The purpose I make the new collection is that I want to improve my writting level.?

I realised that if I always read english article, but do not write or speak, my english level is being down in a straight linear speed. I don't kown how to express in english some times when my BF asked me some daily dialogue sentense. It is not a good phenomenon for me. Maybe I won't finish my doctor's study successfully if I make no change now.
