西安电子科技大学考博英语模拟真题及其解析One of the simplest and best known kinds of crystal is the ionic
salt,of which a typical example is sodium chloride,or ordinary table
salt.The fundamental components of an ionic salt are ions:atoms or
molecules that have become electrically charged by gaining or losing
one more electrons.In forming sodium chloride,for example,sodium
atoms give up an electron(thereby becoming positively charged)and
chlorine atoms gain an electron(thereby becoming negatively charged).
The ions are attracted to one another by their opposite charges,and
they stack together compactly,like tightly packed spheres.
Recently,scientists at Michigan State University created a new
kind of crystal called an electride.In electrides,the anions Geng

xi quan guo mian fei zi xun dian hua:si ling ling liu liu ba liu jiu
qi ba,huo jia zi xun qq:qi qi er liu qi ba wu san qi(negative ions)
are completely replaced by electrons,which are trapped in naturally
formed cavities within a framework of regularly stacked cations
(positive ions).Electrides are the first examples of ionic salts in
which all these anionic sites are occupied solely by electrons.
Unlike other types of anions,anionic electrons do not behave as
if they were simple charged spheres.In particular,because of their
low mass and their tendency to interact with one another over great
distances,they cannot be“pinned down”to any one location.Instead,
they wander close to and among the atoms lining the cavity and interact
with electrons in nearby cavities,perhaps changing places with them.
The properties of an electride depend largely on the distance between the cavities that hold trapped electrons.When the trapped electrons are far apart,they do not interact strongly,and so behave somewhat like an array of isolated negative charges.When they are closer together,they begin to display properties associated with large ensembles of identical particles.When they are still closer, the ensemble properties dominate and the electrons“delocalize”: they are no longer tightly bound within individual cavities but are more or less free to pass through the spaces within the framework of positive ions.
By synthesizing electrides from a variety of materials,one can vary the geometry of the anionic cavities and their relation to the surrounding cations.The resulting properties may make it possible for electrides to become a basis for economically useful new materials and devices.For instance,because the electrons in some electrides are very weakly bound,these crystals could be effective as photosensitive detectors,in which an impinging photon liberates an electron,resulting in a small electric current.The same weak binding could also make electrides useful in solar energy converters and as cathodes in batteries.One obstacle is the tendency of electrides to decompose through reaction with air and water.Researchers are seeking ways to increase their stability.

