用英语写一封信给自己的英语老师,字数120左右

Respectful Miss/Mr xx,
Here is a letter from your student-xxx to ask for your help with my english study.I feel it really hard to remember the english words so that i wonder if you could tell me some better ways in bearing words quickly in mind?I have already tried the one you taught us which is "reading words for 7 times will keep them in mind quickly",but i think it may not be a useful method to me.So i do need your help.May I ?
regards

亲爱的老师：
我是***,我想让你帮助我．因为我背不下来英语单词．您可以教我几个英语快速记单词的方法吗?我试了你教我们的”快速记单词看七变遍”的方法．可是对于我来说不管用．请你帮助我．好吗?
