英语高手来啊！！

You know that I am an university student on Grade 2(an--a，u的开头虽是元音字母但不是元音)
liked English very much in those years（这句有点别扭，我个人觉得和前面的一般完成时不要放在一个句子里）
I feel that it is too difficult for me to continual my English.（改成I feel that it is too difficult for me to continual）
hard(hand)cenior（senior)
we have English teachers(have--had)
we have no(no=not any/not a)
Englisn(English)among(among用在这里不是很恰当，改成before可能会好一些）
mang (many)

The most difficult is （The most difficult one is)
ps:我也是学生，所以麻烦楼主斟酌着看

改好了

Dear Jason;

How time flies! How are things with you? I miss you very much.

You know that I am a second year university student. I have studied English for more than seven years and liked English very much in those years.But now I feel that it is too difficult for me to continue my English study. Perhaps one reason is that when I studied in junior and senior schools, we had English teachers,but now we don't have any. Another reason is that I am afraid of speaking Englisn among so many students.The most difficult thing is to learn too mnay new words.I always forget the words that I learned by heart in the past.Can you give me some advice? Thank you.

Looking forward to your reply.
Yours
