Useful learning tool?

Hi all, 

I just read this article, which was interesting from a technology viewpoint but that seemed to indicate it was focused on helping Chinese learners of English. 

Microsoft Research

Because I was interested I ran this Web link (related to bing) from the Article 

EngKoo

When you enter a Chinese word  (I used 辛苦）it brings back a number of example sentences in English and Chinese which could be useful.  I thought I'd post it here in case people would find it helpful and like me had not encountered it before.   I suspect it should work for all levels.
