1、阅读强化训练(十二)(建议用时：25分钟) 阅读理解The discussion on renewable energy has been going on for at least a decade and people have relied on fossil fuels almost entirely for more than a century.However，the situation when fossil fuels were the most efficient and the cheapest source of energy has been left far in t
2、he past.Many countries such as Germany and Sweden have already made significant efforts to fix this situation，employing numerous power plants working on the renewable resources of energy.The most effective among these resources is geothermal(地热的) energy.Geothermal energy does not depend on the world
3、s economic and political situation as strongly as fossil fuels do. Besides, extracting(提炼) fossil fuels adds up to the price of energy produced from them.Therefore，geothermal energy is much cheaper than traditional ones，saving up to 80% of the costs over fossil fuels.Being a renewable resource，geoth
4、ermal energy produces less waste and pollution than traditional energy sources.In geothermal systems，carbon dioxide makes up about 10% of air produced.Overall，in order to produce the electricity that can be used for one hour，the geothermal systems produce 0.1 pound of carbon dioxide and other harmfu
5、l gases.For a comparison，a power plant producing electricity from gas produces up to 2 pounds of carbon dioxide into the atmosphere，and those power plants that work on coal(煤) produce an astonishing 3.6 pounds of greenhouse gases.Low costs make another reason why using geothermal power plants should
6、 be the first choice for many countries.Geothermal heat systems require 25% to 50% less energy for work compared with the traditional systems for heating or cooling.Besides，geothermal equipment is less bulky：due to the very nature of geothermal energy，geothermal power plants have only a few moving p
7、arts，all of which can be easily sheltered inside a relatively small building.Whats more，the life span of geothermal equipment is rather long.All these make geothermal power stations easy to build and keep.【解题导语】地热作为非常重要的可再生清洁能源，将会给人们带来巨大的好处。1Fossil fuels are more expensive than geothermal energy par
8、tly because_Afossil fuels are nearly used upBit is free to use geothermal energyCthe production of fossil fuels costs a lotDgeothermal energy doesnt depend on political situationC解析：细节理解题。根据第二段第二句Besides，extracting(提炼) fossil fuels adds up to the price of energy produced from them.可知，化石燃料需要经过提炼才能生产出

10、，经过对比发现，用地热能源生产电比用汽油和煤炭生产电更环保，因为用地热能源生产电排放的温室气体较少，故答案为B项。3What does the underlined word“bulky”in the last paragraph mean?ABeing really big and heavy.BBeing convenient to operate.CBeing expensive and low effective.DBeing unfriendly to the environment.A解析：词意猜测题。根据最后一段第三句中的due to the very nature of geo
11、thermal energy，geothermal power plants have only a few moving parts，all of which can be easily sheltered inside a relatively small building可知生产地热的设备不是那么大而笨重的，因为它只有一些运转部件并能够放在相对小的建筑中，故答案为A项。4What is the main idea of this passage?AFossil fuels are being run out of.BGeothermal energy is well accepted.C
12、Geothermal energy has many advantages.DMany countries have benefited from geothermal energy.C解析：主旨大意题。作者主要通过价格、环保、运行成本这三方面证明了地热能源比传统能源更有优势，故答案为C项。 完形填空The summer heat made me really uncomfortable.I stayed inside，feeling 1 ，lonely，and depressed.I walked out and entered an Indoor Flea Market.Id never
