Cover letters can be written in various styles and formats. For each situation a certain style would be suitable. A letter responding to a job advertisement would be different to a speculative letter sent to an employer that hires people in your field. You would use a different introduction and include different types of information for both styles.
求職信 的格式和風格可以很多樣。根據具體情況選擇適宜的風格。針對招聘廣告發出的 求職信 和發給特定招聘者的 求職信 必定有所不同，所以必須使用不同風格的自我介紹和個人信息。
Likewise if you were submitting a cover letter, after being referred from a colleague, you would want to explain who you were being referred from. Similarly for an internal position or promotion in an organisation, it would be sensible to explain you currently work for them.
同樣，在同事的推薦后提交了一份求職信，你需要說明誰是舉薦人。這同樣適用一個組織內的內部職位的申請和舉薦，說清楚你現在的工作內容是明智之舉。
Let’s look at the differences between a standard and speculative cover letter.
現在讓我們看看標準求職信和投機求職信兩者的區別。
Firstly a standard covering letter:
第一封標準求職信
Dear Mr. Jones,
親愛的Jones先生，
My name is John Smith and I enclose my CV for consideration for the post of Environmental Engineer, advertised in The Times on October 21st
本人John Smith，申請10月21日發表在泰晤士報上的環境工程師職位，并附以 簡歷 。
The nature of my degree course has prepared me for this position. I became interested in environmental engineering during my second year at University. My course involved an understanding of the water purification industry, which I found most stimulating. I am particularly attracted to Johnsons Engineering Ltd because of the high reputation of your graduate training scheme
我的專業跟這個職位十分對口。在我大學二年級的時候我開始對環境工程感興趣。我的課程主要是涉及水凈化行業。這讓我十分高興。貴公司的研究生 培訓 計劃享有極高的聲譽，這一點大大地吸引我。
During my time as a student I had a variety of part time and vacation jobs, which all developed my sense of working in a team. In particular, my time as a volunteer in a canal reclamation project required me to supervise a small group. I have a strong sense of public responsibility and also the enthusiasm and determination to ensure that I would make a success of this important position
學生時代，我花很多的課余時間和假期用于兼職，并積極提升自身的團隊合作意思。特別是，曾經我作為一個運河填海項目的自愿者，并管理一個小團隊。我有了強烈的社會責任感，并有強烈的熱情和決心去勝任這個職位。
I will be available for an interview at any time, apart from November 4th to 6th when I am attending a wedding in Scotland. Thank you for taking the time to consider this application and I look forward to hearing from you in the near future.
除了11月4號到6號我需要去蘇格蘭參加一個婚禮，其他時間都是可以參加 面試 的。感謝你可以給我一次 面試 的機會，希望很快可以收到您的來信。
Yours sincerely
你最真誠的，
Now let’s look at a standard speculative letter, which you would send if you were enquiring about the possibility of a job. It would, of course, vary according to the nature of the company:
現在再看一封標準的投機求職信，當你想要詢問有無工作機會可以投這封。當然這需要根據公司性質的不同做適當的調整。
