大诗人杜甫正是由于对事物的观察入微,才能写出“细雨鱼儿出,微风燕子斜”这样写景状物的佳句;德国数学家高斯十岁时之所以能很快算出1+2+3+…+100的和,首先在于他观察出这道题的特征.因此,观察力是发展思维能力的一个重要方面.初学解一元一次方程时,在熟练基本解法的基础上,只有认真观察方程的结构特征,才能寻求巧解, The great poet Du Fu was due to the observation of things, and he could write a sentence like “Dripping Rain Fish Out, Breeze Swallows Squinting”; the German mathematician Gauss could quickly calculate 1+2 when he was ten years old. The sum of +3+...+100, first of all, is that he observes the characteristics of this question. Therefore, observation power is an important aspect of the development of thinking ability. When beginners solve a one-element equation, on the basis of skilled basic solutions, only serious Observe the structural features of the equation to find a solution.
