1--Mary, come here. I've found the book our teacher recommended us to buy last week.

2--Really? How much is it? Oh, it's 42 yuan! How expensive!

1--You know, it is the best seller for this year. It has had its fifth impression since its publication early this year.

2--How come? I have never seen such a popular book before.

1--Wait a minute. I found there were two printings. The paperback books must be much cheaper.

2--You are right. Let's buy the cheaper one.

1--玛丽过来。我已经找到了老师上周推荐我们买的那本书。

2--真的？多少钱一本？哇，要42元呀。真贵啊！

1--你知道，这可是今年最畅销的书。从今年年初出版以来这本书已经重印五次了。

2--怎么会？我以前从未见过有这么热门的书。

1--等等。我发现这里有两种印刷本。平装本的书肯定要使宜得多了。

2--你说得对。我们就买便宜的这种。
