×年×月×日×节课,源源(our数学teacher)的一句话让昏昏欲睡的我精神为之一振。欲问迷津何处有,吾辈遥指杏花村。(一)你看这位老兄像什么?箭?还是十字架?它在解析数学中有个好听的名字叫坐标轴。我佩服它的伟大和崇高,它总是被人践踏,让人在它身上表现性质,大小和方向,可以说是做牛做马,鞠躬尽瘁,有点臧克家《有的人》的牺牲精神,可敬可叹! Year of the year, month, day, day, lesson, the words of our (teacher of mathematics) make the spirit of drowsiness sleep. To ask where the maze is, our generation is pointing to Heng Fa Chuen. (A) What do you think the old man is like? Arrows or crosses? It has a nice name in analytic mathematics called the axis. I admire its greatness and loftyness. It is always trampled on, and people can express their nature, size and direction in it. It can be said to be a cow, a horse, and a kind of trick. Alas!
