运费上涨英文

不是所有的运费都可以说是shipping的，像是卡车运输就容易混淆，我建议用freight来代替How come the freight charges increased so much lately?还有楼上的，油价已经从最低的37一桶涨到50了

why is the shipping price more expensive than before?

I'd like to find out why the shipping cost has increased so much lately (while gas prices are falling).这样说比较符合商业习惯，如果用中文直译成英语，会让人家觉得你是在问罪一样。后面括号中是我加的，即现在油价在下降（为什么你们运输的价格还在涨）。

运费价格会上涨500到1000美金The price of freight will rise 500 to 1000 dollars
