I thought a lot attending the lecture about gratitude.The follow is what I want to speak to you.
I would like to thank you for all the help you gave me during this past semester. You were alway so patient when I asked you questions. You listened to them carefully and explained everything so thoroughly. You showed me different ways to practice and remember new words and usage. I felt so encouraged and became more comfortable in speaking English. You made the excercise so interesting that I was always very eager to participate and practice. My English has improved so much. How could I thank you enough?! I cannot wait to take your class next semester and keep working on my English.
