I bet no dictionary can beat this reference! It's based on down-to-earth conversations and I had never seen a lot of informal expressions even in my electronic dictionary before. Especially, I was amazed to find there are many colloquialisms which omit subjects such as I, You, and There is(are). Of course, I suppose these things happen in daily conversations and take it as a way of life. But I didn't expect there would be so many! And every explanation is so informative that I can easily guess what they mean. Therefore, this reference may help you interact more smoothly with English-speaking people if you make the best use of it. How about buying this if you are planning to stay or live in English-speaking countries?
