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）.

Batteries Built by Viruses
What do chicken pox,the common cold,the flu,and AIDS have in common?They're all diseases caused by viruses,tiny microorganisms that can pass from person to person. It's no wonder that when most people think about viruses,finding ways to steer clear of viruses is what's on people's minds.
Not everyone runs from the tiny disease carriers,though. In Cambridge,Massachu- setts,scientists have discovered that some viruses can be helpful in an unusual way. They are putting viruses to work,teaching them to build some of the world's smallest rechargeable batteries.
Viruses and batteries may seem like an unusual pair,but they're not so strange for engi-neer Angela Beicher,who first came up with the idea. At the Massachusetts Institute of
Technology(MIT)in Cambridge,she and her collaborators bring together different areas of science in new ways.In the case of the virus-built batteries,the scientists combine what they know about biology,technology and production techniques.
Beicher's team includes Paula Hammond,who helps put together the tiny batteries,and
Yet-Ming Chiang,an expert on how to store energy in the form of a battery.“We're working on things we traditionally don't associate with nature，”says Hammond.
Many batteries are already pretty small. You can hold A,C and D batteries in your hand. The coin-like batteries that power watches are often smaller than a penny. However, every year,new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink,ordinary batteries won't be small enough to fit in-side.
The ideal battery will store a lot of energy in a small package. Right now,Belcher's model battery,a metallic disk completely built by viruses,looks like a regular watch battery. But inside,its components are very small一so tiny you can only see them with a powerful microscope.
How small are these battery parts?To get some idea of the size,pluck one hair from your head. Place your hair on a piece of white paper and try to see how wide your hair is一 pretty thin,right?Although the width of each person's hair is a bit different,you could probably fit about 10 of these virus-built battery parts,side to side,across one hair. These micro-batteries may change the way we look at viruses.What expression below is opposite in meaning to the word“shrink” appearing in para-graph 5?
A: Broaden.
B: Spread.
C: Extend.
D: Expand.答案：D解析：题干意为“根据第一段的内容来看，人们试图……”。利用题干及备选项中的细节信息词/短语people , microorganisms , chicken pox , flu , various diseases , virus-related diseases , medicines作为定位线索，在第一段中找到相关句：What do chicken pox, the com-mon cold,the flu，and AIDS have in common?They're all diseases caused by viruses（与vi-rus-related diseases呼应）,tiny microorganisms that can pass from person to person. It's no wonder that when most people think about viruses,finding ways to steer clear of viruses is what's on people's minds．第一段第二句提到“这些都是由病毒引起的疾病”，这说明病毒会引起疾病。第三句提到“难怪大部分人一提到病毒，首先想到的是如何躲避病毒”，这说明因为病毒会引起疾病，所以人们都想尽力避开病毒，因此C项“因为病毒会造成各种疾病所以躲避病毒”是答案。虽然选项B也提到了躲避病毒，但是选项B后半句中提到的躲避的原因是因为病毒是看不见的，这在短文中没有提到，因此选项B属于“无中生有”的干扰项。提示：备选项中只要一部分信息在短文中没有被提及，该选项也属于“无中生有”的干扰项；备选项中只要有一部分信息与短文中的相关信息不一致，则该选项陈述的信息与短文信息不一致。

题干意为“下列哪个选项的词义与第五段中shrink的词义相反？”该题属于词汇题。首先找到shrink在短文中所在的语境，并依据该语境判断出shrink的词义是“收缩”，也就是“缩小”，因此它的反义词是expand“增大，扩张”。所以答案为D。

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.Infrared radiation can produce heat______.
A:when it is absorbed by matter
B:when it is cloudy
C:because they can pass through solid objects
D:when the sunrays are fierce.
E:when a change in the nucleus of an atom takes place
F:when electron rearrangement takes place答案：A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。

