How to improve the English level?  Nowaday I just find that it is becoming more and more important to learn English well.
Because I am working in an export department and I should always talk with our customers who usually speak English. 
My English is just so so although my major is it as a Chinese.
I am good at the grammar but my oral English is not so good.
And I think I should enlarge my English words as soos as possible.
Please share your good ways of enlarging the English words with me 
Thanks so much.

By the way, I always read some English news .
I will write down the words I do not understand on my notebook . And I will look it up from the dictionary.
Please give me your better ways
Thanks so much!
