在跨文化交际中，临时变更计划需要特别注意表达方式。当遇到需要取消既定约会的情况，可以参考以下结构化处理方案：
➤ 主动说明：
I'm afraid I need to reschedule our meeting due to unforeseen circumstances.
➤ 紧急取消：
Something urgent has come up and I won't be able to make it.
西方交际中更注重提前通知的时效性，建议至少提前24小时告知变更。临时取消时建议补充说明："I truly apologize for the short notice."
I'm coming down with a fever and need to postpone our appointment. Could we arrange another time next week?
要点说明：具体说明身体状况，给出明确改期时间
An unexpected work commitment requires my immediate attention. Let's take a rain check on our dinner plans.
知识拓展：rain check源出棒球赛事延期凭证，现广泛用于改期场景
| 表达类型 | 适用场景 | 示例语句 |
|---|---|---|
| 正式表达 | 商务邀约 | I regret to inform you that we need to postpone the meeting scheduled for... |
| 日常表达 | 朋友聚会 | Something came up last minute, can we push our meetup to tomorrow? |
✘ 错误表达：
I want to cancel our date because I'm busy.
✔ 优化建议：
I need to rearrange our plans due to a scheduling conflict. How about we meet on Saturday instead?
修改要点：避免模糊表述，提供具体替代方案
