2--The ink should be next to the paper clips and thumb tacks in the stationery section, sir.

1--I've looked for, but I didn't see any black ink.

2--Then I'm afraid there's none in stock.

1--Well, I'll settle for blue-black. I'll also take a dozen airmail envelopes.

2--They come in packages of ten or twenty.

1--Give me a package of twenty, then. And where do I find shoelaces?

2--On counter three.

1--Thank you. I never can find my way around this store.

2--I know. It took me three weeks, and work here.

译文：

1--你们有黑墨水卖吗？

2--墨水应该在文具部的回形针和图钉旁边，先生。

1--我找过了，但没找到黑墨水。

2--那我想是缺货了。

1--嗯，那要蓝黑的也可以。我还要一打航空信封。

2--信封分成十只一扎或二十只一扎出售。

1--那就给我二十只一扎的。还有，我去哪儿可以找到鞋带？

2--在三号柜台。

1--谢谢，我在这家商店里总是搞不清方向。

2--我知道。我在这儿工作，也花了三个星期才熟悉。
