Electricity is the science, engineering, technology and physical phenomena associated with the presence and flow of electric charges. Electricity gives a wide variety of well-known electrical effects, such as lightning, static electricity, electromagnetic induction and the flow of electrical current in an electrical wire. In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves.Electrical phenomena have been studied since antiquity, though advances in the science were not made until the seventeenth and eighteenth centuries. Practical applications for electricity however remained few, and it would not be until the late nineteenth century that engineers were able to put it to industrial and residential use. The rapid expansion in electrical technology at this time transformed industry and society. Electricity's extraordinary versatility as a means of providing energy means it can be put to an almost limitless set of applications which include transport, heating, lighting, communications, and computation. Electrical power is the backbone of modern industrial society, and is expected to remain so for the foreseeable future.[ 初一水平太难了吧,几乎都没多大词汇……

The other voice that whispers reassurances that everything is fundamentally okay simply delivers its message with quiet confidence. Once we hear it, we know it speaks the truth. Generally, once we have heard what it has to say, a powerful sense of calm settles over our entire being, and the other voices and sounds, once so dominant, fade into the background, suddenly seeming small and far away. We may find that our own communications in the world begin to be influenced by the quiet certainty of this voice. We may be less inclined to indulge in idle chatter as we become more interested in maintaining.

Saving ElectricityWe use electricity nearly everwhere in our daily life, so it's very important for us to save electricity. There are many ways of saving electricity. Here are some ways we can do easily around us.Use less electricity as often as possible. Keep only one light on when we watch TV. Turn off the light if there is enough light in the room. Don't let the light on when we leave the room. In summer, we can open the doors and windows to let the room cool, and try not to turn on the air conditions if it's not neccessary.Try to use the energy-saving instruments. For example, we can use the energy-saving bulb instead of normal lights. We can also use LED TV sets or monitors instead of CRT or LCD ones.If everyone can pay attention to saving electricity, that will be a good deed for the next generation.

ElectricityThe modern age is an age of electricity.People are so used to electric lights,radio,televisions,and telephones that it is hard to imagine what life would be like without them.When there is a power failure,people grope about in flickering candlelight,cars hesitate in the streets because there are no traffic lights to guide them,and food spoils in silent refrigerators.Yet,people began to understand how electricity works only a little more than two centuries ago.Nature has apparently been experimenting in this field for millions of years.Scientists are discovering more and more that the living world may hold many interesting secrets of electricity that could benefit humanity.All living cells send out tiny pulses of electricity.As the heart beats,it sends out pulses of record; they form an electrocardiogram,which a doctor can study to determine how well the heart is working.The brain,too,sends out brain waves of electricity,which can be recorded in an electroencephalogram.The electric currents generated by most living cells are extremely small -- often so small that sensitive instruments are needed to record them.But in some animals,certain muscle cells have become so specialized as electrical generators that they do not work as muscle cells at all.When large numbers of these cells are linked together,the effects can be astonishing.The electric eel is an amazing storage battery.It can send a jolt of as much as eight hundred volts of electricity through the water in which it lives.(An electric house current is only one hundred twenty volts.) As many as four-fifths of all the cells in the electric eel's body are specialized for generating electricity,and the strength of the shock it can deliver corresponds roughly to the length of its body.电当今时代是电气时代.人们对电灯、收音机、电视和电话早已司空见惯以致很难想象没有它们生活会变成什么样.当停电时,人们在摇曳不定的烛光下暗中摸索;因没有红绿灯的指示,汽车在道路上迟疑不前;冰箱也停止工作,导致食物变质.人们只是在两个世纪前一点才开始了解电的使用原理,自然界却显然在这方面经历过了数百万年.科学家不断发现许多生物世界里可能有益于人类的关于电的有趣秘密.所有生物细胞都会发出微小的电脉冲.当心脏跳动时,把它发出的脉冲记录下来就成了心电图,这可让医生了解心脏的工作状况.大脑也发出脑电波,这可在脑电图上记录下来.许多生物细胞发出的电流都是极微小的,小到要用灵敏仪器才能记录和测量.但一些动物的某些肌肉细胞能转化成一个个发电机,以致完全失去肌肉细胞的功能.这种细胞大量地连接在一起时产生的效果将是非常令人吃惊的.电鳗就是一种令人惊异的蓄电池.它可以在水中发出相当于800伏特电压电流(家庭用户的电压只有120伏特).在电鳗的身体里,多至五分之四的细胞都专门用来发电,而且发出的电流的强度大约和它身体的长度成正比
