请老师帮我修改作文感谢信

Dear Mr. John,

Thanks for your great help with my English study. My English make great progress改为：My English has improved a lot 或者 I’ve made great progress in my English study. I am the 去掉the grateful for it 跟第一句重复. Without your help, its impossible for me to acquire such good achievement. Your positive energy and help have been an inspiration to me.

My mom has told me that you are really busy these days. Please take good care of yourself. Hope to see you soon.

Again thank you for your encouragement and support.

虽然稍嫌太短，但文采不错。为了保持原样，我尽量少改动。有几个地方写的还比较精彩，如：Your positive energy and help have been an inspiration to me.Again thank you for your encouragement and support.

注：红色部分也是改过的内容。
