1、专题限时训练(二十二)科普知识型阅读理解(一)(限时：25分钟)AThe forces that make Japan one of the worlds most earthquakeprone(有地震倾向的) countries could become part of its longterm energy solution.Water from deep below the ground at Japans tens of thousands of hot springs could be used to produce electricity.Although Japanese hi
2、ghtech companies are leaders in geothermal(地热的) technology and export it, its use is limited in the nation.“Japan should no doubt make use of its resources of geothermal energy，” said Yoshiyasu Takefuji, a leading researcher of thermalelectric power production.The disastrous earthquake and tsunami o
3、n March 11, 2011 caused a reaction against atomic power, which previously made up 30 per cent of Japans energy needs, and increased interest in alternative energies, which account for only 8 per cent.Artist Yoko Ono has called on Japan to explore its natural energy, following the example of Iceland
4、which uses renewable energy for more than 80 per cent of its needs.For now, geothermal energy makes up less than 1 per cent of the energy needs in Japan, which has for decades relied heavily on fossil fuels and atomic power.The biggest problem to geothermal energy is the high initial cost of the exp
5、loration and constructing the factories.Another problem is that Japans potentially best sites are already being developed for tourism or are located within national parks where construction is forbidden.“We cant even dig 10cm inside national parks，” said Shigeto Yamada of Fuji Electric, adding that
6、regulations protecting nature would need to be relaxed for geothermal energy to grow.Researcher Hideaki Matsui said, “Producing electricity using hot springs is a decadeslong project.We also have to think about what to do for now as energy supplies will decline in the short term.”The Earth Policy In
7、stitute in Washington, the US, believed Japan could produce 80，000 megawatts(兆瓦)and meet more than half its electricity needs with geothermal technology.Japanese giants such as Toshiba are already global leaders in geothermal technology, with a 70 per cent market share.In 2010, Fuji Electric built t

11、ly handicapped. Not only is it unable to see, but because it cannot receive the visual stimulus(刺激)from its environment that a sighted child does, it is likely to be slow in intellectual development. Now the tenmonthold son of Dr and Mrs Dennis Daughters is the subject of an unusual psychological ex

With the aid of a sonartype electronic that he wears on his head, infant(婴儿) Dennis is learning to identify the people and objects in the world around him by means of echoes(回声)The device is an improvement of the “Sonicguide”， an instrum
13、ent produced by Telesensory Systems, Inc., of Palo Alto, Calif, and used by blind adults in addition to a sane or guide dog. As adapted for Dennis, it consists of a batterypowered system about the size of a half dollar that is on a headgear. A transmitter sends out an ultrasonic(超声的) pulse that crea

Echoes from objects within the cone are perceived (felt) as sounds that vary in pitch(音调) and volume(音量) with the size and distance of the object.The closer an object is, the lower the pitch, and the larger the object, the louder the signal. Hard surfaces pr

Thus, by simply moving his head right and left and up and down, he can not only locate an object but also get so

By turning his head away, he makes her seem to disappear. “From the first time he wore it，” says Mrs Daughters, “it was like a light going on in his head.”What remains to be determined is how well the device will help Dennis cope with his surroundings as he begins to walk and venture further int

She beat out more than 1，600 finalists from 70 countries. She said that she has been c

28、 passage starts with _Awhat problem most teenagers meet with in lifeBhow Khare helped others with their problems专题限时训练(二十二)A【要点综述】 文章主要讲述了日本正在考虑开发地热能这样一件事，因为日本是地震多发国家，国家地热能非常丰富，所以地热能将是日本的新型替代能源。1D文章主要讲述了日本正在考虑开发地热能，所以是围绕地热能的话题展开。故选D项。2B从第六段“For now, geothermal energy makes up less than 1 per cent of
29、 the energy needs in Japan, which has for decades relied heavily on fossil fuels and atomic power.”可知，日本地热能不到1%，主要依赖于化石燃料和原子能。故选B项。3A从倒数第四段“adding that regulations protecting nature would need to be relaxed for geothermal energy to grow.”可知，要开发地热能，需要将现行的规章制度进行改变，故选A项。4B从“Producing electricity using
30、hot springs is a decadeslong project.”可知，Hideaki Matsui 认为地热能是个长期的项目，故选B项。5C从最后两段“believed Japan could produce 80，000 megawatts(兆瓦)and meet more than half its electricity needs with geothermal technology”可知，日本在地热能方面有着巨大的潜力，故选C项。B【要点综述】 本文主要介绍了一项针对盲童的学习过程的研究。1B首段第三句末的不定式“to prevent a lag(滞后) in the l
31、earning process”表明了Daughters夫妇研究的目的。另外，文章一开头就提到了本文讨论的重点是针对blind baby的，由此可见，选项B为本题答案。2C首段首句提到的a blind baby，第三句提到的tenmonthold和末句提到的infant等词都表明Dennis成为研究对象是因为Daughters夫妇研究的是盲童从小的学习过程，Dennis年龄很小，正处于学习的最初阶段，符合Daughters夫妇做研究的条件，因此选项C为本题答案。3A第二段首句中的improvement表明Dennis用的声呐定位仪是“Sonicguide”的改良版，也就是说“Sonicguid
32、e”是Dennis的声呐定位仪的原型。根据该句对其功能的描述可以确定选项A为本题答案。4A第三段第四句中的thanks to 表明此处解释了Dennis的声呐定位仪的运作机制，即通过声波描绘物体的形状，该句中the cone指的就是该定位仪，而its edge应指周围物体的边缘。当声波碰到物体的边缘时，就能通过声音描绘出物体的形状了，因此本题答案应为A。5D从末段末句中的schoolage children及句中的其他内容可以推断Telesensory 最可能认为Dennis的声呐定位仪有利于儿童的学习过程，因此选项D为本题答案。C【要点综述】 一位高中生因其一项发明而在英特尔国际科学与工程大
33、赛中胜出，并因此获得50，000美元的奖金。该发明虽然看起来很小，但却能储存大量的能量，因此可以迅速给手机充电。1C根据第二段“Im a teenager and I have a cellphone and my cellphone battery always dies, so I was really looking for a way to improve energy storage”可知全文首先介绍Khare发明该事物的起因，故选C项。2AKhare今年18岁，再根据第三段“The teenager from California, who graduated from high
34、school last week, won a $50，000 prize on May 17, 2013 at the Intel International Science and Engineering Fair”可知该文写于2013年，由此可推断她应该出生于1995年。3D根据第五段“The technology isnt available to consumers yet, and it could be years until it is.”可知该发明尚未投入使用，故选D项。4C根据第五段“Khare hasnt used her invention to recharge a cellphone yet, but she used it to power a lightemitting diode (LED) in order to show its capability(容量)”可判断选C项。5B根据最后两段可知Khare当前的计划是要进入哈佛大学读书，故选B项。
