    Thirst for Oil
    Worldwide every day,we devour the energy equivalent of about 200 million barrels of oil. Most of the energy on Earth comes from the Sun. In fact enough energy from the Sun hits the planet's surface each minute to cover our needs for an entire year,we just need to find an efficient way to use it. So far the energy in oil has been cheaper and easier to get at. But as supplies dwindle,this will change,and we will need to cure our addiction to oil.
    Burning wood satisfied most energy needs until the steam-driven industrial revolution,when energy-dense coal became the fuel of choice. Coal is still used,mostly in power sta-tions,to cover one quarter of our energy needs,but its use has been declining since we star-ted pumping up oil. Coal is the least efficient,unhealthiest and most environmentally dama-ging fossil fuel,but could make a comeback,as supplies are still plentiful:its reserves are five times larger than oil's.
    Today petroleum,a mineral oil obtained from below the surface of the Earth and used to produce petrol,diesel oil and various other chemical substances,provides around 40% of the world's energy needs,mostly fuelling automobiles. The US consumes a quarter of all oil,and generates a similar proportion of greenhouse gas emissions.
    The majority of oil comes from the Middle East,which has half of known reserves. But other significant sources include Russia,North America,Norway,Venezuela and the North Sea. Alaska's Arctic National Wildlife Refuge could be a major new US source,to reduce reliance on foreign imports.
    Most experts predict we will exhaust easily accessible reserves within 50 years,though opinions and estimates vary. We could fast reach an energy crisis in the next few decades, when demand exceeds supply. As conventional reserves become more difficult to access,oth-ers such as oil shales and tar sands may be used instead. Petrol could also be obtained from coal.
    Since we started using fossil fuels,we have released 400 billion tonnes of carbon,and burning the entire reserves could eventually raise world temperatures by 13℃ .Among other horrors,this would result in the destruction of all rainforests and the melting of all
    Arctic ice.

    Which of the following statements is NOT meant by the author,according to the second paragraph?
    A:Wood was the fuel of choice before coal.
    B: The use of coal is declining.
    C: Coal is the most environmentally unfriendly fuel next to oil.
    D: Coal reserves are plentiful and will be likely to become the major fuel of choice.

