考研英语单词不尽其数，且词形和意义多变，想要每个词义都背到，是不可能的。接下来，北京文都考研网小编为帮助考生，通过猜词技巧和方法来攻克这一难题。特意总结了考研英语单词猜词技巧，供考生参考。
1.利用词根词缀
常见的词根词缀是考生必须掌握的，这也是大纲明确要求的。举个例子：geo-作为前缀，表示"地球"，则有了：geography地理学, 地理;geology地质学 。所以如果所猜测的单词是以该前缀开头，则包含于地球相关的意思。over-前缀，表示"越过，超过"，则有了：overcrowded过于拥挤的;overestimate估计过高;overactive过于活跃。由此推测，over-前缀应有超过的意思。
2.利用正向关系或方向关系
如果上下文是正向关系，则能找到同义词或同义解释;如果上下文是反向关系，则能找到反义词或反义解释。总之，很多时候在上下文中都可以找出生词的其他表达法，可能是近义词、反义词、一个解释或一些暗示。
下面来看例子：
In spite of “endless talk of difference,” American society is an amazing machine for homogenizing people. There is “the democratizing uniformity of dress and discourse...
The word “homogenizing” most probably means______.
[A] identifying [B] associating
[C] assimilating [D] monopolizing
该题中你能找到什么关系呢?根据In spite of“尽管”可以断定句内包含反向转折关系，所以homogenizing与前面的difference在上下文中构成反义词，而在四个选项中能与difference构成反义词的只有assimilating“同化”，所以C选项为正确答案。
3.根据例证或举例关系猜测词义
区分论点和论据是考研英语大纲的明确要求，识别例证关系对于考生而言也相对比较容易，也是解决猜词题的一种常用方法。下面来看例子：
Moreover, demographers see the continuing shift south and west as joined by a related but newer phenomenon: More and more, Americans apparently are looking not just for places with more jobs but with fewer people, too. Some instances --
Regionally, the Rocky Mountain states reported the most rapid growth rate -- 37.1 percent since 1970 in a vast area with only 5 percent of the US population.
Among states, Nevada and Arizona grew fastest of all: 63.5 and 53.1 percent respectively. Except for Florida and Texas, the top 10 in rate of growth is composed of Western states with 7.5 million people -- about 9 per square mile.
The word “demographers” most probably means ________.
[A] people in favor of the trend of democracy
[B] advocates of migration between states
[C] scientists engaged in the study of population
[D] conservatives clinging to old patterns of life
根据 Some instances标志词，很容易判定出上下文的例证关系。根据下文的解释，上文demographers提到的两个例证都涉及人口，因此demographers应该是 "人口统计研究方面的人"。只有[C]选项"研究人口的科学家，也就是人口统计学家"是该词的正确含义。当然，考生也可利用识别词根词缀的方法来推测，demo=people, graph=write，-er指人，因而猜出该词是指"记录人口方面数据的人"。这就需要考生具备充分的词根词缀知识。
“词本无意，意由境生”，如何利用单词本身的结构和上下文的结构关系来猜测生词含义，这是一门很重要的学问。它不仅可以帮助我们解决阅读中的猜词题，也可以帮助我们甄别出文中的许多词汇障碍，所以2020考研学子要予以重视!
