参考范文：

    We have every reason to be thankful to many people around us.Among them is Mr Liu, a very nice math teacher of mine.

    Last Friday after the lunch bell rang, my classmates went for lunch, but I remained to ask Mr Liu some questions. Half an hour later, most of my classmates came back from lunch, but I was still asking him questions, and he was so patient.

    It was a small act for Mr Liu, because he is always so helpful and kind to us. However, we often take such kindness for granted. In fact, kindness is found everywhere in  our life, and we should always be grateful.
