Natural Gas

1 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 energy
needs,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 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 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.

根据下列内容，回答207-210题。
The makers of Europe's toilet paper and other household paper goods are contributing todeforestation by failing to offer consumers enough recycled products, conservationists said recently.
"Everyday about 270,000 trees are effectively flushed down the toilet or end up as garbagearound the world; such a use of the forests is both wasteful and unnecessary," said Duncan Poundof WWF, formerly known as the World Wildlife Fund.
According to a WWF study, the five biggest manufacturers of disposable paper products inEurope are Procter and Gamble, SCA, Kimberly Clark, Mesa Tissue and Georgia Pacific, whichcontrolabout 70 percent of European market. The vast majorityof their products contain"alarmingly low levels" of recycled fibers, it said.
That means that"virgin fibers" extracted from natural forests and tree plantations around theworld"end up as waste without the consumer's knowledge, ” the Switzerland-based internationalconservation group said in this communique.
"Consumers have no idea that they may be threatening the world's forests when they go to thebathroom, "said Pollard, who heads the WWF program on European forests.
"The manufactures claim that retailers mainly want non-recycled products because that is whatconsumers choose." the WWF said.
"It's a myth that recycled tissue products are not of good quality." Pollard said.
The European tissue business is worth around 8.5 billion euros(10 billion dollars) annuallyand accounts for 26 percent of global consumption.
Each European uses on average 13 kilos of paper products per year, the WWF said.
The WWF has asked the companies to better inform consumers about how much of theirhousehold paper goods are made with recycled fibers and to advise them to buy bounds of recycledtoilet paper and tissues.
What does the underlined part"end up as waste without the consumer's knowledge" mean ?__________

A.Consumers waste "virgin fibers" because they lack knowledge
B.Consumers don't waste "virgin fibers" without knowledge
C.Consumers stopped using "virgin fibers" as waste because of knowledge
D.Consumers waste "virgin fibers" without know it

答案：D

解析：

根据文章第五段Pollard说的话，即“Consumers have nO idea that they may be threateningthe world’s forests when they go to the bathroom，”可知，是因为消费者自身没有意识到自己行为的后果，所有他们才这样浪费“原生纤维”。故选D。