    答案：C
    解析：
    题干意为“为什么作者说‘……我们需要改变我们对石油的依赖性’?”该题考查考生对短文中某个句子意思的理解，首先找到该句在短文中所在的语境：Worldwide ev-ery day,we devour the energy equivalent of about 200 million barrels of oil. Most of the en-ergy on Earth comes from the Sun. In fact enough energy from the Sun hits the planet's sur-face each minute to cover our needs for an entire year,we just need to find an efficient way to use it.So far the energy in oil has been cheaper and easier to get at. But as supplies dwindle, this will change, and we will need to cure our addiction to oil．第一段最后一句意为“但是当供应缩减时，情况就会改变，我们需要改变我们对石油的依赖性”。由此可知“我们需要改变我们对石油的依赖性”的原因是石油供应缩减，因此D项“石油供应在缩减”是答案。
    题干意为“依据第二段内容来看，下面哪项内容不是短文中的作者想要表达的意思？”利用备选项中的细节信息词/短语wood , fuel of choice , coal , use of coal , most envi-ronmentally unfriendly fuel,oil, coal reserves作为定位线索，在第二段中快速识别与选项分别对应的句子：Burning wood satisfied most energy needs until the steam-driven industrial revolution,when energy-dense coal became the fuel of choice．Coal is still used,mostly in power stations,to cover one quarter of our energy needs,but its use has been declining since we started pumping up oil. Coal is the least efficient, unhealthiest and most environmentally damaging fossil fuel,but could make a comeback,as supplies are still plentiful:its reserves are five times larger than oil's．定位线索词分散在整个段落中，因此需要理解整个段落的意思。第一句提到“在蒸汽工业革命时代，高能煤成为首选燃料之前，燃木能满足大部分能源需求”。这与A项“燃木是煤作为燃料之前的首选燃料”意义一致；第二句提到“自从我们开始大量开采石油后，煤的使用就已经在逐渐减少”，这与B项“煤的使用在减少”意义一致；第三句提到“煤是使用效率最低，最不卫生，最不环保的化石燃料”，这与C项“煤对环境的危害性仅次于石油”不一致：依据短文内容来看煤对环境的危害排在第一位。因此该题答案为C。
    题干意为“哪个国家是最大的石油消耗国？”利用题干及备选项中的细节信息词/短语country , the biggest consumer of petroleum , the United States , Russia , Norway,Venezuela作为定位线索，在第三段找到相关句：Today petroleum, a mineral oil obtained from below the surface of the Earth and used to produce petrol,diesel oil and various otherchemical substances,provides around 40% of the world's energy needs,mostly fuelling au-tomobiles. The US consumes a quarter of all oil,and generates a similar proportion of green-house gas emissions．相关句（第三段最后一句）提到“美国消耗了世界上1/4的石油”，而除此以外短文中没有再提到其他的石油消耗国了。虽然选项C涉及到的挪威，选项D涉及到的委内瑞拉，选项B涉及到的俄罗斯在短文中也出现了，但它们都是作为石油产地国出现的，因此这三个选项都不是答案。所以答案为A。
    题干意为“关于地球上的燃料储备，专家们是怎么说的？”利用题干及备选项中的细节信息词/短语experts,earth's fuel reserves,next 50 years, energy crisis,convention-al reserves, fuel demand作为定位线索，在第五段中找到相关句：Most experts predict we will exhaust easily accessible reserves within 50 years, though opinions and estimates vary. We could fast reach an energy crisis in the next few decades,when demand exceeds supply. As conventional reserves become more difficult to access,others such as oil shales and tar sands may be used instead. Petrol could also be obtained from coal．定位线索词集中出现在第五段中。该段第一句提到“大多数专家预测人类将轻而易举地在50年内消耗掉现在所有的石油储备”。这与A项“地球的石油储备在下一个50年间仍然还将够用”不一致；第二句“未来的几十年间，当能源供不应求时我们会很快陷入能源危机”，这与B项“将很快出现能源危机”意思一致，因此选项B是答案，同时该句意思与D项“燃料需求将下降”不一致：短文提及“供不应求”，这意味着对能源的需求将会增加，而不是下降；第四句提到“当常规能源不容易获得时，代之使用的可能是诸如油页岩和沥青砂等能源”，短文提到“常规能源不容易获得”，不是说“不能获得”，因此C项“很快将不能获得常规能源”与短文内容不一致。

    Energy and Public Lands

    The United States boasts substantial energy resources?Federal lands provide。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 ga9,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 demnand is becoming more intense.Public lands are
    available for energy development oniy after they have been evaivated through the land use planning process.
    If development of energy resources conflicts with management or use of other resources,development restric-
    lions or impact moderation measures may be enforced,or mineral production may he banned altogether.

    There is a mounting pressure on public lands to satisfy US energy demands because_______.
    A:many Americans are unhappy with energy development in foreign countries
    B:quite a few public lands are banned for energy development
    C:the U.S.is demanding more and more energy
    D:many Americans think public lands are being abused

    答案：C

  • 第10题：

    问答题
    Directions:In this section, there is one passage followed by 5 questions. Read the passage carefully, then answer the questions in a maximum of 10 words. Remember to write the answers on the Answer Sheet.　　Questions 1-5 are based on the following passage.　　Could the bad old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $26 a barrel, up from less than $10 last December. This near-tripling of oil prices calls up scary memories of the 1973 oil shock, when prices quadrupled, and 1979-1980, when they also almost tripled. Both previous shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time?　　The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the same time as winter grips the northern hemisphere, could push the price higher still in the short term.　　Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past.　　Rich economies are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production. For each dollar of GDP (in constant prices) rich economies now use nearly 50% less oil than in 1973. The OECD estimates in its latest Economic Outlook that, if oil prices averaged $22 a barrel for a full year, compared with $13 in 1998, this would increase the oil import bill in rich economies by only 0.25-0.5% of GDP. That is less than one-quarter of the income loss in 1974 or 1980. On the other hand, oil-importing emerging economies—to which heavy industry has shifted—have become more energy-intensive, and so could be more seriously squeezed.　　One more reason not to lose sleep over the rise in oil prices is that, unlike the rises in the 1970s, it has not occurred against the background of general commodity-price inflation and global excess demand. A sizable portion of the world is only just emerging from economic decline. The economist’s commodity price index is broadly unchanging from a year ago. In 1973 commodity prices jumped by 70%, and in 1979 by almost 30%.　　Questions:　　1．What is the main reason for the latest rise of oil price?　　2．What are the results of the 1970s’ oil shock?　　3．It can be inferred from the text that the retail price of petrol will go up dramatically if ________.　　4．According to the passage, reduction in oil consumption is due to ________, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries.　　5．According to the passage, compared with those in the 1970s, oil-price shocks are ________ now.

