The Science of the Future
Until recently,the"science of the future"was supposed to be electronics and
artificial intelligence.Today it seems more and more likely that the next great
breakthroughs in technology will be brought through a combination of those two sciences
with organic chemistry and genetic engineering.This combination is the science of
biotechnology.
Organic chemistry enables us to produce marvelous synthetic（合成的）materials.
However,it is still difficult to manufacture anything that has the capacity of wool to conserve
heat and also to absorb moisture.Nothing that we have been able to produce so far comes
anywhere near the combination of strength,lightness and flexibility that we find in the bodies
of ordinary insects.
Nevertheless,scientists in the laboratory have already succeeded in"growing"a
material that has many of the characteristics of human skin.The next step may well be
"biotech hearts and eyes"which can replace diseased organs in human beings.These will
not be rejected by the body,as is the case with organs from humans.
The application of biotechnology to energy production seems even more promising.In
1 996 the famous science-fiction writer,Arthur C. Clarke,many of whose previous
predictions have come true,said that we may soon be able to develop remarkably cheap
and renewable sources of energy.Some of these power sources will be biological.Clarke
and others have warned us repeatedly that sooner or later we will have to give up our
dependence on non-renewable power sources.Coal,oil and gas are indeed convenient.
However,using them also means creating dangerously high levels of pollution.It will be
impossible to meet the growing demand for energy without increasing that pollution to
catastrophic（灾难性的）levels unless we develop power sources that are both cheaper and
cleaner.
It is attempting to think that biotechnology or some other"science of the future"can
solve our problems.Before we surrender to that temptation we should remember nuclear
power.Only a few generations ago it seemed to promise limitless,cheap and safe energy.
Today those promises lie buried in a concrete grave in a place called Chernobyl,in the
Ukraine.Biotechnology is unlikely,however,to break its promises in quite the same or
such a dangerous way.What do we learn from the last paragraph?
A:Biotechnology can solve all our future energy problems.
B:Biological power is cheaper than nuclear power.
C:Biological power may not be as dangerous as nuclear power.
D:Biological power will keep all its promises.答案：C解析： -

Renewable Energy Sources
Today petroleum（石油）provides around 40% of the world's energy needs, mostly fuelling automobiles .Coal is still used,mostly in power stations,to cover one-quarter of our energy needs, but it is the least efficient, unhealthiest and most environmentally damaging fossil fuel（矿物燃料）.Natural gas reserves could fill some of the gap from oil,but reserves of that will not last into the 22nd century either. Most experts predict we will exhaust easily accessible reserves within 50 years. Less-polluting renewable energy sources offer a more practical long-term energy solution. "Renewable"refers to the fact that these resources are not used faster than they can be replaced.
Hydroelectric（水力发电的）power is now the most common form of renewable energy , supplying around 20% of world electricity.China's Three Gorges Dam is the largest ever. At five times the size of the U. S. 's Hoover Dam,its 26 turbines (涡轮机）will generate the equivalent energy of 18 coal-fired power stations. It will satisfy 3%of China's entire electricity demand.
In 2003,the first commercial power station to use tidal（潮汐的）currents in the open sea opened in Norway. It is designed like windmill（风车）,but others take the form of turbines.
As prices fall,wind power has become the fastest growing type of electricity generation-quadrupling（翻两番）worldwide between 1 999 and 2005 . Modern wind farms consist of turbines that generate electricity. Though it will be more expensive,there is more than enough wind to provide the world's entire energy needs.Wind farms come in onshore and offshore forms. They can often end up at spots of natural beauty,and are often unpopular with residents. And turbines are not totally harmless-they can interfere with radar,alter climate and kill sea birds.Scotland is building Europe's largest wind farm,which will power 200 ,000 homes. The U.K. 's goal is to generate one-fifth of power from renewable sources,mainly wind,by 2020 .But this may cause problems, because wind is unreliable.According to the passage,which of the following is the most polluting energy resource?
A: Petroleum.
B: Coal.
C: Natural gas.
D: Water.答案：B解析：文章第一段第二句话指出，煤炭尽管还在被大量地使用，但它是效率最低的，最有害健康和环境的燃料。这样看来煤炭就是污染最大的能源，选项B正确。
这道题的答案非常明确，在第二段第二句话“China's Three Gorges Dam is the largest ever"。这里ever表示直至目前世界上所建的水库中，三峡水库是最大的。
题目中take the lead是“带头”的意思，文中第三段指出2003年世界上第一家使用潮汐发电的电厂在挪威开始投产，因而挪威带头使用潮汐发电。
文章最后一句话指出英国到2020年五分之一的电力来自风力发电的目标会产生问题，因为风是不稳定、不可靠的（unreliable)，本题正确答案为B。
文章最后一段倒数第二句话明确指出可再生资源（renewable sources）主要是风，所以本题非常简单，正确选项是A。 -

Green Energy
1.Green energy is energy that is produced in a manner that has, less of a negative impact to the environment than energy sources like fossil fuels,which are often produced with harmful side effects."Greener" types of energy that often come to mind are solar,wind,geothermal and hydro energy.There are several more,even including nuclear energy,that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.
