避免使用不完整或冗長的句式

　　不完整的句式沒有獨立的從句;而冗長的句式則有兩個以上的從句，而這若干從句之間并沒有恰當地銜接。這兩種錯誤都是我們應該努力避免的，具體做法如下。

　　不完整的句式

　　正式寫作中的每句話都必須有獨立從句。所謂獨立從句，就是包含主語、謂語，并且不以下述連詞作為句子開頭：

　　After if than whenever although in order that though where as provided that unless whether because since until while before so that

　　錯誤：Global warming. This is what the scientists and journalists are worried about.

　　正確：Global warming is the cause of concern for scientists and journalists.

　　注意，以并列連詞and、but、or、nor和for作為單句的開頭，則是可以接受的。例如：

　　正確：Most people would agree that indigent patients should receive wonderful health care. But every treatment has its price.

　　冗長的句式

　　在時間緊張的情況下，不少學生寫出來的句子沒有標點連接，或者只有逗號。例如：

　　Current insurance practices are unfair they discriminate against the people who need insurance most.

　　我們有三種修改方法：

　　1)標注句號：Current insurance practices are unfair. They discriminate against the people who need insurance most.

　　這樣，一個獨立的句子就變成幾個獨立的從句。

　　2)標注分號：Current insurance practices are unfair; they discriminate against the people who need insurance most.利用分號把具有獨立意義的句式分開，但同時向讀者表明句子表示的含義之間存在一定聯系。

　　3)利用連詞：Current insurance practices are unfair in that they discriminate against the people who need insurance most.這也是最有效的修改方法，從句仍然是獨立的，同時也表明了從句之間的聯系。

　　出現冗長句式還有一個原因，就是誤用however、nevertheless、furthermore、likewise、therefore等副詞。例如：

　　錯誤：Current insurance practices are discriminatory, furthermore they make insurance too expensive for the poor.

　　正確：Current insurance practices are discriminatory. Furthermore, they make insurance too expensive for the poor.
