"Pack" 在英语中意思是"打包"或"装箱"。 "Luggage" 是"行李"的意思。因此，"pack luggage" 或 "pack one's luggage" 就是"打包行李"的意思。
举个例子：
I need to pack my luggage before my fpght. (我需要在飞行前打包我的行李。)
She is packing her luggage for the trip. (她正在为旅行打包行李。)
We had to pack our luggage quickly because we were running late. (我们不得不快速打包行李，因为我们迟到了。)
