[答案与考点解析] 1.【答案】<span word="C">C</span> 【考点解析】本题是一道中心主旨题。本文的中心主旨句是首段的第二句，该句中的<span word="these">these</span> <span word="materials">materials</span>指的就是首段第一句中的<span word="amorphous">amorphous</span> <span word="metallic">metallic</span> <span word="alloys">alloys</span> <span word="or">or</span> <span word="glassy">glassy</span> <span word="metals">metals</span>。可见本题的正确答案应该是<span word="C">C</span>。考生一定要知道：破解中心主旨题的关键在于抓住全文的中心主旨句。 2.【答案】<span word="C">C</span> 【考点解析】本题是一道审题定位题。根据题干中的<span word="prospects">prospects</span>可将本题的答案信息迅速确定在尾段，因为尾段首句中的<span word="promising">promising</span>（有前途的）暗示本段讲某种事物的前景或未来。本题的确切答案信息来源在尾段的最后一句，该句中的<span word="that">that</span> <span word="is">is</span> <span word="likely">likely</span> <span word="to">to</span> <span word="be">be</span> <span word="overcome">overcome</span>暗示本题的正确答案是<span word="C">C</span>。考生在解题时一定要具备迅速地审题定位能力，还要具备理解原文深层含义的能力。 3.【答案】<span word="D">D</span> 【考点解析】这是一道细节推导题。根据题干中的<span word="crystalline">crystalline</span> <span word="structure">structure</span>可将本题的答案迅速确定在第二段的首句，该句中的<span word="depends">depends</span> <span word="on">on</span>和题干中的<span word="determines">determines</span>相互呼应。通过仔细理解第二段的首句可推导出本题的正确选项是<span word="D">D</span>。请考生注意原文中<span word="composition">composition</span>和选项中<span word="consists">consists</span> <span word="of">of</span>的转换。考生在解题时一定要具备细节推导能力，不能只停留于文字的表面含义。 4.【答案】<span word="D">D</span> 【考点解析】这是一道细节推导题。根据题干中的<span word="the">the</span> <span word="structure">structure</span> <span word="of">of</span> <span word="liquid">liquid</span> <span word="metals">metals</span> <span word="and">and</span> <span word="the">the</span> <span word="structure">structure</span> <span word="of">of</span> <span word="glassy">glassy</span> <span word="metals">metals</span>可将本题的答案信息来源迅速确定在第三段的首句。该句中的<span word="similar">similar</span>一词暗示选项<span word="D">D</span>是正确答案。考生在解题时应重视对立对比关系。 5.【答案】<span word="C">C</span> 【考点解析】本题是一道总结归纳信息并进行引申推导题型。从本题题干中的<span word="molten">molten</span> <span word="nonmetallic">nonmetallic</span> <span word="glasses">glasses</span>可断定本题的答案信息在本文第二段，因为该句中包含有题干中的核心词语<span word="molten">molten</span> <span word="nonmetallic">nonmetallic</span> <span word="glasses">glasses</span>。我们需要归纳和总结本段的每一句话，尤其是第三、四句的内容，另外本段尾句的含义为推导（<span word="infer">infer</span>）出本题的正确选项<span word="C">C</span>起到至关重要的作用。考生在破解此类题型时一定要注意首先归纳和总结原文中相应出题点的全面信息，更要注意逻辑推导的能力。 [参考译文] 材料科学家和固体物理学家的深入研究已促进了一种固体物质的出现，这类固体被称为非晶体金属合金，也就是玻璃金属。理论和应用研究者对这些材料的结构特性的兴趣正与日俱增。 当一种熔化的金属和金属合金冷却成固体时，依赖于特定的合金成份将形成各种晶体结构。相比之下，熔化的非金属、玻璃类材料在冷却后将不会形成晶体结构，而是保留一点类似于液体的非晶体结构，在室温条件下，两类材料的自然的长期倾向都形成了晶体结构。它们之间的不同在于动态性，即形成晶体结构的速度。这种动态性受下述两种因素控制：化学结合的性质和分子之间相互运动的自由程度。由此，对金属而言，动态历程有利于晶体结构的快速形成；而对非金属来说，这种形成速度非常慢，以至于任何自然冷却速度都足以形成一种非晶体结构。要想形成玻璃金属，熔化的金属必须以极快的速度冷却，以抑制晶体的形成。 人们认为玻璃金属的结构与液态金属的结构类似。创建这种液体结构模型的第一次尝试是已故的伦敦大学的<span word="J">J</span>. <span word="D">D</span>.鲍纳尔进行的，他将坚硬的球体尽可能多地填塞进一个橡胶容器中，以便得到一种最大可能的密度。这个密度结果以及随机填塞结构以后便成为试图建立玻璃金属结构模型的基础。 基于鲍纳尔模型，由合成金属的成份组成对合金密度的计算结果与实验测得的结果相当地吻合，当然一些细微的差异仍然存在。实验结果是通过测量由一种重金属和类金属组成的合金得到的，如钯和硅的合金，或铁磷和碳组成的合金。实际的合金和鲍纳尔模型所用的球体之间的差别在于合金的成份有不同的体积大小，因此，基于两种大小的球体的模型更适合于两类物质的合金。合金中非金属的小原子可能填进由大原子随机填塞形成的紧密结构中。 玻璃金属最有前景的一个特征是高强度与高延伸性的结合。在常见的晶体材料中，这两种特性一般是成反比的，但人们渴望它们同时存在。在实际用途中可能还有一个问题急待解决，即当玻璃金属在相对的低温下慢慢加热时，它会逐渐变为晶体结构。</p>
