关于考试结束时的英语表达，根据具体场景可分为以下几类：

一、常规考试场景

宣布考试结束

- The exam is finally over.

- The test is finished.

- It's time to relax.

表达感谢与祝福

- Thank you for your participation, please wait for the results to be announced.

- Good luck with your results.

- I hope you did your best, now you can unwind.

二、口语考试场景

正式结束语

- The exam is over.

- Thank you for your participation, please wait for the results to be announced.

- The examination is over.

互动式结束

- That's all for the interview.

- Do I need the second interview？

三、其他注意事项

避免模糊表达：

如"the end of the college entrance examination"是短语而非完整句子，应使用"the college entrance examination is over"。

根据身份调整语气：面试时可用更正式的表达（如"Thank you for your guidance"），而普通考试则建议简洁明了。

建议根据实际考试类型选择合适表达，口语考试优先使用礼貌性结束语，普通考试则侧重感谢与放松氛围的营造。
