听力原文:M1: Good morning. I'd like to send this parcel to Boston by airmail. Inside are two silk scarves and a jade necklace. M2 : OK, you can wrap it up now. Would you fill in this label and stick it on your parcel? Actually, you can send such a small parcel by postal service. It's faster and cheaper than airmail. M1 : How much is it for each of them then? M2: It would be 6. 8 dollars by postal service and 12. 8 dollars by airmail. What is inside the parcel?
