雅思考試中，閱讀部分的文章是很多變的，但是如果抓住雅思閱讀中幾個(gè)關(guān)鍵的技巧的話(huà)，難度并不高，文章再怎么變也會(huì )有一定內在的邏輯主線(xiàn)，因此雅思閱讀中的邏輯關(guān)系詞就成了抓住主線(xiàn)的一個(gè)重要線(xiàn)索，下面就是小編整理的雅思閱讀中的邏輯關(guān)系詞的兩個(gè)重點(diǎn)。下面和小編一起來(lái)看看吧：
關(guān)于邏輯關(guān)系詞在閱讀中的作用，我們首先來(lái)看一段文字：
the discourse markers signal relationships: between different parts of the discourse … the main reason for studying them is their usefulness in helping the reader to work out the meaning of difficult text. They often show the relationship the writer intends between two parts of the text, so if you can understand one part, the discourse marker is a possible key to the other part. (Christine Nuttall, 1996. Teaching Reading Skills in a Foreign Language, Heinemann)
關(guān)于“discourse marker”，P.H.Matthews在其Oxford Concise Dictionary of Linguistics (Oxford University Press) 一書(shū)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，轉折，舉例，因果，遞進(jìn)，讓步，總結等邏輯關(guān)系的固定單詞或詞組)。也由此可見(jiàn)，特別重視形式邏輯和思維分析的英語(yǔ)行文，在詞語(yǔ)之間和句子之間往往會(huì )借助各種邏輯關(guān)系詞清楚表達思維邏輯和語(yǔ)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(yǔ)意的轉換和發(fā)展，理解文章重點(diǎn)表達的意思。
具體到雅思閱讀，邏輯關(guān)系詞在解題中體現出兩大功能 ：
一、語(yǔ)意推斷
語(yǔ)意推斷主要是運用于重點(diǎn)題型之一的摘要題(Summary)。具體是指根據空格所在句及前后句的邏輯關(guān)系詞，分析詞語(yǔ)之間，句子之間的語(yǔ)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while這個(gè)表示對比或轉折的邏輯關(guān)系詞，可以判斷它前后部分是對比或反義關(guān)系?！癮 wide range of language”指的是語(yǔ)言研究的廣泛的各個(gè)方面，可以預判空格處應是指具體的方面。
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.
根據介詞“by”和“for example”這個(gè)表示舉例的邏輯關(guān)系詞，可以預判第二個(gè)空格應是和“creation of friction”(產(chǎn)生摩擦)的具體動(dòng)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，可以預判空格處應是類(lèi)似意思的詞。
二、定位
根據對歷年真題的總結分析，雅思閱讀考試的一個(gè)重要規律是：題干中的句子之間，詞語(yǔ)之間的邏輯關(guān)系在原文中一般不變(但表現方式可能會(huì )變)。這一規律使得邏輯關(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)
題干中出現的neither…nor…是連接兩個(gè)否定概念的并列邏輯關(guān)系詞。原文中對應出現了完全相同的邏輯關(guān)系，即first, it lacked …, second it lacked …(表現方式有所變化)。我們可根據這種對應的邏輯關(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.
題干中出現的兩種邏輯關(guān)系均在原文中對應出現。一是表示轉折關(guān)系的although, 對應于原文中的however;二是表示因果關(guān)系的as a direct result of 對應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.
題干中出現了表示遞進(jìn)的邏輯關(guān)系詞in the short term … in the longer term …?？焖俨樽x原文，可定位于文中相同的邏輯結構in the immediate future … in the long term …。
另外，對雅思真題文章進(jìn)行精讀訓練的同學(xué)會(huì )發(fā)現，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(shí)，能夠熟練運用邏輯關(guān)系詞對于寫(xiě)出條理清楚，層次分明的雅思作文也大有幫助。
