The Encyclopaedia Britannica has been the most prestigious general encyclopedia in the English language for what seems like forever. But it has always been expensive, and a bit stodgy. Today, when people need to look up information, they're likely to just do a Web search, or to consult the free, community-written, online encyclopedia, Wikipedia.

不过，《大英百科全书》并未离我们远去，也没有对这个数码化的世界视而不见。很久以前，《大英百科全书》就推出一个付费网站。在学校研究领域，很多教师和家长往往更信任《大英百科全书》，而非其他那些不那么可靠的资源。现在，《大英百科全书》即将推出一个漂亮的iPad应用程序，涵盖其所有内容，价格却大幅降低：仅每月2美元，每年24美元。这比互联网版本的每年70美元和印刷版本的约1,400美元要便宜得多。（已订阅互联网版本的用户可免费获得iPad版使用权限北京英语口译。）

The Britannica, however, isn't going away, or ignoring the digital world. It has long had a paid website. When it comes to school research, it is often trusted by many teachers and parents over less rigorously vetted sources. And now, it is about to launch a slick iPad app containing its entire content at a greatly reduced price: $2 a month, or $24 a year, versus $70 a year for the Web version and about $1,400 for the venerable print version. (People who pay for the Web version also get access to the iPad app at no extra cost.)

我测试了这款新的应用程序，我真的很喜欢它。与内容拥挤的《大英百科全书》网站相比，iPad版本的界面更干净，内容更有吸引力，而且还有一些新的功能，比如动态的“链接地图”(link map)，能以视觉方式显示不同词条之间的关系。和互联网版不同的是，iPad版没有内置广告翻译公司。

I've been testing this new iPad app, and I like it. It is much cleaner and more attractive than the cluttered Britannica website and sports some nice features, including a dynamic 'link map' showing the relationship between topics in a visual format. Unlike the Web version, it is free of ads. The app is expected to be available in a couple of weeks.
