Energy and Public Lands

The United States boasts substantial energy resources.Federal lands provide a good deal of US energy
production,the US Department of the Interior manages federal energy leasing（租赁）,both on land and on
the offshore Outer Continental Shelf. Production from these sources amounts to nearly 30 percent of total
annual US energy production.
In 2000,32 percent of US oil,35 percent of natural gas,and 37 percent of coal were produced from
federal lands,representing 20,000 producing oil and gas leases and 135 producing coal leases.Federal lands
are also estimated to contain approximately 68 percent of all undiscovered US oil reserves and 74 percent of
undiscovered natural gas.
Revenues from federal oil,gas,and coal leasing provide significant returns to US taxpayers as well as
State Government.In 1999,for example,$553 million in oil and gas revenues were paid to the US Treasury,
and non-Indian coal leases accounted for over $304 million in revenues,of which 50 percent were paid to
State governments.Public lands also play a critical role in energy delivery.Each year,federal land managers
authorize rights of way for transmission lines,rail systems,pipelines,and other facilities related to energy
production and use.
Alternative energy production from federal lands falls behind conventional energy production,though the
amount is still significant. For example , federal geothermal（地热）resources produce about 7. 5 billion
kilowatt-hours（千瓦时）of electricity per year , 47 percent of all electricity generated from US geothermal
energy.There are 2,960 wind turbines on public lands in California alone,producing electricity for about
300 ,000 people. Federal hydropower（水电）facilities produce about 17 percent of all hydropower produced
in the United States.
Because of the growing US thirst for energy and increasing public unease with dependence on foreign oil
sources,pressure on public lands to meet US energy demand is becoming more intense.Public lands are
available for energy development only after they have been evaluated through the land use planning process.
If development of energy resources conflicts with management or use of other resources,development restric-
tions or impact moderation measures may be enforced,or mineral production may be banned altogether.
选项 What is the main idea of this passage?
A:Public lands play an important role in energy production.
B:Public lands are one of the main sources of revenues.
C:Public lands should be developed to ease energy shortage.
D:Public lands store huge energy resources for further development.
答案A
解析本文前四段都在从各个侧面强调公共土地在美国能源生产方面占有巨大的份额，最后 一段又讲对这些能源的开发需求，B、C、D三项都是文中某一段体现的观点，只有A项涵盖最 全面，故选A。
根据文章第二段最后一句“Federal lands are also estimated to contain approximately 68 percent of all undiscovered US oil reserves and 74 percent of undiscovered natural gas.”可知B 项正确。
根据文章第四段“For example”前的那句话“Alternative energy production from federal lands falls behind conventional energy production , though the amount is still significant.”可知答案。 though在此意为“然而”。
根据文章最后一段第一句话“Because of the growing US thirst for energy and increasing public unease with dependence on foreign oil sources,pressure on public lands to meet US energy demand is becoming more intense.”可知答案。
根据文章最后一段第二句话“Public lands are available for energy development only aftei they have been evaluated through the land use planning process.”可知答案。第三篇 本文介绍了蜜獾好奇、多变、凶狠的性格及其广泛的捕食对象、大面积的狩猎范围和松散的 家庭群落等内容。
