Dear Zhang Wei,
You have no idea how happy I was to receive your email. I am writing the letted in purpose of giving some practical suggestions on how to improve your English.
First of all, in my humble opinion, in order to get higher scores in English exam, it could be wise for you to make a detailed plan to enlarge your vocabulary according to your present level, since vocabulary is the foundation of learning a language. Reading is one of the best ways of improving your vocabulary.Besides, the listening part may be the most difficult part for all of us. It is imperative for you to do more listening exercises Like listening to the radio and CDs in English and watching English movies to get familiar with the pronunciation and the usage of words.
I do hope the above advice can be helpful. I am looking forward to your reply.
Yours Sincerely,
Li Ming
