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.Which country is the biggest consumer of petroleum?
A: The United States.
B: Russia.
C: Norway.
D: Venezuela.答案：A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。 -

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.“…we will need to cure our addiction to oil.”Why does the author say so?
A:Most of the energy on Earth comes from the Sun.
B: Oil supply is increasing all the time.
C: Demand for oil is increasing all the time.
D: Oil supply is decreasing.答案：D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。 -

New Foods and the New World
In the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.
According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.“Some”in“some still exist today”(Para. 1)means______.
A:some cocoa trees
B: some chocolate drinks
C: some shops
D: some South American Indians答案：C解析：细节题。第一段第一句： In the last 500 years , nothing about people—not their clothes,ideas , or languages—has changed as much as what they eat.（在过去的500年中，没有任何关于人类的东西，如他们的衣服，观点或语言，会像他们吃的食物变化那么大）同时使用比较级和否定词表示最高级，意思恰恰就是A选项的内容。
细节题。从第一段最后两句话：London shops where chocolate drinks were served became important meeting places. Some still exist today.（在伦敦，供应巧克力饮料的店铺成为了重要的聚会地点。直到今天还存在一些这样的店铺）可以推断这里的some指的就是London shops。
细节题。第二段第三句：Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “ Potato Famine ” of 1845～1846.（爱尔兰人非常依赖土豆，在1845年到1846年期间的土豆饥荒中成千上万的爱尔兰人由于土豆欠收而挨俄）。强调the crop failed , the crop即potato。 A项没有说明土豆欠收这个关键事实；B项是starve导致的结果，并非原因;C项文章并未提及。
细节题。根据第三段倒数第二句：But it is native（本土的、当地的）to Ethiopia．句中it即指coffee，意思是咖啡最早产自埃塞俄比亚。A、B项和But it is native to Ethiopia矛盾；根据第三段最后一句：Arabs最早将咖啡制作为饮品。可以推断D是错误的。
推断题。第三段最后一句：It ( coffee ) was first made into a drink by Arabs during the 1400's.最后一段讲述这个阿拉伯传说就是为了证明阿位伯人首先发明了咖啡这种饮品，即D选项的内容。 -

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。 -

New Foods and the New World
In the last 500 years,nothing about people—not their clothes,ideas,or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians .The Spanish introduced it to the rest of the world during the 1500's .And although it was very expensive,it quickly became fashionable.In London,shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the New World. Around 1600,the Spanish brought it from Peru to Europe,where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the“Potato Famine”of 1845—1846,and thou- sands more were forced to emigrate to America.
There are many other foods that have traveled from South America to the Old World. But some others went in the opposite direction. Brazil is now the world's largest grower of coffee,and coffee is an important crop in Colombia and other South American countries.But it is native to Ethiopia. It was first made into a drink by Arabs during the 1400's.
According to an Arabic legend,coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berries on a coffee bush.He tried one and experienced the “wide-awake”feeling that one-third of the world's population now starts the day with.The Arabic legend is used to prove that
A:.coffee was first discovered by Kaldi
B: coffee was first discovered by Kaldi's goats
C:.coffee was first discovered in south American countries
D: coffee drinks were first made by Arabs答案：D解析：细节题。第一段第一句： In the last 500 years , nothing about people—not their clothes,ideas , or languages—has changed as much as what they eat.（在过去的500年中，没有任何关于人类的东西，如他们的衣服，观点或语言，会像他们吃的食物变化那么大）同时使用比较级和否定词表示最高级，意思恰恰就是A选项的内容。
细节题。从第一段最后两句话：London shops where chocolate drinks were served became important meeting places. Some still exist today.（在伦敦，供应巧克力饮料的店铺成为了重要的聚会地点。直到今天还存在一些这样的店铺）可以推断这里的some指的就是London shops。
细节题。第二段第三句：Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “ Potato Famine ” of 1845～1846.（爱尔兰人非常依赖土豆，在1845年到1846年期间的土豆饥荒中成千上万的爱尔兰人由于土豆欠收而挨俄）。强调the crop failed , the crop即potato。 A项没有说明土豆欠收这个关键事实；B项是starve导致的结果，并非原因;C项文章并未提及。
细节题。根据第三段倒数第二句：But it is native（本土的、当地的）to Ethiopia．句中it即指coffee，意思是咖啡最早产自埃塞俄比亚。A、B项和But it is native to Ethiopia矛盾；根据第三段最后一句：Arabs最早将咖啡制作为饮品。可以推断D是错误的。
推断题。第三段最后一句：It ( coffee ) was first made into a drink by Arabs during the 1400's.最后一段讲述这个阿拉伯传说就是为了证明阿位伯人首先发明了咖啡这种饮品，即D选项的内容。 -

