共用题干Where Has the Salt Come from?Every now and then,we meet a fact about our earth that makes us feel strange and no answer for the fact has yet been found.Such a fact is the existence of salt in the oceans. How did it get there?We simply do not know how the salt got into the ocean!We do know,of course,that salt is water-soluble,and so passes into the oceans with rainwater.The salt of the earth's surface is constantly being dissolved（溶解）and is passing into the ocean.But we do not know whether this can explain the huge quantity of salt in oceans.If all the oceans were dried up,enough salt would be left to build a wall 180 miles high and a mile thick. Such a wall would reach once around the world at the Equator（赤道）!The common salt that we all use is produced from seawater or the water of salt lakes, from salt springs（源泉）and from deposits of rock salt. The concentration（浓度）of salt in seawater ranges from about three percent to three-and-one-half percent. The Dead Sea, which covers an area of about 340 square miles,contains about 11,600,000,000 tons of salt!On the average, a gallon（加仑）of seawater contains about a quarter of a pound of salt.The beds of rock salt that are found in various parts of the world were all originally formed by the evaporation（蒸发）of seawater millions of years ago. It is believed that the thick rock-salt deposits were formed after about nine-tenth of theY volume of seawater had been evaporated.Most commercial salt is obtained from rock salt.The usual method is to drill wells（井） down to the salt beds. Pure water is pumped down（抽进去）through a pipe. The water dissolves the salt and it is forced through another pipe up to the surface.A:Right B:Wrong C:Not mentioned
共用题干第二篇Energy and Public LandsThe 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. Public lands can be used for energy development when_________________.A:energy development restrictions are effectiveB:federal land managers grant permissionsC:they go through the land use planning processD:there is enough federal budget
