英语写信作文，只要100词就够了。格式要正确。

Hello Ms Zhang:
I am Li Hua. I am learning English now. But I think it is not so easy. Reading is not easy for me because I don't know many words. I always try to remember as many words as possible. But the problem is that I always forget them after I've memorized them for a while. This has troubled me a lot. I have tried very hard but I still cannot remember them very well. Can you please tell me what I should do to solve this problem? Thank you!
Regards
好懂吧？呵呵
