2016年職稱英語(yǔ)考試真題理工類A級(jí)概括大意
第3部分：概括大意與完成句子(第23——30題，每題1分，共8分)
Geothermal(地?zé)?Energy
1 Since heat naturally moves from hotter regions tocooler ones， the heat from the earth's center flows outwards towardsthe surface。 In this way， it transfers to the next layer of rock。 If the temperatureis high enough， some of this rock melts and forms magma(巖漿)。 The magmaascends in its turn towards the earth's surface。 It often remains well below the earth's surface， creating vast areasof hot rock。 In such regions， there are deep cracks， which allow rainwater to descend underground。 Some of the heatedrainwater travels back up to the earth's surface where it will appear as a hotspring。 However， if this ascendinghot water reaches a layer of impermeable(不可滲透的)rock， it remains trapped， forming a geothermal reservoir。 If geothermalreservoirs are close enough to the surface， they can be reached by drilling wells。 Hot water and steamshoot up the wells naturally， and can be used to produce electricity in geothermalpower plants。
2。A few geothermal power plants depend on dry-stemreservoirs which produce steam but little or no water。 In these cases， the steam is pipedup directly to provide the power to spin a turbine generator。 The first geothermalpower plant， constructed at Lardarello in Italy， was of this type， and is stillproducing electricity today。
3。Most currently operating geothermal power plants areeither "flash" steam plants or binary(雙重的)plants。 Flash plants produce mainly hot water ranging intemperature from 300° to 700°Fahrenheit。 This water is passed through one or two separators wherereleased from the pressure of the underground reservoir， it"flashes" or boils into steam Again， the force of this steam provides the energy to spin theturbine and produce electricity。 The geothermal water and steam are then reinjecteddirectly back down into the earth to maintain the volume and pressure of thereservoir。 Gradually they will be reheated and can then be usedagain。
4。A reservoir with temperatures below 300° Fahrenheit is nothot enough to flash steam but it can still be used to generate electricity inbinary fluid。 The steam from this is used to power the turbines。 As in the flashsteam plant， the geothermal water is recycled back into the reservoir。
