在连续剧《亮剑》中,李云龙说过这样一句话:“乖孩子一般没出息,淘气包往往能干大事.”为什么乖孩子一般没出息?因为别人让他干什么,他就老老实实地干什么,而淘气包则会投机取巧,少干活,找捷径.在解数学题中这句话也有一定道理哦,偶尔找找捷径,也是一个不错的选择.这不,最近在学习“轴对称”的内容时,我遇到了一道习题:小明从镜子里看到对面电子钟的像如图所示,实际时间是_______.可以这么说,这道题如果靠抽象思维想出答案的话,没个两分钟甚至更多时间应该是完不成的,而我只用了1秒钟,因为我将试卷反过
In the series “Bright Sword,” Li Yunlong said such a sentence: “The deaf kids are generally unpromising, naughty bags are often able to do big things.” “Why does the deaf boy generally have nothing to do? Because what other people let him do, he honestly does something, The naughty bag will be opportunistic, less work, to find shortcuts. In the solution of mathematics, this sentence also has some truth Oh, occasionally find short cuts, but also a good choice. This does not, recently learning ”Axis symmetry" In the content, I encountered an exercise: Xiao Ming saw the image of the opposite electronic clock in the mirror as shown in the figure. The actual time is _______. It can be said that if this question is based on abstract thinking, the answer is not Two minutes or even more time should not be completed, and I only spent 1 second because I reversed the test
