Electromagnetic Energy
1 White light seems to be a combination of all colors.The energy that comes from a source of light is not limited to the kind of energy you can see.Heat is given off by a flame or an electric light.On a cloudy day it is possible to get a sunburn even though you feel cool.Visible light and the kinds of energy that produce warmth and sunburn are examples of electromagnetic energy.
2 The sun is 93 million miles from the earth.Yet we can use energy from the sun because electromagnetic energy travels through space.
3 Many other kinds of energy are also types of electromagnetic energy.Radio,television,and radar signals travel from transmitters to receivers as low-energy electromagnetic waves.Infrared（红外线的）radiation is an electromagnetic wave.When it is absorbed by matter,heat is produced.Waves of infrared and visible light have more energy than waves of radio,television,or radar.Ultraviolet rays（紫外线）and X-rays are electromagnetic waves with even greater amounts of energy.Infrared radiation is used in cooking food and heating buildings. Sunlight and electric lights are part of our requirements for normal living.Ultraviolet radiation is useful in killing certain disease organisms.X-rays and gamma rays have so much energy that they travel through solid objects. They can be used to detect and treat cancer.X-rays are used in industry to find hidden cracks in metal,and in medicine to reveal broken bones.
4 Usually we use electricity to generate electromagnetic energy.The source of most of our energy is the sun.Heat from the sun causes water to evaporate.When the water falls to the earth as rain,some of it is trapped behind dams and then used to operate electric generators.Other generators are powered by coal,but the energy stored in coal came from the sun,too.
5 Until recently,the source of the tremendous amount of energy given off by the sun was a puzzle.If the sun depended on chemical reactions,it would have used up all its energy long ago.Experiments with electromagnetic radiation led to the theory that mass can be converted into energy.About forty years after the theory was proposed , nuclear energy was harnessed（利用）by man.Chemical energy comes from electron （电子）rearrangement.Nuclear energy comes from a change in the nucleus of an atom.Compared with chemical reactions,nuclear reactions release millions of times more energy per pound of fuel.We now believe that the sun's energy comes from the nuclear reactions in which hydrogen is changed into helium（氦）.
6 Nuclear energy is beginning to compete with coal as an economical source of'power to generate electricity.It is also being used to operate engines in large ships.Scientists continue to seek new and better methods of obtaining and using energy.Paragraph 4______
A:Nuclear Reactions as the Lasting Source of the Sun's Energy
B:The Most Important Source of Energy
C:Types of Electromagnetic Energy
D:The Machines Used for Energy Generation
E:Seeking New Sources of Energy
F:The Use of Ultravio1et Radiation in Medicine答案：B解析：通读文章可知，第三段第一句是段落主题句，紧接着围绕第一句进行了具体阐述，根据第一句中出现的“types of electromagnetic energy”可知，第三段主要讲述几种不同种类的电磁能，应选择C项。
根据第四段第一、二句可知，我们通常用电来生成电磁能，使用的很多能源都来自太阳。紧接着又表明，水能源于来自太阳的热能，煤储存的能量也是来自太阳。因此不难得出，第四段讲的是能量最重要的来源，即太阳。
第五段开头提到太阳能的来源仍是个谜，随后对此进行了分析，最后得出太阳能来自核反应释放的能量。由此可知，第五段主要讲的是，氢原子转变为氦原子的核反应释放的能量是太阳能的来源。几个选项中只有A项提到核反应是太阳能的持久来源，因此选择A项。
通读文章可知，第六段的最后一句是主题句。这句话的大意是：科学家正继续在寻找更好的新方法来获取并使用能源。几个选项中只有E项与之契合，因此选择E项。
根据第一段第四句可知，你即便在感到凉爽的阴天，也有可能被阳光灼伤，因此选择B项。
根据第三段第三、四句可知，红外线是电磁波，当它被物质吸收时，会产生能量。
根据第三段倒数第二、三句可知，X射线和伽马射线之所以能用来探测和治疗癌症，是因为具有很多能量的x射线和伽马射线能穿透固体。