[答案与考点解析]
1.【答案】B
【考点解析】本题是一道中心主旨题。本文的中心主旨句在第二段的第一句，如果抓住了这句话并且联系每段的中心主旨句，就可得出本题的正确选项B。其实本文第二段就是在讲一种新的晶体的与众不同的“characteristics”(特点)。考生在解题时一定要首先找出全文的中心主旨句，并与上下文联系。
2.【答案】D
【考点解析】这是一道段落关系题。从第二段到尾段是本文作者阐述其中心思想的段落。在展开中心思想之前，作者为中心思想的展开进行了铺垫(讲述一般晶体的特点)，从而为第二段到尾段的陈述(讲述一种新晶体的特点)提供明确的对比。考生在解题时一定要注意段落之间的关系。
3.【答案】D
【考点解析】这是一道审题定位题。题干中没有给出明确的审题定位信息。破解此题需要考生平时的阅读积累，这是一道较难的题目。题干中所涉及的是“the defining characteristic of an electride”(电子晶体的特点)。在第二段作者第一次在文章中谈到了“electride”，所以其特点也应该在第二段向读者交待，故本题的答案信息来源应该在第二段。综合第二段第二、三句的内容可推导出本题的正确选项D。考生在解题时一定要具备出色的审题定位能力。
4.【答案】D
【考点解析】本题是一道句间关系与反推题。题干中的信息以将本题的答案信息确定在第三段。根据第三段所陈述的内容进行反推可得出本题的正确选项D。在进行反推时一定要注意第一句中的“do not behave as if…”以及第二句中的“cannot be pinned down”所起的作用。考生在解题时一定要具备反推即逆向推理的能力。
5.【答案】B
【考点解析】这是一道审题定位题。本题的题干没有提供任何审题定位的信息。但是善于阅读的考生应该知道每篇文章尾段的重要性。在本题到来之前本文的尾段还没有涉及任何一道题，故考生应该首先从尾段中寻找本题的答案信息。尾段的第二句第四句表明新的晶体在商业方面的可利用性;尾段的第五句表明这种新的晶体的不足之处。可见本题的正确选项应该是B。考生在解题时一定要对文章结构以及出题点有所认识，最好对全文有整体的把握。
[参考译文]
在各种最简单和最常见的晶体中，离子盐是其中一例，它典型的实例就是氯化钠，或普通的食盐。离子盐的基本组成成份便是离子，也就是那些由于得到或失去一个或多个电子而带有电荷的原子或分子。例如，在形成氯化钠的过程中，钠原子释放一个电子(从而带有正电荷)而氯电子得到一个电子(从而带有负电荷)。这些离子由于带有相反的电荷而相互吸引，它们紧密地堆砌在一起就象紧密挤压在一起的球体。
最近，密西根州立大学的科学家们研制出一种新的被称为电子晶体的晶体。在电子晶体中，阴离子(即带负电荷的离子)全部被电子替代，这些电子被困在自然形成的空穴中，而空穴位于规则堆砌的阳离子(即带正电荷的离
子)的框架内。电子晶体是第一种阴离子空间全被电子占据的离子盐。
和其它类型的阴离子不同，作为阴离子的电子不像那些简单的带电球体。特别地，由于它们的质量很小而且有与远距离的离子进行相互作用的倾向，它们不会被固定在任何一个位置。相反，它们会到处游离，或者紧靠那些在空穴边上的原子，或者在这些原子之间游离，并且还和附近空中的电子发生相互作用，甚至于可能与它们交换位置。
电子晶体的特征很大程度上依赖于空穴间的距离，而这些空穴便是容纳被捕获电子的地方。当这些被捕获的电子相距很远时，它们之间的相互作用不强，因而在某种程度上表现为一组相互孤立的负电荷。但当它们间的距离很近时，它们便表现出一些特征来，很像大量相同离子的集合。当它们间的距离更近时，群体集合属性更占主导地位，而且电子也出现“离位”现象：它们不再被束缚于单个的空穴之上，而是或多或少地可以在正离子的构架之间穿越。
通过从不同的材料来合成电子晶体，科学家们可以改变阴离子空穴的几何结构，以及改变它们同周围阴离子之间的关系。这些随之而来的特征使得电子晶体可能成为经济实用的新材料和新设备的基础。例如，由于在某些电子晶体中，电子结合得非常微弱，从而使得这些晶体可以有效地用作光敏探测器。在这种探测器中，一束光子可以释放一个电子，从而形成一股小电流。这种结合微弱的特性同样可使电子晶体对太阳能转换器和电池的阴极很有用。可电子晶体的一个缺陷在于它易于与空气和水发生反应而分解。目前，研究人员正设法寻找提高电子晶体稳定性的方法。

四川大学2012考博英语真题及答案详解 阅读 1）Sign has become a scientific hot button. Only in the past 20 years have specialists in language study realized that signed languages are unique—a speech of the hand. They offer a new way to probe how the brain generates and understands language, and throw new light on an old scientific controversy: whether language, complete with grammar, is something that we are born With, or whether it is a learned behavior. The current interest in sign language has roots in the pioneering work of one rebel teacher at Gallaudet University in Washington, D. C., the world’s only liberal arts university for deaf people. When Bill Stokoe went to Gallaudet to teach English, the school enrolled him in a course in signing. But Stokoe noticed something odd: among themselves, students signed differently from his classroom teacher. Stokoe had been taught a sort of gestural code, each movement of the hands representing a word in English. At the time, American Sign Language (ASL) was thought to be no more than a form of pidgin English (混杂英语). But Stokoe believed the “hand talk” his students used looked richer. He wondered: Might deaf people actually: have a genuine language? And could that language be unlike any other on Earth? I t was 1955, when even deaf people dismissed their signing a s “substandard”. Stokoe’s idea was academic heresy (异端邪说). It is 37 years later. Stokoe—now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture—is having lunch at a cafe near the Gallaudet campus and explaining how he started a revolution. For decades educators fought his idea that signed languages are natural languages like English, French and Japanese. They assumed language must be based on speech, the modulation (调节) of sound. But sign language is based on the movement of hands, the modulation of space. “What I said,” Stokoe explains, “is that language is not mouth stuff—it’s brain stuff.” 21. The study of sign language is thought to be _____C___. A) a new way to look at the learning of language B) a challenge to tradi t ional, views on the nature of language C) an approach: to simplifying the grammatical structure of a language D) an attempt to clarify misunderstanding about the origin of language（C） 22. The, present growing interest in sign language was stimulated by ___C_____. A) a famous scholar in the study of the human brain B) a leading specialist in the study of liberal arts C) an English teacher in a university for the deaf D) some senior experts in American Sign Language（C） 23. According to Stokoe, sign language is _____B___. A) a Substandard language B) a genuine language C) an artificial language D) an international language（B）

