I think the key to improving spoken English, as simple as it sounds,

is practicing every day.  A lot of Chinese people feel that this is

impossible or impractical, because they don't have access to a

foreigner or even a Chinese language partner every day.  It's

important to remember, though, that you can practice speaking on your

own as well.  You can repeat after tapes, movies, or TV shows; you can

read out loud from a book;  you can even record yourself giving a

short speech on a topic.  Of course, it is important to practice by

communicating with others, but you can also do a lot on your own.  At

least a little bit every day.

 

Hope that is helpful.
