邀请函现已日益普及,因为宴会、聚会和一些社交活动已成为商家和客户间增强沟通的桥梁,而这些活动一般都需要发出邀请函。在措词和格式上,正式商务社交活动的邀请函(如宴会、招待会)都用第三人称(如:用“肯特夫妇热忱邀请”而不用“我热忱邀请”)。一般这类邀请函都注明服饰要求且附有回执。邀请函中的人名和地点必须明确,时间须按读音书写完整(如:Nov. 5, 1999须写成the Fifth of November, Nineteen Ninety Nine等)。 Invitation letters are now becoming more popular because parties, parties, and social events have become bridges for enhanced communication between businesses and customers, and these events generally require invitations. In terms of wording and format, formal business social networking invitations (such as banquets, receptions) use third-person (eg, “Kent couples zealously invite” instead of “I warmly invite”). In general, such invitations are marked with apparel requirements and receipts. The name and location of the invitation must be clear and the time must be written in full (eg, Nov. 5, 1999 must be written as the Fifth of November, Nineteen Ninety Nine, etc.).
