请听口令用英文怎么说

"Please stand at attention" is the traditional phrase used to give a command for someone to stand at attention, which means to stand up straight with the feet together, arms straight at the sides and the head and eyes facing forward. This phrase is commonly used in the miptary, but can also be used in other settings such as in a classroom or at a formal event.

Here are some examples of how this phrase can be used in a sentence:

"Please stand at attention when the national anthem is played."
"The teacher asked the students to stand at attention before the start of class."
"The sergeant barked out the command for the soldiers to stand at attention."

这个口令是指命令某人站直，脚跟紧贴在一起，手臂直伸在身体两侧，头部和眼睛朝前。这个口令通常在军队中使用，但在其他场合也可以使用，如在教室或正式场合。
