Dear friends,
How time flies! It was four years ago that Mr. Smith came to our school to teach us English. Now he has finished his work successfully and tomorrow he will leave for his home.
Mr. Smith works hard and is very strict with us students. As everyone know, his teaching is lively and interesting. Besides, Mr. Smith gives us lots of good advice on how to learn English well. All of us respect him and love his teaching. We think him not only as our teacher but also our friends.
Now let’s express our gratitude and thank to Mr. Smith for his excellent work. We wish him a pleasant journey and good health.
