本来我挂了两科，后来外教好心，让我过了（否则我毕不了业了）

所以我想表达一下我的感谢之情，现求一封英文感谢信，多谢各位啦~

Dear Sir,
I have hesitated long time to write to you. Not only want to express my thanks to you to let me pass in this examination,but also I want to tell you how much confidence I get in learning English from this pass .
You know I really don't have much interest in learning English before. No mater how hard I did in remenbering the English words,I always forget it when I want to use it.
As it is more and more important for us to learn English,I have try many times to improve my English but always can't to be satisfied.
No pains no gains. In this year,I have much progress in my English,although it is not good as others,but I am very happy. Now I found I have much more ineterest in learning English.
Before this examination I am so worry about failing to get passed. Maybe you don’t know how excited I am when I got this good news. It is the best news for me in my life.
This pass is so important for me. Not only it is import for my graduation,but also great confidence in my leaning English. I am sure now I find a better way in Leaning it. I will be grateful to you for your help in all my life.
Thank you Dear Sir again,I will take the English learning as a life long learning process!

Best wishes to you and your family!
Yours,
