我们在书的封底设置了这条提醒语——将它放在你办公桌的一角，这样当你工作时就会首先看到它。

We designed the back cover of this book to be a trigger —set it on the corner of your desk so that it's the first thing you see when you get to work.

您应该能够“阅读”图书的封底内容，查看图书的前言，查看封面图片，以及轻松地(且愉快地)将书放入您的购物车并购买。

You should be able to "read" the back cover of the book, check out the book flap, see the cover art, and easily (and impulsively) drop the book in your cart and wander to the checkout line.

Oops, I have gone too far. This is the back of the magazine.

啊，我扯太远了，这是这本书的封底。
