【正确答案】[精彩范文]
Dear Ms Green,
I am writing to express my thanks to you for the many kindnesses you showed me when I was in hospital.
I got sick just two weeks before the final examination. I was so worried that I couldn't take part in the examination. It was you that me to face the illness bravely. So I recovered soon and got good results in my final examination. If it had not been for your timely assistance, I'm afraid I couldn't pass the exam.
Again, I would like to express my warm thanks to you.
Sincerely yours,
Li Ming
