3.音高（改变你的音调）

Hello my name is____. I'm taking American Accent Training. There's a lot to learn but I hope to make it as enjoyable as possible. I should pick up on the American intonation pattern pretty easily although the only way to get it is to practice all of the time. I
use the up and down or peaks and valleys intonation more than I used to. I've been paying
attention to pitch too. It's like walking down a staircase. I've been talking to a lot of Americans lately and they tell me that I'm easier to understand. Anyway I could go on and on but the important thing is to listen well and sound good. Well what do you think? Do I?

加粗部分是重读的地方，请练习。

真正的美国人是这么发音的
