小学四年级英语日记带翻译奥数课

　　今天，我上奥数课的时候，丁老师给我们讲了一个故事。

　　Today, when I was in the Olympic math class, Mr. Ding told us a story.

　　以前，有一个国家战败了，公主带领一些人逃了出来，逃到一个海岛，公主想向当地的酋长买一大块地安顿下来，酋长给公主一张黑板大小的牛皮对公主说：“你用这张牛皮能围住多大的地方，我就卖给你多大地方。”公主想一想，就把这张牛皮用剪子剪成细条，然后用针缝起来了，在海边围成一个半圆形。这个酋长不得不佩服这位聪明的公主，终于把这片地方让给了这位公主。

　　Once upon a time, when a country was defeated in the war, the princess led some people to escape to an island. The princess wanted to buy a large piece of land from the local chief to settle down. The chief gave the princess a piece of leather the size of a blackboard and said to the princess, "if you can encircle any place with this piece of leather, I will sell it to you." When the princess thought about it, she cut this piece of cowhide into thin strips with scissors, then sewed it up with needles and made a semicircle at the seaside. The chief had to admire the clever Princess and finally gave the place to her.

　　丁老师告诉我们说；“我们现在学过的几种图形中，圆的面积是最大的，下来就属正方形的面积了。大家明白了吗？

　　Mr. Ding told us, "among the graphs we have learned now, the area of the circle is the largest, and then it belongs to the area of the square. Do you understand?