Where Did the Earth's Water Come From?
Earth is located within the"snow line"of the solar system,the region closest to the Sun where H2 0 is primarily in liquid or gaseous form,if at all.______(46)The snow line phenomena is reflected in the water content of planets like Mercury,Venus,and Mars. Water is absent on Mercury.On Venus,H2O only exists as a trace element in the atmosphere.Mars only has a thin veneer of ice in its polar regions.In general,water is rare within the snow line.
Why does Earth have so much water relative to the other inner planets?71%of the surface is covered in the oceans,more than half of which is deeper than 3,000 meters,with an approximate total volume of 1.3 billion cu km.______(47)
There are various theories as to where all the Earth's water came from,but several theories have fared better than the others.______(48)When the Earth was in the process of forming,with a radius just 40%smaller than at present,it would have had enough gravity to hold on to a tenuous atmosphere with water vapor. The first water vapor on the planet would have come from the planet's internals,where volatile(low weight)chemicals would have a tendency to float to the top,and heavy chemicals(iron and nickel)would sink.
Though the first of Earth's water came about through volcanism,this alone probably didn't produce enough to form stable pools on the surface.______(49)Comparing the isotope ratios of water on Earth and water from comets and asteroids has revealed that the majority of the Earth's water comes from asteroids.
Throughout its history,Earth's water has increased in volume due to biological processes. In the early seas of Earth,hydrogen sulfide would have been in great supply,which,when reacted with carbon dioxide from the atmosphere during photosynthesis in sulfide-reducing bacteria,would have produced hydrogen,sulfur,and water.______(50)________（46）
A: More water was added to the planet during several hypothesized large impacts from asteroids from the outer asteroid belt.
B:We know that the oceans existed as early as 100 million years after the formation of the Earth.
C:Still,the oceans only make up 0.023%of the Earth's total mass.
D:Astronomers say Earth s water may have come from space.
E:The snow line is located in the outerasteroid belt,between the orbits of Mars and Jupiter.
F: Many geologists believe that the majority of Earth's water generated through this process.答案：E解析：文中第一段第一句提到了snow line，接下来的依据肯定还是要对snow line进行进一步说明，而选项中，只有E选项提到了snow line，所以选择E。
文中第二段主要说明地球上的水占的比重，而只有C选项是对这一主题进行说明，所以选择C。
根据后一句When the Earth was in the process of forming可以得知，该段是在讲述地球的形成历史，B选项We know that the oceans existed as early as 100 million years after the formation of the Earth也是在讲述地球形成的历史，所以选择B。
后一句：Comparing the isotope ratios of water on Earth and water from comets and asteroids has revealed that the majority of the Earth's water comes from asteroids．通过把地球上水的同位素和小行星以及彗星上的水的同位素进行比较，发现地球上的水主要来自小行星。可以推断出，该句要讲述地球上的水与太空中小行星的关系，所以A选项正确。
文中的最后一段主要是讲地球上水的来源。前一句：In the early seas of Earth,hydrogen sulfide would have been in great supply,which,when reacted with carbon dioxide from the atmosphere during photosynthesis in sulfide-reducing bacteria,would have produced hydrogen , sulfur , and water．在地球早期的海洋中，硫氢化合物非常丰富，在去硫细菌的光合作用的影响下，它与大气层中的二氧化碳产生化学反应，产生大量的氢、硫，以及水。这是地球自身产生的水，而F选项Many geologists believe that the majority of Earth's water generated through this process(许多地理学家认为地球上水的产生主要通过这一进程实现）正好承接前一句，所以F选项正确。 -