Batteries Built by Viruses
What do chicken pox,the common cold,the flu,and AIDS have in common?They're all diseases caused by viruses,tiny microorganisms that can pass from person to person. It's no wonder that when most people think about viruses,finding ways to steer clear of viruses is what's on people's minds.
Not everyone runs from the tiny disease carriers,though. In Cambridge,Massachu- setts,scientists have discovered that some viruses can be helpful in an unusual way. They are putting viruses to work,teaching them to build some of the world's smallest rechargeable batteries.
Viruses and batteries may seem like an unusual pair,but they're not so strange for engi-neer Angela Beicher,who first came up with the idea. At the Massachusetts Institute of
Technology(MIT)in Cambridge,she and her collaborators bring together different areas of science in new ways.In the case of the virus-built batteries,the scientists combine what they know about biology,technology and production techniques.
Beicher's team includes Paula Hammond,who helps put together the tiny batteries,and
Yet-Ming Chiang,an expert on how to store energy in the form of a battery.“We're working on things we traditionally don't associate with nature，”says Hammond.
Many batteries are already pretty small. You can hold A,C and D batteries in your hand. The coin-like batteries that power watches are often smaller than a penny. However, every year,new electronic devices like personal music players or cell phones get smaller than the year before. As these devices shrink,ordinary batteries won't be small enough to fit in-side.
The ideal battery will store a lot of energy in a small package. Right now,Belcher's model battery,a metallic disk completely built by viruses,looks like a regular watch battery. But inside,its components are very small一so tiny you can only see them with a powerful microscope.
How small are these battery parts?To get some idea of the size,pluck one hair from your head. Place your hair on a piece of white paper and try to see how wide your hair is一 pretty thin,right?Although the width of each person's hair is a bit different,you could probably fit about 10 of these virus-built battery parts,side to side,across one hair. These micro-batteries may change the way we look at viruses.Which of the following is true of Belcher's battery mentioned in paragraph 6?
A: It is made of metal.
B: It is a kind of watch battery.
C: It can only be seen with a microscope.
D: It is a metallic disk with viruses inside it.答案：D解析：题干意为“根据第一段的内容来看，人们试图……”。利用题干及备选项中的细节信息词/短语people , microorganisms , chicken pox , flu , various diseases , virus-related diseases , medicines作为定位线索，在第一段中找到相关句：What do chicken pox, the com-mon cold,the flu，and AIDS have in common?They're all diseases caused by viruses（与vi-rus-related diseases呼应）,tiny microorganisms that can pass from person to person. It's no wonder that when most people think about viruses,finding ways to steer clear of viruses is what's on people's minds．第一段第二句提到“这些都是由病毒引起的疾病”，这说明病毒会引起疾病。第三句提到“难怪大部分人一提到病毒，首先想到的是如何躲避病毒”，这说明因为病毒会引起疾病，所以人们都想尽力避开病毒，因此C项“因为病毒会造成各种疾病所以躲避病毒”是答案。虽然选项B也提到了躲避病毒，但是选项B后半句中提到的躲避的原因是因为病毒是看不见的，这在短文中没有提到，因此选项B属于“无中生有”的干扰项。提示：备选项中只要一部分信息在短文中没有被提及，该选项也属于“无中生有”的干扰项；备选项中只要有一部分信息与短文中的相关信息不一致，则该选项陈述的信息与短文信息不一致。

题干意为“下列哪个选项的词义与第五段中shrink的词义相反？”该题属于词汇题。首先找到shrink在短文中所在的语境，并依据该语境判断出shrink的词义是“收缩”，也就是“缩小”，因此它的反义词是expand“增大，扩张”。所以答案为D。
题干意为“第六段中关于Belcher所研制的电池的陈述哪个正确？”利用题干及选项中的细节信息词/短语Belcher's battery, metal, watch battery, microscope, metallic disk作为定位线索，在第六段中找到相关句：The ideal battery will store a lot of energy in a small package. Right now，Belcher's model battery,a metallic disk completely built by viru-ses,looks like a regular watch battery. But inside,its components are very small一so tiny you can only see them with a powerful microscope．定位线索词集中出现在第六段第二句中，该句意为“Belcher的电池模型是完全由病毒构成的金属圆盘，看起来就像普通的手表电池”。显然，B项“它是一种手表电池”与短文意思不一致：短文中出现的手表电池是用作比较，而不是说Belcher 的电池模型是手表电池。该句意思与D项“它是一种金属圆盘，里面有病毒”一致，因此D是答案。C项“它只能在显微镜下才能看见”，这与第六段最后一句意思不一致：第六段最后一句提到“电池里面的部件很小―小到用高倍显微镜才能看到”，这是在讲述电池部件的情况，并非说电池也需要用显微镜才能看见，因此选项D陈述的信息与短文内容不一致。 -
