Natural Gas1 Natural gas is produced from reservoirs deep beneath the earth's surface. It is a fossil fuel(矿物燃 料),meaning that it is derived from organic material buried in the earth millions of years ago.The main corn- ponent of natural gas is methane(甲烷).2 The popularity and use of clean natural gas have increased dramatically over the past 50 years as pipeline infrastructure(基础设施)has been installed to deliver it conveniently and economically to millions of residential,commercial and industrial customers worldwide.Today,natural gas service is available in all 50 states in the U.S.,and is the leading energy choice for fueling American homes and industries.More than 65 million American homes use natural gas.In fact,natural gas is the most economical source for home energyneeds,costing one-third as much as electricity. In addition to heating homes,much of the gas used in the United States is used as a raw material to manufacture a wide variety of products,from paint,to fibers for clothing,to plastics for healthcare,computing and furnishings.Natural gas is also used in a significant number of newelectricity-generating power plants.3 Natural gas is one of the safest and cleanest fuels available. It emits(发出)less pollution than other fossil fuels sources. When natural gas is burned,it produces mostly carbon dioxide(二氧化碳)and water va- por一the same substances emitted when humans breathe.Compared with some other fossil fuels,natural gas emits the least amount of carbon dioxide into the air when combusted(燃烧)一making natural gas the clea-- nest burning fossil fuel of all.4 The United States consumes about one-third of the world's natural gas output,making it the largest gas-consuming region in the world.The U.S.Department of Energy Information Administration forecasts thatnatural gas demand will grow by more than 50 percent by 2025.5 There are huge reserves of natural gas beneath the earth's surface.The largest reserves of natural gas can be found in Russia , West and North Africa and the Middle East. LNG(液化天然气)has been pro- duced domestically and imported in the United States for more than four decades.Today,the leading import-ers of LNG are Japan,Korea,France and Spain.Natural gas is recognized as the most economical energy source______________.A:over the past 50 yearsB:beneath the earth's surfaceC:by more than 50 percentD:for more than four decadesE:as a raw materialF:for home energy needs
