雅思閱讀中的邏輯關(guān)系詞

　　hews在其Oxford Concise Dictionary of Linguistics (Oxford University Press) 一書中是這樣描述的：Any of a variety of units whose function is within a larger discourse rather than an individual sentence or clause: e.g. but then in But then he might be late. “discourse marker”雖然范圍更加廣泛一些，但從以上文字不難看出，它包括了我們所熟悉的邏輯關(guān)系詞(即文章中用于表示并列，轉(zhuǎn)折，舉例，因果，遞進(jìn)，讓步，總結(jié)等邏輯關(guān)系的固定單詞或詞組)。

　　也由此可見，特別重視形式邏輯和思維分析的英語行文，在詞語之間和句子之間往往會借助各種邏輯關(guān)系詞清楚表達(dá)思維邏輯和語意關(guān)系。因此了解和掌握邏輯關(guān)系詞可以幫助我們把握文章中語意的轉(zhuǎn)換和發(fā)展，理解文章重點(diǎn)表達(dá)的意思。

　　具體到雅思閱讀，邏輯關(guān)系詞在解題中體現(xiàn)出兩大功能 ：

　　一、語意推斷

　　語意推斷主要是運(yùn)用于重點(diǎn)題型之一的摘要題(Summary)。具體是指根據(jù)空格所在句及前后句的邏輯關(guān)系詞，分析詞語之間，句子之間的語意關(guān)系，推斷出所缺單詞的大致含義。

　　例如：

　　1.劍4 / P77 / Q38

　　Some corpora include a wide range of language while others are used to focus on a particular linguistic feature.

　　根據(jù)while這個表示對比或轉(zhuǎn)折的邏輯關(guān)系詞，可以判斷它前后部分是對比或反義關(guān)系。“a wide range of language”指的是語言研究的廣泛的各個方面，可以預(yù)判空格處應(yīng)是指具體的方面。

　　2.劍1 / P20 / Q4-5

　　The very first fire-lighting methods involved the creation of friction by, for example, rapidly rotating a wooden stick in a round hole.

　　根據(jù)介詞“by”和“for example”這個表示舉例的邏輯關(guān)系詞，可以預(yù)判第二個空格應(yīng)是和“creation of friction”(產(chǎn)生摩擦)的具體動作有關(guān)的詞。

　　3.劍1 / P20 / Q6

　　The use of percussion or persistent chipping was also widespread in Europe …

　　根據(jù)表示并列的邏輯關(guān)系詞or，可以判斷它前后部分是并列關(guān)系。Chipping是“削，鑿”的意思，可以預(yù)判空格處應(yīng)是類似意思的詞。

　　二、定位

　　根據(jù)對歷年真題的總結(jié)分析，雅思閱讀考試的一個重要規(guī)律是：題干中的句子之間，詞語之間的邏輯關(guān)系在原文中一般不變(但表現(xiàn)方式可能會變)。這一規(guī)律使得邏輯關(guān)系詞可以有效地協(xié)助題干關(guān)鍵詞在原文中定位答案信息源。尤其在摘要題(Summary)中這一方法使用頻率很高。

　　例如：

　　1.劍5 / P50 / Q30-31

　　題干：In Britain, moreover, scientists worried that English had neither the technical vocabulary nor the grammatical resources to express their ideas.

　　原文：First, it lacked the necessary technical vocabulary. Second, it lacked the grammatical resources required to represent the world … (Para.7)

　　題干中出現(xiàn)的neither…nor…是連接兩個否定概念的并列邏輯關(guān)系詞。原文中對應(yīng)出現(xiàn)了完全相同的邏輯關(guān)系，即first, it lacked …, second it lacked …(表現(xiàn)方式有所變化)。我們可根據(jù)這種對應(yīng)的邏輯關(guān)系在原文中快速定位答案信息源。

　　2.劍5 / P50 / Q33-34

　　題干：Although English was then overtaken by German, it developed again in the 19th century as a direct result of the industrial revolution.

　　原文：In the following century much of this momentum was lost as German established itself as the leading European language of science. … However, in the 19th century scientific English again enjoyed substantial lexical growth as the industrial revolution created the need for new technical vocabulary.

　　題干中出現(xiàn)的兩種邏輯關(guān)系均在原文中對應(yīng)出現(xiàn)。一是表示轉(zhuǎn)折關(guān)系的although, 對應(yīng)于原文中的however;二是表示因果關(guān)系的as a direct result of 對應(yīng)于原文中表因果的邏輯關(guān)系詞as。很顯然，這對于題干信息的定位意義重大。

　　3.劍5 / P70 / Q25-26

　　題干：To deal with this, Stanley suggests the use of artificial floods in the short term, and increasing the amount of water available through desalination in the longer term.

　　原文：In the immediate future, Stanley believes that one solution would be to make artificial floods to flush out the delta waterways, in the same way that natural floods did before the construction of the dams. He says, however, that in the long term an alternative process such as desalination may have to be used to increase the amount of water available.

　　題干中出現(xiàn)了表示遞進(jìn)的邏輯關(guān)系詞in the short term … in the longer term …。快速查讀原文，可定位于文中相同的邏輯結(jié)構(gòu)in the immediate future … in the long term …。

　　另外，對雅思真題文章進(jìn)行精讀訓(xùn)練的同學(xué)會發(fā)現(xiàn)，除了以上兩大功能之外，邏輯關(guān)系詞在原文中的位置還常常是命題考點(diǎn)最集中的地方。因此學(xué)習(xí)和掌握邏輯關(guān)系詞在閱讀中的功能和作用，將對提高答題的速度起關(guān)鍵性的作用。同時，能夠熟練運(yùn)用邏輯關(guān)系詞對于寫出條理清楚，層次分明的雅思作文也大有幫助。
