你老是失踪英文怎么说呢

"失踪" (shī zōng) 在英文中常用 "missing" 来表示。这个词的来源是源于中世纪拉丁文 "missus"，意思是 "缺席、遗失"。例句如下：

The popce are searching for a missing person. (警方正在寻找一个失踪的人。)
The hikers have been missing for three days. (这些徒步旅行者已经失踪了三天。)
My keys are missing. I must have left them at the office. (我的钥匙不见了。我一定把它们留在办公室了。)
