Mr.Clarke:I like the coat.How much is it?
我喜欢这件外套。多少钱？ Salesgirl:300 dollars.
300美元。 Mr.Clarke:300 dollars!Are you kidding?It is too expensive!
300美元！你在开玩笑吗？这么贵！ Salesgirl:But,sir, it is a famous-brand coat.It isn't expensive at all,I think.
可先生，这是件名牌外套。我觉得它一点都不贵。 Mr.Clarke:Hmm...will you discount 20% off if I pay in cash?
嗯......如果我付现金，能不能打八折？ Salesgirl:All right.
好的。
Peter:I'd like to get the ball rolling by talking about prices.
我们从价格开始吧。 Smith:Shoot. I'd be happy to answer any questions you may have.
洗耳恭听。我很乐意回答你的任何问题。 Peter:Your products are very good. But I'm a little worried about the prices you're asking.
贵司产品非常不错，但我有点担心你的价格。 Smith:You think we will be asking for more?
你认为我们会要的更多吗？ Peter:That's not exactly what I had in mind. I know your research costs are high, but what I'd like is a 25% discount.
那并不是我想的。我知道你们的研究成本是很高，但我希望能得到七五折。 Smith:That seems to be a little high. I don't know how we can make a profit with those numbers.
太高了。这样的折扣我们没有利润了。 Peter:We said we want 10000pcs over a three-month period. What if we plan orders for a year, with a guarantee?
我们接下来的三个月需要采购10000个，如果我们保证一年的订单怎么样？ Smith:If you can guarantee that on paper,I think we can discuss this further.
如果你能将你的保证写下来的话。我想可以考虑。
