使用連線詞，讓句子上下連貫

句子要構成篇章，就需要通過一定的連線詞合乎邏輯的聯絡起來。連線詞是指在論文中用來說明上下句或前後句兩個意思之間關係的詞或片語。連線詞通常用於開篇，引出擴充套件句；也可用於句中，尤其是用於較長的複雜句子中，以作為上下文的紐帶；還可用於文末或段末，用於總結上文或結束本段內容。有了適當的轉折詞和連線詞能使句與句之間脈絡清晰、條理自然、邏輯性強，幫助讀者理解論文的思路。常見的轉折詞和連線詞可以用來表示：

1）平行或遞進關係：

and; furthermore;

also; in addition(to);

as well(as); likewise;

at the same time; moreover;

besides; similarly;

both … and …; still;

2）轉折關係：

although; otherwise;

but; to the opposite;

however; while;

nevertheless; yet;

on the contrary

3）目的或因果關係：

as; since;

as a result; so;

because(of); so…that …;

consequently; such…that…;

due to; therefore;

for; thus;

now that;

4）舉例關係：

For example; for another;

For instance; such as;

For one thing;

5）層次、順序關係：

first, second, third, last

firstly, secondly, thirdly, finally(不推薦)

the first, the second, the third, the last

in the first place, in the second place, in the third place, lastly

to begin with, then, furthermore, finally

to start with, next, in addition, finally

first and foremost, besides, last but not least

most important of all, moreover, finally

on the one hand, on the other hand(適用於兩點的情況)

6）解釋說明關係：

in other words

that is

7）歸納、總結：

as a result; on the whole;

briefly; to sum up;

in a word; in summary;

in brief; collectively;

in short; taken together

注意段落佈局的整體邏輯

經常我們要敘述一個問題的幾個方面。在這種情況下，一定要注意文章整體的邏輯結構。

第一段要明確告訴讀者你要討論幾個部份……Therefore， there are three aspects of this problem have to be addressed. The first question involves……The second problem relates to……The third aspect deals with……清晰地把觀點逐層敘述。也可以直接用First， Second， Third， Finally……當然，Furthermore， in addition等可以用來補充說明。

通過提升語言邏輯，讓論文的語言表達更加清楚明瞭，這對於成功發表SCI論文是非常有幫助的，論文作者要十分注重語言表達這一塊，平時要注意提高自己的英文水平。
