何谓曲线?正当我迷惑时,数学老师走了过来:“曲线,就是一条弯曲不直的线。”物理老师也走了过来:“所谓曲线,是非常有利用价值的线,像人们上坡走S形路线,会省力!”“曲线嘛,有很深的涵义。比如,某种物质的溶解度随温度的升高而升高,所形成的图像就是一条曲线。”突然,化学老师慢慢踱了过来。接着只听地理老师慢悠悠地说道:“对!是有很深的涵义,就像喜马拉雅山脉一样,它是曲线,但又是中国与邻国之间的‘纽带’!”我望着各 What is a curve? When I was puzzled, the math teacher came over: “The curve is a line that is not straight.” The physics teacher also came: “The curve is a very valuable line, like people. Walking up an S-shaped route will save you effort!”” The curve does have a deep meaning. For example, the solubility of a certain substance increases with increasing temperature, and the resulting image is a curve. The chemistry teacher slowly froze over. Then just listen to the geography teacher saying slowly: “Yes! There is a deep meaning. Like the Himalayas, it is a curve, but it is also the ’link’ between China and its neighbors!”I look at each
