19.Iceland has energy to spare,and the small country has found a cutting-edge (尖端的) way to reduce its oil dependency.Volcanoes formed the island nation out of ash and lava,which heats huge underground lakes to the boiling point.The hot water is piped into cities providing heat for homes,businesses and even swimming pools.The volcanoes melted ice,which formed rivers.The water runs through turbines,providing all the country's electricity.Iceland wants to make plans to improve its cars,buses and trucks to run n renewable energy.Iceland has already started by turning water into fuel-hydrogen fuel.Here's how it works:Electrodes (电极) change the water into hydrogen and oxygen molecules.Hydrogen electrons pass through a conductor that creates the current to power an electric engine.
Hydrogen fuel now costs two to three times as much as gasoline,but gets up to three times the distance than gas,making the overall cost about the same.As an adde benefit,there is no carbon-only water steam.
In the capital,Reykjavik,they are already testing three hydrogen-powered electric buses.The drivers are impressed."I like these buses better because with hydrogen you get no pollution,"said bus driver Rognvaldur Jonatanlson.By the middle of this century,all Icelanders will be required to run their cars only on hydrogen fuel,meaning no more gasoline.
"If we make hydrogen and use that as a fuel for transportation then we can run the whole society on our own local renewable energy sources,"said Marie Mack.Icelanders are showing the orld that by making fuel from water,it is possible to kick the oil habit.
32.From Paragraph 1we may infer thatD.
A.Iceland lacks natural resources
B.all the country's electricity is made from coal
C.Iceland mainly depends on oil for energy
D.volcanoes do more good than harm to Iceland
33.Which of the following is necessary during the period of turning water into fuel according to Paragraph 2?A
A.Conductor.
B.Electric engine.
C.Electricity.
D.Turbine.
34.The advantage for the cars with hydrogen as fuel is thatC.
A.the cars run much faster.
B.the cars are cheap.
C.the cars are environmentally friendly.
D.the cars will make useful steam.
35.What would be the best title for the passage?B
A.Pollution saying Good-Bye to the world.
B.Iceland planning to use water as fuel.
C.Iceland becoming a country without oil.
D.Man able to kick the oil habit.
分析 本文主要介绍冰岛充分利用本国的自然资源,研究利用水来充当燃料能源.
解答 DACB
32 D 细节题. 根据文章的第一段Volcanoes formed the island nation out of ash and lava,which heats huge underground lakes to the boiling point.可知,在冰岛,火山提供很多地热资源,火山融水可用来发电,可推断冰岛的火山利大于弊,故选D.
33 A 细节题. 根据文章第二段的Hydrogen electrons pass through a conductor that creates the current to power an electric engine.氢电子必须通过可以给电子引擎提供动力的导体,因此导体是中介,故选A.
34 C 细节题. 根据文章的第三段和第四段with hydrogen you get no pollution,"可知,这种汽车对环境不造成污染.故选C
35 B 主旨大意题.本文主要介绍冰岛充分利用本国的自然资源,在研究利用水来充当燃料能源.故选B.
点评 做阅读理解时要快速的浏览全文,把握文章主旨大意,带着问题回到原文,寻找细节或概括相应的答案,最后要理清作者写作思路.
