GIVE ANSWERS - English

Hi!
Can someone help me with English? I am good in reading and listening but can't fluently speak or write in English. And I really want to change it))
I think for now it would be helpful if you don't have strong accent (I aim to try to take your pronouncing)) and will be pretty shure about tenses, articles, spelling and all this stuff.
I am native in Russian and ready to help you with your learning.
