I guess I was so nervous that I forgot to talk about a lot of stuff that were prepared before. And I was afraid that my poor accent and pronounciation were too bad for mates to follow. Fortunately, some pictures from my ppt saved my life, cause people seemed interested in these images of China's capital. And that made me less embarrassed.
It is urgent for me to practice more oral English and the stand-in-front-of-guys confidence.
A really long way to go. I know.
