共用题干 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 orgaiiic 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 new electricity-generating power plants.3 Natural gas is one of the safest and cleanest fuels available. It emits（发出）less pollution than other fossil fuel 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一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 that natural 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.Paragraph 3__________A:Popularity and Use of Natural GasB:Natural Gas Reserves and SupplyC:Natural Gas PricesD:Clean Fuel of ChoiceE:Disadvantages of Natural GasF:Natural Gas Consumption

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.When manufacturing many different products,people commonly use natural gas_________.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
Renewable electricity generation is now on par with ______ of natural gas, which remained relatively stable in last years.A.the one B.which C.that D.what
共用题干 第二篇Home HeatingCentral heating became popular only after the Civil War.Typically,coal-burning furnaces（火炉）fueled the early systems.Natural gas had developed into the leading fuel by 1960.Its acceptance resulted in part from its wide uses.Because it comes primarily from U.S.and Canadian fields , natural gas is also less vulnerable（脆弱的）than oil is to war.Oil remains the most important fuel in a few areas,such as New England.Electric heating dominates most areas with mild winters and cheap electricity,including the South and the Northwest.It was made popular at least in the South by the low cost of adding electric heating to new houses built with air-conditioning.Bottled gas,which is somewhat more expensive than utility gas,is the fuel of choice in rural areas not served by utility pipelines.Wood is the leading heating fuel in just a few rural counties.Home heating,which accounts for less than 7 per cent of all energy consumed in the U.S.,has had a commendable（值得赞扬的）efficiency record : from 1 978 to 1 997 , the amount of fuel consumed for this purpose declined 44 per cent despite a 33 per cent increase in the number of housing units and an increase in house size.TheU.S.Department of Energy,however,forecasts that energy used in home heating will rise by 14 per cent over the next two decades.That rise is small considering an expected 21 per cent increase in the number of houses and the trend toward larger houses.Natural gas and electricity will probably dominate the home heating market for the next two decades.Solar（太阳的）heating never became popular because of cost and limited winter sunlight in most areas;in 2000 only 47,000 homes relied on it.Which of the following statements is NOT true,according to the article?A:Natural gas comes partly from Canadian fields.B:Bottled gas is more expensive than utility gas.C:Equipment for home heating has been considerably improved.D:Solar heating dominated America in 2000.