2.The goal of green energy is generally to create power with as little pollution as possible produced as a by-product. Every form of energy collection will result in some pollution,but those that are green are known to cause less than those that are not. Most people who advocate greener sources of energy claim that the result of worldwide use of green energy will result in the ability to preserve the planet for a longer time.Greenhouse gases,a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming,or the process of the Earth heating up at an accelerated pace.
3.It is not completely necessary for green energy sources to come from places like solar or wind fields,which are examples of green"power plants".A green energy source can be a building that is designed in a way that it keeps itself cool in the daytime and heated in the night through its architectural design rather than having an air-conditioning or a heating system. The conservation of energy through architectural（建筑学的）design becomes, itself, a green energy source. Similarly, many sources of green energy can come directly from the area in which the energy is needed rather than from an outside source.
4.One of the goals of green energy technology is to take existing fossil fuel energy technology and clean it up so it is produced more cleanly. One such case is that of clean coal technology,where scientists are trying to find ways to extract energy from coal and other fossil fuels without all of the harmful side effects.The success of such these types of green energy depend upon the ability to extract harmful by-products from fossil fuels while not only being energy efficient,but by being cost efficient as well.Nuclear energy is sometimes considered a green energy source because of its______.
A:global warming
B:carbon emission
C:lower waste output
D:a green energy source
E:fossil fuels
F: clean fuels答案：C解析：文中第一段第一句中Green energy is energy that is…这种表述方法符合科学说明文的记叙方式，首先对一个名词进行科学定义，所以本题答案为D。
文中第二段第二句：Every form of energy collection will result in some pollution, but those that are green are known to cause less than those that are not．任何形式的能源收集都会产生一定程度的污染，但是绿色能源比其他能源造成的污染要少。可以推测出这一段是在讲绿色能源的优点，也就是说为什么要发展绿色能源，所以选择A。
文中第三段第一句：It is not completely necessary for green energy sources to come from places like solar or wind fields．可以得出，本段主要讲述了我们传统认为的新能源，还有其他种类的新能源，所以选择F。
文中第四段第一句：One of the goals of green energy technology is to take existing fossil fuel energy technology and clean it up so it is produced more cleanly．可以得出，该段主要是在讲新能源的目标和意义。
第一段最后一句：There are several more, even including nuclear energy, that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil．可知，核能经常被视作绿色能源，因为相比煤和石油，它的能源输出效率更高。由此可以得出选项C正确。
文中第二段最后一句：Greenhouse gases, a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming,or the process of the Earth heating up at an accelerated pace.温室气体，一种诸如化石能源的传统能源产生的副产品被认为会导致全球变暖，甚至使地球自转速度加快。因此可以得出A选项正确。
第三段最后两句：The conservation of energy through architectural design becomes,itself,a green energy source .Similarly,many sources of green energy can come directly from the area in which the energy is needed rather than from an outside source．通过自身的建筑设计来保存能源本身就是一种绿色能源的来源。同样道理，许多绿色能源可以直接来源于有能源需求的地区内部而不是外部。由此可以得出D选项正确。
最后一段最后两句：The success of such these types of green energy depend upon the ability to extract harmful by-products from fossil fuels while not only being energy efficient, but by being cost efficient as well．这些清洁能源技术的成功取决于人们从化石燃料中排除有害副产品、高效利用能源、同时降低成本的能力。由此可以得出E选项正确。 -
第8题：
