When applying for a job a cover letter should be sent or posted with your resume. If you are not sure what to write,  here are some tips for you:

?Take the job posting and list the criteria the employer is looking for. Then list the skills and experience you have. State how your skills match the job in paragraph form or in a bulleted list.

開門見山，寫明申請的職位和自己具備的資格條件.

?Include your contact information (address, phone, email address) at the top of every letter you write and in the signature of each email message you send.

寫明詳細的聯系方式.

?Personalize your cover letter and, if you can, address it to the individual responsible for hiring. When you don’t have a contact person, address your letters and email messages to Dear Hiring Manager or To Whom it May Concern.

盡量明確收信人

?Write simply and clearly. Your letter should be one page, or less. Each paragraph should contain three or four sentences, at most. Use a 10 or 12 point font that is easy to read like Times New Roman or Arial. Single space your letter and leave a space between each paragraph.

行文簡練清晰

?When you're writing a cover letter or sending an email message to apply for a job it's important to close your letter in a professional manner.

選用正式的書信格式

?Even when applying online or via email, your cover letter needs to be 1)properly formatted, readable, and without any mistakes. 2)Don’t forget to include a Subject in your email message with your name and the job title you are applying for. 3)Include a signature on all your email messages with your name, phone number, email address.

如果是電子信件，格式要清晰，易讀；郵件名應寫明主題； 每封電子郵件都要包括自己詳細的聯系方式。

The easier you make it for the hiring manager to get back to you, the better outcome you’ll have.

總之，這封信越清晰簡潔，你求職成功的幾率就越高。
