英语作文书信开头和结尾的注意事项
    英文回答：
    Opening a Letter.
    Use a formal salutation. The most common options are "Dear Mr./Ms. [Recipient's Last Name]" or "To whom it may concern." If you know the recipient's name, use that instead of "To whom it may concern."
    Be specific about the purpose of your letter. In the first sentence or two, briefly state the reason you're writing. This will help the recipient understand the focus of your letter and determine if it's something they need to address.
    Keep it brief. The opening paragraph of your letter should be concise and to the point. Avoid using unnecessary details or flowery language.
    Closing a Letter.
    Use a closing salutation. There are a few different options for closing a formal letter, including "Sincerely," "Respectfully," and "Regards." Choose the one that best suits the tone of your letter.
    Include your signature. After the closing salutation, leave a few lines of space for your signature. Then, type your full name below the signature line.
    Keep it professional. The closing paragraph of your letter should be professional and respectful. Avoid using slang or informal language.
