收拾书包怎么说用英语

To pack a bag means to put all of the items that you want to take with you into a bag or suitcase, arranging them in a way that is organized and easy to access. Here are a few ways you could say this in Engpsh:

I'm going to pack my bag for our trip.
Let's pack our bags before we leave for the airport.
I need to pack a bag for an overnight stay at my friend's house.
I'm packing my bag for the conference this weekend.

You could also use the phrase "clean out my bag" or "tidy up my bag" to mean the same thing, depending on the context. For example:

I need to clean out my bag before I go back to school.
I'm going to tidy up my bag before I go on a hike.

I hope this helps! Let me know if you have any other questions.
