今天的美国英语体育成语是“take a rain check”。当你需要拒绝邀请，但是你想将来重新安排时间赴约的时候，使用这个习语。这个表达源于户外体育活动；如果一个活动因为下雨而取消了，球迷们收到一个“rain check （原票票根）”，用于下次活动的免费票。

例句：

- 我很想周二和你一起吃午饭，但是我预约了看医生。我可以改天和你吃午饭么？

- 我太累了，不能去看今晚9：30的电影了，但我会改天去看的。

你是否曾不得不改期？当时是什么情况？

Today’s American English sports idiom is “take a rain check.” Use this phrase when you need to decline an invitation, but you want to reschedule it for the future. The expression originates from outdoor sports events; if an event is cancelled due to rain, fans receive a “rain check,” a free ticket for a future event.

Examples:

- I’d love to have lunch with you on Tuesday, but I have a doctor’s appointment. Can I take a rain check?

- I’m too tired to go to the 9:30 movie tonight, but I’ll take a rain check.

Have you ever had to take a rain check? What was the situation?
