考研英语完形填空三大技巧
导语：完形填空是考研英语中的一个大题型，攻破考研完型填空题型要从三个方面入手，分别是词汇、阅读以及完成完型填空的技巧。
一、词汇是基础
不止是完形填空，考研英语(论坛)学习的过程中，词汇都是基础。完型填空题型的攻克，是以掌握一定的词汇量为基础的。但是掌握词汇并不是仅仅是背过而已，是指能在答题时灵活运用。词汇量的提高并非是数字的简单推理，而应该是灵活应辨的能力。有些同学在记忆词汇的过程中，背熟了若干本考研词汇书之后仍然无法正确做题，并且在写作文的时候经常词义混淆。
很多同学在记单词的时候，会忽略背诵的质量。记单词的时候不要停留在单词的表面意思上，一定要结合例句和文章来理解。同时运用发散思维，记住了动词，遇到不认识的相关的名词、形容词、副词时就要往这个动词的意思上联想。词汇不是孤立的，建议同学们在学习的过程中，不要将词汇的学习和阅读分离开来。
二、阅读是方法
很多高分学员可能都会有类似的感触，单词没有记住，但是仍然得高分。其中的秘诀就是于他们的语感好。所以阅读能力的培养是很重要的。在答题中第一遍可以带着问题浏览全文，这就需要快速阅读的能力。在寻找问题的答案时，又需要又快又准的回到原文中，迅速定位。平时的复习过程中，应该在每个复习阶段，侧重不同的阅读力度。随着复习的深入，逐渐加大阅读量。尤其是快速阅读理解能力，甚至是跳过一些空格，浏览文章，掌握大意的能力。从一定意义上讲，完形填空试题是为阅读理解服务的，其主旨是考查阅读理解能力。
阅读的过程也是培养语感的过程。临近考研，可以多读读真题，把真题里的完形填空和阅读理解作为素材每天读几遍。到了考场上看到考题时就不会那么陌生。
三、技巧为捷径
一般完型填空做题的步骤是四步，看到文章后，先用一、两分钟时间快速浏览全文，把握中心。明了作者意向、态度。注意文章首末句，因为往往文章的中心句在其中。看懂它们会缩短你读懂文章的时间;结合文章空格精读，对于难于动笔的`空格先跳过，通读;串读全文，连贯通顺。对个别难句进行语言结构上的分析，结合你对文章的理解，逻辑推理出选项;最后通读，检查全文。
完型填空不是没有规律可循的。要学会掌握一种“顺藤摸瓜”的方法，也就是寻找线索。句子本身的线索主要指空格前后所要求的搭配、词汇的并列等;句子之间的线索主要指逻辑关系，如转折、因果、递进等;全文线索主要指文章的主题、作者的倾向以及词汇的同义复现，即作者在上下文中以不同的词表达同一意思等。所以要根据不同情况寻找不同线索，然后确定答案。

The human nose is an underrated tool.Humans are often thought to be insensitive smellers compared with animals,1 this is largely because,2 animals,we stand upright.This means that our noses are 3 to perceiving those smells which float through the air,4 the majority of smells which stick to surfaces.In fact5,we are extremely sensitive to smells,6 we do not generally realize it.Our noses are capable of 7 human smells even when these are 8 to far below one part in one million. Strangely,some people find that they can smell one type of flower but not another,9 others are sensitive to the smells of both flowers.This may be because some people do not have the genes necessary to generate 10 smell receptors in the nose.These receptors are the cells which sense smells and send 11 to the brain.However,it has been found that even people insensitive to a certain smell 12 can suddenly become sensitive to it when 13 to it often enough. The explanation for insensitivity to smell seems to be that brain finds it 14 to keep all smell receptors