    正确答案：
    1.Reduction in supply. / Supply-cuts 依据文章第一段第二句话:“Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $26 a barrel, up from less than $10 last December”,可知答案为Reduction in supply或Supply-cuts。
    2.Double-digit inflation and global economic decline 文章第一段第四句话提到“Both previous shocks resulted in double-digit inflation and global economic decline”,其中both previous shocks指前文提到的1973年和1979到1980年间的oil shock,可知答案为Double-digit inflation and global economic decline。
    3.oil taxes rise 文章第三段第三句话提到“In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past”,意为:在欧洲,汽油的零售价中税占到五分之四,因此税的增加会导致汽油价格(成比例地)猛涨,而原油价格的变化带来的影响不会很大。由此可知如果油税上调,汽油零售价格将急剧上涨。因此答案为oil taxes rise。
    4.energy conservation 文章第四段第二句提到“Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption”,由此可知答案为energy conservation。
    5.less shocking 文章最后一段强调这次油价上涨与20世纪70年代的油价上涨不同,它并不是在普遍日用品价格上涨和全球需求过剩的背景下发生的,也就没有70年代那一次那么可怕,因此答案为less shocking。

    Thirst for Oil
    Worldwide every day,we devour the energy equivalent of about 200 million barrels of oil.
    Most of the energy on Earth comes from the Sun.In fact enough energy from the Sun hits the planet's surface each minute to cover our needs for an entire year,we just need to find an efficient way to use it. So far the energy in oil has been cheaper and easier to get at. But as supplies dwindle,this will change,and we will need to cure our addiction to oil.
    Burning wood satisfied most energy needs until the steam-driven industrial revolution,when energy-dense coal became the fuel of choice.Coal is still used,mostly in power stations,to cover one quarter of our energy needs,but its use has been declining since we started pumping up oil.
    Coal is the least efficient,unhealthiest and most environmentally damaging fossil fuel,but could make a comeback,as supplies are still plentiful:its reserves are five times larger than oil's.
    Today petroleum,a mineral oil obtained from below the surface of the Earth and used to pro- duce petrol,diesel oil and various other chemical substances,provides around 40% of the world's energy needs,mostly fuelling automobiles.The US consumes a quarter of all oil,and generates a similar proportion of greenhouse gas emissions.
    The majority of oil comes from the Middle East,which has half of known reserves.But other significant sources include Russia,North America,Norway,Venezuela and the North Sea.
    Alaska's Arctic National Wildlife Refuge could be a major new US source,to reduce reliance on foreign imports.
    Most experts predict we will exhaust easily accessible reserves within 50 years,though opinions and estimates vary.We could fast reach an energy crisis in the next few decades,when demand exceeds supply.As conventional reserves become more difficult to access,others such as oil shales and tar sands may be used instead.Petrol could also be obtained from coal.
    Since we started using fossil fuels,we have released 400 billion tonnes of carbon,and burn- ing the entire reserves could eventually raise world temperatures by 13℃．Among other horrors, this would result in the destruction of all rainforests and the melting of all Arctic ice.

    What do experts say about the earth's fuel reserves?
    A: The earth's fuel reserves will be accessible for the next 50 years.
    B: There will soon be an energy crisis.
    C: Conventional reserves will soon become inaccessible.
    D: Fuel demand will decline.

