细节理解题的解题步骤和方法
his new idea is not only in the battery’s size, but also in its semiconductor(半导体). kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“the key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶格结构) of the solid semiconductor, ” kwon said. “by using a liquid semiconductor, we believe we can minimize that problem.”
together with j. david robertson, chemistry professor and associate director of the mu research reactor, kwon is working to build and test the battery. in the future, they hope to increase the battery’s power, shrink its size and try with various other materials. kwon said that the battery could be thinner than the thickness of human hair.
74. according to jae kwon, his nuclear battery .
a. uses a solid semiconductor
b. will soon replace the present ones
c. could be extremely thin
d. has passed the final test
这也是一个离散型细节理解题，需要我们在做题时先浏览一下选项对选项中的关键词有所印象，然后在回到原文中寻找对应部位。在本题里a选项说kwon的电池用的是固态半导体，而根据定位词找到的倒数第三段最后一句显示他的电池用的是更为先进的液态半导体，所以a选项是与原文事实相反的；d选项说电池已经通过了最后的测试，而最后一段第二句谈到测试时说道kwon正在努力制造和测试电池，所以d选项把未然变成了已然，应该排除。b选项是对原文的过度猜测，无法推测出这种原子电池能够迅速地替代现在的电池。因此本题的正确答案应该选c选项，在最后两句中我们了解到这种电池可能变得很轻薄。
四、总结
总而言之，要做好占高考英语阅读理解大部分题量的细节题，我们需要用好顺序原则、定位词、排除法这三大法宝。在做题时，按照题号顺序在相应的区域寻找答案。先看题干，标出题干中的定位词，然后根据找到的定位词回到原文寻找定位词在文章中的出处。在遇到模棱两可，难以作出选择的答案是，不妨采用排除法。这就要求我们对正确选项的特点干扰项的特点都有一个较全面的了解。只要同学们用好了这三大法宝，在考试中集中注意力，仔细审题，我相信在解答细节理解题时一定会有游刃有余，得心应手的感觉。
