Dear Lin Feng
I hear that you have some problems with your English study.It's littlehard to learn a foreign language,but ,you must believe in yourself.Now,I will giveyou some advice.
At first,I'm afraid that you should learn the Alphabet again so that you will be able to raed the letters correctly.Second,when you try to remember the letters,use both your mouth and hand.Reading and writing strengthen your impression of letters and are good to your comunicating with others.At last,you should ask your English teacher for help when you hav grammar mistakes.
Learning English is by no means an easy thing,but,you can make it if you have confidence in yourself and keep on working hard.
