题目

And you will be receiving a refund of the difference of $309.50 plus charges shortly.
请问这句话应该怎么翻译,主要其中的plus我不知道该是什么意思.
我的理解是:你将很快收到被扣钱数与309.50的差额的退款.

答案

And you will be receiving a refund of the difference of $309.50 plus charges shortly.
翻译一个句子：
首先分析句子,提取主干：
you will receive a refund （shortly）.
这句话的意思是：你将收到退款.
然后加上定语
a refund (of the difference 差额 ( of $309.50 plus charges ) )
所以整句话是:
你将立刻收到与$309.50以及手续费差额的退款.
