I am teaching a Business English course in a university in China. And I found it was more challenging that I had expected.  40 students' English proficiency levels vary, though all of them shout that they need to learn business English! 
Having taught "general English" for a while, I am wondering what are the differences between "general English" and "business English" in terms of the content you have to cover in each class? 
Also, I'd appreciate if somebody can recommend a good textbook about business English that I can buy in China.  Thanks!
