英语写作请高手帮忙写篇英语作文要求是：TOM现在读大学一年级（中国人）,向他的好朋友jack述说他是怎样学习大学英语的,

Dear Jack,
I'd like to tell you that I'm proud and happy to be a university student. You know I really enjoy studying and talking with friendly people in college. Now, my dream came true.
Since I've been here for a period of time, I do like the life that was on my own. And I also did a good job in some subjects. However, I found I have some problems in learning English.
The first problem I have to concour is grammar. I made lots of garmmar mistakes in speaking and writing, And, since that, writing is another headache for me. I always have no idea about how to put across my thoughts and feelings in the right way, Finally, I really want you to give me some suggestions in listening, Beacuse I hardly understand the slant and phrases when listening the tape, especially,the speed is fast. What I need to do to improve my English level? I need your help.
I will be very obligad if you help me with such problems, Thank you anain!

yours sincerly,
Tom
