听力原文：Hello, you're listening to KBC Radio. I'm Luther Lee with Travel Tips. Have you ever had to deal with the stress of losing your luggage while traveling？ Here are a few tips to prevent losing the things you need. First, pack light so you don't have to check in any luggage. However, if you do have luggage to check in, make sure you don't include anything valuable or that you'll need within 24 hours in it. Second, put a copy of your name and address inside your luggage in case your baggage tag gets torn off. Third, take a picture of your luggage in case you need to describe it to airline personnel. Last, if you're really concerned about the airline losing your luggage, there are a variety of shipping companies that will ship your luggage to your final destination ahead of time. After our commercial break, I'll tell you about fun activities you can do during your flight.
