掌握五大邏輯關(guān)系，提高完形準(zhǔn)確率！

　　摘要：考研英語中完形填空的失分率極高，通常一篇文章如果沒有理清上下文的邏輯關(guān)系，可能會(huì)連續(xù)錯(cuò)好幾道題甚至更多。不過，完形填空的上下文邏輯也并不是毫無規(guī)律可循，任何文章總是逃不過五種邏輯，掌握這五種邏輯關(guān)系，提高完形準(zhǔn)確率！

　　?常見的五大邏輯關(guān)系

　　1、對(duì)立關(guān)系

　　包括讓步和轉(zhuǎn)折關(guān)系，常見的標(biāo)志詞和短語有：but，however，yet，on the contrary，by contrast，unfortunately，although，even though，nevertheless，in spite of，regardless of，anyhow，instead of，rather than，not…but等。

　　如2000年完型第41題：

　　He must store a large quantity of grain ___ consuming all his grain immediately.

　　[A]other than  [B]as well as  [C]instead of  [D]more than

　　答案：C

　　解析：此處考查的是邏輯關(guān)系，需要根據(jù)空前和空后來判斷。空前“儲(chǔ)存了大量糧食”與空后“消耗所有糧食”形成對(duì)立關(guān)系，選C instead of.

　　2、因果關(guān)系

　　常用的標(biāo)志詞和短語有：because，for，since，as，thus，hence，therefore，so，so…that，such…that，in order that，consequently，accordingly，due to，thanks to，in response to，on account of，because of，considering that，seeing that，in that，now that，lest，as a result，for this reason等。

　　如2004年完型第34題：

　　More families consist of one parent households or two working parents， ___， children are likely to have less supervision at home.

　　[A]contrarily  [B]consequently  [C]similarly  [D]simultaneously

　　答案：B

　　解析：此處考查的是邏輯關(guān)系，需要根據(jù)空前和空后來判斷?？涨?ldquo;更多的家庭是單親家庭或雙工家庭”與空后“孩子在家很少受到監(jiān)管”之間是因果關(guān)系，故所B consequently.

　　3、并列關(guān)系

　　常用的標(biāo)志詞和短語有：and，or，neither…nor，either…or，not only…but also，likewise，similarly，equally，in the same way，that is to say，as well as，same…as等。

　　如2004年完型第25題：

　　Theories focusing on the role of society suggest that children commit crimes in response to their failure to rise above their socioeconomic status， ___ as a rejection of middle-class values.

　　[A]or  [B]but rather  [C]but  [D]or else

　　答案：A

　　解析：此處考查的是邏輯關(guān)系，需要根據(jù)空前和空后來判斷?？涨?ldquo;沒有成功提升社會(huì)經(jīng)濟(jì)地位”與空后“排斥中產(chǎn)階級(jí)的價(jià)值觀”都可能是“犯罪”的原因，故空前和空后之間是并列關(guān)系，選A or.

　　4、總分關(guān)系

　　常用的標(biāo)志詞和短語有：such as，for example，for instance， to illustrate，as an illustration，to take an example，more specifically等。

　　如2001年完型第31題：

　　The government is to ban payments to witnesses by newspapers seeking to buy up people involved in prominent cases ___ the trial of Rosemary West.

　　[A]as to  [B]for instance  [C]in particular  [D]such as

　　答案：D

　　解析：此處考查的是邏輯關(guān)系，需要根據(jù)空前和空后來判斷?？涨?ldquo;prominent cases”與空后“the trial of Rosemary West”是包含的關(guān)系，總體與部分的關(guān)系，可以選for instance和such as，但for instance后面不能直接加名詞，such as后要直接加名詞，故選D such as.

　　5、遞進(jìn)關(guān)系

　　常用的標(biāo)志詞和短語有：then，besides，additionally，in addition，furthermore，moreover，what is more等。

　　如1994年完型第46題：

　　Too often， careless use of words prevents a meeting of the minds of the speaker and listener. The words used by the speaker may stir up unfavorable reactions in the listener which interfere with his comprehension； hence， the transmission-reception system breaks down.（） inaccurate or indefinite words may make it difficult for the listener to understand the message which is being transmitted to him.

　　[A]Moreover  [B]However  [C]Preliminarily  [D]Unexpectedly

　　答案：A

　　解析：此處考查的是邏輯關(guān)系，需要根據(jù)空前和空后來判斷。此空位于段首，需要考慮本段與上一段的邏輯關(guān)系，上一段提到“careless use of words”給交談帶來的障礙，空后則提到“inaccurate or indefinite words”理解信息造成的困難。前后是遞進(jìn)關(guān)系，故選擇A moreover.
