Dear Worried:
I heard that you were worried about your English study. I think you really don't be upset. You have the ability to study well.To improve your English is not very difficult. However, you need to spend time on it. In additon, knowing some accustomed expressions and sentence structures is also important, such as let somebody do something, mind somebody doing soething, and so on. I think you can organize some expressions and make them some sentences. That can help you a lot. Another important thing is reading more informations is good for your study. I also strongly recommand that you'd better recite some good passages.
Yours sincerely
