买卖的英文可翻译为transaction，business，sale，deal，都有交换、交易的意思。
比如：
The money he got from his father was the basis for a new business.
从他父亲那里得到的钱是他做新买卖的本金。
The gipsy grumbled frightfully , and declared if he did a few more deals of that sort he'd be ruined.
吉卜赛人大发牢骚，抱怨说，这样的买卖要是再做几宗，他就要倾家荡产啦。
Your conversation is like a dance in which you and the vendor are trying to getthe most out of a possible deal.
你们的对话就像舞蹈，在其中你们要尽可能从可能的交易中获得更多。
将“买卖”一词分开来看，买的动词英文拼写是“buy”，卖的动词英文拼写是“sell”。
比如：
What you need a printer? How much they intend to buy this printer?
您需要一款怎样的打印机？打算花多少钱购买这个打印机？。
But if you're "pushing" any other product, you are trying to sell it.
但如果你要“推销”其他产品，你就要努力地去卖它。
