距离07年1月20号的研究生入学英语考试还有30天，考研的同学越来越紧张了。作为曾经的局内人和今日的旁观者，总想给各位考生做点什么。碰巧一位学生谈起我暑假写的几篇考研阅读文章，告诉我转载率很高，而且这些文章被不少博克采用，怂恿我在最后30天中再写一些文章。我欣然同意，希望从总结、反思和预测三个角度撰写系列文章，给各位考生提供一些帮助。系列文章分三个部分：总结、反思和预测。在总结部分，我将择要概述考研英语各部分的做题方法；在反思部分，我将总结干扰选项的特征；在预测部分，我将提供一些模拟题与答案。第一部分是总结部分，今天总结完型填空部分的答题技巧。
一、基本技巧
做完型填空题的基本技巧就是找线索，因为20个空的答案取决于该空前后的线索。线索主要有三种，所以我把做完型填空题的方法叫做“三线填词法”。这三种线索包括句子本身的线索、句子之间的线索以及全文线索。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；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等。所以要根据不同情况寻找不同线索，然后确定答案。下面以2005年考研英语的完型填空题为例，说明如何根据线索得到答案。

read the following text. choose the best word(s) for each numbered blank and mark a, b, c or d on answer sheet 1(10 points)
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 fact, _5_, 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.
