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。 -

正确答案： B解析：
事实细节的找寻和判断。录音中提到东芝公司总裁对购买价格的看法是“…while the price might seem quite high, Toshiba had a lot of competition for the company and that the future growth and profit potential of the business made it the correct price”，可知虽然购买价格过于昂贵，但该公司面临大量的竞争，并且未来的发展和利润潜力也证实了这桩买卖还是合算的。分别对应选项A、B和C，而唯独没有提到选项D（被购买公司的巨大固有价值）的内容。 -

正确答案： A解析：
文章中指出美国中小学目前的政策及工资待遇往往更有利于水平一般的教师，并且倒数第三段最后一句提到“...these less-capable pedagogues settle in to provide many years of ineffectual instruction”，因此选项A的表述与文章内容不符。其他选项的内容在文中都有提及。 -

第12题：
单选题It can be concluded from information contained in the passage that the average temperature at an altitude of 1 kilometer above the Earth is about _____.A15℃
B9℃
C2.5℃
D-12℃
正确答案： A解析：
根据文中第三段第一句的信息：“Under present conditions a temperature of -18℃ can be observed at an altitude of 5 to 6 kilometers above the Earth. Below this altitude (called the radiating level), the temperature increases by about 6℃ per kilometer approaching the Earth’s surface where the average temperature is about 15℃”可以推断，海拔一千米处的平均气温大约为12℃以下，选项B 9℃最接近，因此选择B项。 -

第16题：
单选题Which of the following is true according to the passage?AThe drive weighed a full ton.
BThe IBM research center planned to make a music player.
CIts 24 spinning disks could store only 5 megabytes of information.
DThe price for renting the RAMAC was $260,000 a year.
正确答案： A解析：
事实细节的找寻和判断。从录音中提到的“The RAMAC, designed in Big Blue’s San Jose, Calif., research center”，可知RAMAC是在Big Blue’s San Jose, Calif., research center 制造的，而非B项提到的IBM research center。此外，C项中的24 spinning disks与录音中its 50 spinning…disks的内容不符。关于租用该设备的价格，录音中提到“to lease it you’d pay about $250,000 a year in today’s dollars”，而选项D则指出租赁价格为$260,000，显然与录音原文不符。A项的内容在录音中直接出现过。
【录音原文】
On September l3, 1956, IBM shipped the first unit of the RAMAC, in other words, Random Access Method of Accounting and Control. The RAMAC, designed in Big Blue’s San Jose, Calif., research center would have made a lousy music player. The drive weighed a full ton, and to lease it you’d pay about $250, 000 a year in today’s dollars. Since it required a separate air compressor to protect the two moving “heads” that read and wrote information, it was noisy. The total amount of information stored in its 50 spinning iron-oxide-coated disks—each of them a pizza-size 24 inches—was 5 megabytes. -

单选题It can be inferred from the passage that the author would be most likely to agree with which of the following statements about schools?AThey should present political information according to carefully planned, schematic arrangements.

CThey are ineffectual to the degree that they disregard adolescents’ political naves.
DBecause they are subsidiary to government, their contribution to the political understanding of adolescents must be limited.
正确答案： B解析：
分析推理题。首先，由第二段第四句可知，作者将学校和教会作为组成政治体系的一个例子。然后，由该段第五、六句可知，青少年幼稚的政治知识源自对这一政治体系的不完全理解。由此可知，作者认为学校本身就是社会政治体系中的组成部分，学生从中可以学会理解这一体系，故B项为正确答案。 -