General English Admission Test For Non-English Major Ph.D. program (Harbin Institute of Technology) Passage One Questions 1-7 are based on the following passage: According to a recent theory, Archean-age gold-quartz vein systems were formed over two billion years ago from magmatic fluids that originated from molten granitelike bodies deep beneath the surface of the Earth. This theory is contrary to the widely held view that the systems were deposited from metamorphic fluids, that is, from fluids that formed during the dehydration of wet sedimentary rocks. The recently developed theory has considerable practical importance. Most of the gold deposits discovered during the original gold rushes were exposed at the Earth’s surface and were found because the y had shed trails of alluvial gold that were easily traced by simple prospecting methods. Although these same methods still leas to an occasional discovery, most deposits not yet discovered have gone undetected because they are buried and have no surface expression. The challenge in exploration is therefore to unravel the subsurface geology of an area and pinpoint the position of buried minerals. Methods widely used today include analysis of aerial images that yield a broad geological overview, geophysical techniques that provide data on the magnetic, electrical, and mineralogical properties of the rocks being investigated, and sensitive chemical tests that are able to detect : the subtle chemical halos that often envelop mineralization. However, none of these high-technology methods are of any value if the sites to which they are applied have never mineralized, and to maximize the chances of discovery the explorer must therefore pay particular attention to selecting the ground formations most likely to be mineralized. Such ground selection relies to varying degrees on conceptual models, which take into account theoretical studies of relevant factors. These models are constructed primarily from empirical observations of known mineral deposits and from theories of ore-forming processes. The explorer uses the models to identify those geological features that are critical to the formation of the mineralization being modeled, and then tries to select areas for exploration that exhibit as many of the critical features as possible. 1. The author is primarily concerned with . A. advocating a return to an older methodology. B. explaining the importance of a recent theory. C. enumerating differences between two widely used methods D. describing events leading to a discovery 2. According to passage, the widely held view of Archean-age gold-quartz vein

2015河海大学考博英语历年真题 一、招考介绍 从整体上看，由于博士生招生形势的不断发展各院校博士生入学考试的难度越来越大，对考生的外语水平要求也越来越高，特别是听、说能力。攻读博士学位的学生，一方面应该具备坚实的专业理论基础和扎实的科研能力，另一方面还应该具备较高水平的外语能力。 二、河海大学考博英语题型 初试的笔试科目为外国语(听力测试在复试中进行)、政治理论和两门业务课，其中英语试题构成一般为词汇结构10%，填空及改错10%，阅读40%，写作和翻译40%。 三、考博英语必备参考书 育明考博教研部主编,河北大学出版社出版的《考博英语真题解析》和《考博词汇》是考博人必备的两本书。在当当网，亚马逊和全国各大书店均有销售，也可以联系我们直接购买。 四、联系导师 在初步定好考博学校之后，就要和所报考院校中意的老师取得联系，询问是否有招生名额，能否报考，这是我们考博成功的关键第一步。 大多数考生会在九月中下旬与导师取得联系。因为太早，学校里面直博名额什么的还没有确定，报考的导师也不清楚是否有名额；太晚的话，怕别的学生比你早联系就不好了。一般情况下，导师对一个学生很中意的话，后来联系的学生，导师一般也不会答应其报考了。在此说点题外话，联系导师的过程中，如果读研期间的导师有关系，可以尽量利用。如果没有，也没关系，凭着自己的本事也是可以和考博导师很好的沟通的，这就要看自己了。 通常跟导师初次联系，都是发邮件。导师回复邮件的情况一般有几种： （1）、欢迎报考。这种答复最笼统，说明不了问题。我们可以接着努力和老师多沟通，看看具体的进展，避免出现初试之后却没有名额的情况。 （2）、名额有限，可以报考，但有竞争。很多人说这样的回复不满意，认为希望很小一般会被刷。其实这样还是比较好的一种回答，最起码导师没有骗你而且给你机会去证明自己，考的好就可以上。 (3）、你的研究方向和我一样......各种一大堆他的研究方向和你相关，欢迎报考什么的话。不可否认，这是最好的情况，你可以放心的去考，一般不会出问题的。但不排除偶然，像出现直博和本
