has put a burden on the O2 network. "IPhone users to tend to use data quite extensively-perhaps more than anticipated," he said. O2 will continue to sell the handset in Britain, alongside iPhone rival the Palm Pre. The Palmphone, described by some as an "iPhone killer", will be available exclusively to O2 from 16 October. O2 said that it always knew that its exclusive deal was for "a limited period of time". In countries where exclusive deals still persist, such as the US, some customers choose to "unlock" their phones using third party software so they work on an unlicensed network. However, Apple has warned that the practice can cause "irreparable" damage to a handset and has engaged in a game of cat-and-mouse, releasing periodic software updates which prevent unlocked phones from working correctly.

单选题{{B}}第三篇{{/B}} {{B}} China's Mineral Deposits{{/B}} China's vast territory and complicated geological formations create favorable conditions for mineralization. Rich mineral deposits are found on the plains and in the mountains. Reserves of over 50 metals and nearly 80 non-metals have been discovered, in addition to rich fuel-bearing deposits. These include rich deposits of nonferrous metal, rare-earth metal, coal and certain non-metals. The proved reserves of a number of minerals are among the richest in the world, including rare earth, coal, iron, copper, tin, lead, zinc and aluminum. The prospects for petroleum and natural gas are also bright. The abundance of minerals provides a solid material basis for the country's modernization. Nevertheless, there are also some inadequacies. Most of the minerals are unevenly distributed and the prospects of some reserves are not clear. Insufficient reserves have been proved for some minerals: others, such as iron and copper, do not usually occur in rich veins. The reserves of quite a number of minerals are among the largest in the world, but the per capital amount is smaller than that in many other countries. Although China has conducted a great many preliminary surveys, the work has to be in tensified in the eastern part of the country, and it has hardly begun in many places in the west. Prospecting and exploitation are still rather backward. China has only just opened the door to its underground treasure house, where the mysteries have by no means been uncovered. With the progress in geological research and exploration, more and better minerals will be found.

单选题"Salty" Rice Plant Boosts Harvests British scientists are breeding a new generation of rice plants that will be able to grow in soil containing salt water. Their work may enable abandoned farms to become productive once more. Tim Flowers and Tony Yeo, from Sussex University"s School of Biological Sciences, have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pair have recently begun a three-year programme, funded by the Biotechnology and Biological Sciences Research Council, to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice. It is estimated that each year more than 10m hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts (妨碍生长) plants. The problem is caused by several factors. In the tropics, mangroves (红树林) that create swamps (沼泽) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (渗透) in Latin America, irrigation often causes problems when water is evaporated (蒸发) by the heat, leaving salt deposits behind. Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive. To overcome these problems, Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants" growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resulting seeds are ready to be considered for commercial use. Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food in the poorer countries of the world.

单选题{{B}}第三篇{{/B}} {{B}} Mysterious Nazca Drawings{{/B}} One of the most mysterious archaeological spectacles in the world is the immense complex of geometrical symbols, giant ground-drawings of birds and animals, and hundreds of long, ruler-straight lines, some right across mountains, which stretch over 1,200 square miles of the Peruvian tablelands, at Nazca. Nazca was first revealed to modern eyes in 1926 when three explorers looked down on the desert from a hillside at dusk and briefly saw a Nazca line highlighted by the rays of the sun. But it was not until the Peruvian airforce took aerial photographs in the 1940s that the full magnificence of the panorama was apparent. Hundreds of what looked like landing strips for aircraft were revealed. There were eighteen bird-like drawings, up to 400 feet long, four-sided figures with two lines parallel; and long needle-like triangles which ran for miles. Among the many abstract patterns were a giant spider, a monkey, a shark, all drawn on the ground on a huge scale. The scale is monumental, but from the ground almost invisible and totally incomprehensible. The amazing fact about Nazca, created more than 1,500 years ago, is that it can only be appreciated if seen from the air. Many, therefore, regarded it as a prehistoric landing ground for visitors from outer space, but Jim Woodman, an American explorer, who was long fascinated by the mystery of Nazea, had a different opinion. He believed that Nazca only made sense if the people who had designed and made these vast drawings on the ground could actually see them, and that led him to the theory that the ancient Peruvians had somehow learned to fly, as only from above could they really see the extent of their handiwork. With this theory in mind, he researched into ancient Peruvian legends about flight and came to the conclusion that the only feasible answer was a hot-air balloon. To prove his theory, Woodman would have to make such a thing using the same fabrics and fibers that would have been available to the men of Nazca at the time. He started by gathering information from ancient paintings, legends, books and archaeological sites. After many attempts, Woodman built a balloon-type airship. It took him into the air, letting him have the sensation he had never had from viewing the same ground that he had seen many times. His flight was a modern demonstration of an ancient possibility.
