We had a potluck last Friday because some of our studenst will graduate from elementary school soon. They have been to my school for 6 years. It has been for a long time for learning English lessons at my school. There were some parents and students to join this activity. In this activity, I felt that " TIME FLIES FAST" Cuz, I have seen them from little kids to big kis now. Of course, the important thing is that their English abalities have improved a lot. Good luck to my sweet students....
