the teacher
dear miss brown,
i am writing to express my sincere thanks to you for caring me in the last two years. during the days of being your student, i learn a lot. firstly, your serious attitude towards teaching and our students moves me too much. you inspire and push me to work harder and harder. secondly, i fall in love with english under the influence of you. as a student of science and engineering, i’ve been thinking that english does no good to me, but you help me to find the fabulous glamour of english that leads me to know a totally different world and develop a different way of thinking. finally, your continuous encouragement supports me a lot when i meet challenges or difficulties. you said that everything to the last will certainly become a good thing, if it is not, not yet to the last. every time, remembering your words, i am so inspired to keep going.
above all, i want to say thank you again and please accept my sincere appreciation. best wishes for you.

dear
teacher ,
i am writing to you to express my thanks for your help in learning english and speaking english.
during these days in your class, i have learned much from you and it is very helpful to me. firstly, you let me know what is the west thinking pattern—straight thinking pattern. and, i think, it is very important to understand the west’s thoughts. as you know, this can help me with my examination and interaction with foreigners. secondly, i have got enough confidence in speaking in english from your class and it took me a long time to gain this confidence. now, i always express my ideas in english as possible as i can. it’s great to do that. the last not the least, i find that learning english is not an boring thing as before and i’m interested in studying english which was just a necessary task to pass examinations. reading, listening or speaking all become interesting and i really enjoy it.
above all, i want to say thanks again to you. and thank you for your time.
good luck!
