I just went to cctv-9 and listened their speech.
two broblems
1) word by word
2) no emotion involved
These made their speaking like a robot.
They may be the most excellent English speakers.
So I think these two problems is what all non-native Speakers encounter.
But I want to know how to correct this.
If your answer is practice more, just think about those broadcaster who
have already practiced too much.
