Jess:This motor oil case is still really slippery.

Ann: Yeah, time for more coffee!

Jess:Sure, why not? I think I want a chocolate chip cookie, too.

Ann: By the way, I heard Kitty's just got in a shipment of Jamaican Blue Mountain.

Jess:So what?

Ann: It's only the rarest coffee in the world! Didn't your momma teach you anything when you were growing up?

rare (a.)

稀有的

A: Is this pottery expensive?

这个陶器贵不贵?

B: Yes, because it's very rare and unique.

贵，它很稀有，也很独特。

slippery (a.)

棘手的。原本意思是「滑溜溜的」，在此为双关语，因为「机油」就是滑溜溜的，而这个案子又很棘手

This floor is very slippery.

这一楼很滑。

shipment (n.)

装载的货物

Did you receive my magazine shipment?

你收到我寄送的杂志了吗?

之后，在办公室里聊天

洁丝： 这个机油的案子还是很棘手。

小安： 对呀，再去喝点咖啡吧!

洁丝： 好啊，有何不可?我想我也要来片巧克力碎片饼干。

小安： 顺道一提，我听说凯蒂咖啡刚进了一批牙买加蓝山。

洁丝： 那又怎样?

小安： 这是世上最稀有的咖啡!长到这么大，你妈从没教过你吗?
