現在讓我們來比較一下下面的三個句子在語氣上有何不同：
A、 I am not only competent to install a filing system that will fulfill the needs of your corporation,but also well qualified to operate it efficiently.(我自信不僅可以設置一套能滿足貴公司需求的檔案分類系統，而且可以有效地進行操作。)
在此句中使用了not only……but also，competent 和well qualified 等詞語，表現得太自信，有夜郎自大之嫌，故不可取。
B、I think that I should probably make a good accountant for your factory.(我想我可能成爲貴廠的一名好會計員)。
此句中的情態動詞should和副詞probably 所表達的語氣都欠肯定，而make(成爲)一詞也缺乏自信，整句話顯得語氣太弱，有自卑感，因此亦不可取。
C、I am confident that my experience and references will show you that I can fulfil the particular requirements of your secretarial position (我相信我的經驗和證明人可以向您表明，我能夠符合貴單位祕書一職的特定需要。)
此句中的confident 一詞語氣肯定，給人一種自信感，而will show 和I can 也無自大之嫌，因而此句用得恰到好處，有特殊風格。
