2017年翻译资格考试catti三级笔译实务练习题（1）

　　【英译汉】

　　If you have never seen a power plant,you might find it hard to imagine how enormously complex the equipment is or how much heat is generated by the boilers or how much coal it takes to fuel the furnaces for just one day.

　　During the course of a day,the boilers at one of our power plants,Morgantown,for example,can turn 24 million gallons of water into steam.That generating plant alone uses 9,900 tons of coal in its furnaces in just one day.Potomac Electric Power Company(PEPCO)uses so much coal that we have purchased two 80-car unit trains to facilitate the delivery process.And Morgantown alone can produce over 25 million kilowatthours of electricity in a single day’s operation.

　　Electricity is produced by spinning large magnets inside a coil of wire within the generator.The faster we spin the mangnets,the higher will be the voltage of the electricity produced.Electricity leaves a PEPCO generator at between 13,800 and 24,000 volts.

　　The next step in the process occurs when electricity passes through a transformer where the voltage is stepped up to continue on its journey.A transmission wire is like a small diameter pipe.Stepping up the voltage is like increasing water pressure,thus speeding the flow of energy through the system.

　　【参考译文】

　　如果你从未见过一座发电厂，你可能很难想象发电设备是多么复杂，锅炉能产生多么巨大的热量，而炉子每天又是需要烧多少煤。

　　举例说，我们的一座发电厂——摩根顿发电厂——的各台锅炉一天中就能把二千四百万加仑的水化为蒸汽。这座电厂的炉子一天之内就消耗九千九百吨煤。波多马克电力公司(PEPCO)用煤量如此巨大，以致我们专门购置了两列八十节车皮的火车以加速输送煤的过程。仅仅一座摩根顿电厂就能每天生产二千五百万千瓦小时的电。

　　电是靠使大型磁铁在发电机内的线圈里面转动而产生的。磁铁转速愈高，产生的电压就愈高。电流从波多马克电力公司的发电机出来时，其电压在13,800伏至24,000伏之间。

　　下一道程序是使电流通过一个变压器，把电压提升，并使电继续向前进。一根导线就象一根小口径的水管。把电压升高就象给水加压一样，这样一来就会使这个系统中能量的运动加快。
