英语翻译
The modern age in an age of electricity.people are so used to electric lights,radios,televisions,and telephones that it is hard power 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 sent out tiny pulses of electricity.As the heart beats,it sends out pulses that can be measured and recorded on the surface of the body.When the pulses are recorded,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 cna 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 effect can be astonishing.
The electric eel is an amazing living 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 this body.

现代是一个电的时代.人们已经很习惯了电灯\收音机\电视和电话,难以想象如果没有炉这些生活会是什么样子.当停电的时候,人们在摇曳的烛光中摸索着,街上的汽车也因为没有交通指示灯而停滞不前,食物静静地在冰箱里变坏.
然而人类认识电只是两个多世纪的事情.大自然却已经在电这块领域试验了几亿年了.科学家们正在发掘更多可以使人类受益的电的奥秘.
所有的活细胞都在发送微弱的电脉冲.当心脏在跳动的时候,脉搏可以在身体表面测到并且被记录.脉搏一旦被记录在心电图中,医生就可以依据它看出心脏是否正常运作.大脑也是,发送出可以记录在脑电图中的脑电波.大多数活细胞产生的电流是极小的---经常是小到需要用很精密的仪器去记录它们.但是有一些动物,它们的部分肌肉细胞已经作为发电机,分化得太厉害了以至于完全不像一般的肌肉细胞那样运作了.当大量的这种细胞被连接在一起,产生的效果是令人惊讶的.
电鳗是一种不可思议的活电池.它能在它的水域周围发出一个八百伏特的大电波.(一个electric house电房?目前只有一百二十伏) 电鳗的身体中有五分之四的细胞都被分化成了发电机,而这强大的电流它可以通过它长长的身体很快的传递出去.
