When I was in primary school, I had a big argument         a boy in my class. l can't  remember what it was about, but I have never forgotten the lesson I learned that day. I was         that I was right and he was wrong. However, he        believed that I was wrong and he was right. The teacher decided to teach us a lesson. She came up with a good idea. She brought          of us to the front of the class ,then she placed the boy on one side of her grey desk and me on      .In the middle of the desk was a large, round object (物体).  It was clear for me       that it was black. She asked the boy what color the object was.  "White," he answered in a loud voice. I couldn't believe that the object was white. One more argument started between the boy        me, this time about the color of the object. The teacher told me to go where the boy was standing and told him to come where I had been. We changed       and then she asked me what the color of the object was. I had to answer, "White. " It was then that I         what was wrong. It was an object with two  differently  colored sides, and from his side it was white only, from my side it was black. My teacher taught me a very important 1esson that day: You must stand in other persons' position (位置) and look at the situation through their eyes        truly understand their ideas.
