用语需彬彬有礼。
Be polite.
自荐书是帮你树立良好第一印象的最佳机会，因此一定要注重礼节。别忘了开头的问候和结尾的致意。你可以这么来收尾：“谢谢您的考虑”、“期待收到您的回复”或“您真诚的XXX”。
Your cover letter is your first and best chance to make a good impression, so be polite. Don’t forget the salutation opening and complimentary close parts. You may conclude your cover letter by“thank you for your consideration”,“looking forward to hearing from you”and“Respectfully/Sincerely/Courteously yours”.
检查拼写错误。
Check errors.
在寄出你的简历和自荐书之前，多花一分钟时间检查拼写错误或逻辑漏洞，这不会是无用功。祝你好运！
Finally, take one more minute to check spelling mistakes or logical flaws of your CV and cover letter before you send them out. Good luck!