working all the time but can 15 new receptors if necessary.This may 16 explain why we are not usually sensitive to our own smells we simply do not need to be.We are not 17 of the usual smell of our own house but we 18 new smells when we visit someone else's.The brain finds it best to keep smell receptors 19 for unfamiliar and emergency signals 20 the smell of smoke,which might indicate the danger of fire. 1.[A]although [B]as [C]but [D]while 2.[A]above [B]unlike [C]excluding [D]besides 3.[A]limited [B]committed [C]dedicated [D]confined 4.[A]catching [B]ignoring [C]missing [D]tracking 5.[A]anyway [B]though [C]instead [D]therefore 6.[A]even if [B]if only [C]only if [D]as if 7.[A]distinguishing [B]discovering [C]determining [D]detecting 8.[A]diluted [B]dissolved [C]determining [D]diffused 9.[A]when [B]since [C]for [D]whereas 10.[A]unusual [B]particular [C]unique [D]typical 11.[A]signs [B]stimuli [C]messages [D]impulses 12.[A]at first [B]at all [C]at large [D]at times 13.[A]subjected [B]left [C]drawn [D]exposed 14.[A]ineffective [B]incompetent [C]inefficient [D]insufficient 15.[A]introduce [B]summon [C]trigger [D]create 16.[A]still [B]also [C]otherwise [D]nevertheless 17.[A]sure [B]sick [C]aware [D]tired 18.[A]tolerate [B]repel [C]neglect [D]notice 19.[A]available [B]reliable [C]identifiable [D]suitable 20.[A]similar to [B]such as [C]along with [D]aside from

2016考研英语：完型填空都考什么 完型填空在考研英语复习中的位置其实是一个比较尴尬的角色，因为大部分考生会把主要精力放在考研英语阅读和作文的攻克上，相比这两大部分而言，完型填空的分值确实相对较少，但并不等于可以就此放过。在2016考研的战场上，一分可能就是成功与失败的距离。今天我们就通过考研英语真题来看看，完型填空的那个“空”到底想考查什么。 【相关真题】 As many people hit middle age, they often start to notice that their memory and mental clarity are not what they used to be.

2021考研英语完型填空复习 如何复习完形填空?什么时候开始准备? 答：完形填空是考研比较难的一部分，从历年的平均分可看出，每年平均分都在5分左右，低于及格分。又由于完形填空所占分值不高，许多同学都选择避开，复习阅读时顺带复习完形，或者干脆不管，考试时“蒙一水”。这种做法有一定道理，毕竟完型较难，分值不多，就算投入大量时间和精力也不一定能保证多几分。但是，就算如此，完型也不能甩手不管，需要投入一定时间去准备，另外就是了解一些完形填空出题规律以及做题的技巧和方法，争取达到及格分以上。 复习完形建议以真题为参考，立足真题。把完形出现的固定搭配、固定词组整理出来，在你开始接触真题时就该复习完型。一般在9月后开始系统准备、做题为宜。 完形填空有没有做题技巧? 答：完形填空做题技巧历来都是备受同学青睐。对于这种提分不容易，分值比例又较低的部分同学们都倾向于用“技巧”解题。在此要提醒同学们，任何技巧都是建立在基础上的，技巧不能决定成败，但可起到锦上添花作用。同时，下面给大家分享一些技巧： A、完形填空的第一句话作为文章的开篇，告诉我们文章的主题，下面的内容都是围绕它展开，因此第一句都是完整的，我们也要紧抓第一句话，自己所做的选择都应与第一句的意思相一致。另外注意完形填空选的是最佳答案，而不是正确答案
