規則： 盡量使用肯定句。
提出論點時語意要明確，避免使用平淡無力、模稜兩可的字詞。Not 應該只用在表達否定或對比修辭時，不要用來規避正面論述，例如：
（×） The Taming of the Shrew is rather weak in spots. Shakespeare does not portray Katharine as a very admirable character, nor does Bianca remain long in memory as an important character in Shakespeare’s works.
（○） The women in The Taming of the Shrew are unattractive. Katharine is disagreeable, Bianca insignificant.
《馴悍記》中的女性角色缺乏魅力，凱瑟琳不甚討喜，畢安卡更無足輕重。
（×） He did not think that studying Latin was much use.
（○） He thought the study of Latin useless.
他覺得研究拉丁文沒什麼用。
（×）He was not very often on time.
（○）He usually came late.
他常常遲到。
在第一個例子中，第一個句子不僅語意不明確，還帶給讀者負面的感受；修正後的版本能簡潔明確地猜測作者的意圖。
上述三個例子都說明了not 這個詞的弱點，不管在何種情況下，讀者讀到「A 不是B」時都不會滿意；他們想知道「A 是什麼」。因此請謹記在心，表達否定語意時，使用肯定句仍是個較好的選擇，例如：
not honest → dishonest 不誠實
not important → trifling 瑣碎的
did not remember → forgot 忘記
did not pay any attention to → ignored 忽略
did not have much confidence in → distrusted 不信任
將否定句和肯定句並置(對比修辭)通常強而有力：
Not charity, but simple jusetice.
這不是救濟，而是簡單的正義。
Not that I loved Caesar less, but Rome the more.
我愛凱撒，更愛羅馬。
除not之外的否定詞語氣通常也較強，例如：
The sun never sets upon the British flag.
大不列顛，日不落國。

英文原文：
RULE11 Put statements in positive form.
Make definite assertions. Avoid tame, colorless, hesitating, non-committal language. Use the word not as a means of denial or in antithesis, never as a means of evasion.
（×）The Taming of the Shrew is rather weak in spots. Shakespeare does not portray Katharine as a very admirable character, nor does Bianca remain long in memory as an important character in Shakespeare’s works.
（○）The women in The Taming of the Shrew are unattractive. Katharine is disagreeable, Bianca insignificant.
（×）He did not think that studying Latin was much use.
（○）He thought the study of Latin useless.
（×）He was not very often on time.
（○）He usually came late.
The first example, before correction, is indefinite as well as negative. The corrected version, consequently, is simply a guess at the writer’s intention.
All three examples show the weakness inherent in the word not. Consciously or unconsciously, the reader is dissatisfied with being told only what is not; he wishes to be told what is. Hence, as a rule, it is better to express even a negative in positive form.
not honest → dishonest
not important → trifling
did not remember → forgot
did not pay any attention to → ignored
did not have much confidence in → distrusted
The antithesis of negative and positive is strong:
Not charity, but simple jusetice.
Not that I loved Caesar less, but Rome the more.
Negative words other than not are usually strong:
The sun never sets upon the British flag.