    答案：B
    解析：
    答案在第一段最后一句中。这里的supplies指oil supplies。


    短文第二段告诉我们，木材曾经是主要燃料来源，然后被煤所替代；自人们开始采油后，对煤的需求下降了，但因为煤的储量远大于石油，它可能又会成为主要燃料，尽管它对环境最具破坏力。所以A、B、D均是作者的意思，而C不是。next to oil除石油以外。


    文章的第三段说，美国消耗全世界1/4的石油。


    答案在第五段第二句中。该段第一句说，地球上的燃料储量将在50年内耗尽，所以A不是正确选项；第三句的意思是，常规燃料的获取将变得困难，而不是不可获得，所以C也不是正确选项;D明显不是作者的意思。


    选项B、C、D都是最后一段中所表达的意思，所以A是正确选项。

    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 pro-duced 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 undis-covered 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-India coal leases accounted for over$304 million in revenues,of which 50 percent were paid to State governments.

    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 demnand is becoming more intense.Public lands are
    available for energy development oniy after they have been evaivated through the land use planning process.
    If development of energy resources conflicts with management or use of other resources,development restric-
    lions or impact moderation measures may be enforced,or mineral production may he banned altogether.

    Public lands can be used for energy development when ________.
    A:energy development restrictions are effective
    B:federal land managers grant perrmssions
    C:they go through the land use planning process
    D:there is enough federal budget

    答案：C
    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 68percent 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 after they have been evaluated through the land use planning process.”可知答案。第二篇 本文通过一项实验向我们讲述了一个发现：人们会注意到他们需要和追求的东西且这一过程不涉及思考。

    录音中指出通过使用hybrid nanorod polymer composite可以极大降低利用太阳能的成本，虽然目前为止nanorod polymer cells的转换效率只是2%多一点，但是研究者相信效率能得到极大提高，由此可推断太阳能在普通家庭的使用是有望实现的。
    【录音原文】
    　　Millions of people around the world would like to heat their homes and run household appliances with solar power. But the cost of doing so puts it out of the question. The first problem is that the cells convert only 10％-15％of the radiation from the sun into energy. The second is that the photovoltaic (PV) material used is a form of silicon that has to be made under high vacuum conditions and heated in special kilns to 1.400℃. That makes photovoltaic solar cells horrendously expensive.
    　　How to bring the high costs down to a more manageable amount? One answer that is attracting attention is to use carbon “nanorods”, superstrong cylinders of carbon atoms that are 75, 000 times thinner than a human hair. If scientists succeed in their efforts, carbon-based solar cells could cost as little as a tenth of the price of today’s silicon-based versions.
    　　By placing the flexible nanorods in a polymer solution, researchers found it could produce a composite material that had the elasticity and pliability of plastic, but capable converting solar rays into electrical energy. Inorganic nanocrystals behave a lot like polymers. For instance, they can be processed while still in the form of a solution. Scientists had been working with plastics as an alternative to conventional solar cells, but found that they did not conduct electricity particularly well.
    　　Compared with the arduous process of fabricating conventional solar cells, making the hybrid nanorod polymer composite would be more like manufacturing cheap plastic laminates. That could solve the cost part of the solar energy equation. But what about the conversion efficiency? So far, the conversion efficiency of nanorod polymer cells has been little more than 2％. However, researchers are confident that the efficiency can be improved considerably.

  • 第22题：

    The Hallside site has been ______.
    A

    turned into a steelworks from a woodland and an energy park.

    B

    in use as an energy park .

    C

    disused for a long period of time .

    D

    out of use for a short period of time .


    正确答案： C
    解析：
    根据题干关键词Hallside site可定位到原文C和D段，C段中“Hallside’s closure in 1979 put an end to more than 100 years of steel production”，可知该厂与1979年倒闭，D段中“The site’s 30 hectares were left abandoned until 1990”，可知直到1990年该厂才开始重新使用。因此，可以得知从1979年到1990年该厂一致出于废弃状态，因此，C项的长期不被使用与该意相符，为正确选项。