B、学会利用红花绿叶原则做题。完形词汇分为红花词和绿叶词。红花词就是每次出现在真题里都会选;绿叶词就是屡次出现屡次不选。比如说however、although、yet、because等属于红花词。Since、nowthat、what、if only、in case等都属于绿叶词。根据往年经验，利用红花绿叶原则做题能做对2-5题，但同时也有失手可能，失手也是有原因的，因为和后面提到的原则矛盾了。 C、同义原则：在四个选项中，当两个或三个实词互为同义词时，答案往往在其中。当两个或三个虚词互为同义词时，往往都不选。当四个选项都有一个共同意思时，该意思往往不能入选。更多的技巧和原则可参见李老师授课内容。 完形填空选项答案有没有什么规律? 答：根据我们对历年完形填空真题答案的整理和总结，得到答案分布是有规律可循的：A、四个选项都是4-6个之间，四个答案是均匀分布的。B、一般而言，A答案较多(至少五个)C、没有连续三个答案都是一样的情况。D、在五个一组的答案里，至少要出现三个字母。
考研英语完型填空：Use of English 在一篇240~280词的文章中留出20个空白，要求考生从每题给出的4个选项中选出最佳答案，使补全后的文章意思通顺、前后连贯、结构完整 一、完形填空文章的特点 1. 2. 1)主题（focus） 2)导向性或作者态度的倾向性（观点和态度） 3.短文通常包含三部分基本结构 1)主题呈现 ①文首直接点题 ②用引子（如与主题相关的背景，与论点相似或相对立的观点等）引出主题，主题句在文中或文末出现 2)主题展开 ①提出问题或表述观点后，要对其进行分析、论证，即展开主题 ②主题展开方式，主要体现在短文段落的划分（论述的层次）及各段主题的安排（分论点）上 3)作结 ①下结论 ②提建议 ③概括、总结全文 ④描述事件发展的结果、影响 4. 1)总述是对分述的总结和概括-（中心主线） 2)分述是对总述的展开和祥述-（确保主线贯穿全文） 5. 二、考查要求：能够熟练运用考试大纲要求的英语词汇及语法知识 1.语言要素(包括词汇、语法即表达方式和结构) ① ② 2.语段特征(如连贯性和一致性等) ① 四、完形填空考查内容: 1.词汇知识:形近词及近义词的（动词短语、介词短语）辨析；词汇搭配；一词多义 2.语法知识: 句子基本结构；逻辑关系；上下文语法搭配 ①六大逻辑关系：转折、让步、因果、并列、总分、递进 ②六类从句用法：主宾表，定状同 ③介词含义和用法 ④副词的程度与频率 ⑤句子内部语法结构 3.阅读能力:句子内部信息获取；上下文信息获取；上下文语意关系
五、命题特点： 1.一篇完整的文章=未知信息（20处填空）+已知信息，通过已知信息破解未知信息 2.文章的语言难度显然低于阅读理解题，甚至低于大纲样题 3.干扰选项也多是常用词汇，设置时考虑了内容和结构两方面的完整性与合理性 4.命题大大弱化了对词汇及语法的单纯考查，而加重了对语段特征的辨识能力的考查，即加大了测试语篇水平理解题， 特别是上下文衔接题的比列 六、真题当选选项分布特点 1.A、B、C、D的个数在4个到6个之间，5个最常见 2.几乎没有连续3个答案都一样的情况，连续两个答案都一样的情况在0到3个之间 七、解题思路: 1. ①初步把握：篇章主题、文章基调与作者观点、态度，以及文章的脉络结构（段落划分、段落主题、行文逻辑） 2. ①先解答比较容易、有把握的题目 ②先从整体着手，再根据不断增多的文章信息推断细节 3.第三步：基本完成解题后，需要再读全文，已进行检查 4.解题过程中要时刻具备“语篇意识”，注意选项在上下文语境中是否通顺、连贯、合理 八、完形“十二类”标准题型对应解决方法（相关已知信息提示-线索定位分析法） 欲解出一个未知填空，首先需要在文章的已知信息中定位所有与这个未知填空相关联的已知信息点（线索），通过这些已知的信息点的分析总结，推断出未知填空的答案 对整篇文章从结构布局、上下文关系到句子内部结构进行层层分析，从各个层次定位未知填空的相关已知线索，从已知信息破解未知信息 相关已知信息点（提示线索）的分布规律： ①句子内部：每处具体的未知填空都处在一个具体的句子之中，因此与未知填空相关联的已知信息往往处在于此句子 之中，也就是说此未知填空的附近 ②上下文：由于完形文章的上下文之间往往有着明显的逻辑关系，因此一些与填空相关联的已知信息也会分布在此填 空所在句子的上下文中 ③整个意群、段落、文章的结构中：除了看未知填空所在的句子、所在句子的上下句之外。还有一些相关联的已知 信息需要从填空处的整个意群、段落、文章的结构和文章的中心主线所包含的信息去查找
