How to write a letter of help in senior high school English?

Dear teacher:

My name is Zhou Ming. I am writing to you asking for your help. I met many difficulties in learning English. First of all, I found that our text is full of new words that are difficult for me to remember. Besides, the text is too long for me to recite. Besides, grammar is difficult to learn.

Faced with so many difficulties, I have to ask for your help. Can you tell us some good ways to learn new words? It's easier for us to remember them. At the same time, I ask you to teach the text slowly so that ordinary students can catch up with you easily. Also, I want you to introduce some rules and good methods of learning grammar.

I believe that with your help, I will make great progress in my English study.
