In addition to improvements in the network of pipes, the government has been upgrading three recycled water plants in the south of the capital, said Zhao Lei, spokesman for the Beijing Municipal Commission of Development and Reform. "The transformation of the three plants has increased the recycled water processing capacity by 160,000 cubic meters per day," he said. In addition, the city is also speeding up the construction of sewage treatment plants to further recycle the sewage, Zhao said. Zhang Xiang, a researcher from Nature University, an environmental protection NGO in Beijing, said recycled water use should be promoted, especially in water-scarce cities such as Beijing. Setting up more recycled water plants in the capital will not only promote efficient water use, but also reduce costs because recycling water is much cheaper than transferring it over long distances, he said. According to the Beijing Water Authority, the capital will set up 46 more recycled water plants citywide in the next three years while upgrading 20 sewage treatment plants. The treatment rate of domestic sewage in downtown Beijing will reach 98 percent by the end of 2015, it said. The capital's recycled water is mainly used for industry, landscaping and cleaning, Zhang said. Many new communities in southern Beijing are equipped with a network to recycle water. In the past, people were not enthusiastic about using recycled water. However, as the government has boosted the quality of recycled water and set up more recycled water plants, more residents are gradually accepting it. Residents in southern Beijing will also enjoy more clean energy, as the government will replace traditional coal-burning stoves with electric radiators as part of a three-year plan to develop southern Beijing from 2013 to 2015. Since 2010, Beijing has taken measures to develop its southern areas. Earlier efforts have seen the region, which used to rely... Question: How many recycled water plants will the capital city have in about 3 years? Options: A: 46. B: 20 C: 3 D: 49

He had an unusual voice and he wanted to work in Disney's cartoon film for children. When Walt Disney heard Nash's voice, he said "Stop! That's our duck!" The duck was the now-famous Donald Duck, who first appeared in 1934 in the film The Wise Little Hen. Donald lived in an old houseboat and wore his sailor jacket and hat. Later that year he became a star after an eight-minute Mickey Mouse film. The cinema audience liked him because he was lazy and greedy, and because he lost his temper very quickly. And they loved his voice when he became angry with Mickey's eight nephews. Soon Donald was more popular than Mickey Mouse himself, probably because he wasn't a _ like Mickey. In the 1930s, 40s and 50s Donald and his friends Mickey, Goofy and Pluto made hundreds of Disney cartoons. He also made educational films about the place of the USA in the world, and safety in the home. Then in 1966 Donald Duck and his voice disappeared---there were no more new cartoons. Clarence Nash died in February, 1985. But today's children can still see the old cartoons on television and hear that famous voice. Question: When did Donald Duck become popular? Options: A: In 1933 B: In 1934 C: In 1966 D: In 1930

People use energy to run machines, heat and cool their homes, cook, give light, and transport people and products from place to place. Most energy comes from fossil fuels--petroleum, coal, and natural gas. However, burning fuels causes pollution. Also, if we don't find new kinds of energy, we will use up all the fossil fuels in the twenty-first century. Scientists are working hard to find other kinds of energy for the future. What might these sources of energy be? Energy from the wind All over the world, people use the power of the wind. It turns windmills and moves sailboats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy. Energy from water When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. In Brittany, France, for example, waterpower produces enough energy to light a town of 40,000people. Waterpower gives energy without pollution. However, people have to build dams to use this energy. Dams cost a lot of money, so water energy is expensive. Energy from the earth There is heat in rocks under the earth. Scientists use this heat to make geothermal energy. San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is possible only in a few places in the world. Energy from the sun Solar panels on the roofs of houses can turn energy from the sun into electricity. These panels can create enough energy to heat an entire house. Solar power is clean and there is a lot of it in sunny places. But when the weather is bad, there is no sunlight for energy. Question: What is the writer's opinion about the energy? Options: A: Try to use water energy more though it costs a lot. B: Each natural energy has its own advantages and disadvantages. C: Solar power is environmental. D: Wind power is the cheapest but we can't get.

The Palace of Placentia, an English Royal Palace built in 1447, no longer exists apart from a few remains under the present buildings. The grand buildings on the South Bank of the Thames at Greenwich were designed by Sir Christopher Wren, most famous for St. Paul's Cathedral. The buildings were finally completed in 1745, although some parts started to be used as early as 1705. They're now part of a university -- having served as a naval hospital and a naval college and the setting for several cinemas. But the buildings stand on a site which has a much longer history, of which now only a part remains that is below the ground. For nearly two hundred years, from around 1450 to 1650, Greenwich was one of the main royal palaces of England. Some of the most famous English rulers, such as Henry VIII and Elizabeth I, not only lived there, but also were born there. Henry VIII put an armory there, and there were also gardens, a great fountain and a mass of buildings. The Palace was also in a strategic location, because at the time either side of Greenwich on the Thames were important Royal Dockyards . Eventually, though, the Palace fell into disrepair. In 1664, the King at the time, Charles II, decided to replace it with completely new buildings in a modern style. Only a cellar from the former Royal Palace now remains, under one of the new buildings. Its red brick, typical of the 16th century, contrasts sharply with the white stone above it. Would you like to join us to have a good view of Greenwich? Question: According to the passage, when did the Palace of Placentia disappear from the ground? Options: A: In the late 1400s. B: In the early 1600s. C: In the late 1600s. D: In the early 1700s.
