Recently, we’ve learned the news what our English teacher is retiring next month. Heard the news, we felt really down and couldn’t help thought of our days together. In our eyes, she is not only a teacher, but also one of our closely friends. During the past three years, we had all grown into hard-working and active learners under her guidance. She has taught us a lot of English knowledges and how be a good citizen. Whenever we had problems, she was always the one we were turned to for advice and help.

We wish her good lucky and happiness in his life after retirement.
