Last Friday,we had a lesson and it was really unforgettable because it was the last lesson giving by our kind English teacher,Mr.Tang.When Mr.Tang slowly went into the classroom,we could see clearly that what was hard for him to leave us though he has taught us for only three months.We all listened carefully for every word he said.If only we had behaved like this before!The naughty boys who unusually did well that day.All of us had the common feeling that we wouldn't let her go.As the saying goes,"Only when we lose something will we realize the value of it."At last,the bell ring.Mr.Tang looked at us gently but hoped that we would make progresses in our study.What unforgettable lesson!
