首先,聽力原文是這樣的
Man:Good morning,I’d like to send this package to India.
　　Woman:I’ll need you to fill in a custom’s form,please.
　　Man:Sure.Contents in detail,erm… sweater,value,erm… 50 dollars.weight?Oh,I don’t know the weight.
　　Woman:Put it on the scale.
　　Man:There you go.
　　Woman:Ok,that’s one pound and a half.
　　Man:Really?How much is that in kilograms?
　　Woman:Oh,over half a kilo.Now,is it in ordinary mail or air mail?
　　Man:Ordinary mail,please.
　　Woman:That’s going to thirteen dollars seventy two.
　　Man:Thank you.
注意問的是
value 包裹價值 所以根據(jù)原文第三行,應該是50 dollars.而最后一句說的是郵費.
希望我的回答能幫到你,如有任何疑問,請與我溝通.那么郵費是$13.72嗎?對！
