I hope I could will be able to speak English as well as my mother language

I have learned English for many years, at in the first fifteen years I only learnt English for examinations. I feel felt very tired of English.  But when I was doing my master degree, I got some good new friends and I started to use English to communicate with my foreign friends.  With three years practicing， i can now speak English fluently, but I have a very heavy chinese accent, and still make a lot of mistakes.  I don't know how to deal with this problem, I hope I could will be able to speak English as great fluently as possible.
And Actually I have a dream, that when I have a baby, I could can teach my baby both Chinese and English, but now there a is long way to go for me,w. Who can help me with this, and give me some effective advices. Now I listen to the BBC every day (try Australia Radio National too), talk to my friends in English sometimes, read some English news, but I feel they are not enough, I hope I could can make my dream come true one day.

Some verb tense problems.  Punctuation - space follows a comma or fullstop.  Capital letter starts a new sentence.  In your text some sentences should stop naturally and a new sentence start, but you continue with a comma and a conjunction