第3题：
Text 3 Drones,originally developed for military purposes,weren't approved for commercial use in the United States until 2013.When that happened,it was immediately clear that they could be hugely useful to a whole host of industries-and almost as quickly,it became clear that regulation would be a problem.The new technology raised multiple safety and security issues,there was no consensus on who should write rules to mitigate those concems,and the knowledge needed to develop the rules didn't yet exist in many cases.In addition,the little flying robots made a lot of people nervous.Such regulatory,logistical,and social barriers to adopting novel products and services are very common.In fact,technology routinely surpasses society's ability to deal with it.That's partly because tech entrepreneurs are often insouciant about the legal and social issues their innovations birth.Although electric cars are subsidized by the federal govemment,Tesla has run afoul of state and local regulations because it bypasses conventional dealers to sell directly to consumers.Facebook is only now facing up to major regulatory concerns about its use of data,despite being massively successful with users and advertisers.It's clear that even as innovations bring unprecedented comfort and convenience,they also threaten old ways of regulating industries,running a business,and making a living.This has always been true.Thus early cars weren't allowed to go faster than horses,and some 19th-century textile workers used sledgehammers to attack the industrial machinery they feared would displace them.New technology can even upend social norms:Consider how dating apps have transformed the way people meet.Interestingly,the same institutional disorder that pervades nascent industries such as drones and driverless cars is something I've also seen in developing countries.And strange though this may sound,I believe that tech entrepreneurs can leam a lot from business people who have succeeded in the world's emerging markets.Entrepreneurs in Brazil or Nigeria know that it's pointless to wait for the govemment to provide the institutional and market infrastructure their businesses need,because that will simply take too long.They themselves must build support structures to compensate for what Krishna Palepu and I have referred to in earlier writrngs as"institutional voids."They must create the conditions that will allow them to create successful products or services.
Entrepreneurs have to build support structures by themselves because_____A.there exist institutional voids led by development
B.they are eager to create successful products
C.it is necessary for creating good services
D.they may be more efficient than govemment答案：D解析：事实细节题。根据定位词定位到最后一段。原文指出，巴西或尼日利亚的企业家知道，等待政府为他们的企业提供所需的机构和市场基础设施是没有意义的，因为这将花费太多时间，所以他们必须自己建立支撑结构，故D项为正确选项。【干扰排除】由以上分析可知，A、B、C项均与题干无关，故排除。 -

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.Greenhouse gases are thought to be causing______.
A:global warming
B:carbon emission
C:lower waste output
D:a green energy source
E:fossil fuels
F: clean fuels答案：A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。 -

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： A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. -

2 The sun is 93 million miles from the earth.Yet we can use energy from the sun because electromagnetic energy travels through space.
3 Many other kinds of energy are also types of electromagnetic energy.Radio,television,and radar signals travel from transmitters to receivers as low-energy electromagnetic waves.Infrared（红外线的）radiation is an electromagnetic wave.When it is absorbed by matter,heat is produced.Waves of infrared and visible light have more energy than waves of radio,television,or radar.Ultraviolet rays（紫外线）and X-rays are electromagnetic waves with even greater amounts of energy.Infrared radiation is used in cooking food and heating buildings. Sunlight and electric lights are part of our requirements for normal living.Ultraviolet radiation is useful in killing certain disease organisms.X-rays and gamma rays have so much energy that they travel through solid objects. They can be used to detect and treat cancer.X-rays are used in industry to find hidden cracks in metal,and in medicine to reveal broken bones.

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.Paragraph 3______
A:Why Do We Develop Green Energy?
B:What Is the Goal of Green Energy?
C:What Is the Weakness of Green Energy?
D:What Is a Green Energy?
E:How Much Does the Green Energy Cost Every Year?
F: How Many Kinds of Green Energy We Can Take Use of?答案：F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20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 -