问答题If increased income is spent on more and larger automobiles, larger houses, and increased consumption of other material goods, the results could cause catastrophic resource exhaustion, and pollution. Take the increase of the consumption of oil for instance. The consumption is so huge that the oil reserves might last only a decade or two if not supplemented by imports.Ten years ago it appeared that nuclear power would solve the anticipated energy crisis. Although supplies of uranium fuel were known to be limited and might become exhausted in half a century, the nuclear power plant has for a long time been a favorite project. But work on it has met with grave problems. The fear of possible atomic explosion and the problem of disposing of polluting byproduct waste have slowed down the construction of further nuclear plants. Eventually atomic technology may be able to control these problems, but at present there seems to be little agreement along atomic scientists about when this can be achieved.正确答案：
随着收入的增加,人们会购买更多、更大型的轿车、更宽敞的房子,消费更多的其他商品,这就必然导致毁灭性的资源枯竭和污染。以原油消费的增长为例,原油消耗量巨大,如不进口原油来做补充的话,那么石油储量恐怕只够维持一、二十年了。
十年前,使用核能似乎能够解决预料会发生的能源危机。尽管大家知道铀燃料的供应是有限的,可能在半个世纪内耗尽,核能发电站多年来却一直倍受推崇。然而,核能发电站的工作已面临严峻的问题。人们心中的恐惧和面临的难题减缓了进一步建造新核电站的步伐:人们担心核爆炸;面临着污染性废料难以处理的问题。这些难题最终可以靠发展原子能技术来解决的。可是在目前,原子能科学家们对于何时才能实现这种可能性,尚难达成一致意见。解析： 暂无解析 -

D.Energy-security concerns are a priority.答案：B解析：推理题。本文的中心思想是能源供应乃能源问题的重中之重，如果没有了可供人们使用的能源，保护环境也就失去了意义。故本题选B。参考译文：安全供应是能源政策的首要议题。世界经济论坛最近对60多位能源行业领袖进行了调查，其中包括大公司首席执行官和政府高级官员。从伊拉克战争到尼日利亚和委内瑞拉的罢工，再到壳牌估计储量的削减，再到人们对新发现石油数量不断减少的担忧，地缘政治动荡已将油价推升至创纪录高点。1973年和1979年的石油危机对石油价格产生了永久的影响，如今同样的事情可能会再次发生——这足以让我们集中精力确保石油供应，并找到切实可行的石油替代品。对安全的担忧迫使他们做出艰难的选择。历史表明，政策制定者在考虑社会环境问题之前会优先考虑价格和供应，这遵循了马斯洛金字塔的基本规则。马斯洛金字塔理论是由美国心理学家亚伯拉罕·马斯洛在20世纪50年代提出的，用来解释正常人类的动机。正如马斯洛所说，一个缺乏食物、爱和尊重的正常人“对食物的渴望可能比对其他任何东西都强烈”。听起来很简单，但这个想法对于解释当前社会和环境争议性能源的复苏，尤其是煤炭、核能和大型水电的复苏，大有裨益。复苏的迹象随处可见。布什政府的能源计划将促进核技术和清洁煤的研究。中国计划到2020年将核电发电量从目前的1.5%提高到4%，法国国有电力公司(法国电力公司)刚刚再次确认其对核能的承诺，并将建造欧洲压水堆的前身。刚果河上新建大型水电站英戈大坝的计划，这些都反映了全球对大型水电项目的兴趣正在复苏的趋势。地缘政治推动了这些趋势。核燃料可以高效地储存，所有大陆都蕴含着丰富的煤炭资源，水电是本地的资源，因此所有这些资源都能以某种方式免受地缘政治动荡的影响。石油以外的多元化需求，也迫使供应商重新考虑天然气。长期以来，天然气一直是能源家族中的“穷亲戚”。卡塔尔第二任副总理兼能源部长阿提亚说，卡塔尔曾经对上世纪80年代发现的是天然气而不是石油感到失望，然后花了20年时间才认识到天然气的价值。如今，液化天然气成本的下降正使其更容易运往日益增长的世界市场，使其成为一种日益全球化和有价值的大宗商品。世界经济论坛最近对能源行业的首席执行官和政府监管机构进行的一项调查显示，47%的受访者认为天然气是最有希望替代石油的能源，另有40%的人认为煤炭是最有希望替代石油的能源。通常，对安全和环境的担忧会将决策者推向相反的方向。核能和天然气受益于对气候变化的讨论，而煤炭和核能则受益于对能源安全的担忧。天然气正在取得进展，部分原因是它燃烧干净，但同时它也面临着与石油类似的地缘政治上的安全担忧：40%以上的资源集中在俄罗斯、卡塔尔和伊朗。只要有关供应安全主导的政策议程，一旦是关于高阶问题的达成，包括《京都议定书》在内的协议，一些国家就会面临困难。那些还没有获得可负担的电力供应的国家将致力于在达成环境议程之前寻找低廉的解决方案。如果建立联盟可能会产生更直接的影响。正如马斯洛所预言的，人们会先担心餐桌上的食物，然后才会担心盘子有多干净，或者谁会和他们一起吃饭。印度的甘地利用这一观点进行阐述，她将贫困称为终极污染物，并将其置于能源领域内：如果所有人都有脏乱的煤炭，那么他们就会烧煤。当简单的解决方案更有前景时，环保主义者往往会推动昂贵的高科技。例如，阿联酋国家石油公司首席执行官、论坛成员之一苏尔坦曾表示，液化天然气尽管位置偏远，但其能够满足快速、廉价和相对清洁的能源需求。因此，供应不仅仅是大型石油公司首席执行官们考虑的首要问题。为了实现目标，环保主义者也应该把供应放在首位，因为当事态严重时，能源安全将成为最大的问题。 -

第22题：
单选题After several nuclear disasters, a _____ has raged over the safety of nuclear energy.Aquarrel
Bsuspicion
Cverdict
Dcontroversy
正确答案： D解析：
句意：几次核灾难激起了一场关于核能的安全性的争论。controversy争论，辩论，所涉及的特别是社会、道德或政治问题。nuclear disasters和safety of nuclear energy形成对立关系，这种对立引起争论，因此D为正确答案。quarrel争论，强调以吵架、发生口角等形式引起的争论，不够正式。suspicion怀疑。verdict陪审团的判决，决定。 -
第23题：
单选题It can be concluded from the passage that ______.Ait is hopeful to bring solar energy into average households
Bit is feasible to use nuclear energy to run home appliances
Cit is economical to use water to heat houses
Dit is possible to use wind to power machines
正确答案： D解析：
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. -
