距離07年1月20號(hào)的研究生入學(xué)英語(yǔ)考試還有30天，考研的同學(xué)越來(lái)越緊張了。作為曾經(jīng)的局內(nèi)人和今日的旁觀者，總想給各位考生做點(diǎn)什么。
碰巧一位學(xué)生談起我暑假寫的幾篇考研閱讀文章，告訴我轉(zhuǎn)載率很高，而且這些文章被不少博克采用，慫恿我在最后30天中再寫一些文章。我欣然同意，希望從總結(jié)、反思和預(yù)測(cè)三個(gè)角度撰寫系列文章，給各位考生提供一些幫助。系列文章分三個(gè)部分：總結(jié)、反思和預(yù)測(cè)。在總結(jié)部分，我將擇要概述考研英語(yǔ)各部分的做題方法；在反思部分，我將總結(jié)干擾選項(xiàng)的特征；在預(yù)測(cè)部分，我將提供一些模擬題與答案。第一部分是總結(jié)部分，今天總結(jié)完型填空部分的答題技巧。
一、基本技巧
做完型填空題的基本技巧就是找線索，因?yàn)?0個(gè)空的答案取決于該空前后的線索。線索主要有三種，所以我把做完型填空題的方法叫做“三線填詞法”。這三種線索包括句子本身的線索、句子之間的線索以及全文線索。句子本身的線索主要指空格前后所要求的搭配、詞匯的并列等；句子之間的線索主要指邏輯關(guān)系；全文線索主要指文章的主題、作者的傾向以及詞匯的同義復(fù)現(xiàn)等。所以要根據(jù)不同情況尋找不同線索，然后確定答案。下面以2005年考研英語(yǔ)的完型填空題為例，說明如何根據(jù)線索得到答案。

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.
