在英文中,“做过销售”可以用 have experience in sales 或 have a background in sales 来表示。

have experience in sales 是由 have 和 experience 两个单词组成的短语,have 是助动词,意思是“有”;experience 是名词,意思是“经验”。所以 have experience in sales 的意思就是“有销售方面的经验”。

have a background in sales 是由 have 和 a background 两个单词和 in sales 三个词组成的短语,have 和 in sales 的意思同上,a background 是名词,意思是“背景”。所以 have a background in sales 的意思就是“在销售方面有背景”。

下面是一些例句:

I have experience in sales, so I feel confident that I can help the company increase its revenue.
我有销售方面的经验,所以我相信我能帮助公司增加收益。

She has a background in sales, so she is very good at negotiating and closing deals.
她在销售方面有背景,所以她非常擅长谈判和完成交易。

希望以上回答对您有帮助!
