阅读下面短文, 请根据短文后的要求进行答题。(请注意问题后的字数要求)。

[1]When I was in primary school, I got into an argument with a boy in my class. I have forgotten what the argument was about, but I have never forgotten the lesson learned that day.

[2]I was convinced that "I " was right and "he" was wrong--and he was just as convinced that __________ and "he" was right. The teacher decided to teach us a very important lesson. She brought us up to the front of the class and placed him on one side of her desk and me on the other.

[3]In the middle of her desk was a large, round object. I could clearly see that it was black. She asked the boy what color the object was. "White,"he answered.

[4]I couldn't believe he said the object was white, when it was obviously black! Another argument started between my classmate and me, this time about the color of the object.

[5]The teacher told me to go to stand where the boy was standing and told him to come to stand where I had been. We changed places, and now she asked me what the color of the object was. I had to answer,"White." it was an object with two differently colored sides, and from his viewpoint it was white. Only from my side was it black.

[6]My teacher taught me a very important lesson learned that day: You must stand in the other person's shoes and look at the situation through their eyes in order to truly understand their perspective(看法)
