I'm working for a multinational company, and English is the most important element for ours. Thus, my department give us the chance to study English and the boss hired a foreigner teacher to teach us Business English. I recogonize it is a very good opportunity to improve our English level. Most of the time I'm shy to talk with the teacher. I worried that he could not understand what I said. But it is much surprise that he's chinese is so good. Some times we talk with each other in Chinese. And he can not recogonize the character of Chinese but the pronunciation. And some times I find Pinyin is a good way to study Chinese.
