多個內(nèi)容同時放在一個句子中表達因為英語具備句尾開放性，英語的句子一般較漢語長（陳宏薇 2004）。即便如此，一般知名度高的科研期刊并不歡迎包含很多復(fù)雜長句的稿件，因為科研論文的主要宗旨是清楚明白地傳遞科研信息，使讀者快速高效獲取科研資訊。因此，寫作時要盡量避免用一個句子表達多層意思，或一次表述多件事物（魏爾清 2009）。

例12

誤例：MPM hasmultiple advantages: it eliminates the possibility of damaging the skin whencompared with WCM, and it's a more simple technological flow compared with HuHuaxin’s method; it is a technology that is safe andeasy to perform; as indicated by the quality control test, accurate results canbe obtained via different personnel after a short training period.

改為：MPM hasmultiple advantages. It eliminates the possibility of damaging the skin whencompared with WCM. Also, it's a more simple technological flow compared with HuHuaxin's method. Furthermore, it is a technology that is safe and easy toperform. Lastly, as indicated by the quality control test, accurate results canbe obtained via different personnel after a short training period.

例12 中的誤例十分冗長，給閱讀帶來了較重的負擔。修改后的句子將原句拆分為了五個小句，并適當添加連接用語明確各句之間的邏輯關(guān)系，更加清楚、自然、易于閱讀。一個內(nèi)容嵌套在另一個內(nèi)容中表達使讀者更難理解的是在同一個句子中，一件事物中隱含著另一件事物（魏爾清 2009）。這需要讀者花更多的時間來理清不同事物間的邏輯關(guān)系。

例13

誤例：A sampleof 10 healthy women who were exclusively breastfeeding their babies (age 8~23weeks old) was studied.

改為：A sampleof 10 healthy women was studied. All subjects were exclusively breastfeedingtheir babies (age 8~23 weeks old).

例14

誤例：We beganby performing needs analysis of some visiting scholars who returned from theWestern countries in the affiliated hospitals of our university to identifytheir major needs.

改為 ：We beganby performing needs analysis. We interviewed some visiting scholars who work inthe affiliated hospitals of our university and returned from the west toidentify their major needs.

修改后的兩個句子把隱含在另一件事物中的內(nèi)容抽提出來單獨成句，易于讀者理解。

如何判斷一個句子是否是長句？實際上，通過句子的長度可以辨識句子是不是長句——超過60個單詞就是長句。但是，一個句子如果表述的內(nèi)容過多從而使得論點變得不清晰，即使沒有那么多單詞它也是長句。通過限定每一個句子只說明一到兩個話題，可以避免文章出現(xiàn)過長的句子，注意which, that的用法，若容易產(chǎn)生誤解，請另起一段?？傊?，我們要盡量讓句子簡潔明了，意思清晰。加QQ：3398234353，體驗下SPE學(xué)術(shù)翻譯的語言功底吧~
