學術論文的連接詞

科學文章不僅報告出實驗觀察到的現象,更會深入地討論其背後的機制。因此,解釋原因時的遣詞用字應精準,否則會倒因為果,誤導讀者。Since, As, Because最常用來連接結果和背後原因,但三者的用法很容易搞混。劍橋線上詞典對此有明確的解釋。使用Since和As時著重在結果上,使用Because時則著重於解釋原因上。

反映在科學文章上,As通常用於敘述結果的部分,描述圖或圖表顯示出的資訊。例如”As shown in Figure 1, …”。Since用法和As類似,但後面須加完整子句。若用於Introduction,Since用來強調某原因造成的現象。例如” Since the stroke is the third leading cause of death in the United States, an effective treatment for the stroke patients is urgently needed.”,重點在後面的子句,引出為何要研究治療中風的方法,此句中若用Because替換Since,則語意變成解釋中風的療法被研究之原因,對於文章脈絡之鋪陳大相逕庭。Since更常用於Discussion段,用來強調研究中特別的發現。例如”Since OO is significantly higher than XX, the results  indicate …”。同樣地強調的是子句中研究結果所指出的事情。

使用Because的句子著重於解釋原因,想當然最常使用在Discussion段。在Materials and Methods若要解釋使用特定方法之原因也是使用Because較為恰當。另外,有些文章會以問句做結尾,而答案已在文章前面闡述過了,這時候文法上也應使用Because。科學論文講求的是清楚明瞭、敘述合乎邏輯,而連接詞的選擇應謹慎,才能將研究結果以及理論清楚嚴謹地呈現出來。
