Good Intonation

I can see a lot of improvement on intonation.

As for the oral English, it is a longer process than reading English. But when you get used to the right way to pronounce the word, you will feel the improvement. Before I read NCE, I easily got lost and shutdown when my coworkers talked a topic for long. But I think I can follow up now. I think the acuteness of the ears definitely improved. It is so good than nobody says "pardon me" again over the phone :).
