關於邏輯關係詞在閱讀中的作用，我們首先來看一段文字：
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.
關於discourse marker，hews在其Oxford Concise Dictionary of Linguistics 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
雖然範圍更加廣泛一些，但從以上文字不難看出，它包括了我們所熟悉的邏輯關係詞。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藉助各種邏輯關係詞清楚表達思維邏輯和語意關係。因此瞭解和掌握邏輯關係詞可以幫助我們把握文章中語意的轉換和發展，理解文章重點表達的意思。
